Description

Decompression buffer device

Technical Field

The application relates to the technical field of protection net systems, in particular to a decompression buffer device which plays a role in protecting against impact in a protection net system.

Background

At present, a relatively wide passive flexible protection system for slope protection is composed of four main parts of a steel wire rope net, an annular net (an iron wire grid is added when small falling rocks need to be intercepted), a fixing system (an anchor rod, an anchor rope, a base and a supporting rope), a decompression ring and a steel column. The steel column and the steel wire rope net are connected and combined to form a whole to form surface protection for the protected area, thereby preventing falling of collapsed rock soil bodies and playing a role in slope protection. The method is suitable for mountain steep mountains with buffer zones beside building facilities, and can intercept rock collapse, flying stones, avalanche and debris flow outside the building, road and other facilities, so as to avoid damage of disasters to the building, road and other facilities.

When the passive protection system encounters large falling stone impact, the key component decompression ring can start to play a role: the steel wire rope passing through the decompression ring rubs with the inner wall of the ring, and the decompression ring is gradually stretched after yielding deformation until maximum deformation, and the steel wire rope is straightened and bears the maximum pulling force and the final pulling force, so that the decompression ring is not deformed any more. After the impact is terminated, the denatured decompression ring cannot recover, and the steel wire rope cannot be loosened after being meshed with the damaged decompression ring. If the function of the passive protective net is to be recovered, the passive protective net is enabled to play a role again, and the falling stone impact is borne again, the steel wire rope and the decompression ring which are related to the decompression ring are required to be thoroughly replaced, the replacement labor intensity is high, the construction period is long, the replaced decompression ring and the replaced steel wire rope cannot be reused, and the maintenance cost is high.
