Sliding holes 12 are opened on the triangular embedded parts 11, and pull rods 13 are passed through the sliding holes 12. Locking nuts 14 are screwed on both ends of the pull rods 13 through external threads. A water suction pipe 15 is provided at the center of the square pile body 2, and the bottom end of the water suction pipe 15 is sleeved in the limiting pipe sleeve 6.
