Abstract
Urban subway construction is often in the lower part of the city center road, and there are many municipal pipelines and pipelines in the lower part of the road. Because it involves the life of the surrounding residents, it is difficult to move and change. In the open excavation of foundation pit, the whole suspension construction measures are often used to solve this problem. Within the excavation area of the Yingmentan Station passageway of Lanzhou Rail Transit Line 1, there is a steel pipe municipal water supply pipeline. This municipal water supply pipeline needs integral suspension protection, with a suspension span of 22.5m. The design adopts T-shaped truss beams for overall suspension. This paper uses T-shaped beam design and force analysis research. Provide reference for similar projects.
