1. Preface

The present "Guidelines for the design, installation and operation of internal sewage systems from polypropylene pipes" is designed to help organizations designing, assembling and operating non-pressure system sewage systems.

Dressing systems in this album are not considered.

It is obvious that the requirements of reliable operations that are presented to systems of engineering equipment in general and to wastewater systems, in particular, in the conditions of a market economy, continue to tighten, and the need to reduce the cost of construction at the same time becomes more and more relevant. With regard to non-pressure sewage pipelines, this means a refusal of volitional solutions in the design, as well as the reasonable calculation of the systems of the intrama sewage.

At the present stage, the optimal material for sewer pipelines is plastic, pipes from which are technically smooth, lungs, comfortable in installation - already in many ways meet the requirements of time.

When determining the diameter of the sewage riser, the possibility of a breakdown of at least one of the hydraulic shutters attached to this riser should be excluded. Therefore, it seems to be an obvious need for a sufficiently accurate determination of the estimated flow rate of the effluent and the technical parameters of the system sewage system. When calculating horizontal tap pipelines, the length and capacity (capacity) of these pipelines should be taken into account and navigate the devices with the maximum drainage duration. Error in determining the estimated flow rate, diameter, the slope in this case leads to the formation of a pipeline blockage.

The method of determining the estimated waste fluid expenditures for objects of various purposes is given in the recommendations "Design, installation and operation of sewage systems from plastic pipes for buildings and microdistrict" (Moscow, LLP "Publishing VNIImp", 2002), hydraulic calculation of non-pressure plastic pipelines - in "Tables for hydraulic calculations of pressure and non-pressure pipelines from polymeric materials" (Moscow, LLP "Publishing VNIIMP", 2002), which are recommended as auxiliary material to this "manual". These Recommendations ... "and" Tables ... "were published by the Stroypolymer NGO training center for regulations and the calculated formulas given in the arrangement of the rules" Design and installation of pipelines of water supply and sewage systems from polymeric materials. General requirements »SP 40-102-2000.

Each of the listed issues (determining the estimated wastewater spending, the calculation and design of sewage risers, the hydraulic calculation of plastic waste pipelines) is a specific task that affects the reliability and cost of the pipeline sewage system.

Of course, the reliability of sewage systems to highly depends on the quality of construction, so it is necessary to know and take into account the specifics of plastic (including polypropylene) pipes, in particular, to the ability to significantly change its length under the action of the temperature of the transported fluid or the environment. The "Guide" provides the necessary information on compensating linear changes in pipelines and the recommendations on the installation of internal pipeline systems of non-pressure sewerage from polypropylene pipes.

Guide also contains a sorting of pipes and shaped parts from polypropylene produced by NGO "StroyPolymer".

2. Technical characteristics of pipes and fittings

NGO "STROYPOLIMER" produces for the systems of domestic sewage pipes on TU 4926-005-41989945-97 "Pipes and pipes from polypropylene for sewage" and shaped parts by TU 4926-010-41989945-98 "Parts shaped polypropylene for sewer pipes" diameters 40, 50 and 110 mm.

The main physico-mechanical properties of sewer pipes from PP production of NGO "StroyPolymer" are presented in Table 1.

Installation of the pipe connections of pipes and fittings from polypropylene (PP) is performed using rubber sealing two-fledged cake rings with spacer liner (DIN 4060). The design and sizes of the rings are given in TU 4926-005-41989945-97. The ability to use pipe products from PP and rubber seals to it, dimensional characteristics and (or) the design of which differ from those indicated in TU 4926-005-41989945-97 and TU 4926-010-41989945-98 must be confirmed by the relevant regulatory -Technical documentation approved in the prescribed manner.

On the pipeline sewage system from polypropylene is allowed to transport drainages with temperatures:

With a short time of drainage (within 1 minute) - to (+ 95) ° C;

Constantly - to (+ 80) ° S.

Pipes and shaped pieces are commercial, each socket has a groove under the rubber sealing ring. The designs and the main sizes of pipes and fittings are presented in section 9 of this "Manual".

Pipes are designed for service life for at least 50 years.

