Square cylindrical pipe pile and processing method thereof

Abstract

The invention discloses a square cylindrical pipe pile which at least comprises a square pile body; and a half-cylindrical outer surface is arranged on the outer surface on each side of the square pile body. The invention further discloses a processing method of the square cylindrical pipe pile. Due to the structural design of the half-cylindrical outer surfaces, the shape of the outer surface of the pipe pile is improved, the friction coefficient of the outer surface is increased and the pile side friction force of the pipe pile is improved. Simultaneously, due to the structural design of the half-cylindrical outer surfaces, the end area of the pipe pile is enlarged and the pile-end bearing capacity of the pipe pile is increased. Therefore, the square cylindrical pipe pile integrates the advantages of a circular pile and a square pile, simultaneously overcomes the inherent defects of the circular pile and the square pile, and has the characteristics of higher anti-compression friction force, higher anti-shearing performance, higher anti-pulling capacity, significant progress and beneficial effects.

Description

technical field [0001] The invention relates to the technical field of foundation piles, in particular to a square cylindrical 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. [0003] Wherein, the be...

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.
