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 the ship in coastal structures and harbour
Oceangoing ship.Traditional breakwater bottom is fixed, and as ocean development gradually extends to deep-sea, traditional breakwater construction cost is high, it is tired to build
The problems such as difficult, becomes increasingly conspicuous.Therefore, floating breakwater becomes one of key technology of port cooperation.
Floating breakwater (Floating Breakwater, abbreviation FB) is as a kind of important breakwater in ocean engineering
Structure, the breakwater being usually made of the wave absorption floating body and mooring system of the manufacture of metal, armored concrete and plastic or other material.Disappear
Ripple floating body the babinet or floating mat of certain draft by being made of.The anchor chain that babinet and floating mat are fixed on seabed with one end is connected
And it swims on the water surface.Floating breakwater reflects wave energy, dissipated and is crushed using the wave absorption floating body of certain underwater penetration
To reach wave absorption, wave resistance purpose.Major advantage：1) low cost is built, from the influence of seabottom geology condition and the depth of water；2) transport
It is convenient, it builds rapidly, it is easy to remove, especially to interim breakwater；3) cost is smaller by water depth effect；It 4) can under structure
Cycling of water, biology exchange, silt flowing are enough carried out, there is ecological dominance.
Fibre reinforced composites (fiber reinforced polymer/plastic, abbreviation FRP) are by undulation degree
Material with basis material is mixed in a certain ratio and passes through the high-performance novel material that certain process combining is formed.FRP with its is high-strength,
Lightweight, it is corrosion-resistant the advantages that start to be applied in building and building engineering structure.
It is American-European experience have shown that, asked using plastics buoyancy tank as the buoyancy tank breakwater of component due to the intensity of material and aging etc.
Topic, is easily destroyed, should pay the utmost attention to use concrete floating box structure.In China, timber, steel, waste tire of automobile etc.
Inadequate resource, concrete become the main construction material in China.
However, the floating breakwater structure either made with armored concrete or steel, hot and humid with high salt
It works in marine environment, steel significant corrosion problems are very prominent, and difficult in maintenance, thereby reduce the use of floating breakwater
Service life.And the case net type floating breakwater being made with FRP material, using FRP tendons and FRP grid materials, in marine environment
Corrosion resistance is strong, is not required to long term maintenance, light weight, and intensity is high, convenience in transport and prefabricated, can realize Fast Installation and recycling.
The experimental study of unrestrained performance " board-net structure floating breakwater disappear " (《Engineering mechanics》In July, 2006) in a text, carry
A kind of plate-net formula floating embankment structure is gone out, result of the test shows that dike is wide and offsets unrestrained performance and have a significant impact, the wide bigger wave absorbing effect of dike
Better.Tablet lower part can improve the unrestrained performance that disappears of floating embankment plus etting, and floating embankment can be significantly improved by enhancing the rigidity of tablet
Wave absorbing effect.
In the Master's thesis of " a kind of floating breakwater of wire mesh cage structures ", a kind of anti-ripple of the floating of wire mesh cage structures is described
Dike, can either reduce breakwater occur it is damaged after hit by the risk of shielding structure, while can avoid the occurrence of similar common
Floating box type breakwater or float-type breakwater are when crack infiltration occurs in external structure and lose the dangerous situation of work capacity.
The content of the invention
It is an object of the invention to provide a kind of favorable anti-corrosion effect and have both reflection, dissipation and broken wave absorption function based on
The case net type floating breakwater of FRP material.
The object of the present invention is achieved like this：Including buoyancy tank, the grid being connected under buoyancy tank and anchor chain and anchor ingot,
The buoyancy tank is made of vertical Rectangular Concrete buoyancy tank beam, horizontal Rectangular Concrete buoyancy tank beam, in length and breadth Rectangular Concrete buoyancy tank beam by
Concrete prefabricated integral, Rectangular Concrete buoyancy tank beam is in " well " tee beam structure distribution in length and breadth, in vertical Rectangular Concrete buoyancy tank
FRP grids are respectively provided with below beam and horizontal Rectangular Concrete buoyancy tank beam, each FRP grids connect and compose grid wire mesh cage structures.
The present invention can also include：
1st, indulge in Rectangular Concrete buoyancy tank beam and horizontal Rectangular Concrete buoyancy tank beam and be laid with FRP tendons.
2nd, FRP grids and the casting of Rectangular Concrete buoyancy tank beam in length and breadth are integral.
3rd, each FRP grids are intertwined and connected by FRP cloth and resin glue in the wire mesh cage structures.
The present invention provides a kind of simple in structure, intensity to solve technical problem present in existing floating breakwater technology
It is high, can save engineering material and have the function of anti-corrosion effect have both reflection, dissipation and broken wave absorption based on FRP material
Case net type floating breakwater.
The technical scheme is that a kind of case net type floating breakwater for having both reflection, dissipation and broken wave absorption function,
Buoyancy tank is formed by multiple FRP tendons-concrete buoyancy tank beam, buoyancy tank is fixed on the bottom by anchor chain and anchor ingot, and the buoyancy tank has
The wire mesh cage structures being made of FRP grid materials form damping structure, and the buoyancy tank includes multiple Rectangular Concrete buoyancy tank beams, passes through square
The prefabricated connection of shape box beams of concrete, the buoyancy tank top view are in " well " font girder construction, and one is cast in lower part FRP grid materials
It rises.
It is anti-can to increase wave energy using the buoyancy tank that top view is in similar to " well " font contignation for the floating breakwater
It penetrates, the cavity that the cavity and each grid material formed by each beam type buoyancy tank is formed can generate wave energy certain dissipation effect,
Meanwhile buoyancy tank lower part is formed damping structure in beam type buoyancy tank lower part by the wire mesh cage structures that grid material forms and broken make is generated to wave
With can eliminate the ripple of different direction of vibration, wave absorbing effect is made to be improved significantly.
The floating breakwater buoyancy tank is formed using FRP tendons are concrete prefabricated, and lower part damping structure uses FRP grid material groups
Into wire mesh cage structures, together with the buoyancy tank is poured with grid material, grid cell is connected by FRP cloth and resin glue winding, is enhanced
The globality and stability of the floating breakwater, while FRP is high-strength, lightweight, it is corrosion-resistant, add the floating breakwater
Service life.
The configuration of the present invention is simple, FRP material is corrosion-resistant and intensity is higher, can save engineering material；From heavy and light, reduction pair
The design requirement of anchoring system；The ripple of different direction of vibration can be eliminated using grid wire mesh cage structures, so as to play comprehensive disappear
Ripple effect；Meanwhile it is prefabricated using armored concrete, FRP with solve floating breakwater rough seas corrosion ask
Topic makes construction and safeguards more convenient.And the case net type floating breakwater being made with FRP material, using FRP tendons and
FRP grid materials, corrosion resistance is strong in marine environment, is not required to long term maintenance, and light weight, intensity is high, convenience in transport and prefabricated, energy
Realize Fast Installation and recycling.Suitable for the offshore waters that surrounding is open, wave action is little, wave direction is indefinite, can be supported for aquatic products
Grow, the places such as artificial beach and yacht wharf provide effectively shielding, have wide practical prospect.
