1、Designation: C506 16bStandard Specification forReinforced Concrete Arch Culvert, Storm Drain, and SewerPipe1This standard is issued under the fixed designation C506; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number 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
3、arch-shaped con-crete pipe to be used for the conveyance of sewage, industrialwastes, storm water, and for the construction of culverts.1.2 This specification is the inch-pound companion toC506M; therefore, no SI equivalents are presented in thespecification. Reinforced concrete pipe that conform to
4、 therequirements of C506M are acceptable under this SpecificationC506 unless prohibited by the owner.NOTE 1This specification is a manufacturing and purchase specifica-tion only, and does not include requirements for bedding, backfill, or therelationship between field load condition and the strength
5、 classification ofpipe. However, experience has shown that the successful performance ofthis product depends upon the proper selection of the class of pipe, typeof bedding and backfill, and care that the installation conforms to theconstruction specifications. The owner of the reinforced concrete pi
6、pespecified herein is cautioned that he must correlate the field requirementswith the class of pipe specified and provide inspection at the constructionsite.2.
