Slope Protection Rope Mesh Slope Protection Netting For Prevention Falling Rocks
Slope protection rope mesh ,also named slope protection netting or SNS slope protection mesh , is made up of two layers mesh: the inner is gabion mesh or chain link mesh and the outer is stainless steel knotted rope mesh or stainless steel ferrule rope mesh. It is unrolled or draped over the slope and fixed with anchor bolts.Slope protection rope mesh is mainly used to prevent rocks from falling onto roads, railways and other structures. In this situation, rocks will fall to the foot of slope behind the slope protection rope mesh instead of falling onto the roads. So it can guarantee the safety of passengers. Besides, it can prevent various slope geological disasters, such as snow slide, slope erosion and flying rocks.
slope protection rope mesh installation method:
The use of slope protection netting is one of the most widely used rock fall mitigation methods in the world, especially for controlling high-frequency and low-intensity rock fall on small and medium-sized slopes. There are two main installation methods for slope protection netting: hanging installation and anchoring installation.
Overhang installation
Supported by a bearing rope fixed on the leading edge of the slope.slope protection rope mesh covers the slope in a way that maximizes slope contact. The slope is allowed to erode behind the grid layer, and the grid layer acts as a barrier to control the debris from moving down the slope, usually entering the catchment ditch at the bottom of the mountain.
The most important material parameters to be considered when designing are unit weight, tensile strength and puncture strength. As the need to control larger fragments increases, so does the need to install slope protection rope mesh
The slope protection rope mesh of overhang installation has the following characteristics
● Low material cost
● Low installation cost
● Free drainage
● Reduce engineering workload
● Reduce slope erosion
● Cannot replant vegetation
● Need catchment area/ditch
● Higher maintenance costs
Anchor installation
A dense matrix of soil or rock anchors and special anchor plates is used to anchor the net on the slope, and the rock net is fixed on the slope with rock anchors. Rock anchors are made by inserting steel rods into grouted small-diameter holes that are drilled to a specific depth in the rock. The depth and capacity of the anchor depend on the rock type and system design. The most important material parameters to consider when designing are tensile strength and puncture strength.
The slope protection rope mesh of anchor installation has the following characteristics
● The slope is not eroded (the dangerous process stops)
● Can revegetate
● Free drainage
● No catchment area required
● Low maintenance
● Need higher engineering effort
● Due to the increase in the number of anchors, the installation cost is higher
● Higher material cost
Advantages of slope protection rope mesh:
Simple installation and easy to spread.
High flexibility.
Soft but high protective strength.
Adapt to any slope terrain.
Resistant to rust and long work life.
Easy to repair and maintenance-free.
