Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a water-stopping device for a bridge expansion assembly. Background Art

[0002] A bridge expansion device is a device installed between two beam ends, between a beam end and an abutment, or at a hinged joint of a bridge to meet the requirements of bridge deck deformation. The device is required to be able to freely expand and contract in both directions parallel and perpendicular to the bridge axis, be firm and reliable, and run smoothly without sudden jumps or noise when vehicles pass through it. A water-stop device for a bridge expansion device can prevent rainwater or quicksand from entering the device, causing it to become blocked and lose its original function. To this end, we provide a water-stop device for bridge expansion assemblies.

[0003] In the prior art, a Chinese patent document with the publication number CN216141889U and the publication date of March 29, 2022 was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A water-stop device for a bridge telescopic assembly, comprising a bridge body and a water-stop strip, a water-stop strip being installed in the middle of the bridge body, a clamping device being threadedly connected to the upper surface of the bridge body, an installation groove being provided at the bottom of the clamping device, a fixed block being installed inside the installation groove, a protective gasket being fixedly installed on the inner top wall and the inner bottom wall of the fixed block, and a first spring block being fixedly installed on the inner side wall of the fixed block.

[0004] In order to solve the problem of waterstopping for the telescopic assembly of the bridge, the existing technology is to absorb the kinetic energy generated when the bridge is deformed by setting multiple springs, thereby reducing the telescopic change and directly applying excessive tensile stress to the waterstop, causing the waterstop to break and lose its original function, thereby extending the service life of the waterstop. Through the setting of the water pipe, the accumulated water overflowing into the waterstop can be discharged from both ends of the water pipe in time. However, the waterstop assembly is set below the telescopic assembly, and its effect is poor. The telescopic assembly will be affected by external impurities, causing the expansion gap to be blocked, thereby reducing work efficiency. Utility Model Content