Purpose and scope of application Preface Widespread development of industrial and urban construction, laying of pipeline communications of heat supply, water supply, sewage, reservoir formation, ponds and canals, irrigation of agricultural land and other similar events inevitably UT to the additional man-made lands. In this regard, within recent years, serious changes in the hydrogeological situation in recent years have been noted, due to the development of the process of flooding the groundwater territories. The flooding of urban and industrial territories leads to the formation of new technogenic horizons of groundwater and, as a result, to the flooding of the basements of buildings and structures, the lanching of low-rise areas of terrain, to aggressive impact on the foundations of structures, etc. To protect the ruffled parts of buildings, intra-quarter and urban pipelines and other engineering communications from flooding, soil and other waters should include drainage measures, including the construction of closed underground drainage pipelines - drainage. The drainage of built-up or designated territories is one of the main events for the protection of buildings and structures from subterranean flooding. The main tasks of drainage when protecting the territory from flooding with groundwater interception of groundwater, floating the territory, and ensuring a given norm of its drainage. In accordance with the "Guidelines for the design of drainage of buildings and structures", the drainage device is required: in cases of the location of the floors, technical subliments, intra-ordinary collectors, channels for communications, etc. Below the estimated level of groundwater, as well as in cases where the excess of floors above the estimated level of groundwater is less than 50 cm; Flooring of basements located in the zone of capillary moisturizing when dampness is not allowed in the basement; floors of exploited basements, intra apartment collectors, channels for communications in clay and drum soils, regardless of the presence of groundwater; Floors of technical subcondures in clay and subliblished soils when they are rewarded more than 1.3 m from the planning surface of the Earth, regardless of the presence of groundwater; Floors of technical subcondures in clay and thin soils when they are less than 1.3 m from the planning surface of the Earth at the location of the floor on the foundation plate, as well as in cases where sandy lenses are suitable for the building or located Talveg. In recent years, drainages apply increasingly and more often and in many other cases not listed in. When designing drainage in front of the project organization, there are two tasks: 1. The performance of hydrogeological calculations, the ultimate goal of which is to determine the amount of consumption (inflow) of groundwater; 2. Performing hydraulic calculations, the ultimate goal of which is to determine the diameter and linker of the drainage tube with the total area of \u200b\u200bslots, ensuring the reception and transportation of groundwater in the amount determined as a result of hydrogeological calculations. A large number of works are devoted to solving these tasks (for example, etc.). As for the solution of the first task - determining the estimated costs of groundwater inflows, then this issue has been studied quite in detail and the calculation regulations are given in the "Recommendations ..." of the USSR State Building. As for the second task - hydraulic calculations of plastic pipes, it should be recognized that it is not sufficiently convincing to calculate the drainage calculations. Otherwise, how can it be explained that recommendations on hydraulic calculations of drainages are produced by the formulas of Szi - N.N. Pavlovsky, or Shzi - manning, fundamentally unsuitable for calculating plastic pipes. In addition, the analysis shows that the method of selecting diameters of drainage pipes, by analogy with the calculations of non-pressure sewerage, can be significantly simplified and specifically specifically applied to hydrogeological conditions of construction and products of the manufacturer of these pipes. This manual contains the necessary information on this issue. 2. The technical characteristics of the pipes and the shaped parts of the NGO "StroyPolymer" produces for construction of drainage corrugated two-layer pipes (Fig. 5) by TU 2248-027-41989945-04 with diameters 100, 150, 200 and 250 mm. The main physico-mechanical properties of drainage pipes from polyethylene manufactured by NGO Stroypolymer are presented in Table. 1. The inner layer of pipes is a round-cylindrical sheath with a thickness (depending on the diameter) of 1.1-1.8 mm from low pressure polyethylene (PND), and the outer layer, reliably bonded with the inner, - hollow inside the corrugations from the PND, The wall thickness, height and step of the location of which are also dependent on the pipe diameter (Fig. 1-4).

