Description

Technical Field

[0001] The utility model relates to the technical field of tunnel support, in particular to an exploration tunnel support component. Background Art

[0002] With the rapid development of tunnels and underground projects in my country, such as railway tunnels, highway tunnels, and water supply tunnels, numerous tunnel surrounding rock collapse accidents have occurred during the construction and operation of tunnels due to adverse geological structures, excavation disturbances, and other factors. To address the stability of tunnel surrounding rock, many projects and researchers have implemented various support measures. For example, application publication number CN113090310A discloses a multi-directional tunnel support system comprising a plurality of annular supports and a plurality of axial supports. The annular supports are connected by an annular deformation structure to form an annular support, and the axial supports are connected by an axial-transverse deformation structure to form an axial support. The annular supports are arranged in parallel and equidistantly. This system provides a more comprehensive and safer solution to the problems caused by tunnel surrounding rock deformation in the axial, radial, and circumferential directions. However, the annular supports are welded to the axial supports. If welding or lashing is used within the tunnel, the tunnel operating space is limited and the connection method lacks uniformity. This welding operation poses a safety hazard, particularly in gas tunnel work areas, and does not comply with the "Technical Specifications for Railway Gas Tunnels."

[0003] Therefore, there is an urgent need for an exploration tunnel support assembly that is simple to operate and quick to assemble. Utility Model Content
