Description
Technical field
The invention belongs to wave resistance mitigation and coastal engineering field, particularly a kind of simple and easy floatation type wave suppression arrangement.
Background technology
Account for earth surface to amass in the ocean of 70.9% and contain rich in natural resources, mineral resources, living resources, water resource and other various resources.Along with the development and progression of mankind's science and technology, land resource has been difficult to the needs meeting human development, and ocean is becoming the second space of human development, while the demand of the mankind to ocean is increasing, also proposes more and more higher requirement to marine engineering.There are very long coastline and abundant marine resources in China, and there are nearly 3,000,000 Km in the marine site administered
2(being equivalent to 1/3 of territory, China land).China will resolve population, resource and environment problem, and the important outlet reaching medium-developed country at mid-21st Century moves towards ocean exactly.
Meanwhile, port construction, as traditional coastal engineering category, along with the development of economy and technology, also encounters unprecedented opportunity to develop.Under the trend that international trade demand and ships that transport keep the large-scale development, the scale at harbour, by increasing, requires also more and more higher to fairway depth.And after the natural deep sea harbour location exploitation totally of self limited shielding, port construction progressively enters the depth of water marine site that the wave is high.In view of deep water Open Sea bad environments, traditional hydro-structure is because construction costs is high, technical sophistication, constructional difficulties etc. can not adapt to deep water port development need.Along with composite demands such as coastal environment protection, sightseeing tour, aquacultures, there is great change about the idea of seashore and port development in people.In order to adapt to the depth of water, the wave is high, ground weak, introduce exchange of seawater improves water quality environment and cheap demand, and port structure form will to new structure pattern development such as cancelled structure, energy dissipation type structure and Mobyneb structures.
Mole is a kind of conventional unrestrained device that disappears, can ensure that there is the enough depth of water at harbour and maintains the water surface to be steadily convenient to safety of ship and to berth and the hydraulic structure of operation, but these traditional hydraulic structures normally gravity, expenditure of construction can increase severely along with the increase of engineering Larger water depths, and in work progress, all need large-scale special machinery, construction more complicated, once destroy, repairs difficulty especially.On the other side, floatation type wave suppression arrangement has obvious advantage and feature: 1) cost is low, and consume material is few; 2) install simply, require low to sea-floor relief, be convenient to mobile and dismounting; 3) environmental friendliness, affects little on seawater and biomass circulating.Since the seventies, along with the design success of the floatation type wave suppression arrangement of many dexterities, various floating wave suppression arrangement is applied in succession, the floating wave suppression arrangement structural shape that current countries in the world put forward mainly can be divided into floating box type, float-type and floating raft type three kinds, use result for many years shows, this type of mole is safe and reliable.But, for current floating wave suppression arrangement form of structure, its subject matter faced is: fair to the shielding effect of shortwave (the ratio L/B<4 that wavelength is wide with device), but still very high to the transmitance of long wave (L/B>6).
Summary of the invention
Technical problem to be solved by this invention is: overcome above-mentioned existing anti-wave technology cost control, long construction period, on water circulation impact larger, and existing floating shielding is to weak points such as the anti-weave efficiency of long wave are low, a kind of simple and easy floatation type wave suppression arrangement is provided, it adopts exposed throughout type, multistage energy dissipating principle, thus reach better wave dissipation effect, be easy to install and move, have higher reliability, it is less to the aesthetic effects of water front simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of simple and easy floatation type wave suppression arrangement, comprises top board, base plate, side board, barrier board, column, energy dissipating room, tire, concave surface arc, porous water-stop sheet, convex surface arc and anchor chain.It is characterized in that: top board and base plate lay respectively at top and the bottom of wave suppression arrangement, adopt column to connect top board and base plate; The both sides of wave suppression arrangement adopt the side board of hollow out to close, and front and back adopt barrier board to close; Wave suppression arrangement inside adopts barrier board to be separated into three energy dissipating rooms; Regularly arranged tire is adopted to carry out wave absorption in one-level energy dissipating room; Regularly arranged arc is adopted to carry out wave absorption in secondary energy dissipating room; Lay two row's porous water-stop sheets in three grades of energy dissipating rooms, and between water-stop sheet, fill artificial aquatic weed carry out wave absorption; Wave suppression arrangement entirety floats on the water surface, and adopts anchor chain to be fixed on seabed.
The simple and easy floatation type wave suppression arrangement of described one, is characterized in that: adopt convex surface arc and concave surface arc to be staggered in secondary energy dissipating room.