Currently, pipes are supplied with lengths of 6 m with three slotted slots between each number of corrugations (see. 6, pos. 6) and are connected to each other with a two-strand coupling (Fig. 7). The minimum distances between the axes of the slotted slots, the slots area and their number on the length of the pipe 1m and 6m are presented in Table. 2. For the construction of a drainage in the sands of the average particle size with an average particle diameter, less than 0.3-0.4 mm, as well as in small and dusty sands, the sumps and with a layered structure of the aquifer of the NGO "StroyPolymer" produces drainage pipes in filter wraps. 3. Designing of horizontal drainage from polyethylene corrugated pipes full factory readiness in the development of engineering protection projects of territories and individual structures from soil waters. It is necessary to be guided by the requirements of the following regulatory documents: SNiP 2.01.15-90 "Engineering protection of territories, buildings and structures from hazardous geological processes. . Basic design provisions ", SNiP 2.06.15-85" Engineering protection of territories from flooding and flooding ", SNiP 2.06.03-85" Landliorative systems and structures "and SNiP 2.04.03-85" Sewage. External networks and structures "(in relation). According to the degree of hydrodynamic imperfection (i.e., the drains of the drainaged and imperfect type differ in the nature of the opening of the drainaged aquifer. Horizontal drainage perfect type completely reveal the aquifers and reach the waterproof. Horizontal drainage of imperfect type reveal the aquifer only partially and do not reach their base to the waterproof. Tubular drains are structurally consisting of a perforated pipe and filtering springs. The spray is performed from stone materials. Materials intended for drainage springs should meet the requirements of strength and frost resistance. Gravel and crushed stone erupted rocks (granite, shenitis, diorit, gabbro, porphyr, lipart, basalt, diabases, etc.) with a specific weight of 2.32.7T / m3 or especially strong varieties of sedimentary rocks (silicon limestone and well-stolen, Unreleased sandstones) with a specific weight of 2.0-2.4 t / m3 with a temporary resistance to compression of at least 600 kg / cm2, are suitable for the inner layer of sprinkles. The filtering sprung simultaneously with the waterproof function carries and water protection, preventing sufficiency and draining drainage collectors with particles of aquifer. The design forms of filtering springs and their dimensions depend on the method of developing trenches in which the drains are stacked. Longitudinal drainage sludges are recommended to take at least 0.002 for clay and drum soils and at least 0.003 for sandy soils. The greatest blockages of drainage are determined, based on the maximum allowable velocity of the flow of water in drainage pipes - up to 1.0 m / s. The horizontal distance (in the light) between various engineering communications and drainage is defined in Table 10, SNiP II-89-80 "General plans of industrial enterprises". For the operation of the drainage system on the drainage highway, viewing wells are arranged, the wells are installed in places of rotation of the track, changing the slopes, on the differences, as well as on direct areas after certain distances. In direct areas, the distance between the wells is recommended for pipes up to 150 mm - 35 m, for pipes 200, 250 mm - 50 m. Weightful wells are usually carried out from precast concrete elements. For drainage pipes offered in the album, the diameter of the round well should be taken 1.0 m. With the depth of the drainage of over 3.0 m, the diameter of the wells should be taken at least 1.5 m. 3.1. Determination of the value of the influx. 3.1.1. The second estimated flow of groundwater on the estimated area of \u200b\u200bthe drainage pipeline is defined as the total inflow of water through all the propulsion on the pipeline throughout its calculated length: (3.1.1) where - the estimated influx of groundwater, l / s; Sn is the number of propyl across the entire estimated length of the pipeline; QNP is the bandwidth of one slot opening (the second flow of groundwater through one propyl), l / s. 3.1.2. The bandwidth of one slothing hole is determined by the calculation based on the fact that when water out of the filtering sprinkle through the hole in the inner cavity of the pipe loss pipeline H0 should not exceed 0.5-1 cm. 3.1.3. The throughput of one horizontal slot opening (i.e., located along the forming drainage pipe) is: (3.1.2) where Mg, - the consumption coefficient of the horizontal slot hole; WCH - the area of \u200b\u200bone slit, m2; g - acceleration of free fall, m2 / s; H0 - Power loss when the hole is expired, m. 3.1.4. The consumption coefficient Mg depends on the Rainolds number (Re) and the D17 / T0 ratio, where T0 is the width of the horizontal slit; D17 is the diameter of the particles of the sprinkle layer adjacent to the watercraft surface, corresponding to the 17% content of them in the particle size composition of the grains of sprinkles. The calculated composition of the sprinkles turns on the fractions of the sprinkles larger than 0.4T0. 3.1.5. The Reynolds number is determined by the formula: (3.1.3) where n is the coefficient of the kinematic viscosity of the filtering water. It is accepted equal to m2 / s. 3.1.6. MG Flow coefficient values \u200b\u200bare allowed to define on table 3. Table 3.

