Description
Technical field
Boat structure wave protection works technical field is the utility model is related to, in particular to for the anti-of bridge pier cofferdam
Wave apparatus.
Background technology
With the fast continual development of national coastal area economy, in order to connect each estuary, across each straits, connection
Engineering is got in touch with many island etc., and the Oversea bridge built is more and more.In the construction of deep-water bridge, what is built first is cofferdam
Structure, secondly the water body in cofferdam structure is removed, bridge pier structure is then built in anhydrous condition.And repairing in Oversea bridge
During building, maximum to hazard of bridge is not wind-force and rainwater, but the wave to come head-on.Particularly in bridge lower junction
During structure cofferdam construction, because lower part pile foundation and not completing, the huge load that wave is brought can not be born, if without anti-
Shield, then can seriously affect the construction of bridge structure, even result in collapsing for structure, therefore the protection of wave becomes Oversea bridge
A major issue urgently to be resolved hurrily in design and work progress.
Breakwater is a kind of common seashore, ocean engineering building, for blocking the transmission of Wave energy, while is also tieed up
The waters for having held structure rear defence region is steady.Traditional fixed breakwater, is mostly coastal waters breakwater, sea is fixed on basis
Bottom, high to foundation requirement, with the increase of the depth of water, cost can also increase, and not be suitable for deep water sea area.
In bridge pier process of construction, wave stroke that cofferdam is come head-on, according to the research experiment table of Wave Theory
Bright, the energy of wave concentrates on water surface top layer.Under Wave Load, cofferdam structure there are some potential safety problems, once
Cofferdam structure is destroyed, and Bridge Pier Construction falls short of success for lack of final effort before being not only allowed to, and causes very big economic loss, can also be produced certain
Casualties.And existing breakwater structure does not obtain good application during cofferdam construction, therefore, this practicality is new
Type is intended to optimize for breakwater common at present, proposes a kind of available for reasonable during sea-spanning bridge con struction
Structure design, makes this kind of breakwater have more preferable mobility, detachability and anti-ripple performance, completion is built easy to deep-water pier
Movement afterwards makes it have more rational cost with arranging again, can largely apply among the design and construction of Oversea bridge.
