Reinforced Circular Concrete Culvert, Storm Drain, Sewer Pipe, and Fittings
1.1 Pertains to reinforced circular concrete pipe and fittings intended to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts. Note: This Standard is applicable to manufacture and purchase only. 1.2 This Standard pertains to pipe that is intended to be used for jacking longitudinally in tunnel operations. Note: Such pipe may require special design to withstand the longitudinal loading anticipated and the purchaser should inform the manufacturer when pipes are to be so used. 1.3 This Standard establishes the following five strength classifications of reinforced concrete pipe and gives their physical and dimensional requirements: (a) 40 D; (b) 50 D; (c) 65 D; (d) 100 D; and (e) 140 D. 1.4 This Standard establishes the designated internal diameter as the diameter used to identify the pipe. 1.5 This Standard does not include requirements for bedding, backfill, or the relationship between field load conditions and the strength classification of the pipe. Note: Experience has shown that the successful performance of this product depends upon the proper selection of the strength classification of the pipe, the type of bedding and backfill, and care taken in the field construction work. The purchaser of the reinforced concrete pipe and jacking pipe specified herein is cautioned that the field requirements must be properly correlated with the strength classification of the pipe specified and adequate inspection at the construction site must be provided.
