Description

Technical Field

[0001] The utility model relates to the technical field of falling-rock prevention devices, in particular to a top falling-rock prevention device for tunnel safety construction protection. Background Technique

[0002] A tunnel is an engineering structure buried in the stratum and is a form of human utilization of underground space. For regions with more mountains, in order to form convenient transportation and build roads, tunnels are essential transportation facilities, and the common one is a traffic tunnel. Tunnels are located underground and in mountains, especially mostly in mountains. Therefore, during use, stones or hard soil will slide down from the mountaintop, posing uncertain safety hazards to passing vehicles. Especially during the construction process, due to the lack of corresponding reinforcement at the top, the crushed stones, soil, etc. on the tunnel top will fall when vibrated during the construction process, causing damage to construction workers and equipment, and there are certain safety hazards.

[0003] Currently, most of the methods for preventing falling rocks in tunnel construction are to fix a metal mesh on the tunnel top to intercept the falling stones. Although the structure is simple, it is found during use that due to the limitations of materials and structures, it is very difficult for a simple metal mesh to intercept larger stones, and the interception effect of a single metal mesh on falling rocks becomes poor. Moreover, for the existing single metal mesh, when the overall layout is partially damaged, it needs to be replaced as a whole, increasing the use cost, and the metal mesh set for different tunnels cannot be recycled after being removed, resulting in waste of resources.
