A construction method of basement retaining wall based on concrete pouring molding wall

Abstract

The invention discloses a basement retaining wall construction method based on concrete pouring of a modeling wall. The basement retaining wall construction method comprises the following steps: the modeling wall is arranged on the wall of a basement foundation pit, waterproof roll construction is performed on the outer side surface of the modeling wall to obtain a retaining water water-proof layer, and a basement retaining wall outer side support is formed by the modeling wall and the retaining wall water-proof layer to finish pouring of a basement retaining wall. The basement retaining wall construction method is characterized in that welding screw rods are embedded into a supporting pile on the outer side of the wall of the foundation pit to realize supporting and pouring of a modeling wall template to obtain the modeling wall. The basement retaining wall construction method has the characteristics that the construction is simple, the construction period is short, the cost is low and the water-proof effect is good, and is particularly suitable for implementation and application in building foundation construction of high-rise buildings with relatively deep foundation pits.

Description

technical field [0001] The invention belongs to the construction field of building foundation engineering, and in particular relates to a basement retaining wall construction method based on pouring concrete molding walls. Background technique [0002] With the development of economy and the continuous growth of population, land resources are becoming more and more urgent. It has promoted the transition of universities from educational land to semi-educational land and semi-commercial land, and a large number of comprehensive commercial buildings have sprung up like mushrooms after rain. However, commercial buildings must not only meet the requirements of the school’s teaching land, but also meet the requirements of commercial profitability. Therefore, commercial buildings are usually located on the side close to the market road, which greatly increases the difficulty of construction. Engineering foundation pit construction tends to excavate without fertilizer groove. [0...

AI Technical Summary

Problems solved by technology

However, the distance between the basement retaining wall and the foundation pit support system caused by the excavation without fertilizer tank is too close, and it is difficult to support the outer formwork of the retaining wall, and the membrane waterproof construction is difficult to construct without a working surface, so a new construction method is required process to solve such problems
