Embodiment Construction
[0029] The present invention adopts the method of coordinating the excavation of foundation pit earthwork by sections and the subsection pouring of the main structure. The excavation of foundation pit earthwork is divided into N sections for construction, and the corresponding main structure is also divided into N sections for construction, and the construction joints are avoided. The shield stacking area should be located at the place where the force is the smallest; the upper open-cut tunnel construction in the shield stacking area is excavated to the bottom of the foundation pit, and the bottom plate construction is carried out in time, and the trolley is moved to the bottom plate (increasing the load). After the truck is moved in place, the trolley is used to pour the main structure of the upper cut-and-cut tunnel in the stacked section. At the same time, the shield tunnel passes through the open-cut tunnel under construction synchronously from the bottom of the cut-and-cut ...
