As an important carrier for agricultural irrigation, urban water supply, and ecological water replenishment, the leakage problem of river diversion canals directly leads to water waste and reduced water conveyance efficiency.
[0003] The seepage prevention structure of the water diversion canal in water conservancy projects consists of a seepage prevention layer, a protective layer, a drainage system, and foundation treatment components. It blocks seepage through the low permeability of materials, drains water through the drainage system, maintains stability through foundation treatment and the protective layer, and coordinates the ecological environment with the filter layer and vegetation protection to achieve seepage prevention and water transport.
[0004] In existing technologies, some water diversion canals require on-site customized construction in areas with complex terrain, which involves complicated procedures, increased manpower input, and longer construction periods compared to modular structures. It is also difficult to flexibly adjust the length and direction of the canal through modular splicing. If there are elevation differences or bends in the riverbed, the overall structure needs to be redesigned, or even the already constructed parts need to be damaged, resulting in material waste. Long-term leakage leads to water resource waste and exacerbates regional water shortages. Therefore, a seepage prevention structure for water diversion canals in water conservancy projects is proposed to solve the above problems. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figures 1 to 3This utility model provides an embodiment of a seepage-proof structure for a river diversion canal in water conservancy engineering, including a river frame 1. Two connecting plates 2 are installed on the top of the river frame 1. The stable structure of the river frame 1 can withstand the water flow pressure, soil pressure, and the weight of each component during the operation of the diversion canal, ensuring the stability of the entire seepage-proof structure and serving as the foundation for the entire diversion canal seepage-proof system. Telescopic rods 4 are fixedly connected inside each connecting plate 2. The connecting plates 2, in conjunction with connecting plates 3, enable rapid splicing and provide installation positions for sealing strips 8, ensuring the sealing of the splice. Springs 5 are fixedly connected inside each of the fixing blocks 6. The elasticity of the springs 5 allows the fixing blocks 6 to fit tightly against the connecting plate 2 3, enhancing the connection strength at the joint and buffering external impacts to a certain extent, protecting the spliced structure. The rear side of the springs 5 is fixedly connected to the front side of the fixing blocks 6. The main function of the fixing blocks 6 is to connect the springs 5 and the connecting plate 2 3, cooperate with the slots 9 to achieve splicing, and provide a threaded connection for the bolts 11 to ensure the stability of the spliced structure. The telescopic rod 4 is sleeved inside the springs 5. The telescopic rod 4 provides support for the forward and backward movement of the fixing blocks 6, ensuring that the fixing blocks 6 are stable within the connecting plate 2. The sliding mechanism facilitates a smoother assembly process. Each spring 5 has a fixed block 6 attached to its rear side. Each fixed block 6 has two square sliders 7 fixedly connected to its exterior. These sliders restrict the movement of the fixed block 6, preventing it from shifting or wobbling during movement. This ensures that the fixed block 6 accurately engages with the slots 9 of the connecting plate 2, enabling rapid assembly. The square sliders 7 are externally slidably connected to the interior of the connecting plate 2. The fixed block 6 is externally slidably connected to the connecting plate 2, which secures it to the plate. The internal slots 9 engage with the fixed block 6, restricting its movement during assembly. To ensure splicing accuracy and stability, bolts 11 are threaded onto the exterior of connecting plate 2 3. Bolts 11 prevent the spliced connecting plate 2 3 from separating due to external forces, enhancing the stability and reliability of the splicing structure. Sealing strips 8 are fixedly connected to the rear side of connecting plate 2 3. Sealing strips 8 fill the splicing gaps, preventing water leakage from the splicing point, enhancing the sealing of the seepage prevention structure, and ensuring the seepage prevention effect of the water diversion channel. The external threads of bolts 11 are connected to the interior of fixing block 6. A slot 9 is provided inside connecting plate 2 3 to ensure accurate docking between connecting plate 2 3 and connecting plate 2 3. At the same time, the design of slot 9 makes the splicing process more convenient and improves splicing efficiency. A waterproof seepage prevention component 10 is installed on the top of the river frame 1. Reference Figure 4 , Figure 5The top of the channel frame 1 is equipped with a connecting plate 13, which is fixed to the connecting plate 14 by bolts 16, providing an installation position for the sealing strip 12 and ensuring the seepage prevention performance of the overall splice of the channel frame 1. The top of the channel frame 1 is equipped with a connecting plate 14, the main function of which is to splice with the connecting plate 13 to extend or connect the channel frame 1. The connection is ensured to be stable and airtight through the limiting and sealing structure. Two limiting plates 15 are fixedly connected to the front side of the connecting plate 14 to prevent misalignment of the connecting plate 13 and the connecting plate 14 during the splicing process. To ensure the accuracy and stability of the connection, the external threaded connection of the limiting plate 15 has two bolts 16. Bolts 16 provide strong fastening force, connecting the different parts of the river frame 1 into a whole, enhancing the structural strength and stability. The external thread of bolts 16 is connected to the inside of the connecting plate 13. The front side of the connecting plate 14 is fixedly connected to a sealing strip 12. The sealing strip 12 is in close contact with the rear side of the connecting plate 13, filling the gap at the joint, preventing water leakage, and ensuring the sealing of the splice of the different parts of the river frame 1. The front side of the sealing strip 12 is in contact with the rear side of the connecting plate 13.
