Description

Technical Field

[0001] This utility model belongs to the field of slope protection and stabilization technology, specifically relating to a slope protection and stabilization structure for geotechnical engineering. Background Technology

[0002] Geotechnical engineering mainly studies the properties of rock and soil as engineering foundations, engineering environments, and engineering materials, as well as their utilization, remediation, or modification in engineering construction. Rock mass slope protection aims to ensure the stability of the rock mass, reduce slope instability, protect personnel and property, maintain the stability of engineering structures, and protect the environment and ecosystem. Since most rock mass slopes are rugged, the commonly used protection measure is the use of protective nets. However, protective nets have certain limitations. When it rains, they cannot block rainwater. The erosion and infiltration of rainwater can reduce the shear strength of the rock and soil, cause soil erosion on the slope, and raise the groundwater level, leading to slope instability. Therefore, a protection structure that can be used on rugged slopes and has the effect of intercepting rainwater is needed. Utility Model Content

[0003] This utility model provides a slope protection structure for geotechnical engineering. It features a protective net with interception effect that can be formed by several hexagonal connecting frames, thereby improving the stability and safety of the slope. Since the hexagonal connecting frames are connected by several connecting rings, when a local part of the protective net is damaged, it can be repaired by replacing the hexagonal connecting frames, thus reducing losses.

[0004] This utility model provides the following technical solution: it includes several hexagonal connecting frames, each with a rain shield on its inner side. The hexagonal connecting frames are connected by several connecting rings. Each connecting ring includes an arc-shaped rod one and an arc-shaped rod two. One end of the arc-shaped rod one and one end of the arc-shaped rod two are rotatably connected, and the other end of the arc-shaped rod one is movably connected to the other end of the arc-shaped rod two. The three sides on the right side of each hexagonal connecting frame are provided with arc-shaped plates, which are movably connected to the left side of the adjacent hexagonal connecting frame. The connecting rings are located inside the arc-shaped plates.

[0005] The hexagonal connecting frame has several connecting holes on its three right sides, and the connecting ring is movably connected to the connecting holes.

[0006] The hexagonal connecting frame has several connecting holes 2 on each of its three left sides, and the connecting ring is movably connected to the connecting holes 2.

[0007] The inner arc surface of the arc plate is provided with several fixing blocks, and the fixing blocks are provided with through grooves that match the size of the connecting ring.

[0008] The hexagonal connecting frame has connecting grooves on three sides on its left side, and the arc-shaped plate is movably connected to the connecting grooves.

[0009] One end of the arc-shaped rod is provided with a connecting groove, and one end of the arc-shaped rod is provided with a connecting block, which is located inside the connecting groove.

[0010] The arc-shaped plate is sized to match the connecting ring, and the second connecting hole is symmetrical to the first connecting hole.

[0011] The beneficial effects of this utility model are as follows: a protective net with interception effect can be formed by several hexagonal connecting frames, which avoids the reduction of shear strength of rock and soil, soil erosion on slope surface and instability caused by the erosion and infiltration of a large amount of rainwater, thus improving the stability and safety of the slope. Since several hexagonal connecting frames are connected by several connecting rings, when a part of the protective net is damaged, it can be repaired by replacing the hexagonal connecting frames, without having to replace the entire protective net, thus reducing losses.

[0018] Please see Figures 1-4The present invention provides the following technical solution: it includes several hexagonal connecting frames 1, with a rain shield 11 on the inner side of the hexagonal connecting frame 1. The several hexagonal connecting frames 1 are connected by several connecting rings 2. The connecting ring 2 includes an arc-shaped rod 1 21 and an arc-shaped rod 22. One end of the arc-shaped rod 1 21 and one end of the arc-shaped rod 22 are rotatably connected, and the other end of the arc-shaped rod 1 21 is movably connected to the other end of the arc-shaped rod 22. The three sides on the right side of the hexagonal connecting frame 1 are provided with arc-shaped plates 14. The arc-shaped plates 14 are movably connected to the left side of the adjacent hexagonal connecting frame 1. The connecting ring 2 is located inside the arc-shaped plates 14.

