Description

Technical Field

[0001] The utility model relates to the technical field of waterstop strips, in particular to a novel waterstop strip for railway tunnels. Background Art

[0002] Waterstop for railway tunnel plays a vital role in railway tunnel engineering. It can effectively prevent groundwater from penetrating into the tunnel, protect the railway tunnel structure from water damage, and ensure the safety and sustainability of railway transportation. The use of waterstop can effectively extend the service life of the tunnel, reduce maintenance costs, and improve the reliability and efficiency of the railway transportation system.

[0003] After searching, Chinese patent announcement number: CN212642761U discloses a new type of waterstop for railway tunnels, including a first waterstop and a second waterstop, one side of the first waterstop and the second waterstop is fixedly connected with a sealing card belt, the other side of the first waterstop and the second waterstop is provided with a sealing card groove used in conjunction with the sealing card belt, the sealing card belt is detachably connected to the sealing card groove, and the outer side of the first waterstop is close to one end of the second waterstop and is fixed with a clamp. The utility model has a simple structure. By arranging a sealing card belt between the first waterstop and the second waterstop, the first waterstop and the second waterstop are conveniently and quickly connected, and the clamp is used to fix them, so as to facilitate the connection and addition of the waterstop; by arranging a fastening mechanism, the two ends of the entire waterstop are stretched, so that the waterstop is in a taut state, which prevents the waterstop from being in a loose state after installation, thereby improving the waterproof effect of the waterstop.

[0004] The above technology stretches the two ends of the entire waterstop to keep the waterstop in a taut state, preventing the waterstop from being in a loose state after installation, thereby improving the waterproof effect of the waterstop. However, when the waterstop is used for a long time, the wall will continuously stretch the waterstop due to thermal expansion and contraction. The insufficient tensile strength of the waterstop may cause the waterstop to break and thus fail to provide waterproofing. Therefore, a new type of waterstop for railway tunnels is proposed to solve the above problem. Utility Model Content

[0007] Furthermore, the wear-resistant component includes a polytetrafluoroethylene coating, and the polytetrafluoroethylene coating is fixedly connected to the outer periphery of the waterstop.

[0008] Furthermore, a drainage hole is provided in the middle of the water stop belt.
