Description

Technical Field

[0001] This utility model belongs to the technical field of slope protection devices, and in particular relates to a slope protection device for highway engineering. Background Technology

[0002] In highway engineering, the design of slope protection devices needs to take into account terrain stability, soil and water conservation, ecological and environmental protection, and construction feasibility.

[0003] Existing slope protection types include rigid slope protection, flexible slope protection, and ecological slope protection, among which ecological slope protection is the most common. It forms a vegetation network through porous or honeycomb concrete structures, serving both landscaping and soil stabilization functions. However, the soil shoulders on both sides of highways become compacted due to construction rolling or vehicle pressure, resulting in poor water permeability and air permeability, making it difficult for plant roots to grow and affecting the coverage of the vegetation network. Utility Model Content

[0004] The technical problem this invention aims to solve is soil and water conservation on the earthen shoulders of highways, improving the coverage quality of vegetation nets, and preventing gravel from rolling.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a highway engineering slope protection device, including a connecting plate with through holes on both sides, and further including two expansion frames, an adjustment and limiting component, a protective net, and a positioning component. The two expansion frames are hinged to the bottom of the side wall of the connecting plate. The protective net is movably connected to the inner side of the expansion frame through the adjustment and limiting component. The adjustment and limiting component is slidably disposed on the outer wall of the expansion frame. The positioning component passes through the connecting plate and is movably connected to the middle of the connecting plate, and is used for fixing the position of the connecting plate and adjusting the angle of the symmetrical expansion frames.

[0006] Furthermore, the expansion frame is arranged in an n-shape, and the opening ends of the symmetrical expansion frames are bent in opposite directions.

[0007] Furthermore, the adjusting limiting assembly includes a sliding sleeve and a limiting screw. The sliding sleeve is slidably connected to the parallel outer wall of the expansion frame, the protective net is fixedly connected between the symmetrical outer walls of the sliding sleeve, and the limiting screw passes through the sliding sleeve and is threaded to the side wall of the sliding sleeve for fixing the position of the sliding sleeve.

[0008] Furthermore, the protective net has a partition on the side wall away from the connecting plate. The partitions are arranged at uniform intervals along the length of the expansion frame, and an implantation cavity is formed between adjacent partitions.

[0009] Furthermore, the positioning component includes a positioning frame and a stud. The positioning frame passes through the connecting plate and is slidably disposed within the connecting plate. The stud is rotatably connected to the middle of the upper wall of the connecting plate. The stud extends through the positioning frame to the upper part of the positioning frame. The stud is threadedly connected to the positioning frame. The through end of the stud is provided with a handle.

[0010] Furthermore, the positioning frame is arranged in an n-shape, and a rod is fixedly connected to the bottom end of the positioning frame. The rods are arranged symmetrically in pairs.

[0011] After adopting the above structure, the beneficial effects of this utility model are as follows: For soil and water conservation on both sides of the road shoulder, the positioning component is inserted into the shoulder, and the symmetrical expansion frame is unfolded close to the shoulder surface. Stones are filled into the shoulder surface and the bottom of the guard net to prevent soil and water from sliding downward, thus stabilizing the soil and stones of the shoulder.

[0012] Meanwhile, the protective net can slide along the length of the expansion frame, bringing the net closer to the opening of the expansion frame and allowing one end to adhere to the road shoulder surface, blocking the soil flow caused by rainwater erosion. Plants with well-developed root systems can be planted between the partitions at the top of the protective net, allowing the roots to penetrate the net and enter the limiting cavity and the soil shoulder, achieving vegetation net coverage and increasing the fixing effect between the device and the soil shoulder.

[0020] like Figure 1-5As shown, a highway engineering slope protection device includes a connecting plate 1 with through holes 2 on both sides for easy gripping and pressing. It also includes two expansion frames 3, an adjusting and limiting component 4, a protective net 5, and a positioning component 6. The two expansion frames 3 are hinged to the bottom of the side wall of the connecting plate 1. The protective net 5 is movably connected to the inner side of the expansion frames 3 via the adjusting and limiting component 4, which is slidably located on the outer wall of the expansion frames 3. The positioning component 6 penetrates the connecting plate 1 and is movably connected to the middle of the connecting plate 1, used for fixing the position of the connecting plate 1 and adjusting the angle of the symmetrical expansion frames 3. The expansion frames 3 are n-shaped, with the openings of the symmetrical expansion frames 3 bent towards each other. After the two expansion frames 3 are extended to both sides, they are inserted perpendicularly to the road shoulder using the positioning component 6, with the bent ends of the expansion frames 3 assisting in insertion into the upper and lower sides of the road shoulder. The position of the protective net 5 is adjusted by the adjusting and limiting component 4, bringing the protective net 5 closer to the slope of the road shoulder to filter rainwater and prevent sand and gravel from rolling down.

