When splicing, the large holes formed by the supporting feet 14 between adjacent supporting piles 1 can be filled with fillers such as crushed stone, fine stone concrete, and soil, or can be left unfilled as a fish nest. Mortar is poured into the small holes formed by the first interface 17 and the second interface 18 of the adjacent supporting piles 1 to prevent soil leakage. When there are special water-stopping requirements, concrete is poured into the large holes.

The steel skeleton 2 includes a transverse rib 21, a first hook rib 22, a longitudinal rib 23, a transverse stirrup 24, a second hook rib 25, an oblique rib 26 and a reinforcing rib 27.

[0049] Specifically, the upper end of the oblique rib 26 can be fixed at the midpoint of the crossbeam 11 .

[0050] Furthermore, the lower end of the oblique reinforcement 26 may be fixed at the intersection of the longitudinal reinforcement 23 and the transverse stirrup 24 .

[0051] In summary, the utility model improves the bending and shearing resistance by increasing the length of the bending section, and further adds oblique reinforcement to form a triangular structure with the transverse reinforcement to increase stability; at the same time, the bottom of the support pile is an arch structure, which evenly transfers the gravity load to the support point, and has better load-bearing performance.
