Problems solved by technology

However, the distance between the basement retaining wall and the foundation pit support system caused by excavation without fertilizer grooves 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 basement is needed Retaining wall and its construction technology to solve such problems

Abstract

The invention discloses a basement retaining wall constructed in a no-fertilizer tank mode. The basement retaining wall comprises a basement retaining wall body which is poured on a pre-arranged retaining wall foundation on the ground surface of a basement foundation pit, and the outer side face of the basement retaining wall body is provided with a waterproof layer made of a rolled waterproof material. The basement retaining wall is characterized in that a molding wall body adheres to the outside of the waterproof layer and is obtained by pouring concrete, and the outer side of a molding wall is connected with the wall of the foundation pit in a pouring mode; a soil layer outside the wall of the foundation pit is further provided with a vertically embedded supporting pile; welded screw rods are horizontally arranged between the supporting pile and a brick wall; and one ends of the welded screw rods are fixed into open holes of the supporting pile in a welding mode, and the other ends of the welded screw rods are fixed into the molding wall in a pulling connection mode. The basement retaining wall has the advantages of being easy to construct, short in construction period, low in cost, good in waterproof effect and the like, and is especially suitable for being applied to construction of a building foundation of a high-rise building with a 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 constructed without a fertilizer tank. 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. [0003] The construction ...
