Description

Technical Field

[0001] This utility model relates to the field of slope protection, specifically a safety-type passive slope protection net. Background Technology

[0002] Slope collapses, landslides, rockfalls and other geological disasters are widespread in mountainous areas, roads, mines and building slopes, seriously threatening the safety of life and property and the stability of engineering facilities. Passive protection nets are interception systems set up below slopes or in potential disaster areas to buffer and intercept rolling rocks, soil and other debris.

[0003] Chinese Patent CN220644306U discloses a safe passive slope protection net, including fixed posts and fixed frames. The fixed posts have a fixed frame inside, and the fixed frames have a buffer net inside. The buffer net and the fixed frames are fixedly connected. The inner wall of the fixed posts has a groove, and the groove has a slider inside. The slider and the groove are slidably connected. A spring is provided on one side of the slider, and the spring and the slider are fixedly connected. Multiple buffer rings are provided on one side of the buffer net. While the buffer net, groove, slider, spring, and buffer rings are present, the aforementioned patent requires fixed posts to support the buffer net during installation. However, it is difficult to quickly and securely connect the connected buffer nets, thus failing to achieve the desired protective effect for the combined connection and reducing the slope protection effect. Therefore, we propose a safe passive slope protection net to solve the above problems. Utility Model Content

[0021] According to one embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.

[0022] A passive slope protection net includes two support bases 1, with a lower protective buffer net 2 between the two support bases 1. An upper buffer element 3 is hinged to the top of the lower protective buffer net 2 via a pin. Two concave sliding blocks 4 are fixedly installed on the outer surfaces of both support bases 1. Sliding plates 5 are slidably connected to the inner walls of both concave sliding blocks 4. Threaded grooves 8 are formed on the front sides of both sliding plates 5. Fixing screws 9 are provided on the front sides of both concave sliding blocks 4, and the outer surface of the fixing screws 9 is threaded to the inner wall of the threaded grooves 8. The support bases 1 serve as the basic support structure for the entire protection net, providing stability. The protective buffer net 2 serves as a support, intercepting and buffering rocks rolling down the slope. It absorbs the impact force through its own flexible deformation. The upper buffer 3 is hinged to the protective buffer net 2 via a pin. When rocks impact, it can work together with the protective buffer net 2 to buffer, enhancing the vertical protection capability. The upper and lower installation positions of the protective buffer net 2 can be adjusted by sliding the sliding plate 5 in the concave sliding seat 4. Furthermore, by screwing the fixing screw 9 into the threaded groove 8 of the sliding plate 5, the sliding plate 5 can be fixed in a suitable position, achieving stable installation and adjustment of the protective buffer net 2.

[0023] In this example, two connecting blocks 6 are fixedly connected to the sides of the two sliding plates 5 that are close to each other. The sides of the two sets of connecting blocks 6 that are close to each other are fixedly connected to the outer surface of the protective buffer net 2. The front of the two concave sliding blocks 4 are provided with strip holes 7, which are located in front of the two sets of threaded grooves 8 respectively. The top of the two support bases 1 are hinged to the side protective nets 12 by pins. The outer surface of the two side protective nets 12 is fixedly inlaid with first fixing rings 13. The sliding plates 5 and the protective buffer net 2 are connected by connecting blocks 6. This ensures that the sliding plate 5 moves synchronously with the lower protective buffer net 2 during adjustment, allowing the lower protective buffer net 2 to be stably installed between the support seats 1. The sliding plate 5 can be locked and fixed by the fixing screw 9 passing through the strip hole 7 and cooperating with the threaded groove 8. The side protective net 12 is hinged to the top of the support seat 1 by a pin and is used to protect against stones rolling down from above the support seat 1. Anchor rods 303 and other fixing parts can be inserted through the first fixing ring 13 to firmly fix the side protective net 12 to the side of the slope and enhance the stability of the side protective net 12.

[0024] In this example, the upper buffer 3 includes a protective buffer net 301. Two second fixing rings 302 are fixedly embedded in the outer surface of the protective buffer net 301. Anchor rods 303 are provided inside each of the two second fixing rings 302. Fixed base plates 10 are fixedly connected to the bottom ends of both support seats 1. Two fixing holes 11 are opened on the bottom surface of each of the two fixed base plates 10. Both the lower protective buffer net 2 and the upper protective buffer net 301 are woven from high-strength steel wire rope. The outer surfaces of both the lower protective buffer net 2 and the upper protective buffer net 301 are coated with a zinc-aluminum alloy. Reinforcing ropes 14 are fixedly connected to the outer surface of the side protective net 12. The diameter of the reinforcing ropes 14 is 1.5 times the diameter of the side protective net 12. The protective buffer net 301 is the main component of the upper buffer 3, forming a double-layer buffer with the lower protective buffer net 2. The structure further enhances the buffering and interception effect against rocks. Anchor bolts 303 pass through the second fixing ring 302 and can be fixed to the slope rock mass. The protective buffer net 301 can be firmly installed on the slope to ensure its stability during protection. Anchor bolts and other connectors can be inserted through the fixing base plate 10 and fixing holes 11 to firmly fix the support base 1 to the slope ground, enhancing the basic stability of the entire protective net. The lower protective buffer net 2, the upper protective buffer net 301, and the side protective net 12 are all woven with high-strength steel wire rope, giving them high strength and toughness to withstand the impact of rocks. The zinc-aluminum alloy coating can improve the corrosion resistance of the protective net and extend its service life. The reinforcing rope 14 can enhance the strength and tear resistance of the side protective net 12, improving the protective performance of the side protective net 12 against rocks.

[0025] Working principle: First, by inserting anchor bolts or anchor rods 303 into the fixed base plate 10 and fixed holes 11, the support base 1 can be firmly fixed in the slope rock or soil layer, providing vertical support force. Then, the protective buffer net 2 is installed horizontally between the two support bases 1. The sliding plate 5 is driven to slide downward inside the concave sliding seat 4 by the connecting blocks 6 on both sides. By adjusting its position, the position between the protective buffer net 2 and the concave sliding seat 4 is adjusted. Then, the fixing screw 9 passes through the strip hole 7 of the concave sliding seat 4 and is screwed into the threaded groove 8 of the sliding plate 5, which can lock the sliding plate 5 in the target position, realizing the rapid positioning and firm connection of the protective buffer net 2.

[0026] Next, the upper buffer 3 is fixed to the rock mass above the slope by the second fixing ring 302 and the anchor rod 303, while the side protection net 12 is fixed by inserting the first fixing ring 13 into the anchor rod 303, thus forming a two-layer buffer structure to improve the vertical interception capability of falling rocks.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
