Description

Technical Field

[0001] The utility model belongs to the technical field of water-stopping devices, and in particular relates to a water-stopping structure for a structural seam of an aqueduct body. Background Art

[0002] In the construction of irrigation areas of farmland water conservancy projects, when the water delivery channel needs to cross low-lying terrain such as ditches and rivers, in order to reduce head loss and smoothly connect with the water flow upstream of the channel, a common crossing structure is called an aqueduct. The length of a single span of the aqueduct body is generally 10m-20m. When the aqueduct is used to cross the river valley, due to the long span length, the aqueduct generally adopts a multi-span design scheme, and expansion joints are formed between the adjacent spans of the body. In order to reduce water leakage at the expansion joint, a water stop device needs to be installed at the expansion joint. The most common water stop device is a rubber pressure plate type water stop device.

[0003] Chinese patent application No. 202311361458.5 discloses a water-stop device for expansion joints of aqueduct body, which relates to the technical field of water-stop devices, including: a trough body, which is provided with multiple trough bodies, and an expansion joint is formed between the end faces of adjacent trough bodies; an inner water stop, which is respectively connected to two adjacent trough bodies, and the inner water stop is blocked at the expansion joint near the inner wall of the trough body; an outer water stop block, which is provided with multiple outer water stop blocks, which are respectively detachably connected to two adjacent trough bodies, and the outer water stop block is blocked at the expansion joint near the outer wall of the trough body; an isolation block, which is provided with multiple isolation blocks, which are filled and blocked in the expansion joint, and the isolation block is located between the inner water stop and the outer water stop block. During the entire repair process, the replacement of the isolation block and the outer water stop block is carried out on the outside of the trough body, and the inner water stop is not processed, so there is no need to drain the water in the aqueduct, and it will not affect the normal water supply of the aqueduct.

[0004] In the above-mentioned public patent, the two ends of the connecting plate are respectively sleeved on the studs at the connecting ends of the two groove bodies for connection and fixation.

The water stop limit is performed by controlling the pushing block to move downward to squeeze the water stop belt to seal the connecting groove. The pushing block is small in size and cannot fully press the water stop block, and the sealing effect is general. Utility Model Content
