Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, in particular to a wave-shaped water diversion ditch. Background Art

[0002] my country's water resources are unevenly distributed in time and space, and their availability is mismatched with socioeconomic development levels. This creates a significant imbalance between water supply and demand, and many regions are unable to fully address water shortages simply by tapping into their own water resource potential. This problem is particularly acute in small watersheds, which, due to their small catchment areas and rapidly flowing rivers, have minimal capacity to regulate and store water.

[0003] As a water resource allocation project, diversion ditches are widely used in water resource development and utilization. Their primary function is to address the spatial and temporal heterogeneity of water resources. From the perspectives of optimizing the spatial and temporal allocation of regional water resources, improving water resource development and utilization efficiency, and enhancing water resource security for water users, diversion ditches are a common type of engineering in the development and utilization of water resources in small watersheds. For example, they are needed for regional irrigation, water supply, power generation, and water ecological improvement.

[0004] However, the cross-sectional area of ​​the existing water diversion ditch is the same throughout the ditch. During the water diversion process, suspended particles such as sediment in the water cannot be precipitated, and the ditch has no ability to purify the water quality.

[0005] Therefore, the present application proposes a wave-shaped water diversion ditch. Utility Model Content

[0006] The purpose of this utility model is to propose a wavy water diversion ditch, change the cross-sectional shape of the ditch to affect the behavior of the water flow, reduce the risk of blockage of the back-end system, increase the contact oxidation purification of the water body, facilitate solar ultraviolet radiation exposure, achieve a sterilization effect, reduce E. coli in the water body, and at the same time provide a living environment for benthic animals, improve biodiversity, build underwater forests, and enhance the water purification capacity of the ditch.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The wavy water diversion ditch includes a sedimentation zone, a shallow water energy exchange zone and a biodiversity zone. A sedimentation zone is set at the water inlet of the ditch, and shallow water energy exchange zones and biodiversity zones are alternately set behind the sedimentation zone.

[0009] Furthermore, the sedimentation zone and the biodiversity zone are concavely arranged, and the depths of the sedimentation zone and the biodiversity zone are consistent.

[0010] Furthermore, the shallow water energy exchange area is provided with corrugated protrusions, and the distance between two adjacent protrusions is consistent.

[0011] Furthermore, the sedimentation area includes a plain soil layer, a crushed stone layer and a concrete layer from bottom to top, and the thickness of the crushed stone layer and the concrete layer are consistent.

[0012] Furthermore, the shallow water energy exchange area includes a plain soil layer at the bottom, and a rubble stone layer is laid on the plain soil layer.

[0013] Furthermore, planting soil is provided in the biodiversity area.

[0014] Furthermore, the lengths of the sedimentation zone and the biodiversity zone are consistent, and the length of the shallow water energy exchange zone is greater than that of the sedimentation zone and the biodiversity zone.

[0015] The utility model has at least one of the following beneficial effects:

[0016] The main principle of the wavy water diversion ditch is based on relevant theories such as fluid dynamics and drag reduction technology. It affects the behavior of water flow by changing the cross-sectional shape of the ditch. It has the following main functions:

[0017] ① Regulation and control: The wavy ditch design can form a more complex flow velocity distribution, which helps to effectively control and regulate the water flow in different sections, and avoid the impact of large water volume and high flow rate on the back-end system.

[0018] ② Energy dissipation: disperse the impact of water flow, reduce scouring effects, and thus protect the stability of the ditch structure.

[0019] ③ Sand settling: When the water flow carries a large amount of sediment, gravity is used to settle the sediment, reducing the amount of sediment entering the back-end system and reducing the risk of blockage.

[0020] ④ Biodiversity: The intersection of deep and shallow ditches can increase the oxygen content of the water through energy exchange, waterfall aeration, etc., which helps maintain the diversity of the ecosystem and promote the growth and reproduction of aquatic organisms.

[0021] ⑤ Improved purification capacity: It can increase the contact area between water flow and riverbed, which helps to increase the chance of water flow contact with air, bottom sediment, etc., thereby promoting the exchange of dissolved oxygen in the water body, promoting the precipitation and decomposition of pollutants in the water, and at the same time is conducive to solar ultraviolet radiation exposure to achieve a sterilization effect, reduce E. coli in the water body, and enhance the self-purification ability of the water flow.

[0022] ⑥ Better landscape effect: It can serve as a unique landscape element, adding a sense of dynamism and beauty to the surrounding environment and enhancing the overall landscape effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Example

[0027] The wavy water diversion ditch includes a sedimentation zone 1, a shallow water energy exchange zone 2 and a biodiversity zone 3. The sedimentation zone 1 is set at the water inlet of the ditch, and the shallow water energy exchange zone 2 and the biodiversity zone 3 are alternately set behind the sedimentation zone 1.

[0028] The sedimentation area 1 and the biodiversity area 3 are concave, and the depths of the sedimentation area 1 and the biodiversity area 3 are consistent.

[0029] Among them, corrugated protrusions 4 are provided on the shallow water energy exchange area 2, and the distance between two adjacent protrusions 4 is consistent. The natural oxygen enrichment and natural waterfall in the shallow water energy exchange area 2 can increase the contact oxidation purification of the water body, and can realize the artificial strengthening of the biofilm growing on the gravel surface. At the same time, the shallow water area is conducive to solar ultraviolet radiation exposure, which achieves the effect of sterilization and reduces E. coli in the water body.

[0030] The sedimentation area 1 includes a plain soil layer, a crushed stone layer and a concrete layer from bottom to top, and the thickness of the crushed stone layer and the concrete layer are the same.

[0031] The shallow water energy exchange area 2 includes a plain soil layer at the bottom, on which a rubble stone layer is laid.

[0032] Among them, planting soil is set up in biodiversity area 3, which is mainly used to restore submerged plants. At the same time, it can provide a living environment for benthic animals, improve biodiversity, build underwater forests, and enhance the water purification capacity of ditches.

[0033] The lengths of sedimentation zone 1 and biodiversity zone 3 are the same. Sedimentation zone 1 is mainly used to settle suspended particles such as sediment in the incoming water to reduce the risk of blockage in the back-end system. To facilitate the subsequent cleaning of sediment, a plain concrete structure is used. The length of shallow water energy exchange zone 2 is greater than that of sedimentation zone 1 and biodiversity zone 3.
