Subway station reserved underpass structure system and construction method thereof
The invention provides a subway station reserved underpass structure system and a construction method thereof. The subway station reserved underpass structure system comprises a subway station foundation pit and foundation pit supporting structures located on the two sides of the subway station foundation pit, and the subway station foundation pit comprises a pre-built subway station structure and a reserved underpass structure located below the pre-built subway station structure; the pre-built subway station structure comprises a top wall, a bottom plate, structural columns and side walls; the reserved underpass structure comprises a foundation reinforcing area, supporting piles and a ground beam; the whole reserved underpass structure is filled with the foundation reinforcing area, and a later interval tunnel is arranged in the foundation reinforcing area; the supporting piles correspond to the structural columns and the side walls of the pre-built subway station structure in the vertical direction and are downwards inserted into the foundation reinforcing area; and the ground beam connects the supporting piles with one another at the top ends of the supporting piles, so that the ground beam and the supporting piles integrally form a frame structure.
本发明提供了一种地铁车站预留下穿结构体系及其施工方法。地铁车站预留下穿结构体系包括：地铁车站基坑、以及位于地铁车站基坑两侧的基坑支护结构，地铁车站基坑包括先建地铁车站结构和位于先建地铁车站结构下方的预留下穿结构；其中先建地铁车站结构包括顶墙、底板、结构柱和边墙；预留下穿结构包括：地基加固区，地基加固区填充整个预留下穿结构内部，且地基加固区设置有后期区间隧道；支撑桩，支撑桩与先建地铁车站结构中的结构柱和边墙在竖直方向上相对应，并向下插入地基加固区内；以及地梁，地梁在支撑桩的顶端将支撑桩相互连接从而与支撑桩整体形成为框架结构。