[0013] Reference Figure 1 , Figure 6 The seepage prevention component 10 includes a seepage prevention layer 17. The seepage prevention layer 17 is made of a material with an extremely low permeability coefficient, which can effectively block water from passing through. It is a key barrier to prevent water from seeping into the ground in the water diversion channel, ensuring the effective transportation of water resources. A grouting layer 18 is fixedly connected to the outside of the seepage prevention layer 17. The grouting layer 18 can improve the overall strength of the seepage prevention structure, make up for any weak points in the seepage prevention layer 17, and further improve the seepage prevention effect. A seepage prevention mortar layer 19 is fixedly connected to the outside of the grouting layer 18. The seepage prevention mortar layer 19 provides a flat base layer for the protective layer 20, enhances the durability and erosion resistance of the seepage prevention structure, and the protective layer 20 is fixedly connected to the outside of the seepage prevention mortar layer 19. The protective layer 20 prevents it from being damaged by external forces such as water flow erosion, soil friction, and mechanical damage, extends the service life of the seepage prevention structure, and ensures the long-term stable operation of the water diversion channel.
[0014] Working principle: The river frame 1 serves as the load-bearing foundation, resisting water flow, soil pressure, and component weight to ensure structural stability. Connecting plate 1 2 and connecting plate 2 3 are spliced together by fixing block 6, slot 9, and bolt 1 11. Spring 5 provides elasticity to keep fixing block 6 in contact with connecting plate 2 3. Telescopic rod 4 provides guidance, and square slider 7 provides limit, ensuring splicing accuracy and efficiency. Sealing strip 1 8 fills the splicing gap between connecting plate 1 2 and connecting plate 2 3. Connecting plate 1 13 and connecting plate 2 14 are fixed by bolt 2 16. Limiting plate 15 prevents misalignment. Sealing strip 2 12 seals the joint. The multi-layer structure of the seepage prevention component 10 further prevents water seepage, jointly ensuring the seepage prevention effect of the water diversion channel. It can achieve rapid positioning and connection, reduce construction waiting time, and speed up project progress. It is especially suitable for projects with tight schedules, reducing quality problems caused by improper manual operation, such as excessive gaps and poor sealing, thereby improving the overall quality of the seepage prevention structure.
[0015] The impermeable layer 17, made of a low-permeability material, directly blocks water penetration, serving as the core barrier to prevent water leakage within the irrigation canal and ensuring no loss of water resources during transport. The grouting layer 18 wraps around the impermeable layer 17, filling gaps, enhancing the overall structural strength, and further improving impermeability. The impermeable mortar layer 19 covers the grouting layer 18, providing a smooth base layer, enhancing structural durability and erosion resistance, and laying the foundation for the protective layer 20. As the outermost layer, the protective layer 20 resists water erosion, soil friction, and mechanical damage, protecting the internal structure, extending the service life of the impermeable components 10, ensuring the long-term stable operation of the irrigation canal, effectively preventing water leakage from the irrigation canal into the surrounding soil, ensuring the integrity of water resources during transport, avoiding water loss due to leakage, improving water resource utilization efficiency, reducing maintenance work such as canal repair and foundation reinforcement caused by leakage, extending the service life of the irrigation canal, and reducing project operation and maintenance costs in the long run.
