The invention relates to the field of side slope protection technologies, and in particular, to a combined type flexible glass net system used for protection against full-particle falling rocks on plank roads in scenic spots.
Plank roads in canyon-type and mountain-type scenic spots are often threatened by falling rocks, which not only hinder passage, but also seriously endanger lives of passing tourists. When colliding with the mountain, the falling rocks may break or cause a slope surface to break to form more rock masses with high energy and different shapes, thereby increasing the hazard of the failing rocks. Therefore, protection of falling rocks in scenic spots needs to consider interception and protection of full-size falling rocks. Plank roads in scenic spots are usually narrow and winding, and therefore, it is inconvenient to transport construction materials there and it is difficult to carry out large-scale construction operations. In addition, for the protection of falling rocks in scenic spots, construction of protective facilities adopted also needs to consider suitability of the human landscapes and integration of the ecological environment.
The traditional passive flexible protection net system, active net system, flexible shed hole or flexible canopy all use two layers of metal meshes with different pore sizes to intercept the falling rocks, which cannot solve the technical problem of interception and protection of full-size falling rocks, and lacks a landscape adaptation function. The small-size falling rocks penetrating through mesh holes often endanger lives of passing tourists, and affect the landscapes.
In view of this, persons skilled in the art devote to flexible falling rock protection facilities with suitability of the human landscapes and integration of the ecological environment, construction and maintenance convenience, and full-size falling rock protection performance.

When the system works, large-size falling rocks are in collision and contact with the metal meshes, so that the meshes are deformed; and meanwhile, impact force is transmitted onto the along-cross-slope connecting ropes, the reinforcing rope and the traction rope; impact force is transmitted to mountain support and the supporting layer structure through the along-cross-slope connecting ropes and the traction rope, and is transmitted to a base through the supporting layer structure; and energy stored in components is transmitted to the falling rocks at a restoration stage while the falling rocks are thrown out of the system to leave the protected area. In addition, if the falling rocks are in collision with the slope surface, the slope is driven to crush the rocks and roll, so that small-size stones possibly pass through the metal meshes and drop to the flexible glass net while the glass plates can block small-size stones, and thus, the falling rocks are ensured to be prevented from damaging vehicles and pedestrians on a road. Crushed stones on the flexible glass net can be cleared regularly.
The fixing way and the connecting way are the same as those in the prior art, which is not described in detail here.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, but not limited thereto.
