Description

Technical Field

[0001] This utility model relates to the field of water conservancy channel technology, and more specifically, to a seepage prevention and reinforcement structure for water conservancy engineering channels. Background Technology

[0002] Currently, canals in water conservancy projects are typically assembled using prefabricated modules to improve construction efficiency. However, the joints in this assembly method usually rely on cement mortar for sealing and reinforcement, which has several drawbacks. First, the bonding strength of cement mortar is relatively low. Long-term exposure to water erosion, settlement deformation, or temperature changes can easily lead to cracks or peeling, resulting in decreased joint strength and affecting the overall stability of the canal.

[0003] Secondly, shrinkage cracks may occur during the curing process of cement mortar, and uneven filling of the mortar during construction can easily create local voids, making the joints weak points prone to leakage. Once leakage occurs in the channel, it will not only reduce the efficiency of water transport, but may also affect the stability of the surrounding soil, and even lead to damage to the channel structure, increasing the cost of later maintenance. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example

[0033] The following description, in conjunction with specific embodiments, provides further details. Figures 1-6 As shown, this utility model is a seepage prevention and reinforcement structure for water conservancy engineering channels, including a connecting block 2. The connecting block 2 is made of stainless steel, which provides high corrosion resistance and mechanical strength, making it suitable for water conservancy engineering applications that are exposed to water flow environments for extended periods. The connecting block 2 has a U-shaped structure, which can be connected to the joint of the channel 1, effectively enhancing the structural strength of the connection and reducing the risk of structural loosening or leakage caused by water flow impact or settlement of the channel 1. Rubber plates 3 are embedded on both sides of the connecting block 2, fitting against the two channels 1. The rubber plates 3 are made of aging-resistant, highly elastic sealing material, which can maintain good sealing performance for a long time and adapt to deformation caused by water flow erosion and temperature changes.

[0034] The reinforcing block 4 adopts a hook-shaped structure and is welded to the bottom walls of both sides of the connecting block 2. The hook head 41 faces upward and is adapted to the hook groove 11 on the channel 1, thus forming a stable mechanical locking relationship during the splicing process. To prevent the reinforcing block 4 from loosening during use, hook grooves 11 adapted to the reinforcing block 4 are opened on both connecting channels 1. The bottom wall of the hook groove 11 is also integrally formed with a locking block 12. The hook head 41 of the reinforcing block 4 can form a locking relationship with the locking block 12, thereby improving the tensile strength and shear resistance of the overall structure. In addition, the reinforcing block 4 has a locking groove 42 adapted to the locking block 12. The locking groove 42 can further enhance the fixing effect of the hook-shaped structure, so that the connecting block 2 will not shift its position under the action of water flow, thus improving the long-term stability of the structure.

[0035] The outer side plate 5 adopts a U-shape, which can extend along the outer side wall of the channel 1 to form a stable contact relationship with the outer side wall of the channel 1, thereby improving the overall stability of the connecting block 2. The extended structure of the outer side plate 5 can also provide additional support at the connection point of the channel 1, preventing the channel 1 from deforming or misaligning due to external forces during long-term use.

[0036] Reference Figure 2 and Figure 3As shown, to further enhance the connection strength between the connecting block 2 and the channel 1 and improve the seepage prevention and sealing effect, both the connecting block 2 and the reinforcing block 4 have interconnected cavities 21. In practical applications, grout such as connecting adhesive or cement mortar can be injected into the cavity 21 through the grouting hole 22 on the top wall of the connecting block 2, thereby enhancing the fastening force between the connecting block 2 and the channel 1 and preventing loosening or leakage caused by long-term water flow. At the same time, to ensure that the grout can fully fill each connection part, a first overflow hole 421 communicating with the cavity 21 is opened in the groove 42, so that the grout can be evenly distributed after injection, improving the overall density and stability of the connection.

