Description

Technical Field

[0001] This utility model relates to the field of ecological slope protection technology, specifically to a water conservancy ecological slope protection drainage structure. Background Technology

[0002] Ecological slope protection in water conservancy refers to slope protection techniques that combine vegetation measures with engineering measures in water conservancy projects, taking into account the needs of soil and water conservation, ecological protection, and engineering safety. Its core objective is to restore and improve the ecological environment around water bodies while ensuring the safety and stability of water conservancy facilities.

[0003] Existing water conservancy ecological slope protection structures are simply planted with some ecological plants, but drainage and seepage can still lead to soil erosion, especially in areas with high rainfall, where the soil used for planting crops will also suffer significant loss. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a water conservancy ecological slope protection and drainage structure that reduces water seepage and soil erosion, in view of the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a water conservancy ecological slope protection drainage structure, including a base layer, a concrete pouring layer on the top of the base layer, a drainage channel at the bottom of the concrete pouring layer, a planting layer on the inclined surface of the concrete pouring layer, and a concrete pouring partition plate on the inclined surface of the concrete pouring layer, the concrete pouring partition plate dividing the planting layer into multiple sections.

[0006] The concrete pouring layer contains a gravel layer located below the planting layer. The gravel layer is divided into a first gravel layer and a second gravel layer, which are set up one above the other. A waterproof layer is located below the second gravel layer in the concrete pouring layer. Drainage pipes extending into the drainage ditch are provided at the bottom of the first gravel layer and the second gravel layer.

[0007] Furthermore, a soil support net layer is provided at the bottom of the planting layer, and a support frame layer is provided between the soil support net layer and the first gravel layer to facilitate soil operations for supporting the planting layer.

[0008] Furthermore, the diameter of the first gravel layer is greater than 15mm, and the diameter of the second gravel layer is between 5mm and 10mm, which facilitates the stratified water filtration operation.

[0009] Furthermore, the top of the drainage ditch is equipped with a garbage filter screen, and one end of the top of the drainage pipe is equipped with a gravel filter screen to prevent foreign objects from entering the drainage ditch.

[0010] Furthermore, the waterproof layer includes a waterproof membrane layer, and the waterproof layer includes a first support net and a second support net disposed above and below the waterproof membrane layer, which can support the waterproof membrane layer from both above and below during operation.

[0011] Furthermore, the top and bottom of the concrete pouring layer are wrapped with metal strips, and plastic parts that are heat-fused and fixed to the outside of the metal strips are fixedly embedded therein, which can tighten and ensure the stable operation of the waterproof membrane layer.

[0012] The advantages of this utility model's water conservancy ecological slope protection drainage structure compared to existing technologies are as follows: This device can ensure the stable support of the planting layer by setting a concrete pouring partition plate on the outside of the planting layer of the ecological slope protection. At the same time, through the gravel layer and the water-proof layer, water can be filtered and water-proofed, thereby reducing the occurrence of seepage and soil erosion.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-4A water conservancy ecological slope protection drainage structure includes a base layer 1, a concrete pouring layer 2 on top of the base layer 1, a drainage ditch 3 at the bottom of the concrete pouring layer 2, a garbage filter frame 17 on top of the drainage ditch 3 to prevent large garbage from entering the drainage ditch 3, a planting layer 6 on the inclined surface of the concrete pouring layer 2, and a concrete pouring partition plate 5 on the inclined surface of the concrete pouring layer 2 to divide the planting layer 6 into multiple sections.

[0020] A gravel layer 4 is provided below the planting layer 6 within the concrete pouring layer 2. The gravel layer 4 is divided into a first gravel layer 9 and a second gravel layer 10, which are set at the top and bottom respectively. The diameter of the first gravel layer 9 is greater than 15mm, and the diameter of the second gravel layer 10 is between 5mm and 10mm. By setting the first gravel layer 9 and the second gravel layer 10 from large to small, most particles can be filtered out. A soil support net layer 7 is provided at the bottom of the planting layer 6. A support frame layer 8 is provided between the soil support net layer 7 and the first gravel layer 9. The soil support net layer 7 can prevent too much soil from entering the gravel layer 4.

[0021] A water-proof layer 11 is provided in the concrete pouring layer 2 below the second gravel layer 10. The bottom of the first gravel layer 9 and the second gravel layer 10 are provided with a drain pipe 18 extending into the drainage ditch 3. A gravel filter screen 19 is provided at the top end of the drain pipe 18. The drain pipe 18 is provided so that the water impermeable by the water-proof layer 11 can be discharged into the drainage ditch 3. The gravel filter screen 19 can prevent gravel from entering the drain pipe 18 and the drainage ditch 3.

[0022] The waterproof layer 11 includes a waterproof membrane layer 13, which can be a high-strength waterproof membrane such as a high-density polyethylene geomembrane or a linear low-density polyethylene geomembrane. The waterproof layer 11 includes a first support net 12 and a second support net 14 set above and below the waterproof membrane layer 13. The first support net 12 and the second support net 14 can reinforce and support the waterproof membrane layer 13. The top and bottom of the concrete pouring layer 2 are wrapped with metal strips 15. Plastic parts 16 that are heat-fused to the waterproof membrane layer 13 are fixedly embedded on the outside of the metal strips 15. The upper and lower fixed plastic parts 16, together with the heat-fused fixation to the waterproof membrane layer 13, can further ensure the stable operation of the waterproof membrane layer 13. At the same time, the first gravel layer 9 and the second gravel layer 10 filter fine particles, which can prevent particles in the seepage water from damaging the waterproof membrane layer 13.
