Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] As shown in the figure, this embodiment can reduce the pipeline embedding structure of the vertical load on the top of the pipeline, including a pipeline trench 1 and a backfill soil trench 2 above the pipeline trench 1, and the pipeline trench 1 is provided with a pipeline 3 and the surrounding filling soil 4 of the pipeline wrapped outside the pipeline, the side wall of the backfill soil trench 2 is a stepped wall with 3 steps, the lowest step is located at the bottom of the backfill soil trench, and its transverse step surface 5 Higher than the top of the pipe, a layer of degradable material interlayer 6 is arranged above the top of the pipe, and the degradable material interlayer 6 is located below the transverse step surface 5 of the lowest step. Of course in different implementations, the side wall of the backfill trench 2 can also be a ste...
