Overhanging type self-recovery flexible protection shed hole

Abstract

The invention provides an overhanging type self-recovery flexible protection shed hole suitable for high and steep side slope rockfall protection engineering. The overhanging type self-recovery flexible protection shed hole includes an annular net for intercepting rockfalls, a rigid supporting rod used for supporting the annular net, a piston rod, and a supporting rope, and further includes shackles for connecting the annular net and the supporting rope and springs connected to the supporting rope, and the supporting rope and the supporting rod are connected to a nearby steep mountain through an anchorage supporting seat. Compared with an existing traditional shed hole, the overhanging type self-recovery flexible protection shed hole is an overhanging structure which only needs to arrange the supporting seat on the road side mountain, suitable for the condition of steep mountain on one side, and is especially suitable for the condition of steep mountain on one side and not easy to arrange the reliable supporting seat on the other side; the overhanging type self-recovery flexible protection shed hole has the abilities of recovering and rockfall self-cleaning, and the operation and maintenance cost after putting into use is greatly reduced; and at the same time, the self-recovery flexible protection shed hole has the characteristics of being convenient to on-site assemble, light in dead weight, and good in 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 ...

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