[0037] Furthermore, to optimize the flow path of the grout and ensure its more even distribution at key connection points, both the bottom wall of the locking block 12 and the top wall of the locking groove 42 are provided with connecting grooves 43, which are arranged intersectingly. This design effectively improves the fluidity of the sealant, ensuring that the grout flows smoothly to the mating surface of the connecting block 2 and the channel 1, forming a uniform sealing layer and thus improving the overall sealing performance. The structure of the intersecting connecting grooves 43 not only optimizes the flow path during the grouting process and reduces uneven sealing caused by fluid stagnation, but also enhances the structural stability after the grout has cured, making the connection between the channel 1 and the connecting block 2 more robust.

[0038] Reference Figure 2 As shown, a second overflow hole 241, communicating with the cavity 21, is further provided within the groove 24 where the rubber plate 3 is embedded in the mating block 2. This second overflow hole 241 is elongated, providing greater flow space after the slurry enters the groove 24, allowing the slurry to fully penetrate to the back of the rubber plate 3, thereby enhancing the connection stability of the rubber plate 3. Simultaneously, during the slurry curing process, a certain pushing force is applied to the rubber plate 3, making it fit more tightly against one side of the channel 1, further improving the sealing effect and preventing water from seeping into the connection area. This design not only enhances the fixing effect of the rubber plate 3 but also effectively improves the overall seepage prevention performance.

[0039] Reference Figure 5 and Figure 6 As shown, to further enhance the overall stability of the docking structure, top pressure plates 6 are welded and installed at both ends of the top wall of the outer side plate 5. It should be noted that the top pressure plates 6 are welded to the outer side plate 5 after the two channels 1 are installed. The top pressure plates 6 are L-shaped, and their structural design allows them to snap into the top and inner walls of the two channels 1, forming an additional clamping and fixing effect. The installation of the top pressure plates 6 effectively prevents cracking, misalignment, or deformation of the channels 1 due to water flow impact, temperature changes, or foundation settlement during long-term use, thereby improving the overall connection strength and durability.

[0040] The top pressure plate 6, outer side plate 5, and connecting block 2 are connected by welding or fasteners to form an integrated clamping structure. These components work together at the connection point of the two channels 1, firmly clamping and fixing the channels 1 in place. This design not only improves the overall structural integrity but also reduces connection failures that may result from uneven stress on individual components. Furthermore, the L-shaped top pressure plate 6 applies downward pressure to the top of the channels 1, improving connection sealing and preventing leakage caused by slight deformation of the channels 1.

[0041] In addition, a pin 8 is fixedly welded onto the top pressure plate 6. The pin 8 is inserted into the grouting hole 22 to better seal the grouting hole 22 later.

[0042] Furthermore, to ensure precise alignment of the top pressure plate 6 during installation and to further enhance overall stability, limit grooves 13 are provided on the top walls of both channels 1 near the connecting seam. The limit grooves 13 are square in shape. A limit block 61 is fixedly installed on the bottom wall of the top pressure plate 6, its size and shape matching the limit groove 13 to achieve a snap-fit ​​connection. After the limit block 61 is inserted into the limit groove 13, it effectively prevents the top pressure plate 6 from sliding or shifting, ensuring a tight connection of the structure and thus improving the shear resistance and long-term stability of the joint. In addition, the design of the limit groove 13 also makes the installation process more convenient, ensuring accurate positioning of each component, reducing errors, and improving construction efficiency.

[0043] Reference Figure 2 and Figure 3 As shown, angle steel strips 7 are welded to the two inner corners of the connecting block 2. The angle steel strips 7 have an L-shaped structure and are used to abut against and fit against the inner corner sidewalls of the two channels 1 to provide additional support and positioning. By fixing the angle steel strips 7, the fit stability between the connecting block 2 and the channel 1 can be further enhanced, preventing misalignment or loosening due to external forces and improving the overall connection strength.

[0044] To reduce the impact of water flow on the connection points and avoid localized damage caused by stress concentration, the inner edges of the angle steel bars 7 near the channel 1 are all rounded. This rounded corner design not only reduces resistance during water flow and minimizes the generation of localized eddies, but also effectively reduces stress concentration, improves the structure's impact resistance, and enhances durability. Furthermore, the rounded corner transition helps reduce siltation, lowers the maintenance difficulty inside the channel 1, and ensures smooth water flow.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
