Bedding and backfill requirements are outlined in ASTM D2321 (Standard Practice for Underground Installation of Thermoplastic Pipe for Sewers and Other Gravity-Flow Applications), which is often included in the engineer’s specification for installation. Two amendments to this part of the standard have so far been published, which have PE pipes to be minimum PE100 PN16. (b) Fibre-Reinforced Concrete (FRC) Rigid Pipes Any FRC rigid pipes that have cracks wider than 0.1 mm or are damaged prior to laying and backfilling shall be rejected. Where the trench is to be backfilled, this shall be done in accordance with the provisions of Clause 701.15 and the final surface shall be shaped to conform with the adjoining profile. If you look at the Oil Exploration platform, Refinery and Petrochemical complex one thing that catches the attention is a complex network of piping.

The top sections shall be matched to the bottom sections and shall not be lapped over adjoining bottom sections. Clay pipes are prone to impact damage from such things as large stones or a half brick coming into contact with the pipe during the back fill process, settlement to the sub-soil beneath the pipe can lead to stress fractures and collapse it is therefore necessary to ensure that the pipe work is bedded an an appropriate granular material. The ITD pipe specification policy is intended to identify all compliant pipe materials, trench bedding, manholes, and headwalls and inlet options. No-Dig Repairs In fact when working in pure sand particularly beneath the highways and roads it does go against the grain to be removing all the spoil from site and import tonnes of M.O.T and granular fill to back fill the trench. Damaged sections of pipe may be cut out and the remaining pipe installed. The concrete extends upwards on each side of the pipe for a height equal to but not less than 1/4 of the pipe diameter … Except where the pavement under which the culvert passes is to be abandoned, the trench shall be kept to the minimum width to allow removal of the culvert or laying a replacement. The type of granular bedding used will dependant on your location, typically a single sized pea gravel would be used, however there is a definite push towards a more environmentally friendly form of bedding materials such as recycled glass and slate aggregates that are the bye-product of other industries. If however you are installing a hundred metres of new pipe work the cost of importing the additional granular bedding and then removing the excess spoil from site may well make it worth your while to use the selected back fill as shown above. Unless specified otherwise the tolerance on location of pipes compared to the design or a change to the design notified in accordance with this clause shall be: (a) offset of entry pits required to match lines of kerbs or barriers ±20 mm (b) plan location of pits other than offsets to kerb lines or barriers ±100 mm (c) invert level of pipes at pits ±50 mm (d) departure from design grade of pipe runs ±10 mm in 10 m provided minimum grade is not less than 1:250 The location of each run of underground drainage shall be verified by a survey certificate prior to backfilling the culverts and shall be recorded progressively on the Contractor’s asconstructed drawings. For pressure pipe, the trench bottom may undulate, but must support the pipe smoothly and be free of ridges, hollows, and lumps. Bedding materials for pipes BS EN 124 BS EN 1610, The specification of clay pipes to BS EN 295 1-7 BS EN 295 Part 1 specifies the requirements for appropriate dimensions, tolerances and performance of flexibly jointed pipes, fittings and joints for drains and sewers.
