Station deep foundation pit reinforcing system for underneath passing tunnel and construction method
The invention discloses a station deep foundation pit reinforcing system of an underpass tunnel and a construction method, and belongs to the technical field of station foundation pit construction.The station deep foundation pit reinforcing system of the underpass tunnel comprises existing tunnel fender posts, existing tunnel side walls and existing road structure layers, the existing tunnel side walls and the existing road structure layers are arranged between the existing tunnel fender posts, and foundation pits are excavated in the bottoms and the lower portions of the existing tunnel side walls; a top plate supporting assembly is arranged at the bottom of the foundation pit, a plurality of foundation pit stand columns are arranged below the top plate supporting assembly, and the upper end of the top plate supporting assembly is connected with the side wall of the existing tunnel through a backfilling structure. The overall excavation construction efficiency of the subway station deep foundation pit below the tunnel is greatly improved, and the method has practical significance in subway station deep foundation pit construction.
一种下穿隧道的车站深基坑加固系统及施工方法，属于车站基坑施工技术领域，该所述下穿隧道的车站深基坑加固系统，包括既有隧道围护桩及之间的既有隧道侧墙和既有道路结构层，所述既有隧道侧墙底部和下方开挖有基坑，所述基坑底设置顶板支撑组件，所述顶板支撑组件下方设置多个基坑立柱，所述顶板支撑组件上端通过回填结构与所述既有隧道侧墙相连，本发明的有益效果是，本发明在保证既有道路隧道安全稳定的前提下，极大的提高了隧道下方地铁车站深基坑总体开挖施工工效，在地铁车站深基坑施工中有其现实意义。
