AI Technical Summary
During the construction of the reverse wall, when excavating the soil and rock on one side between the staggered retaining piles, the soil and rock near the retaining piles on the other side are prone to collapse, and the temporary support needs to be removed after it is added, which affects the construction progress.
Design a steel frame structure for reverse-construction wall casting, including a first retaining pile and a second retaining pile, and form a casting steel frame by connecting the bent sections of the first wall frame and the second wall frame to support the soil and rock to prevent collapse and ensure the uniformity and structural strength after casting.
It improves the safety and progress of reverse wall construction, ensures the structural strength and uniformity of the reverse wall, and reduces the time required for the use and removal of temporary supports.
