A civil engineering building composite pile

Abstract

The present invention belongs to the field of combination piles, especially involving a kind of civil engineering building combination pile, including piles and support piles.There are multiple buffer springs between the buffer board and the fixed connection between the buffer board and the support pile. There is a partition of the sliding connection in the inserting pile, and the lower side of the partition is injected with water.There are multiple stretching springs in a fixed connection. The lower end of the buffer plate is fixed with a variable resistor, and a metal guide rod is fixed on the resistor.There is a adjustment mechanism that cooperates with the slide sheet on the partition.The present invention allows the combined pile to automatically regulate the resistance between itself and the soil according to the changes in temperature, to avoid the combination piles from being pulled up, affecting the stability of the overall structure.

Description

technical field [0001] The invention belongs to the field of composite piles, in particular to a composite pile for civil engineering construction. Background technique [0002] Civil engineering composite piles are an important part of the operation of housing construction sites. Engineering piles can be divided into friction piles, end bearing piles, end bearing friction piles and friction end bearing piles according to the relative ratio of lateral friction resistance and end resistance provided by soil. Four categories. [0003] The combined pile is generally inserted into the ground, but in autumn and winter, due to the drop in temperature, the moisture inside the soil is easy to freeze, the volume of water after freezing will increase, and the soil combined with water will freeze. When the soil expands under the action of ice water, the phenomenon of frost heaving of the soil layer is about to occur. This phenomenon is especially obvious in high latitude areas. When ...

AI Technical Summary

Problems solved by technology

[0003] Combination piles are generally inserted into the ground, but in autumn and winter, due to the drop in temperature, the moisture inside the soil is easy to freeze, and the volume of water after freezing will increase, and the soil combined with water will be frozen in time. When the soil expands under the action of ice water, the phenomenon of frost heaving of the soil layer will appear soon. This phenomenon is especially obvious in high latitude areas. When it is self-weight, the composite pile will be pulled up at this time, which will affect the stability of the composite pile support
