3、ision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers corrugated steel structural plate, zinc-coated, used in the construction of pipe, pipe-arches, arches,underpasses, and special shapes for field assembly. Approp

4、riate fasteners and accessory materials are also described. The pipe,arches, and other shapes are generally used for drainage purposes, pedestrian and vehicular underpasses, and utility tunnels.1.2 This specification does not include requirements for bedding, backfill, or the relationship between ea

5、rth cover load and platethickness of the pipe. Experience has shown that the successful performance of this product depends upon the proper selection ofplate thickness, type of bedding and backfill, manufacture in the plant, and care in the installation. The purchaser must correlatethe preceding fac

6、tors and also the corrosion and abrasion requirements of the field installation with the plate thickness. Thestructural design of corrugated steel structural plate pipe and the proper installation procedures are described in PracticesA796/A796M and A807/A807M.1.3 This specification is applicable to

7、orders in either inch-pound units (as A761) or SI units (as A761M). The values stated ineither SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exactequivalents; therefore, each system shall be used independently of the other. Combin

8、ing values from the two systems may resultin non-conformance with the standard. Inch-pound units and SI units are not necessarily equivalent. SI units are shown in bracketsin the text, but they are the applicable values when the material is ordered to A761M.1.4 This specification references notes an
