Abstract
The invention discloses a river training method through wind. The method includes first arranging vertical shaft type wind high-pressure pumps at windward positions of jetty heads at two shores of the river every 1km to generate high-pressure gas, and delivering the high-pressure gas to the river bottom through a delivery pipeline which should be sunk to the river bottom longitudinally along the main flow direction of the river. The principle that a large amount of rising bubbles can be generated when the high-pressure gas is erupted from the river bottom is adopted, the bubbles can carry sand at a main channel of the river bottom to rise continuously, and the sand is difficult to deposit due to continuous generation of the gas and flows to the ocean without reservation under scour of the water flow. After a long time, underwater river beds can form a narrow and deep main channel at the position of the delivery pipeline, and surrounding silt collapses gradually towards the main channel direction along with continuous sapping of the channel until the whole channel saps.
Description
Technical field: a kind of method that the present invention relates to river training, especially a kind of method of wind-force river training.
Background technology: the river that some sand content is large, because silt amount is greater than sand discharge amount, causes riverbed to raise year by year, often exceeds several meters more than than ground outside dike, becomes on the ground " hanging river ".When running into extraodinary flood, very easily inrush and burst even to cause to change its course.Each breach or change its course and all cause extremely very grave disaster to the common people at that time.For this reason, guarantee that riverbed is not raised, do not burst, do not change its course, the application life extending current stream is to greatest extent cardinal task.The Yellow River of China is exactly the very large river of sand content, " flow-sediment regulation " that Yellow River In Recent Years is all implemented every year, one of preferred version that the current exactly downstream river course that brings the Yellow River under control does not deposit, this utilize Xiaolangdi Dam Project under let out the huge energy that great deal running water produces, washing away the method for downstream river course silt, is control the theoretical another great practice in the new period in river ancient times " clearing sands with converging flow ".For a certainty earth-shaking change is created to the dredging subtracting sand and downstream river course of becoming silted up that subtracts of reservoir, significant role is served to the application life extending existing stream.
But " flow-sediment regulation " about the first quarter moon by a definite date carried out annual June, be just in time the prime time that the Lower Reaches of The Yellow River masses use water irrigated farmland in a large number, look at Huanghe water (2,600,000,000 m with great strength and vigour
3left and right) pouring in sea and can not use in vain, larger along yellow masses' suggestion.In addition, except " flow-sediment regulation " period river channel sedimentation alleviates, during low discharge, alluvial is still more serious at ordinary times.Can when low discharge at ordinary times, does the sediment transport that also can reach " flow-sediment regulation " subtract the effect of sand, river training? one running time that can shorten " flow-sediment regulation ", the Huanghe water of saving is applied in industrial and agricultural production to greatest extent, plays its maximum value.Two can continue to subtract sand, river training, extend the application life of current stream to greatest extent.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the invention provides a kind of cost low, implements the method for simple wind-force river training.
For achieving the above object, the technical solution used in the present invention is: a kind of method of wind-force river training, first at the place windward of two sides, river course abutment, at interval of 1km, vertical axis type wind high pressure pump is installed and produces gases at high pressure, and then utilize conveyance conduit to be transported to river bed gases at high pressure.The installation position of conveyance conduit longitudinally should sink to river bed (optimum position is on main stem) by the main flow direction along river course.Steam vent on conveyance conduit is arranged on the left and right sides of pipe, steam vent interval 1m, diameter 3mm the position opening (so not easily blocked by silt and also can not cause float tube phenomenon) of the upper miter angle of deflection, conveyance conduit is that super thick increases the weight of steel tubes (durable and can never float tube).Utilize gases at high pressure when the bottom sprays, the principle of a large amount of rising bubbles can be produced, bubble will sweep along the silt at major trough position, river bed constantly to rise quickly floating, because gas can produce endlessly, so silt gets off with regard to being difficult to deposition, under the washing away of current, it will the bosom in input sea of " outspoken ".Year in and year out, riverbed under water will form a narrow dark main stem at conveyance conduit one line, and along with the continuous incision in riverbed, silt around slowly will cave in major trough direction, until whole channel lowering.Especially, when there is large discharge river, stirring husky sand surfing, the effect expectation of river training can be better.
The present invention disturbs Sha Qihe with giant and weeds wushu and stir husky device and compare, without the need to manual operation, without the need to fuel consumption or electric power, without the need to corollary equipments such as ships, and energy-saving safety.Disturb sand with the stream that sluices under reservoir large discharge to compare, without the need to manual operation, without the need to fuel consumption or electric power, without the need to building the corollary equipment such as reservoir, sluice gate, energy-saving safety, reduced investment.
Accompanying drawing illustrates:
Fig. 1 is present device connection diagram
Fig. 2 and Fig. 3 is fundamental diagram of the present invention.
Fig. 4 is the structural representation of conveyance conduit.
Detailed description of the invention:
As shown in Figure 1-Figure 3, vertical axis type wind high pressure pump 2 is highly about 10 meters (cost low, easy to maintenance, do not affect by wind direction) its gases at high pressure produced can first be stored in holding vessel 4, is then transported to river bed through steel pipe 3.The pipe thickness of steel pipe 3 is 7-10 millimeter, diameter 100 millimeter.At the place windward of two sides, river course 1 abutment, at interval of 1km, vertical axis type wind high pressure pump 2 is installed and produces gases at high pressure, and then utilize steel pipe 3 to be transported to river bed gases at high pressure.The installation position of steel pipe 3 longitudinally should sink to river bed by the main flow direction along river course, and optimum position is on main stem 6.
As shown in Figure 4: conveyance conduit is that super thick increases the weight of shape tube, it has pore 5, and the thickest part is 10 millimeters, most thin section is divided into 7 millimeters.Thick part under, thin part is upper.
