Abstract

The present invention relates to a breakwater, particularly to a permeable breakwater which comprises a foundation, upright posts and at least two rows of wave screening boards, wherein the upright posts are connected with the rigid structure of the foundation; the wave screening boards are distributed along the thickness direction of the breakwater in a cascade mode; the wave screening boards are connected between the upright posts in a bridge mode, gaps 21 are distributed at intervals on the wave screening boards, and an energy dissipating structure which changes the water particle motion tracks is arranged on each of the wave screening boards. Because a mode that wave screening and energy dissipating are simultaneously used, the increase of the structural load is relatively far less under the condition that compared with the prior art, the wave dissipating coefficient of the present invention is increased by 17 to 37 percentage points, and the average value is increased by about 100%.

Description

Curtain wall type breakwater

The present invention relates to a kind of mole, particularly a kind of curtain wall type breakwater.

Curtain wall type breakwater is light and handy with structure, and cost is low to be good at, but its contradiction that disappears between unrestrained effect and the structural loads can't obtain desirable the solution always.Dwindle the section air permeability rate, to keep off wave, then the wave height reflection is big before the dike, structure stress is big; Otherwise the structure air permeability rate is big, and unrestrained weak effect disappears.Owing to have the thinking mistaken ideas of manger board with simple retaining wave are set,, are interspersed with pile foundation forward and backward merely and dwindle between stake the slit to keep off wave, so keep off unrestrained weak effect so the row's manger board of arranging on pile foundation that has in the prior art is not even established manger board.

The objective of the invention is to overcome weak point of the prior art, and provide a kind of wave that disappears effective, structure reflection simultaneously and the unrestrained curtain wall type breakwater that combines with energy dissipating of stressed less again retaining.

The objective of the invention is to realize by following approach.

Curtain wall type breakwater, comprise basis, the column that is connected with basic rigid-framed structure and be bridged on manger board on the column, be distributed with the space on the manger board, its structural feature is: at least two rows are along being furnished with the energy-dissipating structure that changes the water particle movement locus on the manger board of mole thickness direction echelon distribution.

The load that manger board applied respectively that wave distributes to echelon is also inequality at one time sometimes.Utilize the phase difference of this wave, increase manger board quantity and the increase of the given tensile load that causes superposes much smaller than arithmetic, and the increase of manger board row number, strengthened the retaining wave scope of structure, reduced air permeability rate, thereby improved the unrestrained effect that disappears structure function.And the utilization of the generation of energy dissipating effect and phase difference all makes increase that manger board quantity increases more and breakwater structure load seldom.

Said energy-dissipating structure can comprise: forward and backward being interspersed in space on adjacent two row's manger boards.

Keep off by row under the situation of wave at many row's manger boards, the forward and backward staggered coverage of member is repeatedly disturbed, and repeatedly changes the fluctuation water particle direction of motion, makes it collision mutually or produces the eddy current friction, consume wave energy step by step, and the wave height reflection is less before the dike; The fluctuation water particle can take place repeatedly to reflect, particularly repeatedly reflection between two manger boards, and causing forward and backward of manger board all to act on has the seaway load that direction is opposite, can reduce mutually, and this energy dissipating decompression mechanism makes the stressed minimizing of manger board.

Above-mentioned energy-dissipating structure also can comprise:

To be the place ahead before the dike, the void content on the row's manger board of back is smaller than front-seat manger board;

Being that space on the place ahead, the front-seat manger board is greater than the space on back row's manger board before the dike.

Void content is a manger board cross section void area and the ratio of manger board cross sectional area.The consideration of dredging the close energy-dissipating structure design in back before these two kinds of spaces is: front-seat manger board is stressed bigger, increase the load of air permeability rate to reduce structure is produced, it is stressed relatively less then to arrange manger board, reduces air permeability rate, not only improves the unrestrained effect of retaining, also reduce and balanced structure stress, because front-seat manger board air permeability rate is big, the preceding wave height stack of dike is little simultaneously, and wave height is also less relatively behind the dike, like this, disappear unrestrained effect again to improve; The forward and backward row of air permeability rate is different, thereby the motion height that not only improves fluctuation water particle vertical direction increases gravity acting with energy dissipating, and has aggravated the disorder of the water particle direction of motion again, therefore also is able to energy dissipating.

At least be furnished with three layers of space between on the manger board short transverse.

The close layout in forward and backward staggered and preceding thin back, space on adjacent two row's manger boards can be convenient to carry out in space more than three layers or three layers.

In sum, the present invention has following advantage compared to existing technology: the retaining wave develops simultaneously with energy dissipating.The fluctuation water particle repeatedly change the direction of motion, repeatedly disturbed, repeatedly the reflection and degree violent, the unrestrained effect that disappears is obvious, experimental data shows, its wave transmissivity is (wave 46%～72% promptly disappears) between 0.28～0.54, the unrestrained coefficient ratio prior art that disappears has improved 17～37 percentage points, about average doubles, but the structural loads increase is much less relatively, and wave height reflection is less before the dike, thereby has found one to solve structural safety, control budget and the better approach of the contradiction between the unrestrained effect three of disappearing.
