Foundation pile with high bearing capacity and its treatment method with foundation

Abstract

The invention relates to a foundation pile with high bearing capacity for building foundation treatment and a treatment method for the foundation. It is composed of a pile head, a lower end pressure detector, a bottom pile body, an upper pile body, and an upper end pressure detector. There is a pile head at the end, and a lower end pressure detector in contact with the pile head is provided at the lower end of the bottom pile body; Detector; because the bottom pile body is designed as a multi-level conical surface structure, the stability of the pile body is improved by injecting cement slurry; because there are end irrigation grooves and conical surface irrigation grooves, cement slurry is injected, increasing the The bearing capacity and friction of the pile body; because the upper pile body is designed as a multi-level conical surface structure, the stability of the pile body is good, and the seismic performance of the pile body is improved; because the lower and upper end pressure detectors are installed, the project quality is improved. Effective control; the foundation pile is pressed into the foundation by static pressure pressing, which improves the work efficiency.

Description

technical field [0001] The invention relates to a foundation device in the foundation treatment of buildings in the construction industry, in particular to a foundation pile with high bearing capacity and a treatment method for the foundation. Background technique [0002] After retrieving relevant patent documents, no high-bearing-capacity foundation pile with the same structure as the present invention and its treatment method with the foundation have not yet been retrieved. Existing building industry generally adopts concrete buried pile and concrete prefabricated pile to come as foundation device in high-rise building foundation construction process. Concrete buried piles have been phased out due to the long construction time on site. With the development of science and technology, prefabricated piles are used as foundation piles, and the method of pressing foundation piles into the foundation has been widely used. However, due to the poor bearing capacity of the soil i...

Problems solved by technology

With the development of science and technology, prefabricated piles are used as foundation piles, and the method of pressing foundation piles into the foundation has been widely used. However, due to the poor bearing capacity of the soil in many places, it cannot meet the actual requirements and cannot solve the bearing problem. It is often found that the settlement of prefabricated piles is greater than the design range, which makes the use of prefabricated piles abandoned in engineering and changed to other design schemes. This is mainly because it is sometimes difficult to find the corresponding pile foundation within a certain depth during the construction of prefabricated piles. bearing layer, or due to insufficient frictional resistance, the selection and construction of prefabricated piles are abandoned, and during the construction process, when one pile is pressed in, other piles are pressed in the adjacent area again, because of the The extrusion damage of the root pile will cause the damage of the pile foundation to produce gaps, which will affect the effect of the pile foundation

In order to increase the end surface resistance and frictional resistance, sometimes it is only possible to increase the diameter and length of the pile to increase the end surface resistance and frictional resistance. In fact, such construction brings about the increase in the length and diameter of the tubular pile. The increase will significantly increase the cost of the project, so it is necessary to improve the existing foundation piles to achieve the effect of improving project quality and reducing costs
