Slope protection device

Abstract

The invention discloses a side slope protecting device which comprises a blocking wall and a damping device, wherein the cross section of the blocking wall is in an L shape, and the damping device is arranged on the rear side of the blocking wall. In the process that the blocking wall is impacted by landslide sand and gravels and accordingly slides backwards, the damping device is used for supporting the blocking wall forwards and providing damping force. By arranging the blocking wall capable of sliding at the slope toe, when the slope surface slips, the falling sand and gravels impact on the blocking wall, so that the blocking wall slides backwards under the damping force of the damping device, the impact force of the falling sand and gravels on the blocking wall can be greatly reduced, the effect that the blocking wall is subjected to uniform and small impact force is guaranteed, damage of the blocking wall is avoided, the effect that the falling sand and gravels are effectively blocked is guaranteed, and the safety of the road surface is improved. Meanwhile, the construction area of the blocking wall is small, the damping device can be directly placed and installed after the finished damping device is manufactured, the installation period and construction period are short, the cost is low, the structure is simple, and installation is easy.

Description

technical field [0001] The invention relates to the field of slope management, in particular to a slope protection device. Background technique [0002] Slope generally refers to the side of a mountain with an inclined slope surface. Due to the inclination of the slope surface, it is easy to lose stability and landslide under the action of the slope's own gravity and other external forces, especially under the action of rainfall erosion. The trend of low sliding, in the prior art, the slope surface is generally reinforced by lattice reinforcement; the lattice reinforcement technology is to use mortar block stone, cast-in-place reinforced concrete or prefabricated prestressed concrete to protect the slope surface , and use anchor rods or anchor cables to fix a slope reinforcement technology, or use the method of building retaining walls along the side of the slope body, the main function is to distribute the remaining sliding force or earth pressure and rock pressure of the s...

[0002] Slope generally refers to the side of a mountain with an inclined slope surface. Due to the inclination of the slope surface, it is easy to lose stability and landslide under the action of the slope's own gravity and other external forces, especially under the action of rainfall erosion. The trend of low sliding, in the prior art, the slope surface is generally reinforced by lattice reinforcement; the lattice reinforcement technology is to use mortar block stone, cast-in-place reinforced concrete or prefabricated prestressed concrete to protect the slope surface , and use anchor rods or anchor cables to fix a slope reinforcement technology, or use the method of building retaining walls along the side of the slope body, the main function is to distribute the remaining sliding force or earth pressure and rock pressure of the slope body The anchor rod or anchor cable at the lattice node is then transmitted to the stable stratum through the anchor cable, so that the slope body is in a stable state under the action of the anchor force provided by the anchor rod or anchor cable, and then the slope The landslide will cause safety hazards to the road below; and because of the need to reinforce the slope by building lattice or retaining wall, the general slope area is relatively large, resulting in the need for a lot of labor and materials, and the amount of work is large. For steeper slopes, the construction is more difficult, resulting in higher cost in the slope treatment process, and the slopes that have been landslides need to be reinforced again to ensure the safety of the reinforcement; and these need to be repeated Reinforcement and engineering volume both increase the cost of slope reinforcement and maintenance. If a protective wall is directly built at the foot of the slope to stop the landslide, the sand and gravel of the landslide have a certain inertia during the sliding process, which will cause a great impact on the protective wall, resulting in The protective wall is damaged and the purpose of protection is lost
