Semi-reverse construction method for large-span corridor structure along street

Abstract

The invention discloses a semi-reverse construction method for a large-span corridor structure along a street. During construction, a foundation pit support and a basement structure are constructed in sequence, an overground structure is constructed by adopting a semi-reverse construction method, the construction efficiency can be effectively improved and the cost can be saved by combining cross construction of the foundation pit support and the basement structure and the overground structure, more operation time is provided for other professional insertion construction, and the project delay risk is reduced. According to the construction method, construction of an underground diaphragm wall maintenance structure and supporting columns is completed on the ground firstly, then earthwork excavation, inner support construction and bottom plate construction are sequentially conducted, then a creeping formwork is adopted for constructing corridor structure columns to a corridor structure layer on the ground, a corridor steel structure is installed, and other structure floors are sequentially and upwards constructed; and in this way, the overground and underground structures are convenient to operate, mutual assistance is achieved, the influence of a construction working face is avoided, the construction period can be greatly shortened, and construction quality is guaranteed. According to the method, the traffic influence on a commercial core area is reduced, the road occupation of a project is reduced, and more construction working surfaces are provided.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a semi-upside-down construction method for a large-span corridor structure along a street. Background technique [0002] With the development of the construction industry, more and more twin-tower buildings, new buildings and old buildings connected buildings are emerging, because of the large building volume, long development cycle, market uncertainty, etc., coupled with the planning problems at the beginning of the city, the twin towers Buildings often need to be developed in phases. Therefore, in order to connect the twin towers together to form an overall development value, it is necessary to erect corridors (including above-ground corridors and underground passages) between the twin towers. However, since most super high-rise buildings are located in commercial core areas, the traffic is heavy, especially long-span cross-street corridors involve lo...