Taking into full account natural conditions (as wind, wave, tidal level, ocean current), material condition (as the strength of materials and application life), after the requirement of service condition (as diffraction, reflection, transmission and more unrestrained) and execution conditions (as ship machine equipment and construction technology), main body of the present invention adopts the design of the anti-ripple case of floating.Its main energy dissipating object is the wave that wavelength is longer, wave height is larger in ocean and lake, utilizes buoyancy aid to reflect, conversion, to absorb and dissipation wave energy is key problem in technology to reduce the energy of transmission wave.The rationally energy dissipating of application porous, wave and flexible material effect energy dissipating in design for this reason, and the feature making full use of wave generation turbulent flow and blending carries out self-energy dissipating.Simultaneously, in device, hierarchical classification adopts different materials to weaken wave force successively, embody the characteristic of multistage energy dissipating in design, design is made to reach defence wave to the invasion and attack of water front and harbour water area, ensure that bank has stable waters, be convenient to boats and ships and stop mooring, carry out the purpose of design such as cargo handling operation and upper and lower passenger smoothly.
The simple and easy wave suppression arrangement inner space that the present invention proposes is divided into three energy dissipating rooms, as shown in Figure 2, is respectively one-level energy dissipating room, secondary energy dissipating room and three grades of energy dissipating rooms.In one-level energy dissipating room, packing material is junked tire, and tyre cord fabric is set to the many rows perpendicular to base plate, and often row is divided into multilayer, there is a determining deviation between row and row, and is staggered between row and row.Because tire has good toughness, powerful wave impact can be resisted, and have comparatively macrovoid and inner space, can, while obstruction water movement, make, between inside tires or tire, circulation and turbulent flow occur.In addition, the multi-layer intercrossed arrangement of tire also promotes to collide energy dissipating between current more.Convex surface arc and concave surface arc apportion is adopted to be staggered in secondary energy dissipating room.The arrangement of each layer arc repeats to lay according to certain rule, a fixed gap is there is between every layer of arc, make current flow to lower one deck arc by space after arc collision energy dissipating and again act on energy dissipating, so, while constantly changing the direction of a stream of water, in turn ensure that overcurrent, make current reach the effect of disorderly energy dissipating.The material used in three grades of energy dissipating rooms comparatively front two-stage energy dissipating room degree of porosity is less, and namely between porous water-stop sheet, fill artificial aquatic weed, the density of artifical flume can according to circumstances adjust.Three grades of energy dissipating chamber interior porous water-stop sheets are divided into twice, artificial aquatic weed is filled in space between water-stop sheet and barrier board, current and artificial aquatic weed and artificial water-stop sheet interact, the kinetic energy of water body and potential energy friction and between pasture and water and current energy transferring process in consume further.
When not having wave action, simple and easy floatation type wave suppression arrangement remains static, and buoyancy suffered by it and gravity reach an equilibrium state, and the upper plane of wave suppression arrangement is a little more than sea level.When wave is delivered to wave suppression arrangement, wave current, by the transmission part of barrier board, enters one-level energy dissipating room and tire and interacts and form turbulent flow and reflexion of wave, consume part wave energy.Further, current carry residue wave energy and enter secondary energy dissipating room, the direction of motion of water particle and velocity magnitude in arc forcibly changing current, the current contrary in the formation direction, peripheral region of arc and local turbulent, make full use of the self-energy dissipating mechanism of wave.Finally, three grades of energy dissipating rooms, make full use of the material behavior of flexible material-artificial aquatic weed, reduce the degree of porosity of three grades of energy dissipating rooms, artificial aquatic weed and wave are fully acted on, effectively utilize the transmission of energy between frictional force and kinetic energy and potential energy, reach effect of energy dissipation.Meanwhile, when wave action is in time of the present invention, rectangular box is under the acting in conjunction of wave and hawser system, and its top planes can tilt and then be formed breaker face, raises crest height, causes wave breaking to consume wave energy.
The invention has the beneficial effects as follows:
The present invention is applicable to coastal waters and the relatively poor place of ocean engineering foundation construction, have employed exposed throughout type barrier board and multistage energy dissipating design, utilizes the wave absorption materials and structures of wave suppression arrangement inner stages wave absorption indoor location, the effective wave dissipation effect increasing device; Device major part is positioned at below water surface curve, less to the aesthetic effects of water front; The design's form is simple, adopts floatation type structure, is convenient to manufacture, installation and maintenance.
