Problems solved by technology
Compared with rigid sheds, flexible sheds have the advantages of light weight, high protection energy level, convenient construction, and good economy. The energy dissipator, when subjected to the impact of the design energy level, the energy dissipator will undergo irreversible plastic deformation and needs to be replaced frequently
At the same time, in general flexible steel shed holes, falling rocks may be trapped by the mesh, and the long-term accumulated falling rocks will cause a huge cleaning workload

Embodiment Construction
[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] like Figure 1-3 As shown, the cantilevered self-restoring flexible protective shed hole of the embodiment of the present application is characterized in that it includes: a support rod 4, an annular net 3, a piston rod 2 and a support rope;
[0027] The support bar 4 constitutes the main force truss, including an in-plane support bar...

The invention provides a cantilever type self-restoring flexible protective shed cave suitable for rockfall protection projects on high and steep slopes, which includes an annular net for intercepting rockfall, a rigid support rod for supporting the annular net, a piston rod, and a support rope A shackle for connecting the ring net and a support rope and a spring connected to the support rope, and the support rope and the support rod are connected to a nearby steep mountain through an anchor support. Compared with the existing traditional shed cave, the present invention is a cantilever structure that only needs to set a support on one side of the road. Situations where it is not convenient to set up a reliable support. The invention has the ability of recovery and self-cleaning of falling rocks, and greatly reduces the operation and maintenance cost after being put into use. At the same time, the self-restoring flexible protective shed hole of the present invention has the characteristics of convenient on-site assembly, small dead weight and good economy.
Description
technical field [0001] The invention relates to the technical field of slope protection, in particular to a cantilever type self-restoring flexible protective shed hole. Background technique [0002] About 2 / 3 of my country's land area is mountainous, and disasters such as falling rocks and landslides have occurred frequently since ancient times. Effective protection of them is related to the safety of people's livelihood and the effective operation of important infrastructure. Sheds are often used for rockfall protection on mountain roads, railways, and tunnel entrances to ensure driving safety. Compared with rigid sheds, flexible sheds have the advantages of light weight, high protection energy level, convenient construction, and good economy. When impacted by the design energy level, the energy dissipator will undergo irreversible plastic deformation and needs to be replaced frequently. At the same time, falling rocks may be caught by the nets in general flexible steel ...
