Description
Technical field
The present invention relates to a kind of breakwater.Specifically a kind of floating breakwater.
Background technology
Breakwater is a kind of common coastal structures, mainly for the protection of in coastal structures and harbour
Boats and ships.Fixing bottom tradition breakwater, along with ocean development gradually extends to deep-sea, tradition breakwater is built
It is set as the problems such as high, a construction difficulty to become increasingly conspicuous.Therefore, floating breakwater becomes port cooperation
One of key technology.
Floating breakwater (Floating Breakwater is called for short FB) is important as a class in ocean engineering
Breakwater structure, the wave absorption buoyancy aid generally manufactured by metal, armored concrete and plastic or other material and anchoring system
The breakwater of system composition.Wave absorption buoyancy aid is formed by by casing or the floating mat of certain draft.Casing is with floating
Row is fixed on the anchor chain in seabed and is connected and swims on the water surface with one end.Floating breakwater utilizes one to be incorporated into the depth of water
Wave energy is reflected, dissipates and crushes to reach wave absorption, wave resistance purpose by the wave absorption buoyancy aid of degree.Major advantage:
1) low cost is built, and is not affected by seabottom geology condition and the depth of water；2) convenient transportation, builds rapidly,
Remove easily, especially to interim breakwater；3) cost is less by water depth effect；4) below structure
Water circulation, biological exchange, silt flowing can be carried out, there is ecological dominance.
Fibre reinforced composites (fiber reinforced polymer/plastic, be called for short FRP) be by
The high-performance novel material that fibrous material mixes by a certain percentage with matrix material and formed through certain process combining
Material.FRP is high-strength with it, lightweight, the advantage such as corrosion-resistant start to be applied in building with building engineering structure.
American-European experience have shown that, the buoyancy tank breakwater with plastics buoyancy tank as component is due to the intensity of material and aging
Etc. problem, easily destroyed, should pay the utmost attention to use concrete floating box structure.In China, timber, steel
The inadequate resource such as material, waste tire of automobile, concrete becomes the construction material that China is main.
But, the floating breakwater structure either made with armored concrete or steel, hot and humid
Working in the marine environment of high salt, steel significant corrosion problems is the most prominent, and difficult in maintenance, and then reduces
Service life of floating breakwater.And the case net type floating breakwater being made with FRP material, use
FRP muscle and FRP grid material, in marine environment, corrosion resistance is strong, is not required to long term maintenance, light weight, intensity
Height, convenient transport, with prefabricated, can realize Fast Installation and recovery.
" board-net structure floating breakwater disappear wave performance experimental study " (" engineering mechanics " in July, 2006)
In one literary composition, it is proposed that a kind of plate-net formula floating embankment structure, result of the test shows that dike width offsets wave performance and has notable shadow
Ringing, the biggest wave absorbing effect of dike width is the best.The wave performance that disappears of floating embankment can be improved plus etting in flat board bottom, increases
The rigidity of strong flat board can significantly improve the wave absorbing effect of floating embankment.
In the Master's thesis of " floating breakwater of a kind of wire mesh cage structures ", describe the floating of a kind of wire mesh cage structures
Formula breakwater, can either reduce and clash into by the risk of shielding structure after breakage occurs in breakwater, can keep away simultaneously
Exempt to occur that similar common floating box type breakwater or float-type breakwater are when external structure occurs seeping water in crack
Lose the dangerous situation of performance capacity.
Summary of the invention
It is an object of the invention to provide a kind of favorable anti-corrosion effect and have reflection concurrently, dissipate and crush wave absorption function
Case net type floating breakwater based on FRP material.
The object of the present invention is achieved like this: includes buoyancy tank, the grid being connected under buoyancy tank and anchor chain
With anchor ingot, described buoyancy tank by indulging Rectangular Concrete buoyancy tank beam, transverse and longitudinal Rectangular Concrete buoyancy tank beam is constituted, vertical
Horizontal Rectangular Concrete buoyancy tank beam is by concrete prefabricated integral, and Rectangular Concrete buoyancy tank beam is in " well " word in length and breadth
Beam structure is distributed, and is respectively provided with FRP in the lower section of vertical Rectangular Concrete buoyancy tank beam and horizontal Rectangular Concrete buoyancy tank beam
Grid, each FRP grid connects and composes grid screen basket structure.
The present invention can also include:
1, vertical Rectangular Concrete buoyancy tank beam and horizontal Rectangular Concrete buoyancy tank beam are laid with FRP muscle.
2, FRP grid is cast into one with Rectangular Concrete buoyancy tank beam in length and breadth.
3, in described wire mesh cage structures, each FRP grid is intertwined and connected by FRP cloth and resin glue.
The present invention solves that technical problem present in existing floating breakwater technology provides a kind of structure letter
Single, intensity high, can save engineering material and has having reflection concurrently, dissipating and crush wave absorption of antiseptic effect
The case net type floating breakwater based on FRP material of function.
The technical scheme is that a kind of to have reflection concurrently, dissipate and crush the case net type floating of wave absorption function and prevent
Ripple dike, is formed buoyancy tank by multiple FRP muscle-concrete buoyancy tank beam, and buoyancy tank is fixed on the bottom by anchor chain and anchor ingot,
Described buoyancy tank has the wire mesh cage structures being made up of FRP grid material and forms damping structure, and described buoyancy tank includes many
Individual Rectangular Concrete buoyancy tank beam, by the prefabricated connection of rectangular box beams of concrete, described buoyancy tank top view is in " well "
Tee beam structure, be cast in bottom FRP grid material together with.
Described floating breakwater uses top view in the buoyancy tank being similar to " well " tee beam plate structure, it is possible to increase
Add wave energy reflection, each beam type buoyancy tank wave energy can be produced by the cavity that the cavity formed and each grid material are formed
Raw certain dissipation effect, meanwhile, the wire mesh cage structures that buoyancy tank bottom is made up of grid material is in beam type buoyancy tank bottom
Form damping structure and wave is produced fragmentation, the ripple of different direction of vibration can be eliminated, make wave absorbing effect
It is improved significantly.
Described floating breakwater buoyancy tank uses that FRP reinforced concrete is prefabricated forms, and bottom damping structure uses FRP
Grid material composition wire mesh cage structures, together with described buoyancy tank is cast in grid material, grid cell by FRP cloth and
