Underground excavation reinforcing structure and method for tunnel below crossing road
The invention discloses an underground excavation reinforcing structure and method for a tunnel below a street-crossing highway, the reinforcing structure is located below the street-crossing highway, and the reinforcing structure comprises an upper supporting bridge structure arranged close to a cushion layer of the street-crossing highway and a lower supporting bridge structure located above an excavated tunnel; the lower supporting bridge structure is located under the upper supporting bridge structure, and a gap is formed between the upper supporting bridge structure and the lower supporting bridge structure. The settlement of the whole road can be well controlled and is not restricted by key time nodes of construction time; station and entrance and exit enclosure structures can be constructed synchronously, time node key lines of the subsurface tunnel are changed into non-key time node lines, the construction period is shortened, and the construction cost is relatively low.
本发明公开了一种过街公路下方隧道暗挖加固结构及其加固方法，所述加固结构位于过街公路的下方，所述加固结构包括靠过街公路的垫层位置设置的上支撑桥梁结构和位于开挖隧道上方的下支撑桥梁结构，所述下支撑桥梁结构位于上支撑桥梁结构的正下方，并且上支撑桥梁结构和下支撑桥梁结构之间具有间距。其能够很好的控制整个公路沉降，不受施工时间关键时间节点制约；车站及出入口围护结构施工时可以同步施工，使暗挖隧道时间节点关键线路变成非关键时间节点线路，缩短了施工工期，施工成本相对较低。
