Code for Outdoor Drainage Design (GB 50014 2006) The minimum covering depth of the pipe top should be determined according to the strength of the pipe, external load, soil freezing depth and soil properties, combined with local buried pipe experience. The minimum covering depth of the top of the pipe should be: under the sidewalk and under the roadway.

In general, drainage pipes should be buried below the freezing line. When the area or the area with similar conditions has shallow burial experience or takes corresponding measures, it can also be buried above the freezing line, and its shallow burial value should be determined according to the experience of the area, but the safe operation of the drainage pipeline should be ensured!
