Joints7.1 The joints shall be designed and the ends of the concrete pipe sections shall be formed so that the sections can be laidtogether to make a continuous line of pipe, compatible with the permissible variations given
29、in Section 15.8. Manufacture8.1 ConcreteThe aggregates shall be sized, graded, proportioned, and mixed with cementitious material and water andadmixtures, if any, to produce a homogeneous thoroughly mixed concrete mixture of such quality that the pipe will conform tothe design requirements of this s
30、pecification. The water-cementitious material ratio of all concrete shall be 0.53, or less, by weight.Minimum concrete strength shall be 27.6 MPa.8.2 FinishPipe shall be substantially free of fractures, large or deep cracks, and surface roughness. The ends of the pipe shallbe normal to walls and cen
31、ter line of the pipe, within the limits of variations given in Section 15.9. Circumferential Reinforcement9.1 A line of circumferential reinforcement for any given total area may be composed of up to two layers for pipe with wallthicknesses of less than 180 mm or three layers for pipe with wall thic
32、kness of 180 mm or greater. The layers shall not be separatedby more than the thickness of one longitudinal plus 6 mm. The multiple layers shall be fastened together to form a single cage.If the multiple layers of a cage contain circumferential splices, the individual layers shall be rotated so that
33、 the splices arestaggered. All other specification requirements, such as laps, welds, tolerances of placement in the wall of the pipe, and so forth,shall apply to this method of fabricating a line of reinforcement. The design shall be based on the centroid of the layers.9.2 Reinforcement placement a
34、nd concrete cover shall conform to the approved manufacturing data. The nominal concretecover over the circumferential reinforcement shall not be less than be 25 mm in pipe having a wall thickness of 63 mm or greater,and shall not be less than 19 mm in pipe having a wall thickness of less than 63 mm
35、. The location of the reinforcement shall besubject to the permissible variations in dimensions given in Section 15. Requirements for placement and protective covering ofthe concrete from the inner or outer surface of the pipe do not apply to that portion of a cage that is flared so as to extend int
36、othe bell or reduced in diameter so as to extend into the spigot.9.3 Where the wall reinforcement does not extend into the joint area, the maximum longitudinal distance to the lastcircumferential from the inside shoulder of the bell or the shoulder of the spigot shall be 75 mm, except that if this d
37、istance exceedsone half of the wall thickness, the pipe wall shall contain at least a total reinforcement area of the minimum specified area per linearmetre times the laying length of the pipe section. The minimum cover on the last circumferential near the spigot shoulder shallbe 13 mm.9.4 Where rei
38、nforcement is in the bell or spigot, the minimum end-cover on the last circumferential shall be 13 mm in the bellor 6 mm in the spigot.9.5 The continuity of the circumferential reinforcing steel shall be maintained during the manufacture of the pipe, except when,as agreed upon by the owner, lift eye