[0021] like Figure 3-5 As shown, in order to connect the device to the road shoulder and adjust the angle between the two side extension frames 3 and the road shoulder, the positioning component 6 includes a positioning frame 10 and a stud 11. The positioning frame 10 passes through the connecting plate 1 and is slidably disposed within the connecting plate 1. The stud 11 is rotatably connected to the middle of the upper wall of the connecting plate 1. The stud 11 passes through the positioning frame 10 and extends to the upper part of the positioning frame 10. The stud 11 is threadedly connected to the positioning frame 10. A handle 12 is provided at the through end of the stud 11. The positioning frame 10 is n-shaped. The bottom end is fixedly connected with a rod 13, which is symmetrically distributed in pairs. The positioning frame 10 is perpendicular to the road shoulder surface. The rod 13 is inserted into the road shoulder to fix the position of the connecting plate 1. The handle 12 is rotated in the forward direction to adjust the height of the connecting plate 1, so that it moves upward along the axis of the stud 11. The angle between the two sides of the expansion frame 3 and the road shoulder increases, the angle of the protective net 5 is adjusted, and stones are filled between the bottom of the protective net 5 and the road shoulder surface to increase the stability of the road shoulder surface and prevent sand and gravel from rolling down.

[0022] like Figure 1-3 As shown, in order to adjust and fix the position of the protective net 5 and adjust the coverage position of the vegetation net, the adjusting limiting component 4 includes a sliding sleeve 7 and a limiting screw 8. The sliding sleeve 7 is slidably connected to the parallel outer wall of the expansion frame 3, and the protective net 5 is fixedly connected between the symmetrical outer walls of the sliding sleeve 7. The limiting screw 8 passes through the sliding sleeve 7 and is threaded to the side wall of the sliding sleeve 7 for fixing the position of the sliding sleeve 7. Loosening the limiting screw 8 pushes the sliding sleeve 7 to slide along the length direction of the expansion frame 3 so that one end of the protective net 5 fits against the road shoulder surface. Tightening the locking screw achieves the fixing of the position of the sliding sleeve 7 and the protective net 5.

[0023] A partition 14 is provided on the side wall of the protective netting 5 away from the connecting plate 1. The partitions 14 are arranged at uniform intervals along the length of the expansion frame 3, and planting cavities 9 are formed between adjacent partitions 14. Plants with well-developed root systems are planted on the protective netting 5, allowing the plant roots to extend downwards, pass through the protective netting 5, and insert into the road shoulder and the stone positions above the road shoulder, so that the device is integrated with the road shoulder, improving the soil and water conservation effect.

[0024] In practical use, the operator opens the symmetrical expansion frame 3, inserts the bottom rod 13 of the positioning frame 10 vertically into the road shoulder surface to support the connecting plate 1, and at the same time, bends one end of the expansion frame 3 on both sides and fastens it to the upper and lower surfaces of the road shoulder, or rotates the handle 12 to adjust the height of the connecting plate 1 so that it moves and adjusts along the axis of the stud 11 to adjust the angle of the protective net 5. After adjustment, the bent part of the expansion frame 3 is inserted into the road shoulder.

[0025] When the handle 12 is turned forward, the connecting plate 1 moves upward, the angle between the extended frame 3 on both sides and the shoulder increases, and stones are filled between the bottom of the protective net 5 and the surface of the shoulder to increase the stability of the shoulder surface and prevent sand and gravel from rolling down. At the same time, soil is sprinkled into the planting cavity 9 and planting bags or seeds are prevented from growing in the planting cavity 9, so that the plant roots can extend downward, pass through the protective net 5 and insert into the shoulder and the stone position above the shoulder, so that the device is combined with the shoulder and the soil and water conservation effect is improved.

[0026] When soil, gravel, and other materials on the road shoulder are washed away by rainwater, they are filtered by the protective netting 5 and then blocked by the stones on the road shoulder surface below the protective netting 5, thus improving the soil and water conservation effect.
