Wave impact prevention device for bridge pier

Abstract

The invention discloses a wave impact prevention device for a bridge pier, and belongs to the technical field of bridge constructions. According to the device, a vertical wave dredging assembly is annularly arranged on the periphery of the pier, embedded in a seabed foundation bearing stratum and fixedly connected with an annular wave dredging assembly to form an annular frame structure, and the impact load of waves can be withstood in all directions. The three layers of vertical wave dredging pipes and the two layers of annular wave dredging pipes are arranged in a staggered mode and are mutually connected and fixed to form a multi-layer net-shaped structure, and wave impact energy is consumed in the mode that the structure generates vibration and reflects, breaks and rubs waves under the action of wave impact loads, the waves form vortexes and the like. Wave impact energy is guided and released through a vertical wave dissipating cavity formed in the vertical wave dredging assembly and an annular wave dissipating cavity formed in the annular wave dredging assembly. The device can consume a large amount of wave impact energy and comprehensively provide wave impact prevention protection for the pier. The whole device is simple in structure, convenient to construct, low in cost and good in wave impact prevention effect.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an anti-wave impact device for bridge piers. Background technique [0002] With the economic development of our country, more and more cross-sea bridges have been built or are under construction, and the scale is getting bigger and bigger. The small and medium-sized waves caused by the daily ebb and flow of the sea impact the pier of the bridge across the sea, which will cause the pier to swing and affect the driving comfort. In severe cases, it will affect the normal use of the bridge. In addition, my country's coast is also a typhoon-prone area. The large and extra-large waves caused by typhoons impact on the bridge piers across the sea, which will cause relative slippage between the bridge piers and the main girder, affecting the normal use of the bridge and even endangering the structural safety. [0003] At present, there is no device specially used ...

AI Technical Summary

Problems solved by technology

The small and medium-sized waves caused by the daily ebb and flow of the sea impact the pier of the cross-sea bridge, which will cause the pier to swing and affect the driving comfort. In severe cases, it will affect the normal use of the bridge.

In addition, my country's coast is also a typhoon-prone area. The large and extra-large waves caused by the typhoon impact the bridge piers across the sea, which will cause relative slippage between the bridge piers and the main girder, affecting the normal use of the bridge and even endangering the structural safety.

[0003] At present, there is no special device for pier anti-wave impact, so the anti-wave impact of bridge pier is an urgent technical problem to be solved by those skilled in the art
