Assembly type double-point fixed foundation pit bridleway structure and construction method thereof

Abstract

The invention discloses an assembly type double-point fixed foundation pit bridleway structure, which comprises a terrace concrete beam, a pile top concrete beam, a bridleway bracket and a bridleway frame body. The bridleway frame body is connected with the bridleway bracket and extends downwards or upwards along the side wall of a foundation pit. The bridleway bracket comprises a bridleway bracket unit and a horizontal cross beam. The bridleway bracket unit comprises a first horizontal longitudinal beam, a second horizontal longitudinal beam, a vertical beam, a first inclined support, a second inclined support and an adjusting base. The foundation pit bridleway structure is connected with a profile steel bridleway bracket through a bridleway frame body. The bridleway bracket serves as a main fixing device for the force bearing and the force transmission of the foundation pit bridleway. The bridleway bracket is fixedly connected with the terrace concrete beam and the pile top concretebeam, so that the pull force applied by a single-point fixed bridleway to the foundation pit can be balanced. The bridleway bracket can reduce slippage and overturning of the slope protection pile into the foundation pit, and plays a good role in protecting the foundation pit.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a foundation pit horseway structure and a construction method thereof. Background technique [0002] With the rapid development of super high-rise buildings in my country, there are more and more deep foundation pit projects. How to transport personnel quickly and efficiently has become a big problem. In the traditional construction, while excavating the earthwork layer by layer, accompanied by the problem of multiple dismantling of the horse track, it not only made the construction process repeated many times, affected the construction period, but also caused unnecessary cost expenditure. In addition, some horse tracks are fixed on the slope protection piles of the foundation pit at a single point, that is, the horse track is only fixedly connected to a concrete platform on the top of the foundation pit. Pit risk factor increased. Contents of the invention [0003] The ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a combined two-point fixed foundation pit horse track structure and its construction method to solve the need to remove the horse track many times when excavating earthwork layer by layer, resulting in repeated construction procedures, affecting the construction period, and causing unnecessary delays. Cost expenditure; when the single-point fixed connection is adopted between the horse road and the slope protection piles of the foundation pit, there is a technical problem that the direction of the external force and the earth pressure of the horse road to the slope protection piles are the same, and the risk factor of the foundation pit is relatively large
