[0018] Example 1

[0019] like Figures 1 to 3 As shown, this utility model proposes a slope protection structure for water conservancy projects to prevent soil erosion, including a slope body 1 and a first slope protection unit; the slope body 1 has a stepped section 101 on its protective surface, a cast-in-place retaining wall 2 at the bottom of the stepped section 101, and a second slope protection unit at the top of the stepped section 101, which is used to protect the slope surface at the top of the slope body 1, facilitate pedestrian walking, and prevent soil erosion; multiple sets of the first slope protection unit are provided, and the multiple sets of the first slope protection unit are evenly distributed on the stepped section 101. The first slope protection unit is used to protect the soil of the slope body 1 step by step, and to divert excess rainwater from the protective surface to prevent rainwater from eroding the soil and causing loss.

[0020] The first slope protection unit includes a slope protection body 3, a first water collection trough 302, a first protective part 305, and a water inlet valve 308. The bottom of the slope protection body 3 is embedded in the stepped part 101, and multiple planting areas 301 are evenly arranged on the slope protection body 3. The first water collection trough 302 is arranged on the slope protection body 3 and is located on one side of the planting area 301. A through hole 303 is opened between two adjacent sets of first water collection troughs 302 for rainwater circulation. The first protective part 305 is installed at the top of the slope protection body 3 and is close to one side of the multiple sets of first water collection troughs 302. The water inlet valve 308 is installed at the top of the slope protection body 3, and the output end of the water inlet valve 308 extends into the first water collection trough 302. A first drain valve 309 corresponding to the first water collection trough 302 is arranged on the slope protection body 3. A connecting pipe 4 connects the first drain valve 309 and the water inlet valve 308 between two adjacent sets of slope protection bodies 3.

[0021] Furthermore, the bottom end of the first water collection tank 302 is provided with an inclined part 304, which facilitates the water collected in the first water collection tank 302, on which the first drain valve 309 is installed, to flow outward along the first drain valve 309.

[0022] Furthermore, the first slope protection unit also includes a second protection section 306 and a first grid plate 307; multiple sets of second protection sections 306 are provided, and multiple sets of second protection sections 306 are evenly distributed on the top of the slope protection body 3. The second protection sections 306 are located between two adjacent planting areas 301, and the second protection sections 306 are connected to the first protection section 305; multiple sets of first grid plates 307 are provided, and the first grid plates 307 correspond to the first water collection trough 302. The bottom end of the first grid plate 307 is hinged to the top of the slope protection body 3, and the other end of the first grid plate 307 is detachably connected to the first protection section 305 by bolts. The first grid plate 307 is inclinedly arranged on the slope protection body 3.

[0023] Furthermore, the slope protection body 3, the first protective section 305, and the second protective section 306 are all constructed of bricks and cement, which enhances the protection of the slope 1, improves the stability of the protection, and extends the service life.

[0024] In this embodiment, multiple sets of slope protection bodies 3 are sequentially embedded inside the stepped section 101, and the cast-in-place retaining wall 2 is connected to the bottom of the stepped section 101 and the lowest set of slope protection bodies 3 to protect the bottom of the slope 1. A connecting pipe 4 connects the water inlet valve 308 on two adjacent sets of slope protection bodies 3 to the first drainage valve 309. Vegetation is planted in the soil inside the planting area 301, and the roots of the vegetation grip the soil to prevent soil erosion. The slope protection bodies 3 provide protection and support for the soil on the slope 1, preventing soil loss and improving stability. The second protective part 306 facilitates the blocking of water and soil between two adjacent planting areas 301 within the slope protection body 3, and the first protective part 305 facilitates the interception of water and soil within the slope protection body 3. The system intercepts and filters rainwater-washed soil and impurities such as leaves, preventing them from being washed into the first water collection trough 302 and clogging the first drainage valve 309. The top of the first grid plate 307 and the first protective part 305 are detachable, facilitating regular cleaning of the first water collection trough 302 and the first grid plate 307. Rainwater from the upper set of slope protection bodies 3 flows into the first water collection trough 302 and is then discharged through the first drainage valve 309 and connecting pipe 4 into the inlet valve 308 of the lower set of slope protection bodies 3, eventually entering the first water collection trough 302 in the lower set of slope protection bodies 3. This process is repeated until the rainwater is discharged downwards step by step, preventing rainwater from washing away the planting area 301 and causing soil erosion.

The top casting base 5 is L-shaped, and its top end is connected to the top end of the slope 1. The side wall of the top casting base 5 is connected to the stepped part 101 and the uppermost set of slope protection bodies 3. A second water collection trough 501 is provided on the top casting base 5, and the second water collection trough 501 is embedded inside the slope 1. A second drain valve 502 is provided at the connection between the bottom of the side wall of the water tank 501 and the top casting base 5, which is used to connect to the water inlet valve 308 in the second slope protection unit through the connecting pipe 4; the third protective part 503 is C-shaped and is installed at the top of the top casting base 5 and close to the second water collection tank 501; the second grating plate 504 corresponds to the second water collection tank 501, one end of the second grating plate 504 is hinged to the top casting base 5, and the other end is detachably connected to the third protective part 503 by bolts.

[0027] Furthermore, both the second water-gathering trough 501 and the third protective section 503 are constructed of bricks and cement, enhancing the protection of the slope 1, improving its stability, and extending its service life.

[0028] In this embodiment, a top casting base 5 is poured with concrete at the top of the slope 1, and a second water collection trough 501 is built on the top casting base 5. The third protective part 503 facilitates the guidance of rainwater from the top casting base 5 into the second water collection trough 501. The second grid plate 504 facilitates the interception and filtration of impurities in the rainwater, preventing them from entering the second water collection trough 501 and causing blockage of the second drainage valve 502. The second drainage valve 502 is connected to the water inlet valve 308 in the adjacent first slope protection unit through the connecting pipe 4, thereby guiding the rainwater at the top of the top casting base 5 into the first water collection trough 302, preventing it from directly eroding the first slope protection unit along the top casting base 5 and causing soil erosion.
