The invention discloses a pipe burying structure capable of reducing pipe top vertical loads and a construction method for the pipe burying structure. The construction method comprises the steps of S1, digging a pipe groove and a backfill groove above the pipe groove and digging at least one step on two side walls of the backfill groove; S2, laying pipes in the pipe groove and completing port welding of the pipes; S3, filling earth in the pipe groove, and compacting and flattening the filled earth to the pipe top elevation; S4, laying a degradable material interlayer above the top of the pipe, wherein the degradable material interlayer is disposed below a transverse step plane of the lowest layer of steps; S5, filling earth into the backfill groove and compacting the earth. According to the pipe burying structure and the construction method for the pipe burying structure, an soil arch effect and backfill groove side wall friction can be used for obviously reducing the top pressure of the pipes, and the pipes are protected from being fractured and damaged. The construction process is simple, costs of used materials are low, and the construction method has a good application prospect and a wide generalization performance and applicable to open digging burying of underground shallow buried pipes.
