EN 12484-4:2002 (E)64.2 Contractor storage area4.2.1 Pipe storagePlastic pipes require special transport, handling, unloading and storage conditions, as specified by themanufacturer.4.2.1.1 Basic rulesa) For handling and transport, direct contact with chains, slings or with salient metal objects shall be avoided.Pipes shall be carried and not rolled or dragged over the ground;b) Storage: Pipes shall be stored on a smooth, flat surface. Any contact with petroleum products or heat shall beavoided;c) Recommendation: Seal pipe outlets with tight fitting plastic caps or adhesive tape to keep out stones, otherdebris and animals.4.2.1.2 PVC pipesPVC pipes are made of easy to handle light weight material.At temperatures lower than 0 °C the impact strength of PVC pipes is reduced. PVC pipes can however besatisfactorily handled and laid, when adequate care is taken.To maintain their geometric shape, pipes shall not be stacked higher than the maximum height specified by themanufacturer.When PVC pipes and fittings are stored outside in direct sunlight, the manufacturer's instructions for providingshading shall be followed.4.2.1.3 Storage of materialsLubricant, solvent cement and cleaner containers shall be stored away from any heat source.4.2.1.4 Polyethylene pipesCoil stacking shall not exceed the height specified by the manufacturer.4.2.2Electrical equipment storageElectrical equipment (cabinets, controllers, etc.) shall be stored in a covered and dry place.4.3 StakingIrrigation system staking and implementation shall be made in accordance with the layout plan prepared during thedesign phase.Accurate measurements shall be taken with appropriate topographic equipment adapted to the size of the project.Stakes shall be large enough to permit good visibility.Colour-coded stakes shall be dedicated to each system component.Whenever the location of a component on the plan is open to interpretation or requires on-site modification, stakingshall be checked and approved by the project manager.SIST EN 12484-4:2004
EN 12484-4:2002 (E)74.4 Trenches4.4.1 Locate and protect other worksPrior to any trenching work, the route of the trenches shall be marked out in accordance between the contractor,the owner and the project manager.The location of existing services shall be determined by the main concessionaires, available documents, carryingout surveys, and using detection equipment.The choice and the size of the excavating machines shall be chosen so as to best preserve vegetation and existingstructures.4.4.2 Trench specification4.4.2.1 TimingTrenching shall be phased with other underground installations to avoid them remaining open for too long andpossibly collapsing. Ideally, trenches shall be opened and back filled on the same day.4.4.2.2 Sizinga)Width:Trenches shall have a width adapted for laying or the pipes without excessive excavation.This width shall not exceed 2 times the outside diameter of the pipe;b)Depth:Trenches shall be deep enough to avoid any damage due to soil preparation and maintenance work.Trench depth shall allow minimum cover above the pipe of 0,60 m for main pipes and 0,50 m. for lateral pipesunless ground conditions dictate otherwise.This depth shall also be adapted to climatic conditions and specific requirements as defined by the owner. Thetrench bottom shall be properly levelled so those pipes are supported along their entire length.4.4.2.3 Trench backfillingThe excavation material that may be used for trench backfilling shall be kept on the sides of the trench. If not, itshall be partially or totally removed.a)Bedding: Pipes and wires shall be laid on a 5 cm sand bedding if the trench bottom is not smooth, levelled andfree of stones, rocks or other debris ;b)backfilling around the pipes: Pipes shall be covered with excavation material on condition that it does notcontain stones larger than 10 mm, in their dimension.If such is not the case, pipes shall be covered with 5 cm to 7 cm of sand above the top of the pipe.4.4.2.4 CompactingBackfilling shall be carried out with successive compacted layers of 20 cm in order to prevent the subsequentcollapse of trenches.SIST EN 12484-4:2004
EN 12484-4:2002 (E)84.4.2.5 Warning meshThe colour-coded warning mesh corresponding to the type of material to be protected shall be installed 20 cmabove the top of the work.4.5 Trenches under roads and similar areasTrenches shall be constructed and reinstated according to the specifications and standards laid down by statutorynational authorities.4.6 Pipe installation4.6.1 GeneralThermoplastic pipes are normally used for automatic turf irrigation systems. Other pipe materials are not coveredby this standard.4.6.2 PVC pipes4.6.2.1 CuttingFor pipes cut on site, the end to be jointed shall be cut square and chamfered to produce a finish equivalent to thatof the pipes and fittings supplied by the manufacturer.4.6.2.2 Push-fit pipe joints with automatic sealing (mechanical joints)The satisfactory completion of a push-fit insertion joint normally requires a chamfer on the pipe end and the correctlubrication of the spigot and socket before the joint is made.In any given installation, only those sealing rings supplied by the manufacturer of the pipe and/or fittings shall beused.Jointing instructions shall include but not be limited to the following but in any case shall always follow themanufacturer's instructions:a)the spigot, the socket of the pipe and the ring groove shall be clean and the sealing ring shall be flat andcorrectly fitted into its location;b)the lubricant, which should not be harmful to the PVC or to the elastomeric seals, should be applied over thewhole chamfered end;c)the pipe should be carefully aligned with the adjoining pipe socket and pushed to the required insertion depth.When a lever is used to push the pipe in the socket, a block of wood shall be inserted between the lever and theend of the pipe to prevent damage to the pipe. Where mechanical aids are used to assist jointing, care shall betaken to avoid damage to the pipes;d)ideally pipe should be assembled in the trench. However where this is not possible because of the width of thetrench, pipes may be assembled on the ground. When lowering the pipes into the trench care should be taken tomaintain the integrity of the assembly and avoid impact damage.4.6.2.3 Pipe assembled with solvent cement joints4.6.2.3.1 GeneralThis method of jointing shall only be used for PVC pipe with a diameter of up to 63 mm.The nominal working pressure of PVC pipe assembled by solvent cements joints shall be reduced to the nextlowest class.SIST EN 12484-4:2004
EN 12484-4:2002 (E)9Jointing instructions should include but not be limited to the following but in any case shall always follow themanufacturer's instructions :a)the pipe spigot end and the socket shall be roughened using abrasive paper and cleaned with cleaning solventrecommended by the pipe or fitting manufacturer;b)the solvent cement recommended by the pipe and/or fittings manufacturers shall only be applied on drysurfaces firstly over the whole spigot and then within the socket using a clean brush. It is prohibited to assemblesolvent cement joints whilst it is raining or under the temperatures limits as specified by the solvent cementmanufacturer;c)the spigot should be assembled promptly and the as
