Passive Slope Protection Net
The passive slope net is composed of four main parts: wire rope net, ring net, fixed system decompression ring and steel column. The steel column and wire rope net are connected and combined to form a whole, forming a surface protection for the protected area, thereby preventing the collapse of rock and soil, and playing a role in slope protection.
- Product Introduction
The passive slope net is composed of four main parts: wire rope net, ring net, fixed system decompression ring and steel column. The steel column and wire rope net are connected and combined to form a whole, forming a surface protection for the protected area, thereby preventing the collapse of rock and soil, and playing a role in slope protection. The passive protection net is suitable for rock slope protection with small and scattered rock blocks, and the position, height and kinetic energy of the passive net should be calculated according to the trajectory of rockfall bounce. Its trajectory can be theoretically calculated based on kinematics, and is often determined by on-site rockfall pit investigation and on-site rockfall test in engineering.

Features
Clearly defined protection levels
Product models directly correspond to their protective capabilities (e.g., RXI-200 can withstand a 200kJ impact), ensuring scientific and clear design selection.
01
Maintenance-free design
After intercepting falling rocks, if no structural damage occurs, the system can be quickly restored to functionality by repairing or replacing local components (such as mesh panels and pressure-reducing rings).
02
Strong terrain adaptability
The flexible structure can adapt well to uneven terrain during installation.
03
Standards and certifications
The mature product system (such as the RXI series) adheres to strict international standards (such as EN) and can be verified through third-party testing.
04
Main system components
|
Ring mesh |
It is constructed from multiple interconnected rings woven from high-strength steel wire ropes (tensile strength ≥ 1770 MPa), and serves as the main body that directly intercepts falling rocks and undergoes large deformations to absorb energy. |
|
Pressure relief ring |
This is the most critical energy dissipation component of the system. It is typically installed on the support ropes. When subjected to tensile forces exceeding a threshold, its steel ring is forcibly stretched and deformed, continuously absorbing and dissipating a large amount of energy in the process, effectively reducing the peak load transmitted to the anchor bolts and foundation. |
|
Steel columns and support ropes |
Steel columns (usually H-shaped or I-shaped) form the supporting framework of the system; upper and lower support ropes connect the mesh panels, steel columns, and pressure-reducing rings into a single unit and transfer the load. |
|
Anchoring system |
Including anchor bolts and foundations, the entire system is securely anchored to the ground or stable bedrock, which is the ultimate guarantee of system stability. |
Application Scenarios
Passive slope protection nets are primarily used in the following locations where falling rocks need to be intercepted:
Along roads and railways: Protecting steep slopes and intercepting rocks that may roll onto the road surface.
Mines and power plants: Ensuring the safety of mine slopes, areas below spoil heaps, and access roads to and from hydropower plants.
Mountain buildings and facilities: Protecting buildings, temporary structures, or important facilities located at the bottom of steep slopes.
Scenic areas and ancient trails: Installed alongside tourist paths prone to rockfalls to ensure visitor safety.
