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.

Embodiment Construction

[0024] Such as figure 1 As shown, in the embodiment of the square-cylindrical corrugated pipe pile 1 of the present invention, the square-cylindrical pile body 11 is included, and the square-cylindrical pile body 11 is a prefabricated concrete part composed of a square and four semicircular arcs 12 , the inside is provided with a reinforcement cage (not shown in the figure).

[0025] The outer surface of each side of the square cylindrical pile body 11 is a nodular shape, forming a boss 14, so a plurality of bosses 14 are arranged on the outer surface of its four sides, which increases the pile side friction of the pipe pile.

[0026] The present invention also increases the pile end bearing capacity of the pipe pile due to the above-mentioned boss 14 being provided.

[0027] Further, connector structures (not shown in the figure) are respectively fixedly connected to the two ends of the square cylindrical pile body 11 . The connecting head structure is a steel structural me...
