[0034] In a specific embodiment of the present invention, see Figures 1 - 3 , the support plate 11, the first bearing plate 12, and the second bearing plate 13 are all arc-shaped plates.

[0035] Setting the support plate 11, the first bearing plate 12, and the second bearing plate 13 as arc-shaped has a stronger bearing capacity and a better support effect.

[0038] At this time, the first bearing plate 12 and the second bearing plate 13 disperse the vertical pressure received by the top support structure 2, ensuring that the top support structure does not deform, effectively improving the supporting force of the top support structure, thereby extending its service life and improving its ability to protect underground pipelines.

[0039] In a specific embodiment of the present invention, see Figures 1 - 3 , the circle made with the distance from the tangent point of the circles where the first bearing plate 12 and the second bearing plate 13 are located to the vertex of the circle where the top connection structure 2 is located as the diameter is the circle where the support plate is located;

[0040] The support plate 11 at the bottom is set to be arc-shaped, and a circle is made with the above diameter, and its bottom can better cooperate with the groove for burying pipelines, making the installation more convenient and being able to provide effective support for the first bearing plate 12 and the second bearing plate 13.

[0041] In a specific embodiment of the present invention, see Figures 1 - 3 , a first limiting groove 211 and a second limiting groove 212 are symmetrically arranged at the bottom of the first connection body 21, the first bearing plate 12 cooperates with the first limiting groove 211, and the second bearing plate 13 cooperates with the second limiting groove 212;
