Square cylindrical corrugated tube pile and processing method thereof

Abstract

The invention discloses a square cylindrical corrugated tube pile which at least comprises a square cylindrical pile body. The outer surface of each edge of the square cylindrical pile body is of a corrugated shape. The invention also discloses a processing method of the square cylindrical corrugated tube pile. For the square cylindrical corrugated tube pile disclosed by the invention, due to the structure design of the corrugated outer surface, the shape of the outer surface of the tube pile is improved, the friction coefficient of the outer surface is increased, and the pile-side friction of the tube pile is improved. Meanwhile, due to the structure design of the corrugated outer surface, the end area of the tube pile is increased and the pile end bearing capacity of the tube pile is improved. Therefore, the square cylindrical corrugated tube pile disclosed by the invention combines the advantages of a round pile and a square pile, the respective inherent defects of the round pile and the square pile are also overcome, and the square cylindrical corrugated tube pile has higher compression resistance friction, higher shear resistance and higher pull-out resistance capability and has obvious progressive and beneficial effects.

Description

technical field [0001] The invention relates to the technical field of foundation piles, in particular to a square cylindrical corrugated pipe pile used as a building foundation. The invention also relates to a processing method of the pipe pile. Background technique [0002] For the construction of a high-rise building, its structural safety depends to a large extent on the foundation design, and the foundation design is carried out in accordance with the design specifications based on geological survey parameters. When building various buildings in areas with poor soil quality, especially high-rise buildings, heavy factory buildings and structures with special requirements, foundation pile technology has become a widely used foundation form. The foundation pile technology mainly uses mechanical equipment such as a static pile driver to drive multiple prefabricated pipe piles into the ground according to the designed layout as the foundation of the building.

Problems solved by technology

But its disadvantage is that the pile side friction coefficient is small, and the pile side friction of the square pile is mainly concentrated at the four corners, so the overall pile side friction force is small

[0007] In this case, the existing foundation pile technology must adopt additional technical means to perform a technical treatment on the unfavorable geological layer under the surface to meet the requirements of becoming a bearing layer, or increase the number of foundation piles, otherwise it will not be able to meet the load bearing requirements at the same time.
