Description

Technical Field

[0001] The utility model belongs to the technical field of anti-seepage devices, and particularly relates to a water-stop sleeve used for waterproofing industrial pools. Background Art

[0002] With environmental protection currently being prioritized nationwide and globally, leak prevention in highly polluting industrial pools has become particularly crucial. In the construction of specialized industrial pools, such as oxidation tanks, waterstop sleeves are often used to prevent leakage at the joints between the pool body and the pipes. Fiberglass reinforced plastic (FRP) is widely used in waterstop sleeves due to its excellent corrosion resistance. However, FRP is slightly hydrophobic, so FRP waterstop sleeves and concrete don't fit perfectly together. Minor cracks can develop at the interface, leading to water seepage and leakage. Furthermore, gaps can easily form between the pipes to be installed and the waterstop sleeves, and poor sealing of these gaps can also lead to water seepage. Utility Model Content

[0003] In order to solve the above technical problems, the present application provides a water-stop sleeve for waterproofing industrial water pools, comprising a sleeve body and at least one water-stop ring sleeved along the outer wall of the sleeve body, the water-stop ring comprising a horizontal portion connected to the sleeve body and an upwardly bent portion connected to the horizontal portion, the horizontal portion, the bent portion and the outer wall of the sleeve body forming a space for accommodating liquid, and when the liquid in the pool leaks, it will first be stored in the space, extending the water seepage path, thereby improving the water-stopping effect. The sleeve body is sleeved on the outside of the pipe to be installed, and the water-stop sleeve also includes a seal for closing the gap between the pipe to be installed and the sleeve body. Sealing the water-stop sleeve and the pipe to be installed can further improve the waterproofing ability.

[0004] In some embodiments, the sealing member is a sealing ring disposed between the inner wall of the sleeve body and the outer wall of the pipe to be installed, and the inner wall of the sleeve body is provided with a sealing boss for supporting the sealing ring. The sealing ring cooperates with the sealing boss to prevent liquid in the pool from leaking through the gap between the sleeve body and the pipe to be installed.

[0005] In some embodiments, the seal can also be an end cap with a central hole. The inner diameter of the central hole can closely match and seal the outer diameter of the pipe to be installed, and the inner wall of the end cap can be interlocked with the outer wall of the sleeve body. Alternatively, the end cap can be threadedly connected to the inner wall of the sleeve body, with a sealing filler such as sealing tape or sealant disposed between the threads. The end cap can conveniently seal the gap between the pipe to be installed and the water-stop sleeve.

[0006] In some embodiments, the outer wall of the sleeve body and the inner wall of the waterstop ring may be movably connected. For example, the outer wall of the sleeve body and the inner wall of the waterstop ring may be threadedly connected, with a sealing filler disposed between the threads. Alternatively, the outer wall of the sleeve body and the inner wall of the waterstop ring may be interference-fitted, with the pressure generated by the interference fit sealingly connecting the waterstop ring to the sleeve body.

[0007] In some embodiments, the sleeve body and the water stop ring can also be integrally formed, which can not only improve the waterproof effect and reduce the difficulty of installation, but also effectively reduce production costs and improve production efficiency during mass production.

[0008] The angle between the bent portion and the horizontal portion of the water stop ring is not limited to a specific angle, as long as it is bent upward, and the two can also be arranged vertically.

[0009] As a further improvement, the water-stop sleeve may be made of corrosion-resistant materials, such as stainless steel, fiberglass, PVC plastic, etc., to adapt to different usage scenarios.

[0010] Beneficial effects of this application: The utility model provides a bending portion on the water stop ring, changes the structure of the water stop ring, extends the water seepage path, and improves the water stop effect. At the same time, a sealing member is provided between the sleeve body and the pipe to be installed to achieve a seal between the water stop sleeve and the pipe to be installed, further improving the waterproof capability.
