Description

Technical Field

[0001] This utility model relates to the field of anti-seepage wall technology, specifically a concrete anti-seepage wall structure. Background Technology

[0002] A cutoff wall is a continuous wall constructed in loose permeable layers or earth-rock dams (weirs) to prevent seepage. Originating in Europe in the 1950s, cutoff wall technology has gained widespread application both domestically and internationally due to its reliable structure, excellent seepage prevention effect, adaptability to various geological conditions, ease of construction, and low cost. It is particularly effective in addressing seepage deformation issues such as dam foundation leakage, downstream soil erosion, and piping. In my country, cutoff walls are generally the first choice for seepage prevention in water conservancy projects and other projects with seepage pressure.

[0003] There is a joint between the two sections of the existing concrete cutoff wall. The current technology only applies sealant or cement to the joint, which results in poor structural strength. The cutoff wall may not be able to withstand large water and soil pressures, leading to cracks, deformation or even damage to the wall, thus losing its seepage prevention function and resulting in poor seepage prevention effect.

[0004] Therefore, we propose a concrete anti-seepage wall to solve the above problems. Utility Model Content

[0025] 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.

[0026] Example

[0027] like Figures 1-6As shown in the figure, an embodiment of the present invention provides a concrete anti-seepage wall structure, including a first concrete wall 1 and a second concrete wall 2. Both ends of the first concrete wall 1 and the second concrete wall 2 have pouring cavities 3. A reinforcing plate 4 is provided within the pouring cavity 3 between the first concrete wall 1 and the second concrete wall 2. Reinforcing strips 5 are symmetrically and fixedly connected to the front and rear side walls of the reinforcing plate 4. A set of reinforcing blocks 6 are uniformly fixedly connected to the outer side walls of the reinforcing strips 5. Outer plates 7 are provided at both ends of the joint between the first concrete wall 1 and the second concrete wall 2. Grooves 8 matching the outer plates 7 are provided on both ends of the front and rear side walls of the first concrete wall 1 and the second concrete wall 2. A first connecting part 9 is fixedly connected between the top ends of the outer plates 7. Two first snap-fit ​​parts 10 are symmetrically and fixedly connected to the inner side walls of the outer plates 7. The left and right ends of the first concrete wall 1 and the second concrete wall 2... The upper end face of each end is provided with an installation groove 11 that matches the first connecting part 9. The casting cavity 3 is filled with the first sealing filler 12. The outer ends of the first concrete wall 1 and the second concrete wall 2 are both fitted with an outer frame 13. The space between the outer frame 13 and the casting cavity 3 is filled with the second sealing filler 14. The reinforcing plate 4, reinforcing strip 5 and reinforcing block 6 enhance the connection strength between the first concrete wall 1 and the second concrete wall 2, making the two walls form a more stable overall structure. The outer plate 7 cooperates with the receiving groove in the groove 8 through the first snap-fit ​​part 10 and the first connecting part 9 cooperates with the installation groove 11, further reinforcing the joint of the two walls and preventing loosening or cracks at the joint. The first sealing filler 12 and the second sealing filler 14 are respectively filled in the casting cavity 3 and between the outer frame 13 and the casting cavity 3, which plays a good sealing role, prevents water penetration and improves the seepage prevention performance of the seepage prevention wall.

[0028] like Figure 2 and Figure 6 As shown, in some embodiments, a second snap-fit ​​part 15 is fixedly connected to the inner sidewall of the outer frame 13, and a second connecting part 16 is fixedly connected to the top of the outer frame 13; the second snap-fit ​​part 15 can snap-fit ​​with the concrete wall, increasing the stability of the installation of the outer frame 13 and facilitating installation; the second connecting part 16 facilitates the snap-fit ​​between the outer frame 13 and the concrete wall, making the assembly and installation of the entire anti-seepage wall structure convenient and improving the integrity and reliability of the structure.

[0029] like Figure 2 As shown, in some embodiments, the cross-sectional shape of the reinforcing block 6 is T-shaped, and the outer surfaces of the reinforcing plate 4, the reinforcing strip 5, and the reinforcing block 6 are all coated with anti-corrosion paint; the T-shaped reinforcing block 6 can provide a larger contact area and better support, further enhancing the reinforcement effect; the anti-corrosion paint can prevent the reinforcing plate 4, the reinforcing strip 5, and the reinforcing block 6 from being corroded, extend their service life, ensure the long-term stability of the reinforced structure, and thus maintain the overall performance of the seepage barrier wall.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the outer plate 7, the first snap-fit ​​part 10, and the first connecting part 9 are all made of stainless steel. Each groove 8 has a receiving groove that matches the first snap-fit ​​part 10. Stainless steel has good corrosion resistance and strength, which can ensure that the outer plate 7, the first snap-fit ​​part 10, and the first connecting part 9 are not easily damaged during long-term use, thus improving the reliability and durability of the structure. The receiving groove matches the first snap-fit ​​part 10, so that the outer plate 7 can be accurately and stably installed in the groove 8, ensuring the tight connection between the outer plate 7 and the concrete wall, and further enhancing the seepage prevention performance of the anti-seepage wall.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the first concrete wall 1 and the second concrete wall 2 are spaced apart, and the outer frame 13 is respectively set at the outer ends of the first concrete wall 1 and the second concrete wall 2. The spaced first concrete wall 1 and the second concrete wall 2 can increase the overall thickness of the anti-seepage wall and improve the anti-seepage capacity. The outer frame 13 is set at the outer end to protect and reinforce the two walls, preventing external forces from damaging the two walls. At the same time, the second sealing filler 14 between the outer frame 13 and the two walls can further enhance the sealing effect and ensure the anti-seepage performance of the anti-seepage wall.

[0032] like Figure 1 As shown, in some embodiments, the outer surfaces of the first concrete wall 1, the second concrete wall 2, the outer panel 7, and the outer frame 13 are on the same horizontal plane; this makes the entire anti-seepage wall structure appear flat, which is convenient for subsequent construction and use, such as laying a waterproof layer and carrying out ground decoration; at the same time, the flat outer surface also helps to reduce the accumulation of water on the surface, reduce the risk of water penetration, and further improve the anti-seepage effect of the anti-seepage wall.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
