Example Embodiment
[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0033] As shown in the figure, the pipe burial structure that can reduce the vertical load on the top of the pipe in this embodiment includes a pipe trench 1 and a backfill trench 2 located above the pipe trench 1. The pipe trench 1 is provided with a pipe 3 and the surrounding filling 4 of the pipeline wrapped outside the pipeline, the side wall of the backfill trench 2 is a stepped wall with 3 steps, and the lowest step is located at the bottom of the backfill trench, and its lateral step surface 5 Higher than the top of the pipe, a layer of degradable material spacer 6 is disposed above the top of the pipe, and the degradable material spacer 6 is located below the lateral step surface 5 of the lowest step. Of course, in different embodiments, the side wall of the backfill trench 2 may also be a stepped wall with only one level of steps (such as figur...
