[0001] This utility model relates to the technical field of concrete sheet pile devices, specifically a reinforced concrete sheet pile with a water-stopping structure. Background Technology

[0002] Reinforced concrete sheet piles with water-stopping structures are widely used components in fields such as foundation pit protection and water conservancy projects. They are usually made of reinforced concrete, mostly U-shaped, and have high strength and rigidity. They can withstand large lateral earth pressure and water pressure. They are easy to construct, require no maintenance, and can be used as temporary or permanent retaining and water-stopping structures for underground structures.

[0003] Existing concrete sheet piles require two sets of sheet piles to be spliced ​​together during use. Due to structural limitations, they lack a dedicated water-stopping structure or only have a simple one. As the reinforced concrete sheet piles are driven into the ground, gaps inevitably appear at the connection between the two sets, affecting the water-stopping effect and reducing the overall performance of the sheet piles. To address the shortcomings of existing technology, we propose a reinforced concrete sheet pile with a water-stopping structure to solve the above problems. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This utility model discloses a reinforced concrete sheet pile with a water-stopping structure.

[0022] According to the appendix Figure 1-5 As shown, it includes a plate-shaped main body, which is composed of a first sheet pile 1 and a second sheet pile 2. The two ends of the first sheet pile 1 and the second sheet pile 2 are respectively fixed to form a first flange 101 and a second flange 102. A water-stopping unit 3 is provided at the connection between the first flange 101 and the second flange 102. The water-stopping unit 3 is composed of a first water-stopping component 301 and a second water-stopping component 302. The first water-stopping component 301 seals the connection between the first flange 101 and the second flange 102, and the second water-stopping component 302 absorbs leaked water. In use, the first sheet pile 1 and the second sheet pile 2 are first connected. (The last sentence appears to be incomplete and possibly refers to a different application of the technology.) In the foundation construction of structures such as sluice gates and pumping stations, concrete sheet piles can form a water-stop curtain. In estuary flood control walls, breakwaters, and other river and seawall management projects, they can effectively prevent river water or seawater from seeping into the foundation of the structure, prevent the foundation from being eroded by water, and improve the stability and durability of the structure. At the same time, during use, the water-stop unit 3 can seal the connection between the first sheet pile 1 and the second sheet pile 2, thereby preventing water from leaking out through the connection between the two sets of sheet piles. The water-stop unit 3 can form a continuous waterproof barrier at the connection of the sheet piles, directly preventing water from seeping from one side to the other through these gaps.

[0023] The end face of the second flange 102 at the first sheet pile 1 is in contact with the end face of the first flange 101 at the second sheet pile 2. The first water-stopping component 301 includes a first sealing plate 3011, a second sealing plate 3012, and a vent 3013. During use, the first sealing plate 3011 is located at the front end of the connection between the first flange 101 and the second flange 102, and the first sealing plate 3011 is in direct contact with water. For details, please refer to the appendix. Figure 4 First, the connection between the two sets of sheet piles is directly sealed and blocked by the first sealing plate 3011. Then, the first water-stopping component 301 can perform the first layer of water-stopping operation. Subsequently, a small amount of water will seep into the space between the inner wall of the first sealing plate 3011 and the outer wall of the first sheet pile 1 through the connection between the end face of the first sealing plate 3011 and the end face of the first sheet pile 1. Finally, it enters the installation groove 3022 through the connection between the two sets of sheet piles. The water-stopping expansion strip 3021 inside the installation groove 3022 can absorb the seeping water directly. Then, the second water-stopping component 302 can perform the second layer of water-stopping operation, providing multiple lines of defense and enhancing the reliability of water-stopping.

[0024] The first sealing plate 3011 is fixedly installed on one side of the outer wall of the first flange 101, and the inner wall of the first sealing plate 3011 is attached to one side of the outer wall of the second flange 102. The second sealing plate 3012 is fixedly installed on the other side of the outer wall of the second flange 102, and the inner wall of the second sealing plate 3012 is attached to the other side of the outer wall of the first flange 101. When the water-stop expansion strip 3021 absorbs too much moisture and expands prematurely, it may not be able to play its best water-stopping role in actual use. By opening a vent 3013 on the surface of the second sealing plate 3012 and the first flange 101, outside air can enter the interior of the mounting groove 3022 through the vent 3013. The air circulation at the vent 3013 is relatively good, which can keep the surrounding air relatively dry, thereby improving the drying effect of the water-stop expansion strip 3021, restoring the adsorption effect of the water-stop expansion strip 3021, and ensuring the use effect of the water-stop expansion strip 3021.

[0025] Ventilation openings 3013 are equidistantly provided at the second sealing plate 3012 and the first flange 101. By setting ventilation openings 3013, the water-stop expansion strip 3021 is placed at the ventilation openings 3013. The well-ventilated environment can reduce the humidity on the surface of the water-stop expansion strip 3021, making it difficult for microorganisms to grow and reproduce on its surface. The growth of microorganisms may damage the material of the water-stop expansion strip 3021, affecting its physical properties and water-stopping function. The air flow through the ventilation openings 3013 can reduce the humid environment required for microbial growth and extend the service life of the water-stop expansion strip 3021.

[0026] The second water-stopping component 302 includes a water-stopping expansion strip 3021, a mounting groove 3022, a mounting gasket 3023, and fixing bolts 3024. The mounting groove 3022 is formed inside the first flange 101 and the second flange 102. It should be noted that after the water-stopping expansion strip 3021 is fixedly installed inside the mounting groove 3022 by multiple sets of fixing bolts 3024, a certain amount of space is still reserved inside the mounting groove 3022 so that there will still be space inside the mounting groove 3022 after the water-stopping expansion strip 3021 expands when it comes into contact with water. The expansion strip 3021 accommodates the volume of the expanded water-stop strip 3021. The expansion strip 3021 is installed inside the mounting groove 3022, and the mounting gasket 3023 is installed on the outer wall of the expansion strip 3021. One end of the fixing bolt 3024 passes through the mounting gasket 3023 and is threaded into the expansion strip 3021 and the first flange 101. When the concrete sheet piles are transferred for use, multiple sets of sheet piles are first separated. However, prolonged use can easily reduce the adsorption effect of the expansion strip 3021, requiring... The water-stop expansion strip 3021 should be disassembled and replaced promptly. First, remove the multiple sets of fixing bolts 3024 from the inside of the water-stop expansion strip 3021 and the first flange 101. Then, tear the water-stop expansion strip 3021 from the inside of the mounting groove 3022. Finally, take the new water-stop expansion strip 3021, clean the inner walls of the two flanges, apply strong adhesive, and align and adhere the replaced water-stop expansion strip 3021 to the mounting groove 3022. This allows for quick replacement of the water-stop expansion strip 3021. The detachable and replaceable design allows for timely replacement of the water-stop expansion strip 3021 when aging is detected, ensuring that the water-stop component always maintains good performance, effectively preventing water leakage, ensuring the water-stopping quality of the concrete sheet pile, improving the utilization rate of the water-stop expansion strip 3021, and allowing maintenance personnel to perform more targeted maintenance on the water-stop component. Replacement can be selective based on the actual usage of the water-stop expansion strip 3021 in different parts.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
