Technical field
The present invention relates to harbour mole technical field more particularly to a kind of multi-functional anti-waves suitable for height domain containing the sea of sand
Dike.
Technical background
There is extremely profound significance at harbour as important transport hub, for economic development.According to the relevant information,
Global 35 international cities, wherein having 31 is the international city to grow up because there is harbour, and the whole world
The 50% of wealth concentrates on coastal port city.However for China part coastal port (such as PORT OF SHANGHAI, Ningbo-Zhoushan Port
Deng) for, due to being in the sea area of Gao Hansha, inevitably generate siltation phenomenon.The reason is that reach port
Interior mooring conditions generally require to build breakwater other than basin, change local hydrodynamic condition, cause to affect script
Coastal line.
Since water volume flow rate is lower on the inside of breakwater, silt is easily settled, it is thus possible to deposit in the position.Once hair
The phenomenon that life is deposited, then will lead to water depth deficiency in port, influences boat trip and berths.
Currently, solving the problems, such as there are mainly two types of the modes of harbor siltation, one is to establish numerical value according to local flow characteristics
Model is to take optimal design, but which does not have universality, once and HYDRODYNAMIC CHARACTERISTICS has change after actually building up, then
It can not make the most of the advantage；Secondly for using periodically dredging by the way of, but (annual cost is up to several with costly for which
Million) disadvantage for, not having sustainability (needing long-term dredging up to decades), destroying all various aspects such as ecology, is a kind of
The method done something against one's will.According to the above status, it is known that find it is a kind of low cost, significant effect and technically it is easy to accomplish
Solution has great real engineering significance.
Summary of the invention
The present invention to solve the above-mentioned problems, provides a kind of design of multifunctional jetty suitable for height domain containing the sea of sand
Thinking can be applied to all kinds of harbours, solve the problems, such as that basin is easy siltation on the inside of breakwater.To achieve the goals above, this hair
It is bright to adopt the following technical scheme that
Multifunctional jetty suitable for height domain containing the sea of sand includes breakwater main body, hydrodynamic force interchange channel, turbine generation
Machine and control valve；The hydrodynamic force interchange channel is the pipeline for being laid with and running through in advance breakwater main body；Hydrodynamic force exchange is logical
It is upper layer and lower layer that road is arranged in breakwater main body, and every layer includes multiple pipelines；It is logical that the control valve is mounted on hydrodynamic force exchange
The side end of heading sea in road, turbogenerator are installed at the back wave side outlet of hydrodynamic force interchange channel；The control valve is single
To valve, the top level control valve side water body that only allows to head sea flows into and carries on the back unrestrained side, and lower layer only allows to carry on the back unrestrained side water body inflow and heads sea side.

Interchange channel is lower than sea level height when ebb tide.
Preferably, the pipeline exit of lower layer's hydrodynamic force interchange channel is connected with conduit, the conduit for all or
The hyper-concentration flow flowed out in the export port of part.
The coastal line self-adjusting method in the high domain containing the sea of sand that the invention also discloses a kind of based on the breakwater:
1) in floodtime, since the water level on the outside of breakwater gradually rises, silt content relatively low seawater in upper layer is logical
It crosses upper pipeline and enters basin, while rotating turbine being driven to generate electricity；After energy is converted, water body kinetic energy is consumed, no
Excessive influence can be generated to water body in port；
2) during ebb tide, since water body is stablized in basin, silt natural subsidence, therefore close to the silt for carrying on the back unrestrained side sea bed
Concentration is higher, which is flowed out by lower layer's pipeline, whole to reduce silt content in port；Meanwhile driving turbine
Rotation generates electricity and plays the role of energy dissipating；
Since the water body sediment concentration for flowing into basin is smaller, and the water body sediment content for flowing out basin is higher, therefore every time
The silt net flux of fluctuation tide is negative value；The silt net flux of each fluctuation tide is scaled annual silt net flux, in adjustment
The cross-sectional area A of layer pipeline1With the cross-sectional area A of lower layer pipeline2Value, survey annual silt net flux with history annual
Sediment siltation amount offsets.
And during non-fluctuation tide, the present invention is similar with the working principle of common breakwater.
Breakwater main body of the invention can exist inside levee body when pouring in advance by taking common gravity type sloping breakwater as an example
It is laid with two layers of pipeline up and down as hydrodynamic force interchange channel.In conjunction with sediment content vertical distributing rule in water body, it is believed that in weight
Under power settlement action, the sediment concentration close to bottom surface sea bed is higher, and the sediment concentration by approximately level is lower.At high tides, water flow
Basin can only be flowed into from upper pipeline, for water flow at this time because being located at upper layer, sediment concentration is relatively low；Water flow can only be from ebb tide
The outflow of lower layer's pipeline, for water flow at this time because gravitational settling acts on, sediment concentration is relatively high.In daily fluctuation tide circulation,
Silt is constantly carried in port, can solve the problems, such as siltation in port.The hyper-concentration flow flowed out in port simultaneously can pass through catheter drainage
To other places, while it can solve that may be present head sea under partial picture and surveying local scour problem.
In view of hyper-concentration flow possesses the momentum bigger than general water flow, on the one hand, when hydrodynamism is stronger outside port
When, by transmitting, it will affect mooring conditions in port or cause excessively to wash away problem in port, it is therefore desirable to is logical in hydrodynamic force exchange
Energy dissipator is set at road inside outlet；On the other hand, it is contemplated that tide energy is a kind of clean energy resource and current marine resources
The big hot spot direction of one utilized, therefore, the present invention merges power generator with energy dissipator, is installed in the form of power generation turbine
In breakwater inside pipeline exit, while at the sea bed of inside, setting cement block or stone protection bottom prevent from washing away.
The present invention uses technical solution as above, and has the advantage that
1. multifunctional jetty of the present invention is designed for high domain containing the sea of sand, can effectively solve inside and outside harbour
Erosion and deposition imbalance problem.
2. the breakwater can also utilize tide energy in addition to having the function of that normal breakwater had disappears other than wave, sediment trapping etc.
It generates electricity, while avoiding being mounted with energy dissipator, kill two birds with one stone.
3. technical problem is not present when actually pouring for the breakwater, it is easy to implement.
4. power generation turbine and check valve are mounted on hydrodynamic force interchange channel both ends by the breakwater, convenient for later period maintenance and
Replacement.
