Description
Technical field
The present invention relates to a kind of wave wave-absorbing bank.
Background technology
Wave is one of main dynamics factors causing Coastal erosion.Especially, under the broken sediment winnowing of offshore and sediment tide transport situation, major part is etched silt to away from area, bank diffusion And Movement, causes the continuous scour of seashore to retreat, and then harm bunding safety.Therefore, engineering measure must be taked to be protected bunding.
The key of bunding preventive works is the waves that disappear, and can also stop sediment tide transport simultaneously.Current bunding often adopts vertical type wave-absorbing bank, oblique wave formula wave-absorbing bank, floating wave-absorbing bank and adopts heteromorphic block energy dissipating etc., and these dyke forms reach wave resistance energy dissipating and people to the requirement of view, but hydrophily is poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wave wave-absorbing bank, and wave-absorbing bank of the present invention is to pour into the wave on riverbank or seashore for energy dissipating object, and adopt two-stage energy dissipating, attenuating shock wave ratio is good.
The technical solution used in the present invention is:
Wave wave-absorbing bank, includes at the bottom of staged dike, wave hoarding and wave wall.Wave wall is installed on the top at the bottom of staged dike; The quantity of described wave hoarding is at least three groups, wave hoarding is vertically installed on the cascaded surface at the bottom of staged dike, the horizontal section of wave hoarding is waveform, wave hoarding is made up of entrance circular arc wall, destination county circular arc wall and interlude circular arc wall, the central angle of entrance circular arc wall is 60 °, the central angle of interlude circular arc wall is 120 °, and destination county circular arc wall is connected with wave wall.
Distance between adjacent wave hoarding is 1.5 times of the radius of interlude circular arc wall.
The thickness of wave hoarding is 1/12 of the radius of interlude circular arc wall.
The advantage that the present invention has and effect are:
1, the present invention is wave wave-absorbing bank, includes at the bottom of staged dike, wave hoarding and wave wall.Upstream face at the bottom of staged dike is provided with some grades of right angle steps and forms staged dike face, and wave wall is installed on top at the bottom of staged dike, and wave hoarding is vertically installed on the staged dike face at the bottom of staged dike.The effect of mask roughening and energy dissipating is played in staged dike face, can eliminate a part of wave energy.Wave hoarding structure makes current enter the rear formation spray and vortex, makes wave breaking and shock, reaches energy dissipating effect.Wave hoarding combines with staged dike face, carries out dual energy dissipating to the wave entered between hoarding, thus reduce wave climb and to washing away at the bottom of dike.For promoting the degree of viewing and admiring of current, the construction of civic landscape main road can be coordinated at the bottom of staged dike to form People's Bank of China's view pavement, and visitor can stop and play on ladder, forms the hydrophilic environment of people's water harmony.This wave wave-absorbing bank both can be applicable to larger seashore, the riverbank needing protection of wave, also can be applicable to by riverfront, Offshore street, in conjunction with civic landscape, strengthen hydrophily, promote that people's water is harmonious, also can be positioned over city inland river turning, reach the effect of flood control.The present invention can prevent seashore by scour, plays well protection seashore effect, and ecology is combined with hydraulic engineering, as coast landscape, for certain economic benefit is brought in coastal cities, have certain promotional value.
2, the horizontal section of wave hoarding of the present invention is waveform, and wave hoarding is made up of entrance circular arc wall, destination county circular arc wall and interlude circular arc wall, and entrance circular arc wall central angle is 60 °, and the central angle of interlude circular arc wall is 120 °.Such structure can make current enter more smoothly between hoarding, and the wave structure making full use of hoarding carries out the interphase interaction energy dissipating of water and water, be conducive to simultaneously at the bottom of hoarding and dike be connected firmly stable.
3, the thickness of wave hoarding of the present invention is 1/12 of the radius of interlude circular arc wall, distance between adjacent wave hoarding is 1.5 times of the radius of interlude circular arc wall, this distance makes the flowing connectedness of current between hoarding best, and the mutual collision of current between wave hoarding is simultaneously more abundant, energy dissipating effect is the strongest.
Model testing
Model testing is carried out in Agricultural University Of Shenyang's water conservancy institute hydraulic test room.
Test model is made up of three parts: wave wave-absorbing bank, dull and stereotyped common dike face and simple and easy wave simulator.This three part all adopts pmma material to make, and is jointly placed in rectangle organic glass groove.
Wave wave-absorbing bank: staged dike face is installed four groups of wave hoardings, the entrance circular arc wall central angle of wave hoarding is 60 °, and the central angle of interlude circular arc wall is 120 °.The radius of entrance circular arc wall, destination county circular arc wall and interlude circular arc wall is 6cm, and the distance between adjacent hoarding is 9cm, and hoarding thickness is 5mm.End face structure at the bottom of dike to be inclination angle the be right-angled triangle of 30 °, good stability.It is highly 40cm.Slope at the bottom of dike arranges some ladders, and the cross section of every step is right-angled triangle, and its shortest right-angle side is 4cm, and the angle corresponding with it is 30 °.In model, wave wall height is 20cm, and width is identical with ladder width; Wave hoarding height is 20cm, and model lateral length is 50cm.
Dull and stereotyped common dike face: lateral length 50cm, 30 °, inclination angle, slope, dike face vertical height is 40cm.
For producing wave continuously, make simple and easy wave simulator by oneself.As shown in Figure 4, simple and easy wave simulator is by disturbance plate 4, cam 6, couple axle and motor 5 four part composition, general principle utilizes motor to manufacture the internal disturbance of current as power-equipment, operated by driven by motor cam, cam drives disturbance plate by couple axle, makes disturbance plate swing, so that forms wave.
Take bottom land as benchmark, test with three of 15cm, 17cm, 19cm kinds of different water depths respectively, motor rotation frequency is 90r/min, to carry out contrast test to wave wave-absorbing bank and the common dike face of flat board under identical flow condition.
Wave run-up chaining pin measures.Wave run-up is used
δrepresent, the wave run-up of its middle plateform common dike face is used
δ prepresent, the wave run-up of wave wave-absorbing bank is used
δ b represent, wave run-up abatement rate (abbreviation attenuating shock wave ratio) is used
k brepresent, attenuating shock wave ratio is defined as
k b=(
δ p-
δ b)/
δ p.
Scheme one: when the depth of water is 15 ㎝, two kinds of form dike face wave run-up measured datas are shown in Fig. 5 (unit: cm).
Scheme two: when the depth of water is 17 ㎝, two kinds of form dike face wave run-up measured datas are shown in Fig. 6 (unit: cm).
Scheme three: when the depth of water is 19 ㎝, two kinds of form dike face wave run-up measured datas are shown in Fig. 7 (unit: ㎝).
Through test data analyzer, wave wave-absorbing bank attenuating shock wave ratio reaches 79% ~ 85%.
As the above analysis, wave-absorbing bank of the present invention significantly can reduce wave run-up.
