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

The invention discloses an anti-wave impact device for bridge piers, which belongs to the technical field of bridge construction. The vertical wave-scattering component of the device is arranged in a ring on the periphery of the bridge pier and embedded in the bearing layer of the seabed foundation, and is connected and fixed with the ring-direction wave-scattering component to form a ring. The frame structure can withstand the impact load of waves in all directions. By staggering and setting three layers of vertical wave-sparing tubes and two-layers of circular wave-sparing tubes, they are connected and fixed to form a multi-layer network structure, which is used to generate vibration and reflection, breaking and friction of waves under the action of wave impact load , and make the wave form a vortex to consume the wave impact energy. The wave impact energy is guided and released through the vertical wave-absorbing chamber arranged on the vertical wave-sparing assembly and the annular wave-absorbing chamber on the circumferential wave-sparing assembly. The device of the invention can consume a large amount of wave impact energy, and provide comprehensive protection against wave impact for bridge piers. The whole device has the advantages of simple structure, convenient construction, low cost and good effect of preventing wave impact.
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 ...
