Tunnel underground excavation reinforcing structure
The invention discloses a tunnel underground excavation reinforcing structure which comprises enclosure structure pile foundations on the two sides, a pair of bearing platform structures and a pile foundation below a bearing platform arranged below the bearing platform structures, the enclosure structure pile foundations are located on the outer sides of the pile foundation below the bearing platform, and bridge end butt straps are arranged at the tops of the enclosure structure pile foundations on the two sides. An arc-shaped pipe shed structure is arranged on the bridge end butt strap, a reinforcing layer structure is arranged between the bridge end butt straps on the two sides, and a cantilever bridge structure is arranged between the bearing platform structure and the reinforcing layer structure. The tunnel subsurface excavation reinforcing structure is reasonable in design, is supported by the vertically associated reinforcing structures and the arched cantilever bridge, is stable and reliable in reinforcement, can effectively control settlement, fully utilizes the existing main body and enclosure structure pile foundations, and is simple and convenient to construct and relatively low in construction cost.
本发明公开了一种隧道暗挖加固结构，包括两侧围护结构桩基、一对承台结构以及设在承台结构下方的承台下方桩基，所述围护结构桩基位于承台下方桩基外侧，所述两侧围护结构桩基的顶部均设有桥端头搭板，桥端头搭板上设有圆弧型管棚结构，两侧的桥端头搭板之间设有加固层结构，所述承台结构和加固层结构之间设有悬臂桥结构。该隧道暗挖加固结构设计合理，通过上下关联的加固结构以及拱形的悬臂桥支撑，加固稳定可靠，能有效控制沉降，并且充分利用现有主体和围护结构桩基，施工简便，施工成本相对较低。
