A new type of active slope protection system

Abstract

This utility model discloses a novel active slope protection system, comprising multiple support ropes and reinforcing components. The support ropes are arranged laterally and longitudinally along the slope to form multiple grid areas. Each grid area is equipped with a protective net, which is connected to the support ropes around the grid area. The reinforcing components are installed in the grid areas where there is a cavity between the protective net and the unstable rock mass. These components strengthen the protective net in their respective grid areas and reduce the distance between the net and the rock wall. In this utility model, when a cavity exists between a section of the protective net and the unstable rock mass, a reinforcing component is installed in the grid area containing that net. This reinforces the net in that grid area, reduces the distance between the net and the rock wall, decreases the initial velocity of falling rocks, reduces damage to the protective net, and ensures the safety of the slope engineering.

Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a novel active slope protection system. Background Technology

[0002] Currently, the natural slopes on both sides of the hydropower station project are steep, with strong shallow unloading and loose rock mass. This is especially true for ridges, gullies, and high-elevation slopes with open sides on three sides, where rock mass unloading and loosening are even more pronounced. Furthermore, the rock mass is cut by structural planes, creating unfavorable combinations on the slope surface. Under long-term weathering and unloading effects, many unstable rock masses and blocks are formed. The main protective measure for small rocks is currently the deployment of active protective nets to prevent accidental rolling. However, because the unstable rock mass is cut by fissures, cavities may form in some areas. The current active protective nets are deployed in a planar manner around the unstable rock mass, and these "cavities" are not tightly attached to the rock wall. When a rock mass falls, the active protective net is subjected to a greater impact force because it is not tightly attached to the rock wall. This increased speed of the falling rock mass due to the lack of tight attachment to the rock wall increases the bending moment on the active protective net, making it prone to breakage and subsequent rock mass collapse, potentially causing casualties and other accidents. Utility Model Content

[0034] Please refer to Figures 1 to 5 This application provides a novel active slope protection system, comprising multiple support ropes 1 and reinforcement components. The multiple support ropes 1 are arranged laterally and longitudinally along the slope to form multiple grid areas. Each grid area is equipped with a protective net 2, and the protective net 2 is connected to the support ropes 1 around the grid area. The reinforcement components are set in the grid areas where there is a cavity between the protective net 2 and the unstable rock mass, and are used to strengthen the protective net 2 in the grid area and reduce the distance between the protective net 2 and the rock wall.

[0035] In this application, multiple support ropes 1 are arranged laterally and longitudinally along the slope to form multiple grid areas, with the support ropes 1 fixed to the slope surface at the intersection of the laterally and longitudinally directions. Each grid area is equipped with a protective net 2, and the protective net 2 is fixedly connected to the support ropes 1 around the perimeter of the grid area. By covering and wrapping the slope or rock to be protected with the protective net 2, the weathering and erosion or damage of the slope rock and soil and the collapse of dangerous rocks are restricted, and falling rocks are controlled within a certain range of movement.

[0036] Because the unstable rock mass is cut by fissures, cavities may form in some areas. However, the aforementioned protective net 2 is laid out in a plane. In the local "cavity" locations, it cannot be tightly attached to the rock wall. When the unstable rock mass falls, the protective net 2 is subjected to a large impact force from the falling block, which can easily cause the protective net 2 to break, the unstable rock mass to fall, and cause accidents such as casualties.

[0037] In this application, when there is a cavity between a protective net 2 and the unstable rock mass, a reinforcing component is installed in the grid area where the protective net 2 is located. The reinforcing component is used to strengthen the protective net 2 in the grid area and reduce the distance between the protective net 2 and the rock wall, thereby reducing the initial velocity of the falling rock mass, reducing the damage to the protective net 2, ensuring the safety of the slope engineering, and reducing the occurrence of safety accidents.

[0038] According to some embodiments of this application, the reinforcing components include transverse reinforcing ropes 3 and longitudinal reinforcing ropes 4, which are woven into the protective netting 2 along the transverse and longitudinal directions, respectively, and their ends are connected to the support ropes 1 around the perimeter of the grid area. By setting the transverse reinforcing ropes 3 and longitudinal reinforcing ropes 4, the supporting force of the protective netting 2 can be increased, preventing the large impact force of falling rocks from breaking through the protective netting 2.

