Mountain landslide defending system

Abstract

The invention discloses a mountain landslide defending system which comprises a blocking wall with the L-shaped cross section, a sliding limiting groove formed in the front-back direction for left-right limiting of the blocking wall, and damping devices arranged on the rear side of the blocking wall. When the blocking wall is impacted by landslide gravels to slide backwards, the damping devices are used for forwards supporting the blocking wall and provides damping force. The slidable blocking wall is arranged at the slope toe, when a slope landslides, the sliding gravels impact the blocking wall, and the blocking wall is made to slide backwards under the damping force of the damping devices; and accordingly the impact force of the falling gravels on the blocking wall can be greatly reduced, it is guaranteed that the blocking wall bears small uniform impact force and is prevented from being damaged, effective blocking of the falling gravels is guaranteed, and the safety of a road surface is improved. Meanwhile, the construction area of the blocking wall is small, the finished blocking wall can be directly installed and then provided with the damping devices, the installation construction period is 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 control, in particular to a landslide defense system. 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 slo...

[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
