3、on: 4b, Flexible and Metallic Pipe Release: Group 2 (June 2017) ASTM Designation: A761/A761M-04 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. Appropria
4、te 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 plate thickness of the pipe. Experience has shown that the successful performance of this product depends on the proper selection of plate thickness, type of bedding and backfill, manufacture in the plant, and care in the installation. The purchaser must correlate the above factor
6、s and also the corrosion and abrasion requirements of the field installation with the plate thickness. The structural design of corrugated steel structural plate pipe and the proper installation procedures are described in AASHTO LRFD Bridge Design Specifications, Section 12 and AASHTO LRFD Bridge C
7、onstruction Specifications, Section 26, respectively. 1.3. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each syst
8、em shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 2. REFERENCED DOCUMENTS 2.1.
