Internal spiral steel pile
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.
本发明公开了一种内螺旋钢桩，包括开口桩身和螺旋叶片，桩身采用开口空心钢管，螺旋叶片设于桩身内壁，桩端为凹凸形或锯齿形。内螺旋钢桩桩身直径大，螺旋叶片焊接在桩身内壁，叶片与桩身中的土体相互咬合，在成桩受力时，由于桩身对土体的横向变形的限制，导致叶片压缩桩身中的土体难度增加，从而提高钢桩承载能力。本发明内螺旋钢桩在兼备传统螺旋钢桩优点的同时，内螺旋钢桩具有桩径大、承载力高、无需排土和运输方便的特点。
