[0023] The ladder-shaped slope protection makes the slope surface more stable by forming a certain slope, and the water flow can smoothly flow down along the steps, avoiding direct erosion of the water flow on the slope surface. The upper guide groove 3 and the lower guide groove 4 arranged on the slope surface 2 can further improve the drainage capacity of the slope protection structure.

[0024] The slope body 1 is provided with a drainage groove 5, the drainage groove 5 is fixedly connected to the side edge of the slope body 1, a first fence plate 7 is arranged on the top of the drainage groove 5, an overflow port 9 is arranged at the bottom of the lower guide groove 4, and the drainage groove 5 is communicated with the lower guide groove 4 through the overflow port 9.

[0025] The water discharged from the slope protection structure flows into the drainage groove 5 through the upper guide groove 3 and the lower guide groove 4, and the first fence plate 7 on the top of the drainage groove 5 is used to prevent branches and leaves from falling in.

[0026] The second fence plate 8 is arranged in the lower guide groove 4 and is arranged obliquely, the bracket structure for supporting the lower guide groove 4 is arranged in the lower guide groove 4, the bracket structure is detachably connected with the second fence plate 8, and the second fence plate 8 is arranged above the overflow port 9.

[0027] The second fence plate 8 arranged in the lower flow guide groove 4 is arranged above the overflow port 9, and the inclined design can prevent branches and leaves from entering the drainage groove 5 through the overflow port 9 at the bottom of the lower flow guide groove 4 along with the water flow, while ensuring that the water flow is smooth. The second fence plate 8 is fixed in the lower flow guide groove 4 by a detachable mounting mode, which is convenient for workers to replace the second fence plate 8.

[0028] Regarding the frame structure:

[0029] The frame structure includes at least two groups of fixed frames 10, the fixed frame 10 is U-shaped, and the two ends of the fixed frame 10 are provided with fixed bolts 14 which are threadedly connected with bolt holes arranged in the inner side of the lower flow guide groove 4. The second fence plate 8 is provided with a plurality of fixed buckles cooperating with the fixed frame 10 on one side close to the fixed frame 10.

[0030] The fixed frame 10 is fixed in the inner side of the lower flow guide groove 4 by a bolt connection mode for supporting the second fence plate 8, and the second fence plate 8 is fixed with the two groups of fixed frames 10 by the fixed buckles.

[0031] It is worth noting that the fixed buckle includes two groups of clamping blocks 11, and the two groups of clamping blocks 11 are provided with a gap allowing the fixed frame 10 to be inserted thereinto, and the upper end of the clamping block 11 is fixedly connected with the second fence plate 8. At least two groups of fixed buckles cooperating with the fixed frame 10 are arranged on one group of fixed frames 10, and one group of fixed buckles includes two groups of clamping blocks 11 fixedly arranged on the inner side of the second fence plate 8. When the second fence plate 8 is installed, the fixed frame 10 will be clamped into the insertion slot arranged between the two groups of clamping blocks 11 to limit the second fence plate 8, and the second fence plate 8 will not shake up and down when it is impacted by the water flow.

[0032] In order to avoid the second fence plate 8 shaking left and right on the fixed frame 10 when it is impacted by the water flow, in the preferred scheme, the two groups of clamping blocks 11 are fixedly connected with a strip-shaped rib 12 on the side facing each other, and the strip-shaped rib 12 is slidably connected with a limiting slot 13 arranged on the outer side of the fixed frame 10. After the clamping block 11 is hung on the front and rear sides of the fixed frame 10, the strip-shaped rib 12 on the inner side of the clamping block 11 will also be inserted into the limiting slot 13 arranged on the outer side of the fixed frame 10. The limiting slot 13 limits the clamping block 11 by cooperating with the strip-shaped rib 12 to limit the clamping block 11 from sliding left and right along the outer side wall of the fixed frame 10.

[0033] In order to avoid the first fence plate 7 laid on the top of the drainage groove 5 from sliding off the top of the drainage groove 5 after being washed by rainwater, a cover plate clamping groove 6 is arranged along the upper end of the inner side wall of the drainage groove 5, and the first fence plate 7 is clamped with the cover plate clamping groove 6. The cover plate clamping groove 6 is arranged on the upper end of the inner side wall of the drainage groove 5, and the first fence plate 7 is clamped in the cover plate clamping groove 6 during installation.

After the first fence plate 7 is combined in the cover plate clamping groove 6, the positioning blocks 15 fixed at the lower end of the cover plate clamping groove 6 are also inserted into the insertion slots formed at the bottom of the cover plate clamping groove 6. The insertion slots limit the first fence plate 7 through cooperation with the positioning blocks 15, prevent the first fence plate 7 from moving left and right, and improve the stability of the first fence plate 7 after paving.

[0035] The working principle of the present application is as follows:

[0036] The stepped slope is more stable in surface through forming a certain slope, and water flow can smoothly flow down along the steps to avoid direct erosion of the slope surface by water flow. The slope surface 2 is provided with an upper flow guide groove 3 and a lower flow guide groove 4 to further improve the drainage capacity of the slope structure. The water discharged from the slope flows into the drainage groove 5 through the upper flow guide groove 3 and the lower flow guide groove 4, and the first fence plate 7 at the top of the drainage groove 5 is used to prevent branches and leaves from falling. The second fence plate 8 arranged in the lower flow guide groove 4 is arranged above the overflow port 9, and the inclined design can prevent branches and leaves from entering the drainage groove 5 through the overflow port 9 at the bottom of the lower flow guide groove 4 while ensuring smooth water flow. The second fence plate 8 is fixed in the lower flow guide groove 4 by a detachable mounting manner, which is convenient for workers to replace the second fence plate 8.
