First, find an 8-ton iron block and throw it from a height of 30 meters. After winding, the rockfall protection net composed of steel wire rope nets is blocked. It can be seen whether the rockfall protection net can provide effective protection for some irregular natural disasters. The test results show that although the protective net has a certain deformation, it can still prevent the falling iron blocks from falling from high altitude. The success of the inspection has also dispelled many people's fears, and this inspection can also provide some useful data for some projects.

At the same time, some problems should be paid attention to when using flexible rockfall protection net equipment: the rockfall protection net is composed of multiple parts, mainly including support ropes, wire rope nets and bolts. During the use of the equipment, the following points need to be paid attention to: the gap between the top and the support rope is generally 4.5 meters, and the steel wire rope net is generally a 4-meter-long square. On the equipment, it is necessary to set a certain interval between the wire rope net and the support rope for sewing. Anchor rods are required to secure the longitudinal and lateral support ropes. Sand blocking nets are mainly distributed in the center of mountainous areas and wire rope nets, so planning for fixing small falling rocks is the most useful.
