16.3.3 Failure to remove the ridge will result in cement in the fitting or socket beingscraped away from the jointing surfaces, leading to a dry joint with probability ofjoint failure.16.3.4 Remove all burrs and ridges with a debarring knife, file, or abrasive paper.16.3.5 A chamfer prevents the cement film from being wiped off into the interior of thesocket during assembly. Pipe and must be chamfered at an angle of 15 degreewith a file, To provide and approximately 2mm wide, 15 0 chamfer on pipe ends.16.4 Cutting of asbestos cement pressure pipe16.4.1 The pipe should be rigidly held on two parallel rafters nailed to cross beams,taking care that the portion to be cut does not overhang and the cut mark isbetween the two rafters.16.4.2 The pipes should be neatly cut at the chalk mark with carpenter -saw having a long blade, by slowly rotating the pipe around its longitudinal axisso as to have the uncut portion on top for cutting.16.4.3 Cutting of the pipe at the overhang should as for as possible be avoided, it isdangerous as an overhanging end is liable to tear off due to its weight beforethe cut is completed.16.4.4 Cut should always be perpendicular/at right angle to the axis of the pipe.16.5 Cutting of Ductile iron pipes16.5.1 The cutting of ductile iron pipe should be done in such a manner so that nodamage is caused to the pipe/cement lining and cut surfaces of the pipe issmooth and perpendicular (at right angles) to the axis of the pipe.16.5.2 This could be done either by use of chisel or by other suitable mechanicalmeans.16.6 Cutting of Glazed stoneware pipes16.6.1 The cutting of pipe for inserting, fitting or closure pieces shall be done in a neatand workmanlike manner without damage to the pipe or glazing so as to leavea smooth end at right angles to the axis of the pipe16.7 Manufacture of Mild Steel Plate Specials :16.7.1 During the course of execution, it sometimes becomes necessary to provide anon-standard special to fit into the pipeline. This can be conveniently made outof steel plates. An item to cover such emergency is also provided for in theschedule. Similarly, item to provide a mild steel flange has also beenintroduced to cover the specific requirement during execution.Urban Administration & Development Department Page 198
16.7.2 An item for laying and jointing steel pipes, incorporating field welding has alsobeen introduced to cover the special requirements during execution.16.8 All materials shall conform to relevant ISS.16.9 Cast Iron Manhole Covers and Frames16.9.1 When cast iron manhole covers and frames are used they shall confirm to IS1726 (parts 1 to 7). The frames of manhole shall be firmly embedded to correctalignment and level in plain concrete on the top of masonry. After completion ofthe work, manhole covers shall be sealed by means of thick grease. Provisionfor providing and fixing including labour and material has been made.16.9.2 Manhole covers and frame shall be manufactured from appropriate grade ofgrey cast iron not inferior than FG 150 grade of IS 210.16.9.3 They shall be cleanly cast and shall be free from air and sand holes, cold shutsand warping.16.9.4 Covers shall have on its operative top a raised chequered design to provide foran adequate no-slip grip. The rise of chequres shall be not less than 4 mm.16.9.5 Key holes, Keys and lifting devices shall be provided in the manhole covered tofacilitate their placement in the frames and their operative maintenance.16.9.6 Manhole covers and frames shall be coated with material having base with ablack bituminous composition. The coating shall be smooth and tenacious. Itshall not flow when exposed to temperature of 63 0 C and shall not be so brittleas to chip off at temperature of 0 0 C.16.9.7 Size and shape and performance requirement of manhole covers and framesshall conform to IS 1726.16.9.8 Each manhole covers and frame shall have cast on them the followinginformation:(a) Manufacturer's name or trade-mark.(b) Grade designation(c)(d)(e)Date of manufacturerThe words SWD or 'Sewer' to denote 'storm water drain' or 'sewer'respectively.Identification marks as required by Engineer-in-Charge.16.9.9 The cover shall be gas tight and water tight.16.9.10 The sizes of covers specified shall be taken as the clear internal dimensions ofthe frame.16.9.11 The approximate weight of the various type of manhole covers and framesshall be as per IS 1726.Urban Administration & Development Department Page 199
