Abstract
The invention relates to a wave type wave-absorbing dam which comprises a stair type dam bottom, a wave type grid wall and a wave-resisting wall, wherein the wave-resisting wall is mounted at the top end of the stair type dam bottom; the wave type grid wall is vertically mounted on the stair surface of the stair type dam bottom; the horizontal cross section of the wave type grid wall is wave-shaped; the wave type grid wall consists of an arced wall at the entrance, an arced wall at the final point and an arced wall in the middle section; the central angle of the arced wall at the entrance is 60 degrees; the central angle of the arced wall in the middle section is 120 degrees; the arced wall at the final point is connected with the wave-resisting wall. Due to the adoption of the stair type dam surface, the functions of roughening the protecting surface and eliminating the energy are achieved, and a part of the wave energy can be eliminated; due to the adoption of a wave type grid wall structure, spindrift and vortexes are formed after water flows into the dam, and then the wave is crushed and collided to achieve the energy elimination function; as the wave type grid wall is combined with the stair type dam surface, the wave entering the grid wall is subjected to dual energy elimination, the wave is prevented from raising high and washing the dam bottom, the coast is prevented from being scoured, and a good coast protection function is achieved.
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 lift in husky and sediment tide transport situation at the broken wave of offshore, 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, must take engineering measure to be protected bunding.
The key of bunding preventive works is the waves that disappear, and can also stop sediment tide transport simultaneously.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. at present, and these dyke forms have reached wave resistance energy dissipating and the requirement of people to 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, take the wave of pouring into riverbank or seashore as energy dissipating object, adopts two-stage energy dissipating, and attenuating shock wave ratio is good.
The technical solution used in the present invention is:
Wave wave-absorbing bank, at the bottom of including 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 radius of interlude circular arc wall.
The thickness of wave hoarding be interlude circular arc wall radius 1/12.
Advantage and effect that the present invention has are:
1, the present invention is wave wave-absorbing bank, at the bottom of including 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 faces, 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.Staged dike face plays the effect of mask roughening and energy dissipating, 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, and the wave entering between hoarding is carried out to dual energy dissipating, thus reduce wave climb and to washing away at the bottom of dike.For promoting the degree of viewing and admiring of current, at the bottom of staged dike, can coordinate the construction of civic landscape main road to form People's Bank of China's view pavement, 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 that needs protection of wave, also can be applicable to by riverfront, Offshore street, in conjunction with civic landscape, strengthen hydrophily, promote people's water harmony, also can be positioned over city inland river turning, reach the effect of flood control.The present invention can prevent that seashore is by scour, plays the effect of good protection seashore, and ecology is combined with hydraulic engineering, as coast landscape, brings certain economic benefit for coastal cities, has 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, the wave structure that the makes full use of hoarding energy dissipating of carrying out interacting between 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 be interlude circular arc wall radius 1/12, distance between adjacent wave hoarding is 1.5 times of radius of interlude circular arc wall, this distance makes the mobile 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 chamber.
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: four groups of wave hoardings are installed on staged dike face, and 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 is that inclination angle is the right-angled triangle of 30 °, good stability.It is highly 40cm.Some ladders are set on the slope at the bottom of dike, and the cross section of every one-level ladder 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.
