Description

Technical Field

[0001] This utility model relates to the field of water-stopping mechanism technology, and in particular to a water-stopping structure for aqueducts. Background Technology

[0002] Aqueducts, as important hydraulic engineering facilities, play a crucial role in water conservancy construction. They not only cross various natural obstacles, such as rivers, canyons, and roads, but also ensure the smooth and unobstructed transport of water to designated locations. Aqueducts have diverse structures and can be classified into open-channel aqueducts, covered-channel aqueducts, culvert aqueducts, and bridge aqueducts, according to their uses and structural forms.

[0003] During the design and construction of aqueducts, expansion joints are typically installed between adjacent sections. These joints are designed to accommodate the deformation of the aqueduct under varying temperature, humidity, and load conditions, preventing structural damage due to excessive deformation. However, the presence of expansion joints also presents challenges for waterproofing the aqueduct. To ensure that the aqueduct does not leak during normal use, effective waterproofing mechanisms must be installed within the expansion joints.

[0004] Traditional water-stopping mechanisms typically employ a single-layer waterstop strip. While this structure is relatively simple, its water-stopping effect is often poor. Therefore, this application proposes a water-stopping structure for aqueducts to address the aforementioned problems. Utility Model Content
