[0002] Ecological restoration is a comprehensive method of repairing polluted environment under the guidance of ecological principles, based on biological restoration, combining various physical restoration, chemical restoration and engineering technical measures to achieve the best effect and lowest cost through optimized combination. When restoring the ecology of mountains with severe mudslides, it is necessary to plant trees for restoration, and it is also necessary to set up drainage ditches for timely drainage to alleviate mudslides.

[0003] The existing drainage ditches used for mountain ecological restoration still have the following shortcomings:

[0004] The discharge method cannot be adjusted according to the amount of rainfall, and emergency discharge cannot be achieved when the discharge channel is blocked, and the structural quality is poor; although a tilted filtering structure is provided, when the filtering structure is cleaned, debris at the filtering structure is easy to fall into the drainage ditch, affecting the cleaning efficiency, and the filtering structure cannot support the road plate, resulting in a weakened stress strength of the road plate and easy fracture under stress.

[0005] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a double-layer structure drainage ditch for ecological restoration is provided, in order to achieve a more practical purpose. Summary of the invention

After polishing, the lower end of the plug-in rods is an arc-shaped structure. The two plug-in rods on the bottom end surface of each filter plate are plugged into the support block.

[0010] Furthermore, a holding block is welded on each filter plate, and the holding block is a rectangular block structure.

[0011] Furthermore, a reinforcement block is cast in the drainage trough. The reinforcement block is a concave structure and is made of iron. The support block is welded to the reinforcement block.

[0012] Furthermore, two first auxiliary blocks are cast on the outer side of the drainage trough, and the two first auxiliary blocks are pre-buried in the soil.

[0013] Furthermore, a second auxiliary block is fixed on the inner wall of the drainage trough. The second auxiliary block is made of metal and has a concave block structure. The bottom end face, left end face and right end face of the second auxiliary block are respectively in contact with the bottom end face, left end face and right end face of the inner wall of the drainage trough.

[0014] Furthermore, an auxiliary component is installed inside the drainage trough, and the auxiliary component consists of a mounting frame, a guide plate, a first electric cylinder and a closing plate.

[0021] Convenient installation and maintenance: The filter plate is fixed by plugging the plug rod and the support block, which is easy and stable to install; the design of the holding block makes it easier to disassemble and replace the filter plate, improving maintenance efficiency.

[0022] Enhanced structural strength: The reinforced blocks cast in the gutter and the pre-buried first auxiliary blocks significantly improve the overall strength and stability of the gutter, preventing damage or displacement caused by external force or water flow impact.

[0023] Eco-friendly design: The setting of drainage pipes and valves allows the drainage trough to be used as an irrigation water source when needed, providing moisture for surrounding trees and promoting the restoration and protection of the ecological environment.

[0024] Humanized design: The transport slot design on the track board makes it easier for workers to operate when transporting and installing the track board, thus improving work efficiency and safety.

[0025] Design to reduce damage: Through the setting of the second auxiliary block, when water flows into the drain trough, it will come into contact with the second auxiliary block. Since the second auxiliary block is made of metal, it avoids the impact of water on the drain trough, which causes damage to the bottom of the drain trough due to long-term impact of water, thereby reducing subsequent maintenance costs.

During use, grass clippings, stones and mud can be initially filtered through the first filter hole 201, thereby preventing grass clippings, stones and mud from entering the drainage trough 1 and affecting drainage; a filter assembly 3 is installed in the drainage trough 1, and the filter assembly 3 is composed of a support block 301, a filter plate 302, a second filter hole 303, a third filter hole 304, a gripping block 305 and a plug-in rod 306. Two support blocks 301 are symmetrically fixed inside the drainage trough 1, and filter plates 302 are placed in a linear array on the two support blocks 301. The filter plates placed in the linear array 302 are in contact with each other in sequence, and the filter plate 302 is a V-shaped plate structure. The filter plate 302 is provided with a second filter hole 303 and a third filter hole 304 in a rectangular array.

[0052] Among them, two plug-in rods 306 are welded on the bottom end surface of each filter plate 302. The plug-in rod 306 is a cylindrical rod-shaped structure. The lower end of the plug-in rod 306 is polished. After polishing, the lower end of the plug-in rod 306 is an arc-shaped structure. The two plug-in rods 306 on the bottom end surface of each filter plate 302 are plugged into the support block 301. When installing the filter plate 302, the plug-in rod 306 and the support block 301 are plugged together to improve the stability of the installation of the filter plate 302. The filter plate 302 is prevented from being displaced under the impact of water flow, thereby ensuring the filtering effect of the filter plate 302; during the process of plugging the plug rod 306 with the support block 301, the lower end of the plug rod 306 is an arc structure, so the installation efficiency of the filter plate 302 can be improved; because a holding block 305 is welded on each filter plate 302, when installing and disassembling the filter plate 302, the holding block 305 can be held by hand to disassemble and assemble the filter plate 302, which is convenient for disassembly and assembly.

Compared with the drainage trough 1 only cast by cement, the strength is higher and there will be no problem of fracture affecting drainage; two first auxiliary blocks 102 are cast on the outside of the drainage trough 1. The two first auxiliary blocks 102 are pre-buried in the soil. During use, the two first auxiliary blocks 102 can prevent the drainage trough 1 from being displaced after being pre-buried. , thereby avoiding water loss due to displacement of the drainage trough 1, which in turn causes damage to the foundation; a second auxiliary block 103 is fixed on the inner wall of the drainage trough 1, and the second auxiliary block 103 is made of metal. The second auxiliary block 103 is a concave block structure, and the bottom end face, left end face and right end face of the second auxiliary block 103 are respectively in contact with the bottom end face, left end face and right end face of the inner wall of the drainage trough 1.

The setting of the mounting frame 401 can ensure the normal downward flow of water. Two rectangular block-shaped guide plates 402 are welded on the top surface of the mounting frame 401. The two guide plates 402 are welded in an inclined shape. The guide plates 402 welded in an inclined shape still have a certain discharge capacity when the subsequent closing plate 404 is separated from the guide plates 402. The two guide plates 402 are mirror-shaped. The two guide plates 402 are arranged in a shape of a figure, and are located below the filter plate 302.

The closing plate 404 is an inverted V-shaped structure. When the two first electric cylinders 403 are extended to the maximum length, the closing plate 404 and the two guide plates 402 are spliced. During use, external moisture is filtered through the first filter hole 201 and the second filter hole 303 and then contacts the closing plate 404 and the two guide plates 402. At this time, the moisture can be discharged through the closing plate 404 and the two guide plates 402.
