Guide rods are fixedly connected to the interiors of the plurality of guide grooves. A guide block is slidably connected to the outer side wall of the guide rod. The rear surface of the guide block is fixedly connected to the front surface of the installation box; A T-shaped groove is formed at the bottom of the mounting plate, and a T-shaped block is fixedly connected to the top of the sealing baffle inside the T-shaped groove.

[0006] Furthermore, a first filter screen plate is snap-fitted inside the sedimentation tank.

[0007] Furthermore, an overflow pipe is provided on the left side of the slope platform, and the upper part inside the sedimentation tank on the upper left side of the slope platform is fixedly communicated with the right end of the overflow pipe.

[0008] Furthermore, the pumping mechanism includes a drain pipe, the left end of the drain pipe is fixedly communicated with the lower part inside the sedimentation tank on the upper right side of the slope platform, the rear end of the drain pipe is fixedly connected to a filter box, the rear surface of the filter box is fixedly communicated with a suction pipe, the end of the suction pipe away from the filter box is fixedly communicated with a variable-frequency pump, and the bottom of the variable-frequency pump is fixedly connected to the upper surface of the slope.

[0014] Beneficial effects: The intermittent variable-angle design of the drainage channel slows down the water flow speed. The 30-degree slope section can quickly divert surface runoff to avoid frost heaving caused by waterlogging penetration. The 5-degree gentle slope section promotes the natural sedimentation of sediment by reducing the water flow speed, reduces soil erosion, and disperses hydraulic scouring. The alternating slopes break the continuity of the water flow, reduce the erosion risk of the slope surface caused by concentrated scouring, and at the same time reduce the damage to the structure caused by ice accumulation. It adapts to freeze-thaw cycles. The variable-angle design can relieve the deformation of the channel body caused by ice expansion during the freeze-thaw process and enhance the structural durability. In dry weather conditions, the accumulated water stored inside the sedimentation tank can be pumped out by a variable-frequency pump, and then discharged through multiple shunt hoses. The vegetation on the slope can be irrigated through the irrigation mechanism, and the water purified from the runoff intercepted by the sedimentation tank can be reused for slope irrigation, alleviating the water shortage problem in high-altitude areas and promoting the development of vegetation roots. Combining the water control systems of the drainage channel and the sedimentation tank forms a virtuous cycle of "soil fixation - water conservation - erosion reduction". During the repeated left-right movement of the sealing baffle, the top of the L-shaped anti-disconnection hook will be intermittently squeezed by multiple trapezoidal blocks, driving the sealing baffle to descend. With the cooperation of Spring 1, while achieving repeated left-right movement, it will move up and down reciprocally, causing the spray pipe to approach or move away from the slope surface. Combining with the intermittent variable-frequency pumping of the variable-frequency pump to increase or decrease the water outlet pressure, when the spray pipe approaches the slope surface, the water outlet pressure decreases to avoid water impact on the soil. When the spray pipe moves away from the slope surface, the water delivery pressure increases, and combined with the rotation of the spray pipe, the spraying range is increased to make the irrigation more comprehensive.

Taking advantage of the characteristics of the roots of Picea crassifolia, which are developed and shallow-rooted, they are arranged in a plum blossom shape, and shrubs and herbs are evenly distributed among the Picea crassifolia, so that the soil is fixed by the coupled network formed by the arbor-shrub-herb vegetation, reducing soil erosion. During the vegetation restoration process of slope platform 1 and slope surface 2, non-woven fabrics and straw curtains can be used for covering. After the grass seeds of the herbaceous vegetation grow stably, the non-woven fabrics and straw curtains are removed. After covering the soil, herbaceous plants and shrubs are planted first. After the herbaceous plants grow stably, arbors are planted. There must be more than three kinds of herbaceous plants, and one of them must be a constructive species. The ecological restoration measures of combining arbors, shrubs and herbs are used to reinforce the slope stability.

[0019] A pumping mechanism 5 is arranged on the right side of slope platform 1; The pumping mechanism 5 includes a drain pipe 501. The left end of the drain pipe 501 is fixedly communicated with the lower part inside a sedimentation tank 4 located on the upper right of the upper surface of slope platform 1. The rear end of the drain pipe 501 is fixedly connected with a filter box 502. The rear surface of the filter box 502 is fixedly communicated with a suction pipe 503. One end of the suction pipe 503 far from the filter box 502 is fixedly communicated with a variable frequency pump 504. The bottom of the variable frequency pump 504 is fixedly connected with the upper surface of slope surface 2; The output end of the variable frequency pump 504 is fixedly communicated with a plurality of shunt hoses 505 inside an installation box 601.

The vegetation on the slope surface is irrigated through the irrigation mechanism 6. The water purified from the runoff intercepted by the sedimentation tank 4 is reused for the irrigation of slope surface 2, alleviating the problem of water resource shortage in high-altitude areas, promoting the root development of vegetation, and combining with the water control system of the drainage ditch 3 and the sedimentation tank 4 to form a virtuous cycle of "soil fixation - water conservation - erosion reduction". The second filter screen 506 is convenient for disassembly and replacement to avoid affecting the pumping problem after being blocked.

