The passive protective mesh is composed of wire rope mesh, high strength wire mesh, anchor rod, I-steel column, up and down anchor rope, energy dissipation ring, base and up and down support rope. The system is composed of steel column and steel rope net, which form a whole, and form slope protection for the protected area, thus preventing the collapse of rock falling, and playing a role in slope protection.

The passive protection net is similar to the standard active protection system in form, but it mainly plays the role of passive protection. The main difference between the flexible mesh system and the standard active reinforcement system is that the system does not need to be anchored and pre-tensioned to ensure that the system is as close to the slope as possible, and the flexible mesh system can be naturally covered (draped) on the slope only by peripheral and internal local anchorage, or even can be suspended only by upper anchorage and upper support rope. To form the simplest "curtain" structure. It not only provides a certain stabilizing and reinforcing effect for the potential collapse and sliding body by means of the self-weight overlap pressure of the system, but also restricts the occurrence of the collapse partly, and allows the rockfall to roll down the slope to the foot of the slope safely under the controlled condition. Platform does not endanger safety protection, but does not prevent the occurrence of collapse. It is a very effective and economical method for high and steep slopes with concentrated area, high frequency of collapse and rockfall or difficult slope construction. Compared with the passive protection system, the main advantages of this method are that the cleaning work is very simple or need not be cleaned up, and it avoids the possible rockfall flying when the passive protection system protection height is insufficient. This method is more economical when the slope height is not too high, and the two methods can be used together under certain conditions. The system can not only be used for the protection of rockfall but also for Blasting Fly Rock protection.
Material: wire rope net, supporting rope and decompression ring.
Structure: It consists of wire rope mesh or ring mesh (adding a layer of wire grille when intercepting small pieces of rock fall), fixing system (anchor, anchor rope, base and supporting rope), pressure reducing ring and steel column.
Product characteristics:
The flexible protection and interception strength of the system are enough to absorb and disperse the impact kinetic energy of the rock. The design and application of the pressure reducing ring can further improve the impulse of the system.
It is suitable for high mountains with buffer zones beside construction facilities. It can intercept rock avalanches, flying rocks, avalanches and debris flows outside construction facilities to avoid damage to construction facilities caused by disasters.
