Description

Technical Field

[0001] This utility model relates to the field of dam seepage prevention and water stopping technology, and in particular to an adaptive water-stop strip for seepage prevention at concrete dam joints. Background Technology

[0002] A concrete dam is a dam structure built primarily of concrete. It is widely used in water conservancy projects. The most important function of a concrete dam is to impound water, thereby blocking water flow, raising water levels, forming a reservoir, and providing water for irrigation, power generation, and water supply. At the same time, by regulating the water storage capacity of the reservoir, it can impound floodwaters during flood season, reduce peak flow, and mitigate flood disasters in downstream areas. Among these, the dam's seepage prevention and water sealing are key aspects to ensure the safe operation of the dam and prevent water leakage.

[0003] Water-stopping devices are installed at the joints of the dam body, such as horizontal and longitudinal joints, to prevent water from seeping through the gaps. Water-stopping joints are made of water-stopping strips and water-stopping tape, combined with sealant for sealing. The installation process of some water-stopping strips is quite complicated, requiring professional construction personnel and special construction equipment, which increases the difficulty and cost of construction. The current solution is to use pre-formed water-stopping strips. Pre-formed water-stopping strips can be pre-processed into specific shapes and sizes according to project needs, and can be directly positioned and fixed on site, improving construction efficiency. However, the water-stopping strips still suffer from local damage or aging and cracking during long-term use due to the influence of water pressure, temperature changes and structural deformation, resulting in a decrease in water-stopping effect. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an adaptive waterstop for seepage prevention at concrete dam joints, aiming to improve the waterstop effect in existing technologies during long-term use due to the influence of water pressure, temperature changes, and structural deformation.

[0021] 1. In this utility model, a thermoplastic elastic layer is used as the base layer of the waterstop, which improves the waterstop's adaptability to deformation. Due to its good elasticity and flexibility, it can deform along with the dam body when it deforms, maintaining the waterstop effect.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an adaptive waterstop for seepage prevention at concrete dam joints, comprising an outer plate 1, with a thermoplastic elastic layer 3 fixedly connected to the inner bottom wall of the outer plate 1. The thermoplastic elastic layer 3 serves as the base layer of the waterstop, thereby improving the waterstop's adaptability to deformation. As a result, the waterstop deforms along with the dam body when it deforms, maintaining the waterstop effect. A tear-resistant layer 5 is fixedly connected to the top wall of the thermoplastic elastic layer 3, which increases the internal strength of the waterstop. Multiple high-strength rubber strips 6 are fixedly connected to the front side of the inner wall of the tear-resistant layer 5, and multiple connecting ribs 7 are fixedly connected to the left side of the inner wall of the tear-resistant layer 5. Subsequently, the tear resistance of the waterstop is further improved by the connection between the high-strength rubber strips 6 and the connecting ribs 7. A gel plate 8 is fixedly connected to the top wall of the tear-resistant layer 5, and a weathering mechanism 2 is provided on the top wall of the gel plate 8 to improve the weather resistance of the waterstop.

[0032] Specifically, a thermoplastic elastic layer 3 is fixedly connected to the inner bottom wall of the outer plate 1. As the base layer of the waterstop, it gives the waterstop good adaptability to deformation. When the dam body deforms, the waterstop can deform accordingly and maintain the waterstop effect. The top wall of the thermoplastic elastic layer 3 is connected to a tear-resistant layer 5 to enhance the internal strength of the waterstop. Multiple high-strength rubber strips 6 are fixed at equal intervals on the front side of the inner wall of the tear-resistant layer 5, and multiple connecting ribs 7 are fixed on the left side of the inner wall. The two work together to further improve the tear resistance of the waterstop. The top wall of the tear-resistant layer 5 is connected to a gel plate 8, which further improves the heat insulation effect of the waterstop. The structure of the waterstop is improved, and the local damage or aging cracking caused by external influences is reduced.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The weather-resistant mechanism 2 includes a waterproof membrane 201. The bottom wall of the waterproof membrane 201 is fixedly connected to the top of the gel plate 8. The waterproof membrane 201 improves the waterproof effect inside the waterstop. A silicone sealant layer 203 is fixedly connected to the top of the waterproof membrane 201. The silicone sealant layer 203 further improves the sealing of the waterstop and reduces the penetration of external water vapor. Multiple rock wool boards 204 are fixedly connected to the top of the silicone sealant layer 203. The connection between the rock wool boards 204 and the waterproof membrane 201 increases the weather resistance of the waterstop. Multiple stress grooves 205 are provided on the top wall of the rock wool boards 204. The stress grooves 205 can further reduce the damage to the inside of the rock wool boards 204 caused by stress accumulation.

