Underground complex integrally co-constructed implementation design method

Abstract

The invention discloses an underground complex integrally co-constructed implementation design method. A co-constructed mode of the invention is adopted for the construction of a basement and a subway station of a development lot. The method comprises the following steps of: separately constructing end wells at both ends of a subway so as to meet the run-through requirement of a running tunnel, and meanwhile, developing a pile foundation and an enclosing structure of the business development lot; and after the end well structures of the subway station are finished, carrying out integral excavation on a foundation pit of a standard section of the basement and the subway station of the development lot. In the design method, the construction period requirements of the basement and the subway station of the business development lot are researched, and then foundation pit regions are reasonably designed; and a corresponding enclosing support design measure is adopted, and on the premise of guaranteeing the engineering quality and a construction period, the engineering construction cost and the development period are maximally saved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a design method for foundation pit partition planning and implementation, in particular to an implementation design method for integrated co-construction of an underground complex. Background technique [0002] With the massive development of urban underground space and the development of urban rail transit, it has become a development trend to set up subway stations in commercial development plots and adopt a co-construction model for construction. In order to ensure the maximum utilization of the underground space of the development plot and the best technical and economic efficiency, the station is often set under the basement floor of the development plot. Existing technology at present generally constructs and excavates the deeper subway station foundation pit earlier, and after the station civil engineering is completed, then excavates the development plots on b...

Problems solved by technology

This phased implementation can ensure that the station is completed on schedule, but since the foundation pit of the development plot needs to wait for the subway structure to be completely completed before excavation, the overall construction period of the underground complex is too long, which affects the development and use of the plot; Sectional foundation pit also needs to set up a separate enclosure structure and support system from the ground to the bottom of the pit, which not only affects the construction period, but also increases the construction cost; therefore, it is difficult to achieve the effect of co-construction with traditional implementation methods, and the technical and economical efficiency of plot development is low.
