Open cut column-free arched subway station unearthing structure and construction method
The invention provides an open-cut non-column arched subway station unearthed structure which comprises a station body structure, a vertical supporting structure, an enclosure structure and a soil retaining structure, the station body structure comprises a top plate, a middle plate, a bottom plate and two side walls oppositely arranged in the transverse direction, and an upper-layer underground space is defined by the top plate, the side walls and the middle plate; a lower-layer underground space is defined by the middle plate, the side walls and the bottom plate; the vertical supporting structure is supported between the top plate and the bottom plate, two top plate soil outlets oppositely formed in the two sides of the vertical supporting structure are formed in the top plate, and two middle plate soil outlets oppositely formed in the two sides of the vertical supporting structure are formed in the middle plate; the soil retaining structure is fixed to the top plate and encloses the soil outlet of the top plate. In this way, a cantilever structure is prevented from being formed around the hole, the structural rigidity is guaranteed, related components can be detached after construction is completed so as to be reused, construction is convenient, economical efficiency is good, and development and utilization of the internal function space and the surrounding underground space of the structure are not affected.
本发明提供一种明挖无柱拱形地铁车站出土结构，包括车站主体结构、竖向支撑结构、围护结构以及挡土结构，车站主体结构包括顶板、中板、底板以及两个沿横向相对设置的侧墙，顶板、侧墙和中板之间合围形成上层地下空间，中板、侧墙和底板之间合围形成下层地下空间；竖向支撑结构支承于顶板和底板之间，顶板上开设有两个相对设置于竖向支撑结构的两侧的顶板出土孔，中板上开设有两个相对设置于竖向支撑结构的两侧的中板出土孔；挡土结构固定于顶板上，并围护于顶板出土孔处。如此避免开孔处周围形成悬臂结构，保证了结构刚度，施工完成后可拆卸相关构件，以重复利用，施工便利，经济性良好，且不影响结构的内部功能空间和周围地下空间的开发利用。