[0020] An irrigation mechanism 6 is arranged on the upper surface of slope surface 2; The irrigation mechanism 6 includes an installation box 601. A sealing baffle 602 is provided on the front surface of the installation box 601. A plurality of pipe heads 603 are embedded and installed on the front surface of the sealing baffle 602. The front ends of the pipe heads 603 are rotationally communicated with a plurality of spray pipes 604 through rotating shafts. A gear 605 is fixedly connected to the outer side wall of the spray pipe 604. A rack 606 is commonly engaged with the outer side walls of the plurality of gears 605; A plurality of movable openings 607 are formed on the front surface of the installation box 601 behind the sealing baffle 602. An L-shaped anti-disengagement hook 608 is slidably connected to the inner side of the plurality of movable openings 607 on the rear surface of the sealing baffle 602. A plurality of trapezoidal stoppers 609 are fixedly connected to the inner front surface of the installation box 601 above the plurality of L-shaped anti-disengagement hooks 608; A plurality of connecting rods 616 are fixedly connected to the rear surface of the rack 606. A mounting plate 617 is commonly fixedly connected to the rear ends of the plurality of connecting rods 616. A plurality of guide grooves 618 are formed on the rear surface of the mounting plate 617. Guide rods 619 are fixedly connected to the interiors of the plurality of guide grooves 618. A guide block 620 is slidably connected to the outer side wall of the guide rod 619. The rear surface of the guide block 620 is fixedly connected to the front surface of the installation box 601; A T-shaped groove 621 is formed at the bottom of the mounting plate 617. A T-shaped block 622 is fixedly connected to the inside of the T-shaped groove 621 at the top of the sealing baffle 602.

[0021] A vertical groove 610 is formed on the rear surface of the sealing baffle 602 and to the left of the installation box 601. A vertical rod 611 is fixedly connected to the inside of the vertical groove 610. A lifting block 612 is slidably connected to the outer side wall of the vertical rod 611. A first spring 613 is commonly fixedly connected to the upper surface of the lifting block 612 and the inner upper surface of the vertical groove 610 and to the outside of the vertical rod 611. A pressure receiving plate 614 is fixedly connected to the rear surface of the lifting block 612 and to the left of the installation box 601. A plurality of second springs 615 are fixedly connected between the right side of the pressure receiving plate 614 and the left side of the installation box 601; A motor 8 is fixedly connected to the upper left side of the upper surface of the slope 2. The top end of the output shaft of the motor 8 is fixedly connected to a cam 9. The outer side wall of the cam 9 is in contact with the left side of the pressure receiving plate 614; The water pumped by the variable frequency pump 504 will be split into a plurality of pipe heads 603 through the split flow hose 505, and then sprayed and irrigated through the plurality of spray pipes 604; The sealing baffle 602 is installed on the front surface of the installation box 601 through the plurality of L-shaped anti-disengagement hooks 608 provided, so as to realize the sealing and shielding of the movable openings 607. At the same time, the sealing baffle 602 can move left and right or up and down; During the up-and-down movement of the sealing baffle 602, the connection between the T-shaped block 622 and the T-shaped groove 621 will drive the mounting plate 617 to move up and down together, causing the guide rod 619 to slide along the inner side of the guide block 620. Thus, when the gear 605 moves up and down, the rack 606 will move up and down together. At the same time, the T-shaped block 622 can slide inside the T-shaped groove 621, and the mounting plate 617 is limited in the vertical direction by the guide rod 619 and the guide block 620. When the sealing baffle 602 is repeatedly moved left and right under the extrusion of the cam 9, the T-shaped block 622 will slide along the inner side of the T-shaped groove 621, thus not affecting the left-and-right movement of the sealing baffle 602; The motor 8 drives the cam 9 to rotate, periodically pressing the pressure receiving plate 614, and controls the movement of multiple pipe heads 603 and the spray pipe 604 to move left and right repeatedly by pushing the sealing baffle 602, increasing the irrigation coverage range. And with the meshing transmission of the gear 605 and the rack 606, when the spray pipe 604 moves left and right reciprocally, the gear 605 will move left and right reciprocally along the rack 606, thus rotating reciprocally, driving the spray pipe 604 to rotate reciprocally for rotary spraying, further expanding the spraying effect; During the left-and-right repeated movement of the sealing baffle 602, the top of the L-shaped anti-disengagement hook 608 will be intermittently pressed by multiple trapezoidal stoppers 609, driving the sealing baffle 602 to descend. And with the cooperation of the first spring 613, while realizing the left-and-right repeated movement, it will move up and down reciprocally, causing the spray pipe 604 to approach or move away from the slope 2. At the same time, with the meshing transmission of the gear 605 and the rack 606, the spray pipe 604 rotates and sprays reciprocally. With the intermittent variable-frequency pumping of the variable-frequency pump 504, the water outlet pressure is increased or decreased. When the spray pipe 604 approaches the slope 2, the water outlet pressure is reduced to avoid water impacting the soil. When the spray pipe 604 moves away from the slope 2, the water delivery pressure is increased, and with the rotation of the spray pipe 604, the spraying range is increased, making the irrigation more comprehensive; In actual application, one end of the telescopic support rod body of multiple spray pipes 604 is inserted into the adjacent soil, and the other end is rotatably connected to the outer wall of the spray pipe 604 for support, making the use of multiple spray pipes 604 more stable.
