Technical Field
[0001] The utility model relates to the technical field of mountain slope protection nets, in particular to a mountain slope anti-rockfall protection net. Background Art
[0002] On rocky slopes, falling rocks often occur due to weathering, rain or vibration. In order to prevent falling rocks from injuring pedestrians, the slopes need to be protected. This requires the use of protective nets. When falling rocks fall, the protective nets will block them, greatly improving safety.
[0003] Common mountain slope rockfall protection nets only have a protective function and can block falling rocks, but lack the function of increasing the strength of the net. It cannot guarantee that the net will not break due to the impact of falling rocks, resulting in protection failure. It is easy for falling rocks to fall too fast or be too heavy, resulting in excessive impact force, which will cause the net to break when it hits the net. In this way, the falling rocks will continue to fall down, affecting the safety of protection.
[0004] Therefore, in view of the fact that the above-mentioned mountain slope anti-fall rock protection net lacks the function of improving the strength of the protection net, a mountain slope anti-fall rock protection net can be designed. By setting up a slope protection net to block falling rocks, when falling rocks hit the slope protection net, a protection ring net composed of several circular steel rings will support the slope protection net, thereby preventing the slope protection net from being broken due to excessive force. When the slope protection net is scratched by sharp objects, the protection ring net can prevent larger falling rocks from continuing to fall, ensuring that the protection net will not break due to the impact force of falling rocks, resulting in protection failure. Utility Model Content
[0005] In order to overcome the common mountain slope anti-fall rock protection net, the function of improving the strength of the protection net is lacking. It cannot guarantee that the protection net will not break due to the impact of falling rocks, resulting in protection failure. It is easy for the falling rocks to fall too fast or be too heavy, resulting in excessive impact force, which will cause the protection net to break when hitting it. In this way, the falling rocks will continue to fall down, affecting the safety of protection.
[0006] The technical solution of the utility model is: a mountain slope anti-rockfall protection net, including a protection ring edge; also including a slope protection net, a protection ring net, a connecting ring, an H-shaped steel column and a fixing piece, the inner side of the protection ring edge is provided with a slope protection net, the rear side of the slope protection net is provided with a protection ring net, the upper and lower sides of the protection ring edge are provided with a number of connecting rings at equal intervals, the protection ring edge is connected to the protection ring net through the connecting ring, two H-shaped steel columns are symmetrically provided at the left and right ends of the rear side of the protection ring edge, and three fixing pieces are provided at equal intervals on the front side of the H-shaped steel column corresponding to the position of the protection ring edge.
[0007] Preferably, a slope guard net is set up to block falling rocks. When falling rocks hit the slope guard net, a protective ring net composed of several circular steel rings put together will support the slope guard net, thereby preventing the slope guard net from being broken by excessive force. When the slope guard net is scratched by a sharp object, the protective ring net can prevent larger falling rocks from continuing to fall, ensuring that the guard net will not break due to the impact force of falling rocks, resulting in protection failure. This solves the problem that the common mountain slope anti-falling rock protection net only includes a protection function and can block falling rocks, but lacks the function of increasing the strength of the guard net, and cannot ensure that the guard net will not break due to the impact force of falling rocks, resulting in protection failure. It is easy for falling rocks to fall too fast or be too heavy, resulting in excessive impact force, which will cause the guard net to break when hitting the guard net. In this way, the falling rocks will continue to fall, affecting the protection safety.
[0008] Preferably, two connection holes are symmetrically opened at the left and right ends of the front side of the fixing piece, and six fixing holes are opened at equal intervals at the positions corresponding to the connection holes on the front side of the H-shaped steel column.
[0009] Preferably, the fixing piece is connected to the H-shaped steel column by passing a bolt through the connection hole and then screwing into the interior of the fixing hole.
[0010] Preferably, a ground nail is provided at the center of the bottom of the H-shaped steel column, and a plurality of anti-slip rings are provided at equal intervals around the ground nail.
[0011] Preferably, a reinforcement block is provided in the middle of the top of the H-shaped steel column, and four mounting holes are provided at equal intervals through the four corners of the top of the reinforcement block.

[0013] Preferably, the slope protection net is composed of a plurality of steel wires woven together, and the protection ring net is composed of a plurality of circular steel rings looped together.
