Abstract
A method for harnessing river includes such steps as building movable water collecting dam at upstream and channel protecting dam at downstream, positioning water-air jet ship generating jet between said two dam, pilotting the slurry to the shoals or beach land, where silt deposit is needed, moving both dams towards downstream by one unit and repeating said jobs. It can drege the river and make it straight with reduced engineering quantities.
Description
The present invention relates to a kind of method and special equipment thereof of river regulation
The Yellow River flood all effluent water sand content is high and cause that silt moves on to the downstream by middle reaches, the Yellow River thousands of miles away, wide, shallow, diffusing, random because of the river course, and current lose speed, and sand deposits at leisure; According to historical records, the downstream, the Yellow River is " turbid " river during the Qin, saying of " river being deep, number is a stone water and six bucket mud " is more arranged during the Western Han Dynastry, and form canal on embankment.After entering 21 century, downstream flood-prevention work done on rivers engineering specification improves, resisting the flood ability strengthens, but Sedimentation Problems is difficult to basic solution in quite over a long time, the aboveground river situation long-term existence of Xing Chenging in history, the main means of existing waterway regulation flood control are to increase dyke, the river course is but shallow day by day narrow, main stem is atrophy day by day, and the riverbed is outstanding more high more; The traditional theory of dredging waterway and method, emphasize very that all water-based can only dredge and lead, i.e. it " property " downstream, and led by rivers passively, the Yellow River flood has the advantages that to rise suddenly to fall suddenly, Sedimentation Problems is the very crux that the Yellow River is difficult to administer, and mainly takes at present: " blocking " mainly blocked by the water and soil conservation in area, upper and middle reaches and Heavenly Stems and Earthly Branches current control major project and subtracted silt, but can only reduce husky amount rather than sand is blocked fully in the upstream; " row " is exactly the construction by all kinds of flood-prevention work done on rivers engineerings, utilize existing river course to be conveyed into the sea with blocking silt incessantly, but have 2/3 to deposit after the outlet of actual silt approximately in the doorway district, mouth is prolonged outdoors, rather than all enter the deep-sea, mouth prolongs outdoors with causing the alluvial of tracing to the source, and raises the riverbed, strengthens the problem that capability of sediment outflow can not solve river course lasting alluvial lifting so strengthen the transportability of sediments in existing river course merely; " accent " and " putting " can partly solve the Sedimentation Problems in downstream, the Yellow River, but these two kinds of governance ways are subjected to the restriction of several factors; " digging " is exactly to dig the river silt back of the body, reinforces the Yellow River main dike, progressively form " relatively going to river ", but the rising embankment in riverbed must increase thereupon; Above-mentioned policy respectively has limitation, still can not fundamentally grasp the initiative that brings the Yellow River under control.
The object of the present invention is to provide a kind of method of utilizing the river regulation of current migration silt, degradation riverbed, handled easily, cost saving, the present invention also provides a kind of special equipment of realizing this method for this reason.
Silt in the Huanghe water is to move on to the downstream by thousands of miles away middle reaches, and current lose speed, and sedimentation is got off; These deposit the silt that gets off, if impact dashing of being produced through water jets under high pressure and high pressure air stream, cut, brush, wash in a pan, wash, squeeze, press, bump, vibration, friction, the large-area surperficial tension of air bubble, disperse with chat close trickle ripple after producing and the comprehensive function of the factors such as disturbance in shock wave and the uphill process, immediately broken cracking is dissolved, being transformed into suspended load is in the same place with reconfiguring than the bed load of fine particulate and with water, thereby obtain mobile, it is long-pending that suspended load is taken away the drift sludging that just can fall for a long time by current, the bed load of fine particle shape then moves a segment distance under flow action, the size of this distance is directly proportional with water velocity, be inversely proportional to the particle diameter of self, this just offers our available opportunity, since being river, brings in the mud of the Yellow River from So Far Away, because having changed, objective condition deposits, we can create conditions fully and utilize river that the mud that deposits is taken away again to So Far Away so, principle with water vapor jet, mud, clod changes suspended load and bed load again into, by the mobile inexhaustible huge energy that is had of Huanghe water self, the mud of the Yellow River downstream siltation, clod is pushed the river shoal, two sides of the Yellow River to, with the main stem degradation, curve cut-off, make hanging river revert to subterranean stream.
For achieving the above object, the method for a kind of river regulation of the present invention the steps include:
