High-bearing-capacity foundation pile and method for processing same and foundation

Abstract

The invention relates to a high-bearing-capacity foundation pile and a method for processing the same and a foundation. The high-bearing-capacity foundation pile is composed of a pile head, a low-end pressure detector, a bottom pile body, an upper pile body and an upper-end pressure detector, the pile head is arranged on the end portion of the bottom pile body, the lower-end pressure detector contacting with the pile head is arranged on the lower end portion of the bottom pile body, the upper pile body is connected with the bottom pile body through a connecting disc, and the upper-end pressure detector is arranged on the upper portion of the upper pile body. The bottle pile body is designed to be of a multistage conical surface structure, so that stability of the bottom pile body is improved by injecting cement slurry; an end-portion pouring groove and a conical-surface pouring groove are arranged and filled with cement slurry, so that bearing capacity and friction force of the bottom pile body are improved; the upper pile body is designed to be of a multistage conical surface structure, so that the upper pile body is enabled to be high in stability, and anti-seismic performance of the upper pile body is improved; by arranging the lower-end pressure detector and the upper-end pressure detector, project quality is effectively controlled; the foundation pile is pressed into the foundation by adopting a mode of static-pressure pressing, so that working efficiency is improved.

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
