Ring Net Rockfall Systems

Ring net rockfall systems are a type of passive protection system composed of hexagonal wire mesh and steel wire ring net, used for rockfall protection and prevention of geological disasters in various slopes, avalanche slopes, bank erosion, blasting rocks, and rockfall materials.

Galvanized or galfan steel wires.
Special discount for large orders.
Project reference can be supplied for your bid.
SGS Test Report can be provided.
CAD or 3D drawing can be supplied for your design and construction.

Wire Diameter: 3 mm.
Ring Diameter: 300 mm or 350 mm.
Connection Method:

Four contiguous rings

Six contiguous rings

Structure
Ring wire mesh. Combined with steel ring nets, it blocks small rocks or soil during natural disasters (mesh size is generally 60 × 80 mm or 80 × 100 mm).
Steel ring net. Made of high-strength steel wire twisted into circles, circles are interconnected to form a steel ring net, with high load-bearing capacity and more flexibility than steel wire rope nets.
Pressure relief ring. Place along the steel wire ring net to reduce pressure. Made of hot-dip galvanized metal, it is corrosion-resistant and rust-proof.
Support rope: Made of stainless steel wire rope, it has high tensile strength, supports the steel wire rope and pressure relief ring, and can withstand significant impact forces.
Steel column. Installed on the base foundation, it supports the steel wire ring net, and is corrosion-resistant and rust-proof, with high tensile strength. Arrangement can be adjusted according to terrain and environment.
Base foundation. It is used to secure the steel column, treated with hot-dip galvanization to prevent corrosion and rust.

Advantages
Suitable for rock slopes of any steepness, without considering the physical and mechanical properties of the ground.
Only a minimal number of anchor points are needed to secure the top support rope at the edge of the slope.
A top-down installation method is used to ensure that the installation personnel are always in a safe area.
The accumulation area of debris at the bottom of the slope is easy to clean mechanically, without the need for special equipment.
The rockfall curtain requires no maintenance.
There are no weak points in the design.

Applications
Ecological restoration
Road protection
Landslide

The main of the rockfall barrier elements have base plates, Post, Foundations for the rockfall barriers, anchors, intermediate and lateral support ropes for rockfall protection barriers and bearing mesh( ring net or rope net) and brake system.
Rockfall barriers are used by flexible structures. That system deformation for stopping block with impact energy. The increasing deformation the energy system is gradually dissipated through the braking systems.So Application areas of rockfall protection systems depending of impact energy.
So We conduct dynamic tests to test the energy of the system against falling rocks. Determine different energy levels.

Passive slope protection systems are those do not affect the process of the rock detachment, but rather focus on the containing and intercepting falling and sliding debris, therefore averting danger to the infrastructures and its users. Passive protection systems includes simple drapery systems, rockfall protection barriers, rockfall protection embankment.

1.The whole system is flexibly arranged, and various complicated land forms can be photographed, so as to avoid environmental damage caused by excavation and the harm to the stability of the slope, and it is suitable for reinforcement and protection on slopes with landslide hazards. 
2. The unique openness and permeability of the system can ensure that the visual impact on the slope is not damaged. After installing the protective net, plants can be planted on the mountain. The slope protective net can not only stabilize the root system of vegetation, but also divert the water flow, so that the whole slope of the mountain can be evenly absorbed, which protects the mountain from the appearance and reduces the disadvantages of excavation. 
3. The whole system has strong impact resistance and extensibility, which has played a good role in protecting landslides. After the use of the landslide protection net, ideal results have been achieved, which has played an obvious role in stabilizing the slope, effectively controlled the landslide and the deterioration of the landslide, played a decisive role in protecting the interception of rockfall on the slope, and effectively stopped and reduced disasters to a great extent.
