[0032] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] The following Figures 1 to 4 , describe the embodiments of the present utility model.

[0034] As Figure 1 shown, according to an embodiment of the utility model, a slope protection device is provided. The slope protection device includes a first protection part 100; a second protection part 200, which is rotatably connected to the first protection part 100; and a fixing member 4, which is a rigid column body, and one end thereof is provided with a pointed end so that the first protection part 100 and the second protection part 200 are fixed to the slope 5. Among them, the first protection part 100 and the second protection part 200 are respectively provided with a plurality of drainage grooves 6, so that the whole slope protection device can form a net shape.

[0035] In this embodiment, in combination with Figure 1 and Figure 3As shown in the figure, the slope protection device includes a first protection part 100, a second protection part 200 and a fixing member 4. The first protection part 100 and the second protection part 200 can be respectively sheet-like structures or layered structures with a certain thickness, which is conducive to laying on the slope 5. One end of the first protection part 100 is rotatably connected to one end of the second protection part 200, so that when the slope protection device is laid on the slope 5, it can be adjusted according to the shape of the slope 5, improving the adaptability of the slope protection device to the undulation of the slope 5. When the slope 5 is set at a certain angle, the first protection part 100 and the second protection part 200 can be adjusted to adapt to the angle of the slope 5 by rotating relative to each other, which also improves the laying efficiency of the slope protection device. For example, if the top of the slope 5 is a flat horizontal slope surface and the lower part of the slope 5 is a slope extending along the horizontal slope surface, the first protection part 100 can be laid on the relatively flat slope surface, the first protection part 100 is arranged at the slope top, and the second protection part 200 is arranged on the slope along the drainage direction.

[0036] The fixing member 4 is a hard columnar structure, and a pointed end is provided at one end of the fixing member 4, which is convenient for construction workers to quickly fix the fixing member 4 in the slope 5, greatly improving the installation efficiency. Of course, the fixing member 4 can also adopt anchor bolts and steel bars with the same diameter.

[0037] The first protection part 100 and the second protection part 200 respectively include a plurality of drainage grooves 6, so as to have sufficient passages for drainage and prevent excessive water accumulation during the rainy season, thus avoiding landslide problems. Among them, the drainage grooves 6 are arranged to drain water from top to bottom in the use state.

[0038] The above-mentioned slope protection device can be used temporarily during the rainy season to form a soil slope stabilizing member. The external dimensions of the slope protection device in length × width × height are 50 cm × 40 cm × 5 cm, and the net dimensions of the drainage grooves 6 on both sides in width × depth are 10 cm × 5 cm, which is convenient for handling.

[0039] Optionally, the first protection part 100 and the second protection part 200 respectively include a plurality of drainage units 300, and the plurality of drainage units 300 are spliced into a net structure, and each drainage unit 300 is provided with at least one drainage groove 6.

[0040] The plurality of drainage units 300 are spliced with each other to form a net structure, which is convenient for maintaining the slope protection device. For example, if a certain drainage unit 300 is damaged, only the damaged drainage unit 300 needs to be replaced, so that the entire slope protection device can be reused, improving the utilization rate, saving costs, and further improving the protection effect because only the locally damaged drainage unit 300 needs to be replaced in time.

[0041] Optionally, in the drainage direction, the plurality of drainage units 300 are connected into strips, and adjacent two drainage units 300 are rotatably connected.

[0042] In this embodiment, two adjacent drainage units 300 in the drainage direction are rotatably connected, so that each drainage unit 300 can rotate by a certain angle, thereby adapting to slopes 5 with different flatness levels within a smaller range, and further improving the adaptability of the slope protection device to the slope 5. A plurality of drainage units 300 are sequentially connected in a strip shape in the drainage direction, that is, a plurality of drainage grooves 6 are sequentially connected in a strip shape to form an integral drainage ditch, improving the drainage efficiency and further reducing the scouring and infiltration of rainwater on the soil slope. In addition, the arranged strip-shaped drainage units 300 facilitate guiding the accumulated water flow direction and improve the drainage efficiency.

[0043] Optionally, as Figure 2 and Figure 3 shown, the drainage unit 300 includes: two fixing blocks 1, each fixing block 1 is provided with a drainage groove 6; a stiffening rib 2 connecting the two fixing blocks 1; wherein, in the drainage direction, the two fixing blocks 1 corresponding to two adjacent drainage units 300 are rotatably connected.