[0039] Specifically, the transverse reinforcing ropes 3 are alternately woven into the mesh of the protective netting 2 from both sides in the transverse direction, and both ends of the transverse reinforcing ropes 3 are fixedly connected to the support ropes 1 on both sides of the mesh area. Similarly, the longitudinal reinforcing ropes 4 are alternately woven into the mesh of the protective netting 2 from both sides in the longitudinal direction, and both ends of the longitudinal reinforcing ropes 4 are fixedly connected to the support ropes 1 on both sides of the mesh area. This allows the transverse reinforcing ropes 3 and the longitudinal reinforcing ropes 4 to be better restrained on the protective netting 2.

[0040] According to some embodiments of this application, the reinforcement components further include a fixing rod 5, a fixing pad 6, a fixing pressure plate 7, and a fixing nut 8. The fixing rod 5 is anchored to the slope, the fixing pad 6 is disposed on the fixing rod 5 and located below the protective netting 2, the fixing pressure plate 7 is sleeved on the fixing rod 5 and located above the protective netting 2, and the fixing nut 8 cooperates with the fixing rod 5 to press tightly against the fixing pressure plate 7. By setting the fixing rod 5, fixing pad 6, fixing pressure plate 7, and fixing nut 8, the distance between the protective netting 2 and the rock wall can be reduced, the initial velocity of the falling rock mass can be reduced, and the damage to the protective netting 2 can be minimized.

[0041] The aforementioned fixing rod 5 is anchored to the slope. The fixing pad 6 is pre-installed on the fixing rod 5. Then, the protective netting 2 is laid, with the upper end of the fixing rod 5 passing through the mesh of the protective netting 2. Next, the fixing pressure plate 7 is fitted onto the fixing rod 5, and a fixing nut 8 is screwed into the fixing rod 5. The fixing nut 8 is used to clamp the protective netting 2 between the fixing pressure plate 7 and the fixing pad 6. Only the distance between the fixing pad 6 and the rock wall needs to be pre-set.

[0042] According to some embodiments of this application, the center of the fixing pad 6 and the fixing pressure plate 7 is provided with an installation hole 9 that is adapted to the fixing rod 5. The fixing pad 6 is provided with a plurality of limiting holes 61, and the fixing pressure plate 7 is provided with a plurality of limiting rods 71, which cooperate with the limiting holes 61.

[0043] Since the fixing rod 5 is inserted into the mounting holes 9 of the fixing pad 6 and the fixing pressure plate 7, by setting the limiting rod 71 and the limiting hole 61, when the fixing pressure plate 7 is installed, each limiting rod 71 is inserted into the corresponding limiting hole 61. This not only prevents the fixing pressure plate 7 from rotating, but also the area between each limiting rod 71 and the fixing rod 5 can play a certain limiting role for the protective net 2, the transverse reinforcing rope 3 and the longitudinal reinforcing rope 4.

[0044] According to some embodiments of this application, the plurality of limiting holes 61 and the plurality of limiting rods 71 ​​are all evenly distributed circumferentially around the mounting hole 9. In this example, four limiting holes 61 and four limiting rods 71 ​​are provided.

[0045] According to some embodiments of this application, the multiple support ropes 1 are fixed to the slope surface by anchor rods 10 at the intersection of the transverse and longitudinal directions.

[0046] Specifically, after clearing the slope protection area, the anchor bolt 10 hole positions are determined by marking lines. A pit with a depth not less than the length of the exposed ring 101 of the anchor bolt 10 is chiseled at each hole position. Anchor bolt 10 holes are then drilled and cleaned according to their length. The anchor bolt 10 is then inserted into the holes and grout is injected. After the grout solidifies, the anchor bolt 10 is fixed to the slope. After the anchor bolt 10 is fixed, longitudinal and transverse support ropes 1 are installed. The support ropes 1 are threaded through the ring 101 of the anchor bolt 10, and both ends of the support ropes are bent in the opposite direction and secured with rope clamps.

[0047] According to some embodiments of this application, the protective net 2 is fixedly connected to the support ropes 1 around the perimeter of the mesh area by stitching lines 11. Specifically, the stitching lines 11 can be made of iron wire.

[0048] According to some embodiments of this application, the protective net 2 includes overlapping steel rope nets and grid nets. By using overlapping steel rope nets and grid nets in this application, not only is good flexibility and impact resistance achieved, but the interception rate of small-sized falling rocks by the protective net 2 can also be improved.

[0049] According to some embodiments of this application, the two ends of the transverse reinforcing rope 3 and the longitudinal reinforcing rope 4 are fixedly connected to the support rope 1 around the grid area by rope clips.

[0050] According to some embodiments of this application, the transverse reinforcing rope 3 and the longitudinal reinforcing rope 4 are steel ropes.

[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
