eter of the pipe. 5 to 0. 55 times, minimum thickness not less than 0. 6 M, maximum thickness not more than 1. 5 M. The sediment content in the gravel is not more than 5 %, the maximum particle size is not more than 50 mm, and the compaction is 85 % to 90 %. In order to prevent the cutoff, it is best to use coarse grained soil with a mud content of not more than 5 %, and the compaction is the same as that of the subgrade with the same depth.
