Description

Permanent erosion plant in river mouth

The object of the invention is to utilize natural force, and often and for good and all the sand that extra large portion deposition is gone in the many river mouths, great river of sand flow plays souring.

At present, pile up for the sand that causes the river mouth plugging reason, be that delta is to rely on to have the dredger of enough abilities to remove rapidly, if great rivers, its sand amount is very big, and it is shallow to add water level, in any case existing operation ship deals with always difficult, expense is also expensive, and therefore, real current situation almost is to remain untouched with its accumulation.Because this situation, so when general ship's navigation is only limited to full sea.Arrive the upstream gradually along with rising phenomenon on the riverbed, dangerous local dykes and dams are increased gradually, and the danger of breaking dike because of flood increases.

This be one along with the time is gone through the big more work of long more difficulty, therefore be necessary to develop as early as possible the elemental method of utilizing.What at first expect is to utilize moon gravitation, i.e. the fluctuation of tidewater is poor, but it is not enough only depending on it.There are spring tide, neap phenomenon.Therefore on the sea large and small ripple is often arranged.In order to prevent this ripple, existing wave absorption dike and mole are constructed the Yue Bodi that ripple is taken into, utilizes these ripple current, and this device must replenish seawater.

Therefore, Large Storage Tanks setting-out pond 17 is set, to replenish the gravitation energy that seawater falls, washed away in one day at least twice, and the river mouth sand was piled up, gradually upstream from end river mouth, downstream, as shown in Figure 4, offer artificial prompt water route 27 establishing two dyke central authorities, in the erosion in length and breadth of water outlet phase and use small-sized underwater sand-shifting ship (Chinese patent application 88101947.X) to realize reducing the riverbed at ordinary times, the rivers and creeks water damage is effected a radical cure fully by later on.

26S Proteasome Structure and Function to this device major part describes below.

As shown in Figure 1, all there is lowest water level (L.W in the past in sea anyplace.L) and highest water level (H.W.L), medium water level is made as (M.W.L).Bulkhead wall method for constructing in the past adopts this quadrat method; Utilize a large amount of marine stone, it is made up, form the basis, on this basis, install concrete caisson, filler in the case by the diver.There is the shortcoming of leaking from space between stone in this method, pile up the construction method for coast walls (application number 88102458.9) of area use by the concrete in water filling to the sand that is limited to of Patent Office of the People's Republic of China's application, because cement block fully enters, leakage is not had fully, therefore adopt this method.

For the seawater that cement block 8 inside that are positioned at higher level are set flows into road 5, therefore, the above part of the partial cement block end face of the reinforced concrete pile 1 of central authorities is removed (with reference to Fig. 2 A-A, B-B).

This higher level's cement block 8 is than other cement block 2 height, because of the access that seawater is flowed into road 5 is located at wall portion, so for for the purpose of strengthening, top board is set, base plate and the surrounding wall that flows into road 5.They are the same with other cement block 2, also make the back in other place and install.Therefore, making lowest water level (L.W.L) consistent is to solve by regulating from the height of the partial cement block 2 of last number.For this cause, higher level's cement block 8 and finish from each operations (separation) below the third level such as the installation of the partial cement block 2 of last number are with cement block 9, concrete in water filling, packing material 12 after, again through more than 6 months, treat that wall body fully avales, the stable height that just carries out is afterwards regulated.In addition, below higher level's cement block 8, be provided with and connect recess 4, connect convex portion 3 but needn't be provided with in the above.Cement block 8 usefulness of both sides are connected securely by steel concrete top panel 13.With packing material 12 abundant water connection compactings, apply with basic rubble 14 then, reinforced concrete box 11 is set, flow into road 5 with the seawater of both sides and be connected.

Shown in Fig. 2 c, water proof curtain 6 is installed on the wall body, imbed water proof curtain supporting tube 32 in the off-lying sea side, water proof curtain 6 is crushed on side convex wall wall 15 and the convex floor 16 by hydraulic pressure, closely be adjacent to it, when the inlet that flows into road 5 from the seawater of off-lying sea side entered tidewater with pressure and full sea towards trend water, water proof curtain 6 was taking advantage of current to shake in the seawater middle reaches, seawater can not reverse backflow, forms one-way flow.Therefore,,, also can rely on wave motion, pushing water proof curtain 6 and entering if wave is arranged even during ebb tide; During full sea, be not only inflow, wave energy also enters as shown in fig. 1, and wave is crossed on the steel concrete top panel 13 and passed through, and is accumulated in the reservoir pressure pond 17.There is the problem that shoals in design ground baseline 10 at the bottom of the pond, and therefore, should dig deeplyer at first.

It is concrete that flow velocity amplifies wave amplitude water route 19 3 faces, can not leak water, 17 seawater that overflow are stored in here from the pond, owing to be provided with the door 35 that intercepts water, before full water, can remain in this, always referring to Fig. 3, here, the material of water proof curtain 6 has the intensity of iron and steel sample again gently to the degree that can float in the water, almost can forever not corrode.Generally, have many materials available on market, mainly can enumerate special rubber, polyester, nylon etc., it is also very good that materials such as nylon are coated on the carbon fibre formed material.