[0044] In this embodiment, in combination with Figure 2 shown, the drainage unit 300 includes a fixing block 1 and a stiffening rib 2. Among them, at least one stiffening rib 2 is arranged between the two fixing blocks 1. One end of the stiffening rib 2 can extend to the bottom of one of the fixing blocks 1, and the other end of the stiffening rib 2 can extend to the bottom of the other fixing block 1, so that the fixing member 4 can pass through the fixing block 1 and the stiffening rib 2, enhancing the self-structural strength of the fixing block 1 on the premise of saving materials. One end of the fixing block 1 is provided with a pin 3 hole, and the other end is provided with a sleeve 8. In the drainage direction, two adjacent fixing blocks 1 are rotatably connected through a pin 3 inserted into the pin 3 hole and the sleeve 8, forming an effective constraint while being convenient for disassembly to facilitate reuse.

[0045] Among them, the stiffening rib 2 is arranged obliquely in the drainage direction, which not only enhances the self-structural strength of the fixing block 1, but also improves the flow pattern and velocity of rainwater between the drainage grooves 6, reducing the scouring of rainwater on the soil slope.

[0046] Each drainage unit 300 can be provided with three inclined stiffening ribs 2, and the three stiffening ribs 2 are sequentially and spaced from each other in the drainage direction and connected between the two fixing blocks 1 to form a structure in the shape of a Chinese character 'ri'.

[0047] Continuing to combine with Figure 1As shown, in the drainage direction, the ends of adjacent two fixing blocks 1 that are rotatably connected to each other are arranged to be overlappable, so that a plurality of drainage grooves 6 in the drainage direction form a continuous water channel. Specifically, one end of the fixing block 1 is an insertion end. For example, the end of the fixing block 1 where the sleeve 8 is provided is the insertion end. The width of the insertion end is smaller than the net width of the drainage groove 6, and the bottom end of the insertion end is rounded, so that the adjacent two fixing blocks 1 can have a rotation range within ±10, improving the adaptability to the undulation of the soil slope and reducing the requirement for the flatness of the soil slope surface. Among them, the outer dimension of the insertion end is 1 mm to 2 mm smaller than the net width of the drainage groove 6, the bottom is retracted by 6 mm, and the bottom end is rounded to facilitate rotation at a certain angle.

[0048] In this embodiment, the height of the fixing block 1 can be 5 cm to 6 cm, the thickness of the stiffening rib 2 can be 4 mm to 5 mm, and the width can be 3 cm to 4 cm. The fixing member 4 is an anchor nail with a diameter of 12 mm to 16 mm and a length of 50 cm to 100 cm. The bolt 3 can be a connecting bolt with a diameter of 16 mm to 18 mm, and the inner diameter of the sleeve can be 20 mm.

[0049] Optionally, the fixing member 4 is fixed at the central position of the drainage groove 6, avoiding the problem of rainwater flowing out due to the offset of the drainage groove 6 caused by rainwater impact, and ensuring the smooth progress of the drainage process.

[0050] In addition, the fixing block 1 is made of plastic material, with a small self-weight and low cost, and is more convenient for transportation and storage than other protective components.

[0051] Optionally, it further includes a geogrid 7, which is arranged on the surfaces of the first protection part 100 and the second protection part 200 that are in contact with the slope 5 respectively.

[0052] In this embodiment, continuing to combine Figure 1 As shown, after the slope 5 is quickly leveled, a layer of geogrid 7 is laid. After laying the overall drainage net composed of the first protection part 100 and the second protection part 200 from the top to the bottom of the soil slope, the fixing member 4 is driven in to fixedly connect the geogrid 7, the fixing block 1 and the slope 5, and thus complete the overall protection of the slope 5.

[0053] The slope protection device provided by this application is a temporarily reusable soil slope stabilizing component during the rainy season. The component is anchored on the soil slope, which can be disassembled and assembled repeatedly, quickly form a stable system on the soil slope surface, can use the drainage groove 6 to accelerate the organized drainage of rainwater, and can also use the inclined stiffening rib 2 to reduce the scouring of rainwater on the soil slope surface.

[0054] In summary, the slope protection device can be reused for temporary soil slopes. It has relatively low requirements for the flatness of the soil slope, is easy to assemble and can be disassembled and reused. It can not only form an effective constraint on the surface of the temporary soil slope, but also use the grooves on the fixing block 1 to quickly and orderly drain rainwater, effectively enhancing the integrity of the temporary soil slope, reducing the scouring and infiltration of rainwater on the soil slope, and avoiding the instability, landslide or collapse of the temporary soil slope.
