Joints7.1 The joints shall be designed and the ends of the concretepipe sections shall be formed so that the sections can be laidtogether to make a continuous line of pipe, compatible with thepermissible variations give

27、n in Section 15.8. Manufacture8.1 ConcreteThe aggregates shall be sized, graded, pro-portioned, and mixed with cementitious material and water andadmixtures, if any, to produce a homogeneous concrete mixtureof such quality that the pipe will conform to the designrequirements of this specification. T

28、he water-cementitiousmaterial ratio of all concrete shall be 0.53, or less, by weight.Minimum concrete strength shall be 4000 psi.8.2 FinishPipe shall be substantially free of fractures,large or deep cracks, and surface roughness. The ends of thepipe shall be normal to walls and center line of the p

29、ipe, withinthe limits of variations given in Section 15.9. Circumferential Reinforcement9.1 A line of circumferential reinforcement for any giventotal area may be composed of up to two layers for pipe withwall thicknesses of less than 7 in. or three layers for pipe withwall thickness of 7 in. or gre

30、ater. The layers shall not beseparated by more than the thickness of one longitudinal plus14 in. The multiple layers shall be fastened together to form asingle cage. If the multiple layers of a cage contain circumfer-ential splices, the individual layers shall be rotated so that thesplices are stagg

31、ered.All other specification requirements, suchas laps, welds, tolerances of placement in the wall of the pipe,and so forth, shall apply to this method of fabricating a line ofreinforcement. The design shall be based on the centroid of thelayers.9.2 Reinforcement placement and concrete cover shall c

32、on-form to the approved manufacturing data. The nominal con-crete cover over the circumferential reinforcement shall not beless than 1 in. in pipe having a wall thickness of 212 in. orgreater, and shall not be less than34 in. in pipe having a wallC1417 112thickness of less than 212 in. The location

33、of the reinforcementshall be subject to the permissible variations in dimensionsgiven in Section 15. Requirements for placement and protec-tive covering of the concrete from the inner or outer surface ofthe pipe do not apply to that portion of a cage that is flared soas to extend into the bell or re

34、duced in diameter so as to extendinto the spigot.9.3 Where the wall reinforcement does not extend into thejoint area, the maximum longitudinal distance to the lastcircumferential from the inside shoulder of the bell or theshoulder of the spigot shall be 3 in., except that if this distanceexceeds one

35、 half of the wall thickness, the pipe wall shallcontain at least a total reinforcement area of the minimumspecified area per linear foot times the laying length of the pipesection. The minimum cover on the last circumferential nearthe spigot shoulder shall be12 in.9.4 Where reinforcement is in the b

36、ell or spigot, theminimum end-cover on the last circumferential shall be12 in.in the bell or14 in. in the spigot.9.5 The continuity of the circumferential reinforcing steelshall be maintained during the manufacture of the pipe, exceptwhen, as agreed upon by the owner, lift eyes or holes areprovided

38、 the maximumflexural stress.10.1.2 When pipe are marked to show a specific orientationin the ground, any weld to, or splice of, a circumferential shallbe considered to be at a distance determined by the orientationangle closer to the point of maximum flexural stress than themarking indicates.10.1.3

For butt splices of circumferentials or

43、wherewelds are made to circumferentials, pull tests, Pt, of represen-tative specimens of the circumferential across the finished weldshall demonstrate a strength of no less than:Pt5 1.1 Awrfy(1)or no less than:Pt5 0.5 Awafy(2)whichever is greater.10.4 Lapped Splices of Circumferential Reinforcement:

44、10.4.1 Where lapped circumferentials are spliced by weld-ing, they shall be lapped no less than 2 in. Pull tests ofrepresentative specimens shall develop no less than 0.9 timesdesign yield strength of the circumferential.10.4.2 At the option of the manufacturer, a more detailedanalysis may be made a

If the area of circum-ferential reinforcement is at least twice that required forflexure, the first requirement of 10.4.5 shall not apply. Theoverlap measured between the outermost longitudinals on eachside of the splice shall be no less than that required by Eq 6, or1 in., whichever is greater.10.4.7 Alternative splice designs t