The throughput of one vertical slot opening (i.e. located perpendicularly forming the drainage pipe) is: (3.1.4) where, the flooding coefficient, equal to: (3.1.5) where NP and HB - excess of water level above the threshold of the slot, respectively inside Pipes and on the external circuit, m. 3.1.8. The values \u200b\u200bof the flow rate in the vertical slit depends on the relationship and number of Reynolds (Re): (3.1.6) parameter D25 is the characteristic indicator of the pore structure of the filter sprinkle material near the vertical slot and is determined from the calculated composition of the sprinkles, which includes the fraction larger than 0.6T0.

Hydraulic calculation of horizontal drainage. 3.2.1. Hydraulic calculation of horizontal drainage should be performed by the value of the second estimated flow of groundwater. 3.2.2. The bias of the drainage pipeline I should be determined by the formula: (3. 2.1) where: L is the coefficient of hydraulic resistance of the pipeline; V- average fluid flow, m / s; g - acceleration of free fall, m / s2; R- hydraulic flow radius, m; B - a dimensionless indicator of the degree characterizing the turbulent flow of fluid - transitional (b<2) или квадратичный (b=2) При b> 2 should be taken B \u003d 2. (3.2.2) where a is an empirical indicator degree depending on Ke; (3.2.3) (3.2.4) The Renolds Reques number is determined by the formula: (3.2.5) The Reynolds Ref RF is determined by the formula: (3.2.6) where N is the coefficient of the kinematic viscosity of water. It is usually taken equal to m2 / s (water viscosity at 10 ° C); Ke - coefficient of roughness of pipe material. It is taken equal to 0.1 mm. 3.2.3. The distribution of the average velocity of water movement in the section of the drainage circuit-cylindrical pipeline is subject to the dependences: (3.2.7) or (3.2.8) where VN, VP, RN, RP - flow rate and hydraulic radii of water flow with incomplete and complete filling of the pipeline. 3.2.4. The coefficient of roughness of drainage polyethylene pipes, taking into account their operation modes, should be taken equal to Ke \u003d 0.1 mm. Then the parameter according to formula (3.2.3) is: (3.2.9) the values \u200b\u200bare presented in Table 5 and the schedule in Fig. 8. Table 5.

For this purpose, a table or discontinued value (Fig. 8) is to be elevated to a degree of 1 / b, where the parameter "B" is determined by formula (3.2.4). 3.2.5. With a known magnitude of the second diversion of groundwater, the diameter of the drainage pipe is selected by the nomogram (Fig. 9). Fig. 9. Normogram for determining the diameter of the samotane pipeline from two-layer corrugated pipes. To this end, the ruler should connect the value of the diameter with the flow rate and continue the straight line to intersee with a mute scale A, where there is a seat. Then it is necessary to connect the direct line of the filling values \u200b\u200bof the pipeline (H / D) and the water flow rate, so that this straight line passes through a dummy scale. It should be borne in mind that the magnitude of the filling (H / D) in the drainagers should be at least 0.1; In the containers pipes - at least 0.3; in trunk collectors - not less than 0.5, and the speed of water movement is 0.15-1 m / s (in clay soils, the minimum speed is taken equal to 0.15-0.2 m / s; in sand 0.3-0, 35 m / s). In cases where the flow rate (V, m / s) is known, the pipeline filling (H / D) and the second flow flow (q, l / s), the internal diameter value is determined as follows: connect the straight line V and H / D and on its intersection a mute scale and make a serif. Then this serux is connected to a straight line with a value of q and at intersection of the continuation of this line with a diameter scale read the answer. If this diameter value does not correspond to the drainage pipe, they clarify the diameter (in a large or smaller side), connect its value to the straight line with the flow rate and at the intersection of the continuation of this new straight line with a dumb scale and make a new one. Then, using this stitch, refine the values \u200b\u200bof the flow rate V or the filling of H / D. 3.2.6. After the flow parameters and the value of the pipe diameter are refined, its bias is determined by formulas (3.2.1) - (3.2.6) or on the tables of Appendix 1. 3.3. Geotextile filter materials. The use of geotextile materials allows to reduce the amount of filtering drainage overflows and, in certain cases (for example, when laying the Drainage pipes of the NGO "StroyPolymer" in the middle and coarse-grained sandy soils) to completely replace the gravel and rubberous material of the sprinkles of the pipe wrapper by geotextile material. Currently, the range of artificial filtering woven and nonwovens used as shells of drainage structures is quite wide and the nomenclature of these materials is constantly expanding. The most preferred types of geotextiles as drainage wrappers are switches and glass choles. The firmware and felt-like materials made of polymer composites are often less than a rack to the effects of mineralized water, as well as waters containing organic solvents, surfactants, etc. In addition, synthetic textile filtering materials based on fastening fenal formaldehyde knitting not enough racks under conditions of water with Increased temperature. At the same time, for drainage devices that perform the functions of temporary drainage (for example, used drainage, drainage polygons of household waste, etc.), synthetic geotextiles of the type "Fibertex" can be applied (FiberTex). As artificial filter materials, needle filtering polypropylene materials of the Moscow production enterprise of non-woven materials VERYTEX, NII synthetic fiber (VNIISV, Tver), Suvorovskaya factory of volumetric yarn (Suvorov, Tula region), Institute of Wivar (Mytishchi, Moscow region), VNIintm (Serpukhov). At the same time, synthetic geotextiles can be recommended with the following parameters: the thickness of the material at a pressure of 2 edges is 0.95 mm; Surface density - 140 g / m2; Filtration coefficient @ 70 m / day; Pore \u200b\u200bdiameters - D50 \u003d 0.06 mm, D90 \u003d 0.06 mm; Strength 7-8 kN / m.

