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

A kind of method of wind-force river training

Technical field: the present invention relates to a kind of method of river training, especially a kind of method of wind-force river training.

Background technology: the river that some sand content is large, because the silt amount greater than the sand discharge amount, causes the riverbed to raise year by year, often exceed several meters more than than the outer ground of dike, become on the ground " hanging river ".When running into extraodinary flood, very easily inrush and burst even cause and change its course.Burst at every turn or change its course all and to have caused extremely very grave disaster at that time the common people.For this reason, guarantee that the riverbed do not raise, do not burst that do not change its course, be cardinal task the application life that prolongs to greatest extent current stream.The Yellow River of China is exactly the very large river of sand content, annual " flow-sediment regulation " all implemented on the Yellow River In Recent Years, one of preferred version that the current exactly downstream river course that brings the Yellow River under control does not deposit, this utilization let out the huge energy that great deal running water produces under the Xiaolangdi Dam Project, washing away the method for downstream river course silt, is to control the another great practice of river theory in the new period ancient times " clearing sands with converging flow ".For a certainty the dredging subtract sand and downstream river course of becoming silted up of subtracting of reservoir has been produced earth-shaking variation, to having played significant role the application life that prolongs existing stream.

Yet by a definite date " flow-sediment regulation " about first quarter moon that carries out annual June just in time is the prime time of a large amount of waters of Lower Reaches of The Yellow River masses irrigated farmland, seeing Huanghe water (2,600,000,000 m with great strength and vigour ³About) pouring in the sea and can not use in vain, larger along yellow masses' suggestion.In addition, river channel sedimentation alleviated during " flow-sediment regulation ", at ordinary times low discharge time alluvial was still more serious.Can be in the situation of low discharge at ordinary times, does the sediment transport that also can reach " flow-sediment regulation " subtract the effect of sand, river training? one can shorten the running time of " flow-sediment regulation ", the Huanghe water of saving is applied in the industrial and agricultural production to greatest extent, brings into play its maximum value.Two can continue to subtract sand, river training, prolong to greatest extent the application life of current stream.

Summary of the invention: for above-mentioned the deficiencies in the prior art, it is low to the invention provides a kind of cost, 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, at first locate facining the wind of two sides, river course abutment, every interval 1km, vertical axis type wind high pressure pump is installed is produced gases at high pressure, and then utilize gases at high pressure conveyance conduit to be transported to the river bed.The installing the position and should vertically sink to along the main flow direction in river course river bed (optimum position is on main stem) of conveyance conduit.Steam vent on the conveyance conduit is arranged on the left and right sides of pipe, steam vent interval 1m, the position opening of diameter 3mm and the upper miter angle of deflection (be difficult for like this stopped up also can not cause the float tube phenomenon by silt), conveyance conduit are the super thick steel tubes (durable and can never float tube) that increases the weight of.When utilizing gases at high pressure to spray at the bottom, can produce the principle of a large amount of rising bubbles, bubble will swept along the silt at major trough position, the river bed come-up that constantly rises quickly, because gas can produce endlessly, silt just is difficult to deposit so, under the washing away of current, the bosom in the input sea that it will " 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 on every side will slowly cave in to the major trough direction, until whole channel lowering.Especially in the situation that large flow river occurs, the effect expectation meeting of stirring husky sand surfing, river training is better.

The present invention disturbs Sha Qihe with giant and weeds wushu and stir husky device and compare, and need not manually-operated, need not fuel consumption or electric power, need not the corollary equipments such as ship, energy-saving safety.Disturb sand with sluicing stream under the large flow of reservoir and compare, need not manually-operated, need not fuel consumption or electric power, need not to build the corollary equipments such as reservoir, sluice gate, energy-saving safety, reduced investment.

Fig. 1 is the present device connection diagram

Fig. 2 and Fig. 3 are fundamental diagrams of the present invention.

Fig. 4 is the structural representation of conveyance conduit.

The specific embodiment:

As shown in Figure 1-Figure 3, vertical axis type wind high pressure pump 2 highly is that the high pressure of (cost is low, easy to maintenance, not wind-engaging to impact) its generation all can be stored in first in the holding vessel 4 about 10 meters, then is transported to the river bed through steel pipe 3.The pipe thickness of steel pipe 3 is the 7-10 millimeter, diameter 100 millimeter.The place that facings the wind of 1 two sides abutment in the river course, every interval 1km installs vertical axis type wind high pressure pump 2 and produces gases at high pressure, and then utilizes gases at high pressure steel pipe 3 to be transported to the river bed.The installing the position and should vertically sink to the river bed along the main flow direction in river course of steel pipe 3, the optimum position is on main stem 6.

As shown in Figure 4: conveyance conduit is the super thick shape tube that increases the weight of, and has pore 5 on it, and the thickest part is 10 millimeters, and the thinnest part is 7 millimeters.Thick part is lower, and thin part is upper.