In the full water occasion, because the door that intercepts water 35 water surface rising occurred, the height of door so the height of sidewall 24 should be equivalent to intercept water.

Intercepting water should be the bar gate type water valve on door 35 the structure principle, and because water is shallow, hydraulic pressure is also little, so use water proof curtain 6.

Shown in Fig. 3 C-C, on the very wide water route, be infeasible only, therefore, often its branch made proper width with a water proof curtain 6, coaster and post 36 with band miniature motor (can reverse) are suspending in midair, with coaster in the water 37 interlock, the two ends of water proof curtain 6 rope with nylon system is connected, make two horizontal ends of each water proof curtain 6 overlapping, hydraulic pressure is pressed on it on side convex wall wall 15 and the convex floor 16, keeps full water state.

Door 35 the operation that intercepts water has two aspect effects, the first is under windless condition, when ripple does not take place, owing to there is not the full sea face so high, soon take place at ebb tide, the motor reverse is fallen water proof curtain 6 simultaneously, keep the full sea seawater, the sea is mean water (M.W.L), after tidal range produces half drop, allow motor just change simultaneously, on water proof curtain volume, seawater is fallen.That is, worked fixed about 3 hours as water valve, all the other about 9 hours water proof curtains 6 are rolled-up, do not use.Another effect is to take place, in the time of can forming full water, make the action of water proof curtain when ripple.When full water, then open the door simultaneously, allow seawater fall.Seawater bends towards direct route by training wall 25 guiding; Plan line 23 by becoming midway the point 22 of being in of mild gradient gradually, washes away accreting sand by initial subvertical gradient at the bottom of the water route, enters special-purpose water route (both sides by ocean bulkhead wall 18 round).This seawater directly enters in the general seawater of off-lying sea, and the scouring force diffusion that produces because of gravity disappears, therefore, by not being the CN88102458 of the formula of crossing, two walls 18 of the concrete ocean bulkhead wall in No. 9, with it as the wall body that prevents flow of water diffusion, become and wash away special-purpose water route, isolated with the off-lying sea.So, continent during the place ahead occurs immediately, the sand that stops up the river mouth is sent to the place ahead, match with scroll-type water channel 34, sand is being taken advantage of ocean current outwardly, further outside, after this just rely on I another contrive equipment that Patent Office of the People's Republic of China applied for (application number 88101947, X)-underwater sand-shifting ship finished.Therefore, door 35 actions that intercept water are more than 6 hours, and it also is about 6 hours that water proof curtain 6 volumes are gone up state (full water lowering time).This device is after starting, because studying for a second time courses one has flunked or other thing being arranged of water route will make souring temporarily stop, the spy is provided with electrodynamic type overfall 33 for this reason.

As shown in Figure 3, rivers and creeks main flow 20 is not necessarily parallel with reservoir pressure pond 17 sometimes, is parallel or meet at right angles with the coastline (see among Fig. 3 20 ') with it so it is changed to move.

Pith with anti-tide dike 31 protection coastlines.Scroll-type water channel 34 is to spread stone on the dykes and dams surface with the sand protuberance, and dykes and dams are protected.Seawater during full sea at ebb tide, and is elongated to the distance extension of outlet, can utilize this extension, lures and makes ocean current.The trend power of two groups of water channels 34 is lumped together a step towards sending accreting sand.

As shown in Figure 4, big rivers and creeks occasion, smooth downstream part length is very long, and it is impossible that the riverbed is reduced.Therefore, can the riverbed be descended, only utilize often poor effect of natural phenomena, and can't correct irregular flow, if the central authorities of two dykes 26 offer artificial prompt water route 27 as water channel in the rivers and creeks, then shown in Fig. 4 b, the ship navigation possibility that becomes, need not rely on manpower, utilize application number, can make to rise on the riverbed once again to stop for the small-sized water-bed sand among the 88101947.X promotes ship.By this victory water route 27 is set, secondary levee dam 28 is set, the earth 29 of deposition directly becomes the farmland, and bring back to life in many farmlands, and government investment begins to regain.

River mouth, the big rivers and creeks permanent erosion device that utilizes the present invention to propose can be obtained following effect:

1. can solve unsolved for a long time river mouth clogging.

2. can realize that the riverbed descends.

3. irregular flow particularly disappears in the burst the dikes danger of bottom of curve part, can not cause brokenly dike.

4. shipping recovery.

5. harness the river thoroughly in the rivers and creeks, and drainings such as dwelling house ground, farmland are good.

6. as byproduct, new land produces, and can build up desirable city farmland.

7. the farmland recovery is expected to recoup capital outlay near many riverss and creekss.

8. owing to utilizing natural force, so dyke is built expense and the upkeep cost of harnessing the river are very low, good economical benefit.