Glass brands of GBs-g, BB, BB-T, and SE and SE and CC-1 type, and SS-1, and SS-1, and CC-1, and SS-1, and SS-1, are well established in the drainage structures, which are stacked in several layers. Table 6 shows some of the characteristics of materials allowed as filtering wrappers of tubular horizontal drainage. Filtration coefficients of such materials are tens and more m / days. 3.4. Explanations to the development of drawings 3.4.1. Drainages in separate construct trenches are given for the development of trenches in fasteners and in the slopes. With combined trenches (the top - in the slopes, the bottom - in the mounts) of the drainage design are the same as in trenches with fasteners. Drainages should fit into the dried primer, for which in the sandy soils it is used to use needle filter installations, when laying in low-speed soils - water-trailing device with a construction drainage device. When laying a drain in separate trenches, located near buildings and other structures, the stability of the bases of these structures from the displacement towards the drainage trench should be ensured. Fig. 10. Scheme to determine the safe distance of the drainage trench from the contour of a bellped part (foundation) of the structure. The calculation of the minimum safe distance (LMIN) is performed according to the formula where LF is the storage of the foundation, LG is the width of the drainage trench, J is the angle of internal friction of the soil. Drainage pipes of imperfect type, i.e. The spilled above the waterproof is placed on the filtering sprinkle. Pipe drainage perfect type, i.e. Located on the waterproof, they are stacked on the ground-grazing grinding crushed stone, on top of which the sand layer is stacked. Drainage sinking rectangular outlines are arranged using inventory shields manufactured in accordance with the work adopted by the Organization. Drainage springs of the trapezoidal outlines are pumped without flaps with slopes 1: 1. With a layered structure of the dried soil stratum, a portion of the drainage trench is covered with sand by 0.3-0.5 m above a non-impaired level of groundwater. In homogeneous soils with a filtration coefficient of less than 5 m / day, the backflow of the drainage trench is performed on a height of 0.6-0.7 n (where H is the height of the drainage reproduction nose to the level of a non-imminent level of groundwater on the DRAIN line). Sand for reverse filling of trenches should have a filtering factor of at least 5 m / day. 3.4.2. Drainages, combined with workouts under bellulated parts of structures and underground communications (related drainages) Combined drainage gasket in one pit for construction or in one trench with underground communications (accompanying drainage) applies to reducing the scope of work, including a decrease in the volume of ground removal, as well as In order to increase the efficiency of the protective effect of drainage while reducing the cost of its device. The main types of drainage under consideration are victim, reservoir and related drains. Fig. 11. Principal structural schemes of horizontal drainage using perforated corrugated pipes stacked in a trench (single-line drainage). I - with a single-layer spray with sand-gravel material; II - with a trumpet wrap by geotextile material; and - in the trench with vertical walls; B - in the trench with slopes. 1 - trench circuit; 2 - local soil; 3 - backflow of trenches in rico sand; 4 single-layer sprinkling in small rubble; 5 - drainage tube. Fig. 12. Constructive schemes of used drainage using perforated corrugated pipes 1 - hydraulic constructions; 2 - waterproofing; 3 - local soil; 4 - Sandfasting; 5 drainage pipe; 6 - overpopping with small rubble; 7 - sand preparation; 8 - sprinkling coarse-grained sand. Wailed drainage is arranged along the external contour of the underground part of the building, if necessary, protection against flooding of basement or bases of foundations located on the waterproof. Waiting drainages are intercepted and removed both groundwater of lateral tributaries and infiltration water, accumulating in the soils of the backfill of the sinuses of the kittlers, trenches, etc. The reservoir drainages are peculiar filter beds-bed. They are used to protect against the flooding of basements of individual buildings, underground tanks, as well as swallowed communications. The use of reservoir drainage is particularly efficient in low-dimensional soils. In some