Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a joint water-stop device for aqueducts indirectly. Background Art

[0002] An aqueduct, also known as an elevated canal or water conveyance bridge, is a water conveyance system composed of a group of bridges, tunnels or ditches. An aqueduct refers to an overhead water trough that conveys the water flow in a channel across rivers, valleys, depressions and roads, and is commonly used for irrigation water conveyance, and also for flood discharge, sediment discharge, etc. Large aqueducts can also be navigable. Aqueducts are mainly made of materials such as masonry, concrete and reinforced concrete. The existing water-stop methods need to be built in cooperation with the support and lifting structures of the aqueduct.

[0003] After retrieval, Chinese Patent Publication No. CN219059960U discloses a joint water-stop device for aqueducts indirectly, which relates to the technical field of indirect joint water-stop. It includes an aqueduct, the bottom end of the aqueduct is fixedly connected with a trough pier, one outer wall of the aqueduct is slidably connected with a pressing plate, the top end of the pressing plate is fixedly connected with a first baffle, both ends of the pressing plate are respectively fixedly connected with a second baffle, and an elastic convex block is arranged at one end of the second baffle. By setting the first baffle and the second baffle, the utility model can completely block the glue connection part of the aqueduct, avoid the glue leaking out, and the glue bonding becoming loose due to the long-term impact and soaking of water, resulting in water leakage. At the same time, through the connection of the elastic convex block with the aqueduct, a double-layer support for the aqueduct can be formed, making the connection part of the aqueduct more stable. At the same time, when the pressing plate, the first baffle, the second baffle and the elastic convex block are not damaged, they can be disassembled and used continuously, saving resources.

[0004] However, in the above technical solution, only the arc-shaped first baffle is attached above the joint of the aqueduct to block the water body to prevent it from affecting the glue. However, due to the influence of thermal expansion and contraction of the concrete material in the external environment, the adjacent aqueducts expand and contract through the joint between them. The pressing plate in the joint is easily squeezed and deformed and damaged, which in turn causes the first baffle to loosen and displace, and cannot be closely attached to the aqueduct, resulting in water leakage.
