In addition, water that has infiltrated into the soil as percolating and stratum water must be collected in drainage pipes and kept away from the building structure by being diverted into a drainage ditch, channel or a drainage system. For many years, perforated plastic pipes have been the pipes of choice and have proven their efficiency and long service life in various construction forms. The DIN (10/2009) Piping systems for civil engineering subsoil drainage, Part 1; Plastic pipes standard defines the pipe types, perforation types, materials and other properties and quality characteristics. Under this standard, all perforated pipes must have a minimum water inlet surface of 50 cm²/m, independent of the nominal width and type of perforation. DIN standards: S DIN S DIN EN ISO 9969 S DIN EN ISO

12 Drainage system AGROSIL 2500 Transport Laying Maintenance DELIVERIES AGROSIL 2500 is supplied in 6 m lengths packed in wooden frame pallets. The pallets must be packed exactly on top of one another on transport vehicles and secured against slipping. On the site, use suitable lifting gear to unload and transport the pallets, such as fork-lift trucks or a crane with cushioned slings. Do not unload by tipping or throwing. The storage site should be firm and free of any foreign bodies that might damage the pipes. Stack max. 2 pallets on top of each other and make sure that the wooden frames of the pallets are placed exactly. Stack loose pipes on a level place with displaced sleeves to a max. height of 1.5 m and secure at the sides. Because of the low weight, single pipes can easily be transported by hand and lowered into the trench without being thrown. Shaft material and fittings are supplied loose or on nonreturnable pallets. MACHINING Check pipes and fittings before machining. Damaged parts must be separated. The limit temperatures for transport and laying AGROSIL 2500 PE-HD pipes are between -20 C and +40 C. Use a fine-toothed saw to cut lengths by sawing in the troughs without cutting the profile. With full and partial drainage pipes, after cleaning the sleeves are pushed together dry; with larger nominal widths use a lever where necessary, with a board between the lever and the end of the pipe to protect the surface. With multipurpose pipes and unperforated multi-purpose pipes clean the sleeves, tapered end and sealing ring carefully and use WPS lubricant. When laying the pipes, make sure that the layout is in accordance with the function. AGROSIL 2500 partial drain and multi-purpose pipes have a lengthways coloured marked on the crown. This marking must be exactly uppermost. The filter and backfill material must be inserted carefully and gradually without being tipped from a height. Compacting in the pipeline zone must be done by hand and with lightweight apparatus only. When doing this, make sure that the pipe is not pushed at the sides or upwards out of its correct position (e.g. sand cone, rods, etc.). PIPE TRENCHES AND PIPELINE ZONE The pipe trenches must be excavated taking account of the relevant laying and safety provisions, including S DIN EN 1610 (01/2010): Laying and Testing Sewer Pipes and Conduits (replaces the previous standard DIN 4033) S ATV DVWK-A 139 (01/2010): Installing and Testing Sewer Pipes and Conduits S ZTV A-StB 97 (2006). Additional Technical Contractual Conditions and Directives for Excavations in Traffic Areas S Accident Prevention Regulations issued by Trade Associations The pipe support must be implemented with the planned gradient and degree of compacting. For reasons to do with the static, in the pipeline zone use material from soil group G1 or G2 that is capable of being well compacted and is filter stable (see the section entitled Filter stable installation ). Frequently, for leading percolating water to the perforations of partial drain or multipurpose pipes the lower area of the pipeline zone is to be consist of dense material through which the water cannot seep. For this purpose, use cohesive soil or foil on non-cohesive soil with a gradient to the perforations. For pipe static reasons, with drainage pipes made of plastic the use of concrete for the support and bedding to the perforations is not recommended. Flexible plastic pipes require a supporting layer in a compactable elastic soil material, so that the pipe/soil interplay and the necessary bedding reaction pressure can develop. compact soil 12

13 FILTER STABLE CONTRUCTION Drainage pipes must be laid with suitable filter materials. If this is not done, malfunctions and restrictions on the service life may occur as a result of blocked perforations or deposits of fine soil particles in the pipe. The following general information shows the fundamental background. It is not intended to replace concrete measures based on the local situation, which have to be made where necessary by a specialist planner or in a soil survey. The choice of the filter material and the dimensions of the filter layer depends on the soil in place and the perforation width of the pipes used. The gravel filter layer must be at least 200 mm thick on all sides, even if multiple graduated material is used. If this condition cannot be complied with, a suitably structured geotextile must be used (see Leaflet on using geotextiles and geogrids in civil engineering works for road construction ). S Perforation width of the drainage pipe The grain distribution curve of the