The use and construction process of falling stone protective mesh

The use of falling stone protective mesh:

      Widely used in railroads, roads, mines, hydropower projects, slope protection and border fences of large-scale sites. It has excellent protection against rock fall, debris flow, avalanche protection and shallow slope disasters.

      Falling stone protective mesh specific installation steps:

      Put the falling stone protection mesh on the surface of the slope body or hang it upright on the hillside, taking into account the height and steepness of the slope. The placement of the falling stone protective mesh needs to be determined according to different locations. The installation of the falling stone protective mesh can be divided into four steps.

      1. According to the actual situation, deal with the surface of the slope (to remove loose debris, weeds and other debris).

      2. Unwind the falling rock protection net from the top of the slope; this step is also the most difficult to operate. Can be divided into two kinds of operation methods:

      The first method is to transport the rolled nets to the top of the slope body. After aligning and aligning, the net is unfolded and fixed on the edge of the uphill slope. The net is free to fall. This method is applicable to roads leading to the top of the mountain, where there are telephone lines, telephone poles, railways and other public facilities.

      The second method is to deploy the falling stone protective mesh at the bottom of the slope, and use a hook to lift the net to a designated place and fix it. This requires a hoist or a crane. The use of hoists or cranes has operational limitations such as traffic jams and restrictions on construction space when the highway is narrow. In order to overcome the above restrictions, helicopters are also used to speed up the operation. When the slope is higher than 25m, the helicopter is the best tool.

      3. Fix the falling stone protective mesh to the wall or the slope body.

      4. Finally, fix the top and bottom of the slope surface net.
