In other embodiments, the first socket 3 may be provided in a male configuration and the second socket 4 may be provided in a female configuration.
In order to facilitate the plug-in fixation, a groove is formed in the inner side wall 2 of the concave structure, a sliding block is arranged on the inner side wall 2 of the convex structure, and the position and the size of the groove and the sliding block are matched.
The filler in the filled region includes soil, rock, water, air, and magnetic material. Different combinations of fillers can be selected to be placed in the filling area according to different geological conditions, wherein the filling area of the space layer of the uppermost model is filled with soil.

Specifically, the side wall 2 of the convex structure is provided with a preformed hole 5, and the pipeline passes through the preformed hole 5.