filter gravel that is used must have a grain Ø at 85% by weight that is greater than the perforation width of the pipe. The perforation widths of AGROSIL 2500 are between 0.8 mm and 1.4 mm in accordance with DIN INSPECTION AND MAINTENANCE Drainage pipes are inspected and maintained through the appropriate shafts. With its smooth flat bottom, the AGROSIL-CONTROLLER enables inspection cameras and high-pressure flushing nozzles to be easily inserted into the pipe holders. In contrast, VARIODRÄN shafts retain a certain amount of dirt in the collecting space and this can be sucked out easily during cleaning work. When the drainage installation is handed over to the operator there is usually an initial inspection and the system is cleaned as well, if necessary. Following this, inspections and cleaning measures should be carried out at regular intervals to keep drainage pipes ready for use permanently. AGROSIL 2500 drainage pipe and the AGROSIL- CONTROLLER and VARIODRÄN shafts have been verified as being able to withstand the usual flushing pressure of max. 130 bar used in pipe cleaning today. If rotating chains are to be used as mechanical cleaners only round link chains should be used. The pipe cleaners must choose the right apparatus and method of working to ensure that the drainage pipes are not damaged. INSTALLING THE SHAFTS Shafts made by WPS for drainage pipes are constructed as follows: A shaft body with welded sleeves for the inlets and outlets and a sleeve for the shaft pipe, which is inserted into the shaft body. The shaft pipe is to cut to length in the field for the exact installation height (delivery lengths: 1 m, 1.5 m, 2 m or 6 m). The shaft pipe then leads in a single nominal width through to the surface just below the cover. A fine-toothed saw must be used for cutting. The shaft pipes have a 3-Iayer wall construction. Make the cut in the trough at a right angle to the pipe axis so that the result is a straight end without the webs being cut. The position of the corrugations can be seen on the outer surface of the pipes. We recommend marking the cut with a wide marking tape. Heavy duty covers, designed for vehicular traffic (Class B 125 and D 400) These lie on concrete rings outside the shaft pipes. Their weight and the load from the covers must be transferred through the concrete rings into the soil without the shaft pipes experiencing a vertical load either in the installed position or through settling. With covers that are designed for vehicular traffic cut the shaft connector pipe so that there is a minimum clearance of 50 mm between the upper edge of the shaft pipe and the lower edge of the cover. With heavy duty covers, make sure as well that loads cannot be transmitted into the Connector pipes through the substructure. Class D 400 Lay the concrete foundation at least 20 cm thick so that the cover does not lie on the connector pipe. A sliding and separating layer of film or a similar material must be located between the concrete foundation and the connector pipe. 13

14 Drainage system AGROSIL 2500 Guaranteed quality and safety throughout. PLANNING INFORMATION Pipes and shafts for collecting and discharging seepage and surface water must, among other things, conform to the following requirements: RESISTANCE Resistance of the material to water and soils: S For its pipes and shafts WPS uses proven and reliable materials: PE-HD is resistant to surface and seepage water and with its resistance in the range of ph 2 to ph 11 is in extreme cases, also resistant to water contaminated in industrial catastrophes or to water used in fire-fighting activities. On the other hand, it is stable against erosion and the leaching of ingredients and does not pass on any substances to the seepage water or the surrounding soil. COLLECTING WATER FOR DISCHARGE S For collecting the water from the soil, the water inlet surface of AGROSIL 2500 drainage pipes is greater than or equal to 50 cm²/m in accordance with DIN and is independent of the type of perforation. The water inlet surface of a meter length of drainage pipe therefore corresponds to at least the outflow cross-section of a DN 80 pipe! S The profile geometry of AGROSIL 2500 pipes, which has been optimised for use as drainage pipes, provides the inflowing water with secure and permanent flow paths to the inlet perforations in the troughs. The filter-stable bedding of the pipes is absolutely essential for guaranteeing the long-term water collection capacity of drainage pipes. The correct choice and dimensioning of the filter materials depend on the local soil and the hydrological situation at each project site and require great care in the planning stage. FLOW DIAGRAM AGROSIL 2500 DN 350 DN 300 DN 250 DN 200 DN 150 DN 100 GUARANTEE OF MAINTENANCE FACILITIES Standard inspection methods using cameras and cleaning with high-pressure machinery are possible without any problems with the pipes and shafts shown in this catalogue. The drainage pipe AGROSIL 2500 as well as the AGROSIL-CONTROLLER and VARIODRÄN are demonstrably resistant to commonly used high pressure cleaning systems using a cleaning pressure of 130 bar. After clarifying the concrete requirements, it may be necessary to draw up application-based special solutions for particular application and load conditions, for example, those encountered in tunnel construction, with landfills or in industrial and process engineering.

