Description

Falling stone passive flexible protection device

Technical Field

The utility model relates to a slope improvement field especially relates to a passive flexible protector of falling rocks.

Background

The strip mine side slope falling rock means that individual stones fall, rebound, jump, roll or slide along a slope surface after losing stability from the surface of the strip mine side slope due to the influence of various factors such as blasting vibration, weathering, rainwater and the like, so that the strip mine side slope falling rock is formed. With the continuous advance of strip mine mining, more and more high and steep slopes are formed, so that the problem of falling rocks on the strip mine slopes becomes more and more prominent, and the falling rocks disaster not only brings great potential safety hazards to mines and seriously affects the continuous normal production of the mines, but also endangers the life of workers and the equipment safety. Technical measures commonly adopted at present for preventing the side slope falling rocks of the strip mine comprise: (1) Cleaning platforms are arranged at intervals of a certain height and used for intercepting the sliding stones and cleaning with equipment; (2) Reasonable protective measures are taken to intercept the falling rocks of the side slope of the strip mine.

The mine that is usually adopted at present is passive flexible protection system, includes: steel wire rope net (or ring net), high-strength steel wire grid net, anchor rod, I-shaped steel column, upper and lower pull anchor ropes, pressure reducing ring, base and upper and lower supporting ropes. A steel column and a steel wire rope net form a surface area to prevent loose rock blocks from falling, in order to prevent small rock blocks from falling, a layer of high-strength iron wire grid net is attached to the steel wire rope net (or an annular net), and the steel column is connected with the base through a movable hinge. Meanwhile, in order to offset the impact force of falling rocks of the side slope, the buffer device is mainly formed by components such as a reinforcing steel rope net, a pressure reducing ring and the like. However, the current protection system has the following problems: (1) The buffer device of the protection system mainly depends on a pressure reducing ring, a reinforcing steel rope net and other devices, and once the interception of large falling rocks is completed, the pressure reducing ring cannot be reused after energy dissipation, so that the protection system can be used only by replacing new components in time, and is inconvenient to maintain. (2) A large amount of less stones that drop from the side slope body, along with time lapse, a large amount of accumulations are in the lower part of protection network, and difficult clearance forms protection network bottom "drum belly" phenomenon (3) wire rope net (or annular net) and takes place the damaged back, and difficult repair can reach the protecting effect after generally needing whole the change, causes life weak point.

There is a need for a passive flexible protection against falling rocks which solves the above mentioned problems.
