Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy construction, and in particular relates to a water-stopping structure for adjacent gaps of an aqueduct. Background Art

[0002] In water conservancy projects, aqueduct is also called water bridge, which is connected to the channel at both ends. U-shaped aqueduct is an overhead trough that transports channel water across rivers, valleys, depressions and roads. It is commonly used for irrigation, water delivery and flood drainage, and is mainly built with materials such as stone masonry, concrete and reinforced concrete.

[0003] After searching, Chinese patent announcement number: CN217974240U discloses an aqueduct structure and its waterstop structure. In the utility model, a layer of waterstop is attached to the outer wall of the U-shaped aqueduct joint to reduce the leakage at the U-shaped aqueduct joint. However, during the long-term use of the U-shaped aqueduct, the waterstop at the joint will age and break or fall off, so that the U-shaped aqueduct joint is damaged, resulting in leakage. A placement groove is provided on the waterstop so that the waterstop can be attached from the inside out, and the support part, triangular part and clamping part on the arc-shaped clamping strip are used to support the waterstop for the first time. Since the waterstop of this device is immersed in a liquid environment for a long time, it is easy to be eroded and corroded by the liquid. For this reason, it is urgent to design a waterstop structure for adjacent gaps of an aqueduct to solve the above problems. Summary of the invention
