Description

Rigid-flexible damping interception type protection system

Technical Field

Background

The flexible protection system is a slope protection technical system which originates in Europe in the 20 th century and has almost 100 years so far, and is divided into an active protection system and a passive protection system, wherein the active protection system is covered and wrapped on a slope or dangerous rock to be protected by a steel wire (rope) net, a grid net (twisted pair net), a supporting rope, an anchor rod and other structures so as to limit weathering stripping or partial collapse (covering and fixing effect) of the dangerous rock on the slope; the passive protection system combines and supports structures such as steel columns, supporting ropes, pull ropes, anchor rods, pressure reducing rings, steel wire (rope) nets, grid nets (twisted pair nets) and the like in the falling area of dangerous rocks to intercept (intercept guiding effect).

The existing passive protection net system is divided into a passive diamond net and a passive ring net according to the shape of the outer net, and the two passive net systems have basically the same structure except the shape of the outer net, and specifically comprise the following components: screw anchor rod, base, connecting bolt, stand, pin, round pin section of thick bamboo, supporting rope, stay cord stock, stay cord, diamond-shaped net piece and suture rope (for passive diamond-shaped net), annular net piece and shackle (for passive annular net), decompression ring, intranet (grid net or twisted hexagonal net), rope clip, tie wire and other structures. The construction process of the passive protective net comprises the steps of firstly finding out the point positions, then measuring and paying off, then excavating a column foundation (600 mm is multiplied by 800mm is multiplied by 1000mm is miniature foundation) and a pull rope foundation (600 mm is multiplied by 2500mm is miniature foundation), then respectively embedding a threaded anchor rod and a pull rope anchor rod into the column foundation and the pull anchor foundation, after the strength of foundation concrete meets the installation condition of the passive protective net, installing a column, tensioning a pull rope with a decompression ring and an upper supporting rope and a lower supporting rope, and then hanging an outer net and an inner net, thus the installation of the passive protective net can be completed. When the passive protective net is impacted by falling rocks with certain energy, the inner net (grid net or twisted hexagonal net) and the outer net (diamond net or annular net) bound together are deformed by impact force and absorb energy, meanwhile, the stressed inner net and outer net transfer residual energy to the upper supporting rope, the lower supporting rope and the decompression rings on the supporting ropes, so that the decompression rings are deformed to continuously absorb energy, the residual energy of the upper supporting rope is further transferred to the top of the upright post, the top of the upright post is stressed to exceed the load borne by the upright post to generate lateral bending and absorb energy again, at the moment, the stay ropes and the decompression rings on the stay ropes are stressed and started by the impact energy transferred from the top of the upright post, deformation and energy absorption are generated, and part of energy is transferred to the miniature upright post foundation and the anchor pulling foundation, and the situation that the miniature foundation is damaged due to small stress is generated.

After the passive protection net system is impacted by falling rocks with certain energy, the following result is that: the inner and outer meshes are seriously deformed, and the deformed meshes can only be scrapped integrally and cannot be repaired; the upright post of the I-steel can generate lateral bending when receiving certain impact energy because of lower bending strength of the side surface, and the structure leads the whole protection system not to bear larger impact; the pressure reducing ring can be seriously deformed and even pulled into a straight line, and the deformed pressure reducing ring can only be scrapped and cannot be repaired, so that the pressure reducing ring cannot be reused; the micro foundation cannot bear the impact force matched with the energy level; the service life of the existing passive network system is actually far lower than that of the design target.
