Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically to a slope protection structure for ecological wetlands. Background Technology

[0002] Ecological ponds are generally used for advanced wastewater treatment, with low concentrations of pollutants in the influent; they are also known as advanced treatment ponds. An ecological pond is an ecological aquaculture method that utilizes the principles of natural ecosystems, using artificially constructed water bodies for cultivating aquatic plants and animals. The ecological pond and reservoir implementation plan aims to improve the efficiency and sustainable development of ecological pond aquaculture through scientific planning and rational layout, while protecting the aquatic ecological environment and promoting the healthy development of the aquaculture industry.

[0003] In the construction of ecological ponds, slope protection structures are essential to prevent the pond slopes from being eroded by rainwater and other factors, leading to collapses or landslides that could affect the overall structure of the pond. This also helps prevent soil erosion within the pond, improves the ecological environment, and ultimately facilitates ecological restoration and construction. Current slope protection technologies typically involve directly covering the pond with soil and planting grass. However, this method lacks sufficient stability and stabilization, making it susceptible to erosion and potential collapses or landslides. Utility Model Content

[0004] This utility model provides a slope protection structure for ecological wetlands to achieve stable and robust protection of the slopes of ecological ponds.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a slope protection structure for an ecological wetland is provided, including an ecological pond and an overflow weir. The innovation is that the inner side of the ecological pond, which is inclined outward, is a slope, the overflow weir is located outside the ecological pond and near the top of the slope, the bottom of the ecological pond near the slope is a transition section, and the slope and the transition section are provided with a composite geomembrane and a slope protection device from bottom to top.

[0006] Furthermore, the slope protection device includes ecological bags and vegetation bags. The ecological bags are laid on the slope section below 0.5m from the water surface and in the transition section, while the remaining parts of the slope are covered with vegetation bags.

[0007] Furthermore, the slope protection device includes geocells and a soil cover layer. The geocells are laid on the composite geomembrane on the slope surface, and each opening in the top of the geocell is fixed to the ground by oak piles. The geocells are backfilled with planting soil, and the soil cover layer is located on top of the geocells.

[0008] Furthermore, the slope protection device also includes ecological bags. The geocells cover the slope, and the topsoil layer covers the geocells. The ecological bags are laid in the transition section. The geocells have a size of 4m*0.15m.

[0009] Furthermore, the slope protection device also includes ecological bags. The geocells are located in the upper part of the slope, occupying 2 / 3 to 3 / 4 of the slope area, and the topsoil layer covers the geocells. The ecological bags are laid on the remaining parts and transition parts of the slope. The geocells have a size of 2m*0.15m.

[0010] Furthermore, the length of the oak stakes ranges from 50 to 80 cm, and the depth of penetration into the ground is 20 to 50 cm.

[0011] Furthermore, the geocell has a cell height of 150mm, a cell sheet thickness of ≥0.5mm, and a soil cover layer thickness of 5cm.

[0012] Furthermore, the amount of the composite geomembrane used is 600g / ㎡, and the width of the transition section is 1m.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) The slope protection structure of the ecological wetland of this utility model combines ecological bags and vegetation bags and ecological bags and geocells to ensure that the resulting slope protection device is stable and secure. It can prevent the slope from being eroded or collapsed or landslide, and also has ecological and aesthetic functions.

[0015] (2) The slope protection structure of the ecological wetland of this utility model includes a transition part set at the bottom of the pond. The transition part is equipped with an ecological bag that is resistant to acid and alkali, corrosion and freeze-thaw, and also has moisture resistance. It does not absorb water, and water will not damage the bag. The bag will not deform and is insoluble in polluted liquid. It truly achieves zero ecological pollution. At the same time, its strong erosion resistance plays a stabilizing role in slope protection and ensures the overall stability of the slope protection structure.