[0014] Beneficial effects of the utility model:
[0015] 1. Rockfall is blocked by setting up a slope guard net. When the rockfall hits the slope guard net, a guard ring net composed of several circular steel rings will support the slope guard net, thereby preventing the slope guard net from being broken due to excessive force. When the slope guard net is scratched by a sharp object, the guard ring net can prevent larger rocks from continuing to fall, ensuring that the guard net will not break due to the impact force of the rockfall, resulting in protection failure. This solves the problem that the common mountain slope rockfall protection net only includes a protection function and can block rockfall, but lacks the function of increasing the strength of the guard net. It cannot ensure that the guard net will not break due to the impact force of the rockfall, resulting in protection failure. It is easy for the rockfall to fall too fast or be too heavy, resulting in excessive impact force and breaking when it hits the guard net. In this way, the rockfall will continue to fall, affecting the safety of protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figures 1-4The utility model provides an embodiment: a mountain slope anti-rockfall protection net, including a protection ring edge 1; it also includes a slope protection net 2, a protection ring net 3, a connecting ring 4, an H-shaped steel column 5 and a fixing piece 6. The inner side of the protection ring edge 1 is provided with a slope protection net 2, and the rear side of the slope protection net 2 is provided with a protection ring net 3. The upper and lower sides of the protection ring edge 1 are equidistantly provided with a plurality of connecting rings 4. The protection ring edge 1 is connected to the protection ring net 3 through the connecting ring 4. Two H-shaped steel columns 5 are symmetrically provided at the left and right ends of the rear side of the protection ring edge 1, and three fixing pieces 6 are equidistantly provided at the front side of the H-shaped steel column 5 corresponding to the position of the protection ring edge 1. The slope protection net 2 is provided to block falling rocks. When falling rocks hit the slope protection net 2, several circular steel The protective ring net 3 composed of rings put together will support the slope protection net 2, thereby preventing the slope protection net 2 from being broken by excessive force. When the slope protection net 2 is scratched by sharp objects, the protective ring net 3 can prevent larger rocks from continuing to fall, ensuring that the protection net will not be broken due to the impact force of the falling rocks, resulting in protection failure. This solves the problem that the common mountain slope anti-rockfall protection net only includes protection functions and can block falling rocks, but lacks the function of increasing the strength of the protection net. It cannot ensure that the protection net will not be broken due to the impact force of falling rocks, resulting in protection failure. It is easy for falling rocks to fall too fast or be too heavy, resulting in excessive impact force, which will cause the protection net to break when it hits the protection net. In this way, the falling rocks will continue to fall down, affecting the protection safety.
[0023] See also Figure 2-Figure 4 In this embodiment, a ground nail 9 is provided at the center of the bottom of the H-shaped steel column 5, and a number of anti-slip rings 10 are provided at equal intervals around the ground nail 9. A reinforcement block 11 is provided in the middle of the top of the H-shaped steel column 5. Four mounting holes 12 are provided at equal intervals at the four corners of the top of the reinforcement block 11. Two pull ropes 13 are symmetrically set on the two mounting holes 12 on the rear side of the reinforcement block 11. The pull rope 13 is composed of several steel wires wrapped together. The ground nail 9 is inserted into the ground. When the ground nail 9 is loose, its position is limited by the anti-slip ring 10 to prevent the ground nail 9 from moving upward and thus falling off the ground. After the ground nail 9 is inserted into the ground, the end of the pull rope 13 away from the reinforcement block 11 is fixed to a nearby tree trunk to reinforce the H-shaped steel column 5.
[0024] See also Figures 1-4In this embodiment, two connecting holes 8 are symmetrically opened at the left and right ends of the front side of the fixing member 6, and six fixing holes 7 are opened at equal intervals on the front side of the H-shaped steel column 5 at positions corresponding to the connecting holes 8. The fixing member 6 is screwed into the interior of the fixing holes 7 and connected to the H-shaped steel column 5 after passing through the connecting holes 8 by bolts. The slope protection net 2 is composed of several steel wires woven together, and the protective ring net 3 is composed of several circular steel rings sleeved together. The slope protection net 2 is set to block falling rocks. When the falling rocks hit the slope protection net 2, the several circular steel rings are used to prevent the falling rocks from hitting the slope protection net 2. The protective ring net 3 formed together will support the slope protection net 2, thereby preventing the slope protection net 2 from being broken due to excessive force. When the slope protection net 2 is scratched by a sharp object, the protective ring net 3 can prevent larger rocks from continuing to fall, ensuring that the protection net will not be broken due to the impact force of the falling rocks, resulting in protection failure, thereby achieving the function of improving the strength of the protection net, preventing the falling rocks from falling too fast or being too heavy, resulting in excessive impact force and causing the protection net to break when hitting the protection net, so that the falling rocks will continue to fall downward, affecting the protection safety.
[0025] During work, the ground nail 9 is inserted into the ground. When the ground nail 9 is loose, its position is limited by the anti-slip ring 10 to prevent the ground nail 9 from moving upward and thus falling off the ground. After the ground nail 9 is inserted into the ground, the end of the pull rope 13 away from the reinforcement block 11 is fixed to a nearby tree trunk to reinforce the H-shaped steel column 5. The falling rocks are blocked by setting the slope protection net 2. When the falling rocks hit the slope protection net 2, the protection ring net 3 composed of several circular steel rings will support the slope protection net 2, thereby preventing the slope protection net 2 from being broken due to excessive force. When the slope protection net 2 is scratched by a sharp object, the protection ring net 3 can prevent larger falling rocks from continuing to fall, ensuring that the protection net will not break due to the impact force of the falling rocks, resulting in protection failure, thereby achieving the function of improving the strength of the protection net.
[0026] The above steps are used to block falling rocks by setting up the slope protection net 2. When the falling rocks hit the slope protection net 2, the protection ring net 3 composed of several circular steel rings will support the slope protection net 2, thereby preventing the slope protection net 2 from being broken by excessive force. When the slope protection net 2 is scratched by a sharp object, the protection ring net 3 can prevent larger falling rocks from continuing to fall, ensuring that the protection net will not break due to the impact force of the falling rocks, resulting in protection failure, so as to solve the problem that the common mountain slope anti-falling rock protection net only includes a protection function and can block falling rocks, but lacks the function of improving the strength of the protection net, and cannot ensure that the protection net will not break due to the impact force of falling rocks, resulting in protection failure. It is easy for the falling rocks to fall too fast or be too heavy, resulting in excessive impact force, which will cause the protection net to break when hitting the protection net. In this way, the falling rocks will continue to fall, affecting the protection safety.