cases, it is advisable to combine the confused and reservoir drainage. The reservoir drainages are advisable to arrange for interception and removal of leaks from locally located storage facilities and containers with technical solutions, technical liquids and dramatics and dramatics. Related drainies are arranged if necessary to protect against flooding underground collectors, gallery of transport tunnels and other linearly elongated structures. At the same time, the concomitant drainages can combine the design features of traditional single-cereal drains and reservoir drainage. Waterconditions from reservoir, used and accompanying drainage can be carried out in a network of storm sewage or in open reservoirs in coordination with environmental services. 3.4.3. Circuit diagrams The schemes of drainage with the use of perforated corrugated polyethylene pipes are not different from the tubular drainage schemes using other types of pipes that are the basis of the drainage design. At the same time, it should be noted that in the case under consideration the device of drainage structures is based on a pre-(technologically determined) mounted size and form of drainage holes and the design of the drainage design is carried out with already specified parameters of the water-driven holes in the pipe wall. At the same time, the design scheme of the drainage may include a drainage pipe wrapper with a geotextile material with a single-layer sandy sprinkler or a single-layer sprinkle with small rubble (cr. 5-12 mm) with a chicken sprinkle coated with geotextiles. 4. Construction of drainage and acceptance of their operation 4.1. Drainage pipes are placed in a trench, the bottom of which is altered on the level to impart the project line of the project slope, in accordance with the regulations. 4.2. The width of the trench along the bottom is equal to the outer diameter of the pipeline plus 40 cm. 4.3. In cross section, the trench may have a rectangular or trapezoidal outline. In the first case, the walls of the trench are strengthened with inventory shields, in the second - slopes 1: 1. 4.4. The bottom of the trench should not contain solid inclusions (solid lumps, bricks, stone, etc.), which can be traded the bottom wall laid on them pipes. 4.5. Before assembling, drainage corrugated pipes are laid out on the rifle of the trench. All pipes and components pass input quality control. 4.6. The installation of the pipeline is carried out at the bottom of the trench, where each pipe, one in one, is consistently inserted into the socket of the previous, formed by a double-standal coupling, dressed onto its sleek end (Fig. 13). If necessary, the pipe is cut between the corrugations with a tree or metal. 4.7. The installation of the compounds is performed using a lever, restricted into the crossbar, suitable across the cross section of the smooth end of the high-speed pipe. 4.8. At the end of the installation work, the drainage pipeline is covered with so-called drainage springs, which, in accordance with the composition of drainaged soils, can be single-layer and multilayer. When the drainage is arranged in the sands of grave, large and medium size with an average particle diameter of 0.3-0.4 mm and single-layer springs from gravel or rubble are larger; At the arrangement in the sands of medium size with an average particle diameter, less than 0.3-0.4 mm, as well as in small and dusty sands, squeezes and with a layered structure of aquifer, two-layer springs are arranged - the inner layer of rubble springs, and the outer layer - from sand. In such soils, drainage pipes can be used in filter wrappers, and a single-layer spray from gravel or rubble can be applied in these cases. Fig. 13. Mounting of the pipeline The selection of the composition of drainage sprinkles is made by special graphs depending on the type of filter and the composition of the drainaged soils. 4.9. Drainages should be laid in the trenches. Drainage pipes of imperfect type are laid on the lower layers of drainage sprinkles, which, in turn, are stacked on the bottom of the trench. For the drainage of the perfect type, the base (bottom of the trench) is strengthened by the rubble, and the pipes are stacked on a layer of sand with a thickness of 5 cm. 4.10. In weak soils with insufficient carrier ability, drainage must be laid on an artificial basis. 