Embodiment Construction
[0011] Such as figure 1 As shown, the present invention discloses a self-compacting spiral steel pile, comprising a pile body 1 and a helical blade 2, the helical blade 2 is arranged on the outer wall of the front end of the pile body 1, and the diameter of the pile body above the helical blade 2 is enlarged .
[0012] The diameter of the pile body 1 at the position above the helical blade 2 is greater than or equal to the outer diameter of the helical blade 2 .
[0013] The head of the spiral steel pile is conical, and the spiral blade 2 is located above the conical shape.
[0014] The helical blade 2 is a spiral wound on the outer wall of the pile body.
[0015] The main feature of the self-compacting spiral steel pile of the present invention is that the pile diameter at the position above the spiral blade of the spiral steel pile is enlarged, and the pile diameter can be greater than or equal to the outer diameter of the spiral blade.
[0016] Finally, it should be note...
