Soft rock excavation supporting aid

Abstract

The present application relates to a soft rock excavation supporting aid, which relates to the field of soft rock excavation supporting technology, and includes two supporting mechanisms (1), wherein the supporting mechanisms (1) include two supporting parts connected by hinges, and the supporting parts are connected to a hydraulic cylinder (104), and the hydraulic cylinder (104) is used to drive the two supporting parts to expand and contract. The present application provides for the provision of two supporting mechanisms (1), each of which consists of two hinged supporting parts. By driving the hydraulic cylinder (104), the supporting parts can be rapidly expanded and contracted, closely adhering to the surface of the soft rock wall, effectively preventing the collapse of the tunnel wall and improving the supporting efficiency. The introduction of the hydraulic cylinder (104) simplifies the supporting process, reduces labour requirements and improves construction efficiency.
