Underpass tunnel structure for preventing lateral deformation of overpass pile foundation and construction method
The underpass tunnel structure for preventing lateral deformation of the overpass pile foundations comprises a tunnel foundation pit and the overpass pile foundations, the tunnel foundation pit is formed between the adjacent overpass pile foundations, the underpass tunnel structure further comprises a tunnel supporting assembly and a pressure guiding assembly, the tunnel supporting assembly is fixedly arranged in the tunnel foundation pit, and the pressure guiding assembly is fixedly arranged in the tunnel foundation pit. The overpass pile foundation is sleeved with the pressure guiding assembly, the tunnel supporting assembly is connected with the pressure guiding assembly, and the pressure guiding assembly is arranged on the outer side of the overpass pile foundation, so that in the tunnel foundation pit excavation process, pressure unbalance of the two sides of the overpass pile foundation is conveniently prevented, and the service life of the overpass is guaranteed; and safe operation of the viaduct in the underpass tunnel construction process is ensured.
一种防止立交桥桩基侧向变形的下穿隧道结构及施工方法，包括隧道基坑和立交桥桩基，隧道基坑成形于相邻的立交桥桩基之间，还包括隧道支撑组件和压力导向组件，隧道支撑组件固定布设在隧道基坑内，压力导向组件套设在立交桥桩基的外侧，隧道支撑组件与压力导向组件连接，通过在立交桥桩基的外侧设置压力导向组件，便于在隧道基坑开挖过程中，防止立交桥桩基的两侧压力失衡，保证立交桥的使用寿命，保证在下穿隧道施工过程中高架桥的安全运行。
