Description

Technical Field

[0001] This utility model belongs to the field of dam seepage prevention technology, and in particular relates to a dam seepage prevention device. Background Technology

[0002] A dam is a general term encompassing both dikes and dams, and also refers to structures and buildings used for waterproofing and water control. Modern dams are mainly divided into two categories: earth-rock dams and concrete dams. In recent years, large dams have adopted high-tech reinforced concrete construction. Dams are generally composed of concrete and gravel, with sloping sides. Over time, these slopes are eroded by water, leading to erosion and seepage. Therefore, it is necessary to install dam reinforcement and seepage control devices to strengthen the dam.

[0003] Most existing dam seepage prevention devices use threaded cones and ground nails to directly fix the seepage prevention plate inside the dam. This method has certain shortcomings in actual use: the seepage prevention plate is in direct contact with the dam surface, and cannot mitigate the impact when subjected to water. Long-term use will cause the seepage prevention plate to be damaged and cracked, losing its seepage prevention ability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a seepage prevention device for dikes, and the technical solution adopted is as follows:

[0005] A seepage prevention device for a dam includes a concrete layer poured on the surface of the dam, a plurality of connecting frames are provided in the concrete layer, a pad is provided between adjacent connecting frames, a panel is laid between adjacent connecting frames and on the outer side of the pad, and a clamping frame is installed between adjacent panels after the panels are laid.

[0006] Furthermore, the sum of the thicknesses of the pad and the panel is greater than the length of the connecting frame protruding from the concrete layer, and a sealing gasket is embedded between adjacent panels and on the outside of the connecting frame; the thickness of the sealing gasket plus the length of the connecting frame protruding from the concrete layer is greater than the sum of the thicknesses of the pad and the panel, and the sealing gasket protruding from the panel surface can be fully filled between adjacent panels under the installation compression of the clamping frame.

[0007] Furthermore, multiple studs are provided on the outer side of each connecting frame from top to bottom, and openings for the studs to pass through are provided in both the card holder and the sealing gasket. After the sealing gasket and the card holder are placed in place, the card holder can be installed and fixed by connecting the nuts and studs.

[0008] Furthermore, to ensure that the panel can be firmly fixed after the card holder is installed, the card holder adopts a U-shaped structure, with card slots on both sides of the panel that allow one end of the card holder to be inserted.

[0009] Furthermore, a groove is provided on both sides of the pad, which engages with the extension plate in the middle of the connecting frame.

[0010] Furthermore, the pad is made of a rubber sheet or foam board with a certain degree of elasticity, which can provide a flat, dense and elastic foundation for the panel, absorb the impact of water flow, and extend the service life of the panel.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention involves sequentially laying a concrete layer, a base plate, and a panel on the surface of a dam. By arranging several panels in sequence, water flow can be blocked, reducing water infiltration. The base plate provides a flat, dense, and elastic foundation for the panel, and the interlocking between the base plate and the connecting frame further blocks water penetration, thus achieving a good seepage prevention effect. Furthermore, the flat concrete layer protects the base plate from damage and also fixes the connecting frame, allowing the entire device to be firmly installed on the dam surface, meeting the needs of long-term use.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As attached Figure 1-3 As shown.

[0020] A dam seepage prevention device includes a concrete layer 2 poured on the surface of the dam 1. There are multiple connecting frames 3 in the shape of "soil" in the concrete layer 2. A backing plate 4 is arranged between adjacent connecting frames 3. A panel 5 is laid on the outer side of the backing plate 4 between adjacent connecting frames 3. After the panel 5 is laid, a clamping plate frame 6 is installed between adjacent panels 5.

[0021] To achieve the overall sealing of the device, the sum of the thicknesses of the backing plate 4 and the panel 5 is greater than the length of the connecting frame 3 protruding from the concrete layer 2. Therefore, a sealing gasket 7 is embedded between adjacent panels 5 and on the outer side of the connecting frame 3. An opening for the stud 31 to pass through is also provided in the sealing gasket 7, and the sum of the thickness of the sealing gasket 7 and the length of the connecting frame 3 protruding from the concrete layer 2 is slightly greater than the sum of the thicknesses of the backing plate 4 and the panel 5. Specifically, it can exceed the sum of the thicknesses of the backing plate 4 and the panel 5 by 0.5 - 1 cm. The sealing gasket 7 protruding from the surface of the panel 5 can be fully filled between the connected panels 5 under the installation and extrusion of the clamping plate frame 6, thus ensuring the overall seepage prevention of the panel.

[0022] A groove is provided on both sides of the backing plate 4, which is engaged with the extension plate at the middle position of the connecting frame 3, thereby realizing the installation of the backing plate 4. After the backing plate 4 is installed, the inner side surface of the backing plate 4 contacts the surface of the concrete layer 2. The flat concrete layer can protect the backing plate 4 from being damaged.

[0023] The installation process of this device is as follows: First, pour a layer of concrete layer 2 on the surface of the dam 1. When pouring the concrete layer 2, embed the connecting frame 3 into the specified position. After the concrete layer 2 is formed, install the backing plate 4 and the panel 5 in sequence. Finally, insert the sealing gasket 7 and fix it with the clamping plate frame 6.

[0024] After the clamping plate frame 6 is fixed, an anti-corrosion paint can be sprayed on the outer sides of the exposed studs and nuts to extend the service life of the studs and nuts.

[0025] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
