A construction method of basement retaining wall based on brick membrane molding wall

Abstract

The invention discloses a method for constructing a basement retaining wall based on a brick base membrane modeling wall. The method comprises the following steps that firstly, the modeling wall is arranged on the pit wall of a foundation pit of a basement, then construction of waterproof roll material is conducted on the outside surface of the modeling wall to obtain a waterproof layer of the retaining wall, and the modeling wall and the waterproof layer of the retaining wall form a basement retaining wall outside support to complete pouring of the basement wall retaining wall. The method is characterized in that brick membrane serves as a support, a support pile at the outer side of the pit wall of the foundation pit is placed into a welding screw rod to be connected with the brick membrane, and then the modeling wall is obtained by pouring. The method for constructing the basement retaining wall based on the brick base membrane modeling wall has the advantages of simple construction, a short construction period, low cost, a good waterproofing effect, and the like; and the method is particularly suitable for implementation and application foundation construction of a high-rise building with the deep foundation pit.

Description

technical field [0001] The invention belongs to the field of building foundation engineering construction, and in particular relates to a basement retaining wall construction method based on a brick membrane molding wall. 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. [00...

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
