Description

Technical Field

[0001] The invention relates to the technical field of subway open-cut station support, and in particular to a detachable support structure for a subway open-cut station. Background Art

[0002] In subway construction, we often use three methods: open excavation, dark excavation, and covered excavation. Open excavation refers to an underground construction method that first digs the ground, builds lining in the open air, and then covers and backfills. It is mostly used for shallow buried tunnels. Open excavation is the most basic and most commonly used construction method in soft soil underground construction. Open excavation is a construction method that excavates a foundation pit under the protection of a certain support system, and then constructs the main structure of the underground project in the foundation pit.

[0003] The support structure of the subway open-cut station is often supported by metal support rods, which are then fixed by multiple bolts. Disassembly and assembly are time-consuming, and it is not convenient to quickly disassemble and connect the metal support rods during open-cut construction. There is no way to make corresponding adjustments according to the on-site conditions, which ultimately affects the support strength and causes unstable support for the earthwork, resulting in safety accidents. Therefore, in order to solve this problem, it is very necessary to design a detachable support structure for the subway open-cut station. Summary of the invention
