Construction method of deep foundation pit basement concrete outer wall

Abstract

The invention discloses a construction method of a deep foundation pit basement concrete outer wall, and relates to the technical field of building construction. The construction method comprises thesteps that concrete reinforcements are bound between the inner side of the designed basement concrete outer wall and a foundation pit perpendicular support vertical surface, limiting reinforcements are arranged between the inner side of the basement concrete outer wall and the foundation pit perpendicular support vertical surface, an inner side formwork is erected on the inner side of the basementconcrete outer wall, then pouring of the basement concrete outer wall is conducted. According to the construction method, the foundation pit perpendicular support vertical surface serves as an outerside formwork of the basement concrete outer wall, therefore, construction of an outer wall of a new building can be conducted no matter how small the distance between adjacent buildings is to any degree, the formworks on the two sides are arranged all the same, construction of the concrete outer wall is conducted all the same, the quality of the outer wall is ensured, meanwhile, construction is convenient, and the rigidity, strength and stability of the formworks are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, and is mainly applicable to the building technology of concrete outer walls of deep foundation pit basements. Background technique [0002] The land resources for the construction of modern cities are becoming more and more tense. There are many high-rise buildings in the city, and the buildings under construction generally use underground civil air defense facilities as garages. This not only saves land resources, but also fully improves the use efficiency of construction projects. war combination. [0003] Generally, cast-in-situ piles are used to protect the wall of deep foundation pits, which can reduce the slope of the slope or even not slope it, and ensure the safety of the buildings around the foundation pit. But, the distance between adjacent buildings in the city is short and can't carry out double-sided support formwork, therefore, with regard to present building construc...

Problems solved by technology

[0004] Aiming at the problem that the gap between the concrete outer wall of the basement of a deep foundation pit and the vertical retaining wall of the deep foundation pit is small, and the formwork support on both sides of the outer concrete wall of the basement cannot be normally carried out, the present invention proposes a concrete outer wall of the basement of a deep foundation pit.
