1、Designation: C361 14Standard Specification forReinforced Concrete Low-Head Pressure Pipe1This standard is issued under the fixed designation C361; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification covers reinforced concrete pipe in-te

3、nded to be used for the construction of pressure pipelineswith low internal hydrostatic heads generally not exceeding125 ft.1.2 This specification is the inch-pound companion toSpecification C361; therefore, no SI equivalents are presentedin the specification.NOTE 1Field tests on completed portions

4、of the pipeline are notcovered by this specification for the manufacture of the pipe but should beincluded in specifications for pipe laying.2.

Designs are provided in Table 1for the above hydrostatic heads combined with external load-ings of 5, 10, 15, and 20 ft (designated A, B, C, and D in Table1)

18、of earth cover over the top of the pipe under specificinstallation conditions. The specific installation conditions arecovered in Appendix X1. Where the hydrostatic head, externalloadings, and installation conditions vary from those given inTable 1 and Appendix X1, detailed design calculations shall

19、 bemade. The design criteria for Table 1 are presented in Appen-dix X2.5. Basis of Acceptance5.1 Acceptability of the pipe in all diameters and classesshall be determined by the results of such material tests as arerequired in 6.2 through 6.9 by crushing tests on cured concretecylinders, by hydrosta

20、tic pressure tests on units of the pipe, byjoint leakage tests, and by inspection during or after manufac-ture to determine whether the pipe conforms to this specifica-tion as to design and freedom from defects.5.2 Age for AcceptancePipe shall be considered ready foracceptance when they conform to t
