Civil engineering building composite pile

Abstract

The invention belongs to the field of composite piles, and particularly relates to a civil engineering building composite pile. The pile comprises an insertion pile and a supporting pile, the insertion pile is in hollow design, the supporting pile is slidably arranged in the insertion pile, a buffer plate is fixedly connected in the insertion pile, and a plurality of buffer springs are fixedly connected between the buffer plate and the supporting pile. A partition plate is slidably connected into the insertion pile, water is injected into the lower side of the partition plate, a plurality of extension springs are fixedly connected between the buffer plate and the partition plate, a rheostat is fixedly connected to the lower end of the buffer plate, a metal guide rod is fixedly connected to the rheostat, a sliding piece is slidably connected to the metal guide rod, and the sliding piece is in contact connection with the rheostat. The partition plate is provided with an adjusting mechanism matched with the sliding piece. The composite pile can automatically regulate and control the resistance between the composite pile and soil according to the change of the air temperature, and the situation that the composite pile is pulled up, and the stability of the whole structure is affected is avoided.

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 side friction resistance and end resistance provided by the soil. Four categories. [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 latitu...

[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
