Square-prism-reinforced pipe pile and machining method thereof

Abstract

The invention discloses a square-prism-reinforced pipe pile, which at least comprises a square pile body. A prismatic outer surface is arranged on the outer surface at each side of the square pile body, and a reinforcing rib is also arranged on the outer surface of the square pile body. Furthermore, the invention discloses a machining method of the square-prism-reinforced pipe pile. Due to the structural designs of the prismatic outer surface and the reinforcing rib, the square-prism-reinforced pipe pile provided by the invention is improved in outer surface shape, increased in friction coefficient of the outer surface and enhanced in pile-side friction force. Simultaneously, due to the structural designs of the prismatic outer surface and the reinforcing rib, the square-prism-reinforced pipe pile is also increased in end area and improved in pile-end bearing capacity. Therefore, the square-prism-reinforced pipe pile provided by the invention has the advantages of a round pile and a square pile, simultaneously also overcomes the respective inherent disadvantages of the round pile and the square pile and is higher in pressure-resistant friction force, higher in shear performance, higher in pullout resistance, and obvious in improvement and beneficial effect.

Description

technical field [0001] The invention relates to the technical field of foundation piles, in particular to a square rib reinforced 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...

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.
