Abstract

The invention discloses an internal spiral steel pile. The internal spiral steel pile comprises an open pile body and spiral blades, the pile body is an open hollow steel pipe, the spiral blades are arranged on the inner wall of the pile body, and a pile end is in a concave-convex shape or a sawtooth shape. The diameter of the pile body of the internal spiral steel pile is large, the spiral bladesare welded to the inner wall of the pile body, the blades are meshed with a soil body in the pile body, during pile forming stressing, due to the limitation of the pile body on transverse deformationof the soil body, the difficulty of compressing the soil body in the pile body by the blades is increased, and therefore the bearing capacity of the steel pile is improved. The internal spiral steelpile has the advantages of a traditional spiral steel pile and has the advantages of being large in pile diameter, high in bearing capacity, free of soil discharging and convenient to transport.

Description

technical field [0001] The invention relates to the technical field of spiral steel piles, in particular to an inner spiral steel pile. Background technique [0002] Aiming at the problems (1) When the pile diameter of the traditional spiral steel pile is large, the soil squeezing effect is obvious when the pile is sunk, and the pile is difficult to form; (2) The blades of the spiral steel piles are outside the pile body, and special measures need to be taken to prevent damage to the blades during transportation. Increased transportation difficulty and cost; Problem (3) the spiral steel pile will discharge soil during the drilling process, which is not conducive to environmental protection. Based on this, on the basis of retaining the advantages of traditional spiral steel piles, an internal spiral steel pile is proposed. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an internal spiral steel pil...
