Deep foundation pit integral structure for building construction and construction method thereof

Abstract

The invention discloses a deep foundation pit integral structure for building construction and a construction method thereof. The deep foundation pit integral structure comprises a plurality of vertical piles fixedly arranged around the inner wall of a deep foundation pit, wherein a spiral stair which is spirally upward is fixedly arranged in the deep foundation pit, a plurality of water pumping pipelines are fixedly connected to the inner side of the spiral stair, a water pumping opening is formed in the lower part of any one of the water pumping pipelines, cleaning outlets are formed in the upper parts of the joints of the water pumping pipelines and the spiral stair, and an adjusting mechanism comprises a rotating shaft and an adjusting baffle. According to the deep foundation pit integral structure, in the using process, the spiral stair is arranged so that workers can conveniently enter and exit from the deep foundation pit, accumulated water in the deep foundation pit is pumped out through the water pumping pipelines so that the internal structure of the deep foundation pit can be prevented from being corroded by the accumulated water for a long time, moreover, the water outlet at each cleaning outlet is independently adjusted through the adjusting mechanism, so that the cleaning strength of the spiral stair is guaranteed, meanwhile, the water is saved, and the situation that the water is accumulated due to the fact that too much cleaning water is accumulated at the bottom of the deep foundation pit again is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction foundation pits, in particular to an overall structure of deep foundation pits for building construction and a construction method thereof. Background technique [0002] Deep foundation pit refers to a project where the excavation depth exceeds 5 meters, or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. In order to ensure the safety of the underground construction and the surrounding environment of the foundation pit, it is usually necessary to build a support structure in the deep foundation pit and the surrounding environment. [0003] In the prior art, the application number is "202010561465.X" for a deep foundation pit construction structure and deep foundation pit construction method. Two layers of columns arranged staggered are inserted into the side wall of the foundation pit to...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many defects in the prior art, such as: 1. no drainage device is provided in the deep foundation pit in the above-mentioned technology, and the problem of accumulation of water is prone to occur in the deep foundation pit, and the long-term accumulation of water will corrode the internal structure of the deep foundation pit, causing potential danger; 3. The deep foundation pit in the above technology is not designed with structures such as stairs, which brings great inconvenience to the entry and exit of the staff
