Abstract

The present invention discloses a permeable piled offshore breakwater which is made up by multi-piles, between piles the permeable gap is set. Said invention defines the permeability rate as: pile permeable gap width/(diameter of pile + pile permeable gap width), and the effective permeability rate is limited at 0.2-0.6. Said invention can effectively abate wave energy, change wave form and can protect sand source.

Description

Permeable pile type offshore dam
The present invention relates to a kind of permeable pile type offshore dam that is used for beach protection and siltation promotion.
At present, adopt the offshore longitudinal dike to implement Bao Tan and urge to become silted up with enclosing and cultivating, the offshore longitudinal dike adopts the jackstone dike more.Because its armour rock behaviour at sea is poor, the wave is high that part need adopt that weigh hundreds of kilograms piece stone or concret block could satisfy anti-unrestrained stability requirement for the depth of water, and the construction costs costliness of the required cubic meter of stone of every linear meter(lin.m.) and artificial block, so, traditional higher, great in constructing amount, poor safety performance of jackstone dike longitudinal dike beach protection and siltation promotion construction costs, and year maintenance capacity and maintenance expense are high.
Goal of the invention of the present invention is to provide a kind of permeable sand, cost is cheap relatively and can effectively subdue the permeable pile type offshore dam of wave energy.
The present invention adopts following technical scheme to realize its goal of the invention:
The present invention is a kind of permeable pile type offshore dam that is used for beach protection and siltation promotion, is arranged by many piles 1 to form, and is provided with empty gap 2 between stake and stake.
Compared with prior art, the present invention has following advantage:
1. the present invention can subdue wave energy, changes the ripple attitude.Often occur breaker on the offshore beach, flow turbulence is violent, causes the seashore scour.After building offshore pile dike, be subjected to the pile body drag effect, wave energy is obviously subdued, under shallow water limit wave conditions, wave height sound transmission coefficient (behind the dike before wave height and the dike ratio of wave height) can reach 0.5~0.6, wave energy (square proportional with wave height) attenuation factor can reach 0.25~0.36, and promptly the wave energy behind the dike only is about 25%~36% before the dike.Moreover, wave by offshore pile dike after its ripple condition change has also taken place, by the breaker that has strong turbulent fluctuation before the dike, change into the less advancing wave of fluctuation underflow speed, thereby the protection beach face is corroded by the wave scour no longer, reaches the purpose of Bao Tan.The permeable sand of the present invention can be guaranteed that Sha Yuan enters to enclose and cultivate the district.Enclose and cultivate the key of short silt engineering, on the one hand good flow dynamic condition will be arranged, fall to becoming silted up in order to silt, enough husky sources then should be arranged on the other hand, both are indispensable.Offshore pile dike not only can be subdued wave, improves the flow dynamic condition, forms good silt alluvial environment behind the dike, simultaneously because of its permeable sand, does not influence silt and enters alluvial district behind the dike with tidewater, for project of cultivation provides abundant husky source.Cost of the present invention is cheap relatively.The construction costs of the every linear meter(lin.m.) of permeable pile type offshore dam of the present invention is starkly lower than the cost of every linear meter(lin.m.) piece stone or artificial block jackstone dike.
2. the present invention is defined as air permeability rate
Figure A0110823600041
Air permeability rate is limited between 0.2~0.6, particularly air permeability rate is limited to 0.3~0.5 between after, the present invention can subdue wave effectively, can reduce again with the stake quantity, further reduced construction costs.

Fig. 3 is the embodiments of the invention vertical views.
Fig. 4 is the another embodiment of the present invention vertical view.
With reference to the accompanying drawings, embodiment of the present invention being done one describes in detail:
The present invention is a kind of permeable pile type offshore dam that is used for beach protection and siltation promotion, is arranged by many piles 1 to form, and the arrangement of these many piles 1 can become camber line shape, also can line up two rows, three rows, and even more rows, is provided with empty gap 2 between stake and stake, and is of the present invention
Figure A0110823600042
Value be defined as 0.2~0.6, be preferably 0.3~0.5, for example, this value is chosen as 0.2,0.3,0.4,0.45,0.5,0.57 or 0.6.
Embodiment 1: a kind of permeable pile type offshore dam that is used for beach protection and siltation promotion, form by many piles 1 arrangements, these many piles 1 can be lined up two rows, three rows, and even more rows, in the present embodiment, wherein there are 4 piles 11 to be positioned at after first campshed, form multiline pile thus and arrange, between stake and stake, be provided with empty gap 2.
Embodiment 2: a kind of permeable pile type offshore dam that is used for beach protection and siltation promotion, form by many piles 1 arrangements, these many piles 1 can be lined up three rows, three rows, and even more rows, be provided with empty gap 2 between stake and stake, in the present embodiment, stake 1 is arranged by two rows, the stake that is in second row is positioned at side after the saturating empty gap 2 of first campshed, and the stake footpath of second campshed is greater than the width of saturating empty gap 2.

Claims (3)

1. a permeable pile type offshore dam that is used for beach protection and siltation promotion is formed by many piles (1) arrangement, it is characterized in that being provided with empty gap (2) between stake and stake.
