Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge engineering, in particular to a river channel bridge pier anti-scouring mechanism. Background Art
[0002] Scour of bridge piers is a key link in bridge design. Its damage to bridges is mostly sudden and accidental. There are many factors affecting pier scour, which are difficult to predict accurately. Changes in hydrological phenomena often cause sudden and accidental damage to bridge structures, especially in places where the flow velocity is large near the pier, downstream of reservoirs, dams, and power stations. The impact on piers is very large and difficult to predict. The depth and severity of scour of bridge piers directly threaten the safety of pier foundations. Scour itself is a complex and comprehensive process with many influencing factors. Scour damage to foundation structures is one of the main reasons for the failure of bridge structures and the loss of their safety performance. Therefore, bridge piers often require anti-scour mechanisms to protect them.
[0003] The existing anti-scour mechanism is often an integral whole. When some parts of the anti-scour mechanism need to be replaced, the entire anti-scour mechanism needs to be lifted out of the water and replaced. This operation is difficult, and the anti-scour mechanism needs to be replaced as a whole. This is not only costly but also cumbersome. Therefore, the present application proposes an anti-scour mechanism for river bridge piers to solve the above technical problems. Utility Model Content