15 DIMENSIONING Outflow of the expected volume of water without damming up: S For calculating drainage pipes check the possible through flow volume for a selected nominal width, given an available pipe gradient, or determine the required nominal width for a volume to be discharged. The internal roughness of the pipes is an important factor for flow losses. Like all plastic pipes with very smooth non-porous inner surfaces, AGROSIL 2500 pipes made of PE-HD have an absolute pipe wall roughness of 0.5 mm. The perforation has only a slight effect on the outflow performance. Partial drainage pipes and multi-purpose pipes are unperforated in the lower area and UP pipes used purely for transport purposes do not have any perforations at all. To take account of socket joints, shafts, positional deviations and perforations, in general a value of 0.5 mm is assumed for the operating roughness kb, and this can be used for dimensioning using the flat rate concept (RAS EW: kb = 0,4 mm). The outflow as a function of the pipe gradient for AGROSIL 2500 can be seen in the diagram (page 14). The basic principles are found in the work sheet ATV-DVWKA 110 Hydraulische Dimensionierung und Leistungsnachweis von Abwasserkanälen und -leitungen (Hydraulic Dimensioning and Performance Record of Sewer Conduits and Pipes), which was revised and published in a new edition in August 2006 (ISBN ). Important information and standards are also contained in the Richtlinien für die Anlage von Straßen (RAS) (Directive for Highway Projects (RAS)), Part Drainage RAS-Ew. DURABILITY AND DIMENSIONALITY Thanks to their material and geometrical parameters, drainage pipes made by WPS display excellent properties for use in road construction and civil engineering projects. The material PE-HD provides a high degree of toughness at cold temperatures and extreme deformation capability without failure, even under dynamic loads. The corrugated wall design ensures maximum stability. In accordance with DIN , the ring stiffness of AGROSIL 2500 drainage pipes is tested under DIN EN ISO 9969 and compliance with the standards in the category SD is guaranteed: DN 80/100 ring stiffness 8 kn/m² SN8 DN > 100 ring stiffness 4 kn/m² SN4 However, these ring stiffnesses are measured values from laboratory tests to verify defined quality criteria. They only provide conditional information on the behaviour of a pipe under concrete installation and load conditions and on permanent suitability for the planned application. The pipe static verification for drainage pipes under the expected load and the soil and installation conditions of a project can be carried out using the relevant calculation provision ATV-DVWK-A 127. Where required, ask for our Project questionnaire for the static calculation of WPS pipes. With the help of a calculation program, your data are used to check compliance with the verification criteria strength, stability and deformation. In general, it is not difficult to carry out this verification for the drainage pipes even under the highest load class SLW 60 and shallower cover. However, a firm support and bedding for the pipes is necessary in accordance with DIN EN 1610 Construction and testing of drains and sewers, RAS-Ew (drainage), ATV/DVWK-A 139, ZTVA-StB 97 as well as ZTV-Ew-StB
