Foundation pit prefabricated fender shock absorption pile and foundation pit retaining wall building method

Abstract

The invention discloses a foundation pit prefabricated fender shock absorption pile. The foundation pit prefabricated fender shock absorption pile comprises a pile body, the upper end surface of the pile body is provided with a liquid storage pool, and the bottom of the liquid storage pool is provided with a round hole vertically penetrating through the lower end surface of the pile body. Slurry is poured into a water isolation space formed by a cover plate and the wall of the liquid storage pool, the slurry achieves the effect of filtering shock on the earth surface, and a round pipeline achieves the isolation effect on shock transmission. The invention further discloses a foundation pit retaining wall building method. The foundation pit retaining wall building method comprises the following steps that a trench is dug section by section in the position where a foundation pit support structure plans to be built; foundation pit prefabricated fender shock absorption piles are lifted to the preset position one by one, and slurry in a space between two shock absorption piles is pumped; and slurry in the liquid storage pools and round pipelines of all the foundation pit prefabricated fender shock absorption piles is pumped one by one, shock absorption slurry is poured into the water isolation spaces, and construction of the foundation pit support structure is completed. Foundation pit support is conducted through the foundation pit prefabricated fender shock absorption piles, the construction quality of the foundation pit support structure can be ensured, and an obvious shock absorption and isolation effect on the inner structure of a foundation pit is achieved.

Description

technical field [0001] The invention relates to the technical field of shock absorption for underground engineering, in particular to a foundation pit prefabricated enclosure shock-absorbing pile which has the effect of shock absorption and isolation in foundation pit engineering. [0002] The invention also relates to a method for constructing the retaining wall of the foundation pit. Background technique [0003] In recent years, with the rapid development of urban underground engineering and the increasingly complex construction environment, more and more attention has been paid to the anti-seismic and shock-absorbing problems of underground structures. Urban underground engineering may be affected by various dynamic effects such as earthquakes, blasting construction, and vehicle loads, and damage or even destruction will inevitably occur. [0004] The traditional anti-shock isolation measures mainly include setting up anti-seismic trenches for seismic isolation, and als...

Problems solved by technology

However, some of these traditional shock absorption and isolation methods have no obvious effect, and some have high cost and high labor intensity, which have a great impact on the environment.

[0005] Therefore, in the foundation pit engineering, there has been a lack of shock-absorbing and isolation methods with ideal effect, good economy, little impact on the environment, and low labor intensity.