[0019] This implementation plan includes several hexagonal connecting frames 1, each with a fixed shape. The inner side of each hexagonal connecting frame 1 is equipped with a rain shield 11, which intercepts rainwater, preventing the erosion and infiltration of large amounts of rainwater that could reduce the shear strength of the soil and rock, cause soil erosion, and lead to slope instability due to rising groundwater levels. This improves the stability and safety of the slope. The hexagonal connecting frames 1 are connected by several connecting rings 2. Adjacent sides of two adjacent hexagonal connecting frames 1 are connected by these connecting rings 2, forming a protective net with a flow-intercepting effect. Each connecting ring 2 includes an arc-shaped rod 21 and an arc-shaped rod 22. The second arc-shaped rod 22 has the same dimensions. When both ends of the first arc-shaped rod 21 and the second arc-shaped rod 22 are aligned, the connecting ring 2 will be in a circular state. When the connecting ring 2 is connected to the two hexagonal connecting frames 1, the angle between the two connecting rings 2 is adjustable, thus ensuring the flexibility of the protective net. One end of the first arc-shaped rod 21 and one end of the second arc-shaped rod 22 are rotatably connected, and the other end of the first arc-shaped rod 21 is movably connected to the other end of the second arc-shaped rod 22. By rotating the first arc-shaped rod 21 and the second arc-shaped rod 22, the distance between the other ends of the first arc-shaped rod 21 and the second arc-shaped rod 22 can be adjusted. When the distance between the ends of the first arc-shaped rod 21 and the second arc-shaped rod 22 increases, the connecting ring 2 can be connected to the hexagonal connecting frame 1, and then the first arc-shaped rod 21 and the second arc-shaped rod 22 can be connected. 22. Rotating to the aligned position allows the two hexagonal connecting frames 1 and connecting ring 2 to be movably connected. The three right sides of the hexagonal connecting frame 1 are provided with arc-shaped plates 14, which are fixedly connected to the hexagonal connecting frame 1 and movably connected to the left side of the adjacent hexagonal connecting frame 1. When two adjacent hexagonal connecting frames 1 are connected via connecting ring 2, the arc-shaped plate 14 of the left hexagonal connecting frame 1 connects to the right hexagonal connecting frame 1, thus positioning the arc-shaped plate 14 between the two adjacent hexagonal connecting frames 1. The arc shape of the arc-shaped plate 14 can block the gap between the two hexagonal connecting frames 1, preventing rainwater from seeping into the rock mass through the gap between the two hexagonal connecting frames 1, reducing the amount of rainwater infiltration, and minimizing the impact of rainwater on the rock mass. The connecting ring 2 is located inside the arc-shaped plate 14. When the connecting ring 2 is connected to the two hexagonal connecting frames 1, the connecting ring 2 will be located on one side of the inner arc surface of the arc-shaped plate 14. The arc-shaped plate 14 can shield the connecting ring 2 from the rock mass, preventing the connecting ring 2 from deforming and separating from the hexagonal connecting frame 1 due to contact with the rock mass. Several hexagonal connecting frames 1 can form a protective net with interception effect, preventing the erosion and infiltration of large amounts of rainwater from reducing the shear strength of the soil and rock mass, causing slope instability due to soil erosion and groundwater level rise, thus improving the stability and safety of the slope. Since several hexagonal connecting frames 1 are connected by several connecting rings 2, when a local part of the protective net is damaged,The problem can be repaired by replacing the hexagonal connecting frame 1; there is no need to replace the entire protective netting, thus reducing wear and tear.

[0020] The three sides of the right side of the hexagonal connecting frame 1 are provided with several connecting holes 12. The connecting ring 2 is movably connected to the connecting holes 12. The size of the connecting holes 12 matches that of the connecting ring 2, and the connecting holes 12 are arc-shaped, so the connecting ring 2 can slide into the connecting holes 12.

[0021] The three sides on the left side of the hexagonal connecting frame 1 are provided with several connecting holes 2 13. The connecting ring 2 is movably connected to the connecting holes 2 13. The size of the connecting holes 2 13 matches that of the connecting ring 2, and the connecting holes 2 13 are also arc-shaped. The arc of the connecting holes 2 13 is the same as that of the connecting holes 1 12, so the connecting ring 2 can slide into the connecting holes 2 13.

[0022] The inner arc surface of the arc plate 14 is provided with several fixing blocks 141, and the fixing blocks 141 are provided with through grooves 142, which are matched with the size of the connecting ring 2. The fixing blocks 141 are fixedly connected to the arc plate 14, and the positions of the several fixing blocks 141 and the several connecting holes 12 correspond to each other. When the distance between the ends of the arc rod 21 and the arc rod 22 is large, one end of the arc rod 21 or the arc rod 22 can be slid into the connecting hole 12, the through groove 142 and the connecting hole 23. Then, the arc rod 21 and the arc rod 22 can be rotated to the ring state, so that the connecting ring 2 can be connected to the two hexagonal connecting frames 1. After the connecting ring 2 is connected to the two hexagonal connecting frames 1, by rotating the movable end of the arc rod 21 and the arc rod 22 to the inside of the through groove 142, the misalignment and detachment caused by the rotation between the arc rod 21 and the arc rod 22 can be avoided.

[0023] Connecting grooves 15 are provided on three sides of the left side of the hexagonal connecting frame 1, and the arc plate 14 is movably connected to the connecting grooves 15. The dimensions of the connecting grooves 15 and the arc plate 14 are matched. When two adjacent hexagonal connecting frames 1 are connected, the arc plate 14 on the left hexagonal connecting frame 1 needs to slide into the inner side of the connecting groove 15 on the right hexagonal connecting frame 1.

[0024] One end of the arc-shaped rod 21 has a connecting groove 211, and one end of the arc-shaped rod 22 has a connecting block 221, which is located inside the connecting groove 211. The shapes of the connecting groove 211 and the connecting block 221 are matched. Through the connection between the connecting block 221 and the connecting groove 211, one end of the arc-shaped rod 22 and the arc-shaped rod 21 is rotatable.

[0025] The dimensions of the arc plate 14 and the connecting ring 2 are matched, and the connecting hole 2 13 and the connecting hole 12 are symmetrical to each other. When the connecting ring 2 is connected to the hexagonal connecting frame 1, the center of the connecting ring 2 corresponds to the center of the arc plate 14. Therefore, there is always a distance between the connecting ring 2 and the arc plate 14.

[0026] The working principle and usage process of this utility model are as follows: In use, firstly, the arc-shaped rod 21 and the arc-shaped rod 22 are rotated. When the distance between the ends of the arc-shaped rod 21 and the arc-shaped rod 22 increases, one end of the arc-shaped rod 21 or the arc-shaped rod 22 can be slid into the connecting hole 12, the through groove 142 and the connecting hole 13. Then, the arc-shaped rod 21 and the arc-shaped rod 22 are rotated to a circular state, so that the connecting ring 2 can be connected to the two hexagonal connecting frames 1. After the connecting ring 2 is connected to the two hexagonal connecting frames 1, by rotating the movable end of the arc-shaped rod 21 and the arc-shaped rod 22 to the inside of the through groove 142, the misalignment and detachment caused by the rotation between the arc-shaped rod 21 and the arc-shaped rod 22 can be avoided. The hexagonal connecting frame 1, the rain shield 11 and the arc plate 14 can intercept rainwater.