4.11. The thickness of one layer of draining springs should be at least 15 cm. 4.12. Hydraulic testing of drainage pipes are not made. Mounting quality is monitored in the process of assembling the pipeline. At the same time, the project is compliance with the project: its rectinity is achieved using the sinking soil, which serves as a fixer, and the slope is controlled by the level. 4.13. Installation of pipelines is performed at an outdoor temperature to minus 100c. 5. Maintenance and repair of drainage 5.1. Maintenance and timely repair of drainage pipelines to highly contribute to their effective work for the entire settlement service life. 5.2. The operation of drainage is carried out by services of control and supervision, which includes the task. - periodic inspection of drainage devices; - elimination of minor faults; - certification; - systematic observations of the provision of groundwater level on a drainaged area in order to establish the effectiveness of drainage; - quality control of drainage water; - Conducting planned-warning and current repairs and elimination of accidents. 5.3. In the process of periodic inspections (at least four times a year), the state of viewing wells, drainage pipes, collectors, and control measurements of water costs are carried out. 5.4. Control measurements of water expenditures are carried out in the observation wells in a volume of the way. Reducing the consumption (compared with the calculated) indicates a decrease in the bandwidth of the drainage pipes, the reason for which it can be: - the sediment of pipes in separate areas; - damage to pipes; - overlay of pipe cross sections, due to hacking or clogging; - Calcation of the holes of filtering propilov. 5.5. Watching wells must be regularly cleaned from dirt and nanos. Wells should be closed constantly during the entire life of the drainage. 5.6. Drain purification is carried out by hydraulically. If this method does not give effect, the line is shifted. 5.7. Purification of drainage pipes from garbage and nanos is carried out using high pressure hydraulic equipment. Application for these purposes of scrapers and the rod is not allowed. Fig. 14. Designs of wells 6. Transportation and storage of corrugated polyethylene pipes 6.1. Pipes are transported by all types of transport in accordance with the rules for the carriage of goods acting in this type of transport. 6.2. Loading and unloading operations during transportation and laying of pipes in the trench should be carried out by technology that excludes their mechanical damage. 6.3. Transporting pipes is recommended to be carried out in the factory package, which is either a wooden frame, or a metal tape. However, lifting bundles of pipes behind a wooden frame or tape binding is categorically prohibited. 6.4. Bundles of pipes in wooden frames are moved using a fork forklift or lifting crane using a sling of sufficient width. 6.5. Transportation, loading and unloading of pipes is allowed at an outdoor temperature up to minus 25 ° C. 6.6. Pipes are placed by stack on an even base. The maximum height of the pile of pipes in wooden frames is 2.8 m. The maximum height of the stack of separate pipes is 1.0 m. 6.7. Pipes are allowed to be stored in the open air, provided that they are not exposed to direct sunlight, as well as indoors at a distance of at least 1 m from heating devices. 6.8. When the stack device should provide stability of the stack, i.e. Exclude the possibility of rolling pipes. 6.9. Drainage corrugated pipes are forbidden to dump from vehicles, with a stick of trenches, etc. , as well as move the wolf. 7. Requirements for security and environmental protection 7.1. Drainage in the construction should comply with general requirements SNIP III-480. 7.2. Persons not under 18 years old have been allowed to assemble a medical examination, special training, introductory safety instructions and instructing in the workplace. 7.3. Polyethylene pipes in the conditions of transportation, storage and installation do not emit toxic substances into the surrounding medium. With direct contact, the pipe material does not affect the human body. Working with polyethylene pipes does not require special precautions. 7.4. Pipes when applying open fire light up without an explosion and burn with smoking flame. Pipes belong to the group of combustible according to GOST 12.1.044, the flammable temperature is about 300 ° C, the temperature of self-ignition is about 350 ° C. Water, foam and acidic fire extinguishers should be used as fire extinguishing means. Literature 1.
