The ends of thepipe shall be normal to walls and center line of the pipe, withinthe limits of variations given in Section 15.C1417M 14129. Circumferential Reinforcement9.1 A line of circumferential reinforcement for any givento

The layers shall notbe separated by more than the thickness of one longitudinalplus 6 mm. The multiple layers shall be fastened together to
32、form a single cage. If the multiple layers of a cage containcircumferential splices, the individual layers shall be rotated sothat the splices are staggered. All other specificationrequirements, such as laps, welds, tolerances of placement inthe wall of the pipe, and so forth, shall apply to this me
33、thod offabricating a line of reinforcement. The design shall be basedon the centroid of the layers.9.2 Reinforcement placement and concrete cover shall con-form to the approved manufacturing data. The nominal con-crete cover over the circumferential reinforcement shall not beless than be 25 mm in pi
34、pe having a wall thickness of 63 mmor greater, and shall not be less than 19 mm in pipe having awall thickness of less than 63 mm. The location of thereinforcement shall be subject to the permissible variations indimensions given in Section 15. Requirements for placementand protective covering of th
35、e concrete from the inner or outersurface of the pipe do not apply to that portion of a cage thatis flared so as to extend into the bell or reduced in diameter soas to extend into the spigot.9.3 Where the wall reinforcement does not extend into thejoint area, the maximum longitudinal distance to the
36、 lastcircumferential from the inside shoulder of the bell or theshoulder of the spigot shall be 75 mm, except that if thisdistance exceeds one half of the wall thickness, the pipe wallshall contain at least a total reinforcement area of the minimumspecified area per linear metre times the laying len

43、specimens shall develop at least 50 % of theminimum specified tensile strength of the steel. For butt-welded splices in bars or wire, permitted only with helicallywound cages, pull tests of representative specimens shalldevelop at least 75 % of the minimum specified tensile strengthof the steel.10.4

46、ing of the longitudinals plus 25 mm, or Ld,where:Ld5 3.25Awrfys =flc(3)whichever is greater.10.4.3 At the option of the manufacturer, a more detailedanalysis may be made and the following exception to therequirements of 10.4.2 may be applied. If the area of circum-ferential reinforcement is at least
47、 twice that required forflexure, the first requirement of 10.4.2 shall not apply. Theoverlap measured between the outermost longitudinals on eachside of the splice shall be no less than that required by Eq 3,or25 mm, whichever is greater.10.4.4 Alternative splice designs that differ from 10.4 maybe