[0016] (3) The growth of plants inside the ecological bags and vegetation bags can improve the surrounding environment and increase the vegetation coverage of the slope. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0022] This utility model provides a slope protection structure for an ecological wetland, including an ecological pond 1 and an overflow weir 2. The inner side of the ecological pond, which is inclined outward, is a slope 3. The overflow weir is located outside the ecological pond and near the top of the slope. The bottom of the ecological pond, near the slope, is a transition section 4. The slope and the transition section are provided with a composite geomembrane 5 and a slope protection device from bottom to top. Preferably, the amount of composite geomembrane used is 600g / ㎡. Example 1

[0023] The slope protection device in this embodiment includes ecological bags 6 and vegetation bags 7, such as Figure 1 As shown, ecological bags 6 are laid on the slope section below 0.5m from the waterline and in the transition section 4, while vegetation bags 7 are laid on the remaining parts of the slope 3. Due to the different raw materials and uses of ecological bags 6 and vegetation bags 7, the material of ecological bags 6 gives them the characteristics of being UV resistant, corrosion resistant, non-degradable, and highly erosion resistant, while vegetation bags 7 do not have the above characteristics. This makes the slope 3 with ecological bags 6 more likely to bear the load than the slope with vegetation bags 7. Vegetation bags 7 can only be used on general slopes with low requirements for structure and stability. Therefore, the arrangement of ecological bags 6 and vegetation bags 7 in this embodiment can largely satisfy the stability and durability of the slope protection device.

[0024] The slope protection device of this embodiment is more suitable for slope protection of ecological ponds that are plant oxidation ponds. The slope 3 of such ecological ponds is subject to greater erosion by water flow, and the foundation pit is relatively deep. The slope protection device of this embodiment has strong erosion resistance. Example 2

[0025] The slope protection device in this embodiment includes geocells 8 and a soil cover layer 9. The geocells 8 are laid on the composite geomembrane 5 on the surface of the slope 3, and each hole at the top of the geocell is fixed by oak piles 10 driven into the ground. After fixing, the oak piles 10 are covered by planting soil, and planting soil is also backfilled inside the geocells 8 to enhance the stability of the geocell slope protection.

[0026] The slope protection device also includes eco-bags 6, geocells 8 covering the slope 3, and a soil layer 9 covering the top of the geocells 8. The eco-bags 6 are laid in the transition section 4 for slope protection. In this embodiment, the geocells 8 have dimensions of 4m * 0.15m.

[0027] The slope protection device in this embodiment is more suitable for slope protection of ecological ponds that are facultative ponds. Example 3

[0028] In this embodiment, the slope protection device includes geocells 8 and a soil cover layer 9. The geocells 8 are laid on the composite geomembrane 5 on the surface of the slope 3, and each opening in the top of the geocell 8 is fixed to the ground by oak piles 10. After fixing, the oak piles 1 are covered with planting soil, and the geocells 8 are also backfilled with planting soil to enhance the stability of the slope protection provided by the geocells 8.

[0029] The slope protection device also includes an eco-bag 6, a geocell 8 located in the upper part of the slope 3, occupying 2 / 3-3 / 4 of the slope 3, and a soil layer 9 covering the top of the geocell 8. The eco-bag 6 is laid on the remaining part of the slope 3 and the transition part 4. The geocell 8 has a size of 2m*0.15m.

[0030] Since aerobic ponds and aquatic plant ponds are relatively shallow, the requirements for slope stabilization are not as high as for facultative ponds. Therefore, the slope protection device in this embodiment is more suitable for slope protection of ecological ponds that are aerobic ponds and aquatic plant ponds.

[0031] In Examples 2 and 3, the length of the oak stake 10 ranges from 50 to 80 cm, and the depth of the stake driven into the ground is 20 to 50 cm.

[0032] The geocell 8 has a cell height of 150mm, a cell sheet thickness of ≥0.5mm, a soil cover layer 9 thickness of 5cm, a longitudinal tensile yield strength of ≥150MPa, a tensile strength at the rivet of ≥100N / cm, and a cell sheet elongation (longitudinal) of ≤15%.

[0033] In this embodiment, the width of the transition section 4 in Examples 1-3 is 1m. The transition section 4 is equipped with an ecological bag 6 that is resistant to acids and alkalis, corrosion, and freeze-thaw cycles. It is also moisture-resistant, does not absorb water, and water will not damage the bag or deform it. It is insoluble in polluted liquids, truly achieving zero ecological pollution. At the same time, its strong erosion resistance plays a stabilizing role in slope protection and ensures the overall stability of the slope protection structure.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
