Static pressure pipe pile with high bearing capacity

Abstract

The invention discloses a static pressure pipe pile with high bearing capacity, and relates to the technical field of bearing static pressure pipes, the static pressure pipe pile comprises a bearing static pressure column, the bearing static pressure column comprises a pressure-resistant pipe column body, the bottom of the pressure-resistant pipe column body is movably sleeved with a ground breaking conical head, and the outer surface of the top of the pressure-resistant pipe column body is coated with butt joint sealing soft rubber; a sleeve shell is arranged on the outer surface of the top of the butt joint sealing soft rubber, and a wear-resistant waterproof ferrule is arranged on the outer surface of the inner side of the top of the sleeve shell. An external water source is protected through the waterproof layer, corrosion of the water source is avoided, high-strength protection and compression resistance are achieved through extrusion of the high-compression-resistance layer on underground soil, internal friction is protected through the first wear-resisting layer, and the characteristics of protection and compression resistance on underground sports and the water source are achieved; the problem that an underground water source accelerates erosion of the tubular column is solved, and the effects of protecting underground movement and the water source and resisting pressure are achieved.

Description

technical field [0001] The invention relates to the technical field of bearing static pressure pipes, in particular to a static pressure pipe pile with high bearing capacity. Background technique [0002] Today's construction industry is developing rapidly, and there are more and more tall and ultra-high buildings. In terms of construction, high-strength concrete prestressed pipe piles are widely used. When encountering complex engineering geological conditions, the design of ordinary pipe piles cannot meet the application requirements. requirements, static pressure pipe pile construction has low noise, no pollution, no waste slurry, and a wide range of applications, especially suitable for construction in densely populated urban areas. There are following problems at prior art: [0003] 1. The existing static pressure pipe piles have technical problems such as complex structure, high cost, poor penetration rate, high damage rate, and low bearing capacity of single pile; ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a static pressure pipe pile with high bearing capacity, one purpose of which is to have the characteristics of increasing the penetration force of the pipe string, and solve the complex structure and poor penetration rate of the static pressure pipe pile with low bearing capacity of the single pile and so on; another purpose is to solve the problem that the number of impacts will be more, which will easily lead to cracks on the surface of the pipe string, thereby reducing the service life of the pipe string, so as to achieve that the static pressure pipe piles can Butt each other to increase the length and hardness
