Soil discharge platform of foundation pit structure and construction method thereof

Abstract

The invention discloses a soil discharge platform of a foundation pit structure and a construction method thereof. The soil discharge platform comprises multiple steel frames placed on an inner support (1) of the foundation pit; the multiple steel frames are parallel to each other; each steel frame is in detachable connection with the inner support (1); and each steel frame is connected with a steel plate. The construction method comprises the following steps of: implanting a short reinforcing bar (10) and a prefabricated steel frame into the top surface of the inner support (1); fixing the steel frame on the inner support (1); and mounting a steel plate on the steel frame. Through the soil discharge platform of the foundation pit structure and the construction method thereof, the cost is remarkably reduced, the construction period is shortened, and the construction and disassembly processes are convenient and labor-saving.

Description

technical field [0001] The invention relates to the construction field, in particular to an excavation platform of a soft soil deep foundation pit structure and a construction method thereof. Background technique [0002] With the rapid development of urban capital construction and the development of large underground spaces of buildings, the number of building foundation pits is increasing and the scale is increasing. However, due to tight land use and limited space, it is difficult to find space for parking excavators and earth-moving vehicles, stacking building materials (steel pipes, formwork, etc.) A temporary excavation platform for parking excavators and vehicles, stacking building materials and washing vehicles is set up near the edge of the foundation pit. [0003] The unearthed platform of prior art is to adopt the concrete unearthed platform. The construction process of the unearthed platform is as follows: first set up the surrounding protection piles of the fo...

AI Technical Summary

Problems solved by technology

[0004] The unearthed platform and the construction method of the foundation pit structure of the prior art have the following defects: first, after the excavation of the foundation pit is completed, and the construction of the basement exterior wall is also completed, the unearthed platform has completed its mission and is destroyed and removed together with the support in the foundation pit. The destroyed and dismantled concrete, steel bars and other materials cannot be reused, so the waste is serious and the cost remains high; secondly, the process of constructing the unearthed platform is cumbersome and laborious, requiring laying formwork, binding steel cages, pouring concrete, and then waiting for the concrete to dry. Continuing construction after the concrete is hardened, it takes a long time for the concrete to harden, which will prolong the construction period, and the unearthed platform that is time-consuming and laborious construction can only be used once, which is not economically cost-effective; thirdly, the process of dismantling the unearthed platform is also time-consuming and laborious
