Minimum cover for Class V RCP

Minimum cover for Class V RCP

Minimum cover for Class V RCP

(OP)
Hi,

What is the recommended minimum cover over Class V RCP? Where can it be found? Any help much appreciated.

RE: Minimum cover for Class V RCP

Cover requirements for RCP depend on the applied loading, quality of the bedding and, of course, the class of pipe. The American Concrete Pipe Association has prepared tables for highway loading. Here is the link to "LRFD Fill Height Table for Concrete Pipe":
http://www.concrete-pipe.org/pdf/FillHeightTables....

Note that Class V pipe that you are asking about is suitable for highway loading with only 1 foot of cover (the minimum shown in the tables) even if there is no bedding at all (Type 4 Installation). One foot is generally considered minimum cover for practical purposes. You did not state the loading for your application, but if it is higher than highway loading, you may need either more cover or a "Special Design" pipe.
