Description

Technical Field

[0001] This utility model relates to a landslide and rockfall protection device, belonging to the technical field of geological disaster prevention and control equipment. Background Technology

[0002] Landslides and rockfalls are frequent geological disasters in mountainous areas, often threatening people's lives and property. Countries around the world are paying more and more attention to the prevention and control of geological disasters. Engineering prevention and control measures for landslides and rockfalls usually include: removing dangerous rock masses, active protection nets, passive protection nets, and anchor reinforcement.

[0003] Removal of unstable rock masses: This method involves using manual or mechanical equipment to blast or mechanically remove unstable rock masses on steep cliffs. It is suitable for situations where the mountain is relatively low and there are no large numbers of residents living below the mountain. However, the removal process poses a significant threat to the personal safety of the personnel involved, and this method has considerable limitations and drawbacks.

[0004] Active protective netting: This method mainly involves hanging protective netting on the surface of unstable rock masses to prevent small rocks from falling. It is suitable for situations where the unstable rock mass is small in scale, with sporadic rockfalls, and the mountain is relatively low and easy to implement. However, it has very little effect on larger unstable rock masses and carries a high risk of implementation.

[0005] Passive protective netting: This method involves setting up a row of protective netting at the foot of the slope below the mountain, mainly to intercept falling rocks from above. This method is effective in intercepting smaller falling rocks. In practice, larger falling rocks often penetrate and damage the passive protective netting. Therefore, this method is basically ineffective in intercepting larger falling rocks.

[0006] Anchor bolt reinforcement: This method involves driving anchor bolts into the surface of the unstable rock mass to reinforce it. This method is suitable for relatively intact and hard unstable rock masses, but it is not suitable for reinforcing more broken or soft unstable rock masses.

[0007] The aforementioned traditional landslide and rockfall protection and control measures all have various limitations and drawbacks, resulting in unsatisfactory control effects, high construction risks, and excessively high control costs. Therefore, the demand for feasible and economical prevention and control methods or devices is more urgent. Summary of the Invention

[0008] The purpose of this invention is to provide a landslide and rockfall protection device. This invention is simple to install, economical, and has good protective and control effects, and can be widely applied to the prevention and control of various landslide and rockfall geological disasters.

[0009] The technical solution of this utility model is as follows: A landslide and rockfall protection device includes an arc-shaped metal plate with the opening of the metal plate facing the mountain. A rubber pad layer is fixed on the inner surface of the metal plate. The rubber pad layer is fixed to the ground by anchors and the front edge of the metal plate. The outer side of the metal plate is supported and reinforced by support columns.

[0010] In the aforementioned landslide and rockfall protection device, the rubber pad layer is bonded and fixed to the inner surface of the metal plate.

[0011] In the aforementioned landslide and rockfall protection device, the anchors are arranged in multiple rows at intervals, each row consisting of several anchors arranged at intervals. The anchors pass through the rubber pad layer and the metal plate and then fix them to the ground.

[0012] In the aforementioned landslide and rockfall protection device, the metal plate is composed of multiple vertically arranged metal plates spliced ​​together. Each metal plate has a groove on one side and a protrusion on the other side, and two metal plates are spliced ​​together by the groove and the protrusion.

[0013] In the aforementioned landslide and rockfall protection device, each metal plate has at least one row of anchor holes, and its back is supported and reinforced by at least one support column.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model, due to its combined structure of rubber pad, metal plate, groove, support column, anchor, and protrusion, enables the protective device to successfully intercept large-scale and high-kinetic-energy rockfalls through impact energy dissipation and rolling energy dissipation. Furthermore, the protective device is not easily damaged by rolling rocks. This utility model is simple to install, economical, and has good protective and mitigation effects, making it widely applicable to the prevention and control of various types of landslide and rockfall geological disasters.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] An embodiment of this utility model: a landslide and rockfall protection device, such as... Figure 1-5 As shown, the metal plate 2 includes an arc-shaped structure with its opening facing the mountain. A rubber pad layer 1 is fixed to the inner surface of the metal plate 2. The rubber pad layer 1 and the front edge of the metal plate 2 are fixed to the ground by anchor nails 5. The outer middle part of the metal plate 2 is supported and reinforced by a support column 4.

[0023] The adhesive pad 1 is fixed to the inner surface of the metal plate 2 by bonding.

[0024] The anchors 5 are arranged in multiple rows at intervals, and each row consists of several anchors 5 arranged at intervals. After passing through the rubber pad layer 1 and the metal plate 2, the anchors 5 are fixed to the ground. The protective device can be well fixed by multiple rows of anchors 5.

[0025] The metal plate 2 is composed of multiple vertically arranged metal plates spliced ​​together. Each metal plate has a groove 3 on one side and a protrusion 6 on the other side. Two metal plates are spliced ​​together by the groove 3 and the protrusion 6. This structure facilitates the splicing of the metal plates 2, and the metal plates 2 can be spliced ​​into different widths according to the area that needs to be protected.

[0026] Each metal plate has at least one row of anchor holes for easy insertion of anchors 5, which can also be used to fix each metal plate in place. Similarly, each metal plate has at least one support column 4 on its back for support and reinforcement, ensuring that each metal plate is reinforced.

[0027] This utility model's landslide and rockfall protection device consists of multiple arc-shaped metal plates 2 joined together by protrusions 6 and grooves 3 on the sides. Anchor nails 5 are used to fix the metal plates 2 and the rubber pad layer 1 to the ground below the mountain. Support columns 4 are used to support and reinforce the outer side of the metal plates 2. When a dangerous rock collapses and falls from above the mountain and hits the rubber pad layer 1 on the inner side of the metal plates 2, the falling rock will be dissipated for the first time. As the falling rock rolls upward with the rubber pad layer 1 on the inner side of the arc-shaped metal plates 2, the falling rock will be dissipated again. Finally, the falling rock will be successfully intercepted in front of the rubber pad layer 1.
