Engineering pipe pile foundation

Abstract

The invention discloses an engineering pipe pile foundation, and belongs to the field of building construction. According to the technical scheme, the foundation comprises a fixed net, a fixed devicefixedly arranged in the fixed net, a prefabricated pile fixed into the fixed device and a stress device arranged on the prefabricated pile. The fixed net is composed of a frame and cross beams, the cross beams have the longitudinal cross beam and the transverse cross beam, the longitudinal cross beam and the transverse cross beam are crossed, the stress device comprises a stress cylinder arrangedat the upper end of the prefabricated pile in a sleeving manner and a ring fixed to the lower end of the stress cylinder, the inner ring of the ring is attached to the outer surface of the prefabricated pile, and multiple guide piles are evenly fixed to the lower surface of the ring. The problem that the pipe pile foundation is prone to knowing down is solved, and the effect of preventing the pipepile foundation from toppling and breaking is achieved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an engineering pipe pile foundation. Background technique [0002] Pile foundation is a foundation form with high bearing capacity, wide application range and long history. With the improvement of production level and the development of science and technology, the type, technology, design theory, calculation method and application range of pile foundation have been greatly developed, and are widely used in high-rise buildings, ports, bridges and other projects; It is a force-transmitting member that transfers all or part of the load of the building to the foundation soil and has a certain stiffness and bending resistance. Its cross-sectional size is much smaller than its length. The pile foundation is composed of multiple piles buried in the foundation (called pile groups) and pile platforms (called caps) that combine the pile groups to work together; the function of the pil...

AI Technical Summary

Problems solved by technology

[0004] When the pipe pile foundation is applied, a plurality of pipe piles will be driven into the ground with a pile driver in a certain area of ​​the earth, and when driving the pipe piles, they will be driven into the ground one by one, because when the pipe piles are driven When the pile is piled, the pipe pile will cause the soil layer of the earth to move laterally, and then the moving soil layer will cause an impact on the pipe pile that has been driven into the ground, causing the pipe pile to fall or even break the pile, and the pipe pile needs to be driven out and restarted Intrusion requires repeated construction, resulting in reduced construction efficiency