[0034] Specifically, the waterproof membrane 201 is fixed to the top of the gel board 8 to enhance the internal waterproof performance of the waterstop. The top of the waterproof membrane 201 is connected to the silicone sealant layer 203 to further improve the sealing performance of the waterstop and effectively block the penetration of external water vapor. Multiple rock wool boards 204 are fixed to the top of the silicone sealant layer 203. The rock wool boards 204 and the waterproof membrane 201 work together to improve the weather resistance of the waterstop and make it adaptable to different environmental conditions. Multiple stress grooves 205 are opened on the top wall of the rock wool board 204. When the waterstop is deformed under stress, the stress grooves 205 can disperse the stress and reduce the damage caused by stress accumulation to the rock wool board 204.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The weather-resistant structure 2 also includes multiple UV-resistant layers 206, the bottom walls of which are fixedly connected to the top wall of the outer panel 1; the top wall of the waterproof membrane 201 is provided with multiple arc-shaped grooves 202, which are spaced apart; the bottom of the thermoplastic elastic layer 3 is fixedly connected with multiple buffer pads 4, which are all cylindrical in design.

[0036] Specifically, the UV-resistant layer 206 enhances the UV resistance of the waterstop's exterior. The multiple arc-shaped grooves 202 effectively increase the toughness of the waterproof membrane 201, extending its service life. The multiple buffer pads 4 reduce damage to the bottom of the waterstop at the installation location.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Multiple high-strength rubber strips 6 are fixedly connected to each other and to the outer walls of multiple connecting ribs 7, forming a rectangular grid design; multiple wear-resistant columns 9 are fixedly connected to the upper and lower sides of the outer plate 1, and the multiple wear-resistant columns 9 are all symmetrically designed; multiple pressure-resistant rings 10 are fixedly connected to the middle of the upper and lower sides of the outer plate 1, and the outer walls of the multiple pressure-resistant rings 10 are all smooth.

[0038] Specifically, the high-strength rubber strip 6 is fixedly connected to multiple connecting ribs 7 to form a grid structure, which improves the toughness of the tear-resistant layer 5 and enhances the tear resistance. The connection of the wear-resistant columns 9 enhances the protection effect of the waterstop during use. The connection of multiple pressure-resistant rings 10 reduces external pressure damage to the middle of the waterstop.

[0039] Working principle: The thermoplastic elastic layer 3 is fixedly connected to the inner bottom wall of the outer plate 1 as the base layer of the waterstop. Utilizing its elasticity and flexibility, the waterstop has good adaptability to deformation. When the dam body deforms, the thermoplastic elastic layer 3 can deform accordingly, ensuring that the overall structure of the waterstop is not damaged and the waterstop effect is maintained continuously. The tear-resistant layer 5 connected to the top wall of the thermoplastic elastic layer 3 is made of fiber-reinforced material and rubber composite, which effectively improves the overall strength of the waterstop. Multiple high-strength rubber strips 6 and multiple connecting ribs 7 together form a reinforced structural network, which improves the internal toughness of the tear-resistant layer 5. The high-strength rubber strips 6 provide local tensile strength, while the connecting ribs 7 enhance the connection stability of the overall structure. The synergistic effect of the two further improves the tear resistance of the waterstop and reduces the risk of local damage, aging and cracking of the waterstop due to external factors. The gel plate 8 fixed to the top wall of the tear-resistant layer 5 completes the structural composition of the waterstop and provides a basic connection surface for the subsequent functional layer, thereby reducing the impact of external changes on the waterstop.

[0040] Furthermore, the bottom wall of the waterproof membrane 201 is fixed to the top of the gel board 8. With its dense structure and waterproof properties, it forms a waterproof barrier inside the waterstop, preventing water penetration. The silicone sealant layer 203 connected to the top of the waterproof membrane 201, with its excellent adhesion and sealing performance, fills the tiny gaps above the waterproof membrane 201, further enhancing the internal sealing of the waterstop and effectively preventing external moisture from seeping in, thus avoiding the impact of moisture erosion on the service life of the waterstop. Multiple rock wool boards 204 are fixed to the top of the silicone sealant layer 203. The rock wool boards 204 have good temperature resistance and anti-aging properties. Working in synergy with waterproof membrane 201, it resists the erosion of the waterstop by ultraviolet rays and changes in high and low temperatures, significantly improving the weather resistance of the waterstop. At the same time, the multiple stress grooves 205 opened on the top wall of the rock wool board 204 can disperse the internal stress generated by the stretching and compression operations during the installation of the waterstop, preventing stress concentration from damaging the rock wool board 204. During the use of the waterstop, when subjected to stress caused by changes in the external environment or structural deformation, the stress grooves 205 can also play a buffering role to avoid excessive stress accumulation, thereby extending the overall service life of the waterstop.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
