suffer any undue structural strain, any damage due to fall or impact. The arrangement may be got approved by the Engineer. Similarly, the arrangement for lowering the pipe in the bed shall be got approved by the Engineer. It may be with tripod-pulley arrangement or simply by manual labour in a manner that the pipe is placed in the proper position without damage. The laying of pipes on the prepared foundation shall start from the outlet and proceed towards the inlet and be completed to the specified lines and grades. In case of use of pipes with bell-mouth, the belled end shall face upstream. The pipes shall be fitted and matched so that when laid in work, (hey form a culvert with a smooth uniform invert. Any pipe found defective or damaged during laying shall be removed at the cost of the Contractor. 2906. JOINTING The pipes shall be jointed either by collar joint or by flush joint. In the former case, the collars shall be of RCC 150 to 200 mm wide and having the same strength as the pipes to be jointed. Caulking space shall be between 13 and 20 ram according to the diameter of the pipe. Caulking material shall be slightly wet mix of cement and sand in the ratio of 1:2 rammed with caulking irons. Before caulking, the collar shall be so placed that its centre coincides with the joint and an even annular space is left between the collar and the pipe. Flush joint may be internal flush joint or external flush joint. In either case, the ends of the pipes shall be specially shaped to form a self centering joint with a jointing space 13 mm wide. The jointing space shall be filled with cement mortar, 1 cement to 2 sand, mixed sufficiently dry to remain in position when forced with a trowel or rammer. Care shall be taken to fill all voids and excess mortar shall be removed. For jointing pipe lines under light hydraulic pressure, the recess at the end of the pipe shall be filled with jute braiding dipped in hot bitumen or other suitable approved compound. Pipes shall be so jointed that the bitumen ring of one pipe shall set into the recess of the next pipe. The ring shall be thoroughly compressed by jacking or by any other suitable method. All joints shall be made with care so that their interior surface is smooth and consistent with the interior surface of the pipes. After finishing, the joint shall be kept covered and damp for at least four days. 2907. BACKFILLING Trenches shall be backfilled immediately after the pipes have been laid and the jointing material has hardened. The backfill soil shall be clean, free from boulders, large roots, excessive amounts of sods or other vegetable matter, and lumps and shall be approved by the Engineer. Backfilling upto 300 mm above the top of the pipe shall be carefully done and the soil thoroughly rammed, tamped or vibrated in layers not exceeding 150 mm, particular care being taken to thoroughly consolidate the materials under the haunches of the pipe. Approved pneumatic or light mechanical tamping equipment can be used. Filling of the trench shall be carried out simultaneously on both sides of the pipe in such a manner that unequal pressures do not occur. In case of high embankment, after filling the trench upto the top of the pipe in the above said manner, a loose fill of a depth equal to external diameter of the pipe shall be placed over the pipe before further layers are added and compacted. 2908. HEADWALLS AND OTHER ANCILLARY WORKS Headwalls, wing walls, aprons and other ancillary works shall be constructed in accordance with the details shown on the drawings or as directed by the Engineer, Masonry for the walls shall conform to Section 1300,1400 or 1700 as applicable. Aprons shall conform to Section 2500. 2909. OPENING TO TRAFFIC No traffic shall be permitted to cross the pipe line unless height of filling above the top of the pipe line is atleast 600 mm. 2910. MEASUREMENTS FOR PAYMENT
R.C.C. pipe culverts shall be measured along their centre between the inlet and outlet ends in linear metres. Selected granular material and cement concrete for pipe bedding shall be measured as laid in cubic metres. Ancillary works like headways, etc., shall be measured as provided for under the respective Sections. 2911. RATE The Contract unit rate for the pipes shall include the cost of pipes including loading, unloading, hauling, handling, storing, laying in position and jointing complete and all incidental costs to complete the work as per these <strong>Specification</strong>s. Ancillary works such as excavation including backfilling, concrete and masonry shall be paid for separately, as provided under the respective Clauses.
