Structure of subway underground excavation station project
The invention discloses a subway underground excavation station engineering structure which comprises a first lower pilot tunnel and a second lower pilot tunnel which are arranged in a spaced mode, and a first upper pilot tunnel is formed above the first lower pilot tunnel. Block-by-block and section-by-section pouring is carried out on the arch lining, the limited construction operation space is fully utilized, and the construction difficulty is reduced. The arch lining seam can be of a bracket structure, the force exerting area is increased, and the multi-arch lining integrity is good. The technology is feasible, safe and reliable, the quality is controllable, the benefits in the aspects of guaranteeing the construction period and saving the cost are obvious, and good economic benefits can be obtained.
本发明公开了一种地铁暗挖车站工程的结构，包括两个间隔设置的第一下部导洞和第二下部导洞，第一下部导洞的上方开设有第一上部导洞。本发明对拱部衬砌进行分块分段浇筑，充分利用有限的施工作业空间，减低施工难度低。拱部衬砌缝可以采用牛腿结构，增大着力面积，连拱衬砌整体性好。本发明技术可行、安全可靠、质量可控，在保障工期、节约成本方面效益明显，能够取得良好的经济效益。
