Technical field

The utility model is related to sediment control engineering device technique field, more particularly to a kind of dress of harnessing silted Yellow River alluvial Put.

Background technology

The Yellow River is of long standing and well established, since the dawn of human civilization, overflows frequently, though administering through thousands of years it is impossible to except suffering from, have its source in Huang River carries a large amount of silts through loess plateau, is unequal to rushing more, thus accretion and fill in resistance, certainly overflow frequent.Though now have " blocking ", The general plan such as " row ", " putting ", " tune ", " digging ", can not effect a radical cure, the Yellow River day is grand eventually, gradually have the gesture of acceleration, and North China Plain flood is not removed, It is suffered from more so.The method finding a kind of holding the Yellow River stream lasting stability is into the task of top priority.

The problem of the Yellow River, in fact can also regard as the Yellow River must through the length and breadth of land loess plateau problem.Scientific research shows Show, the feature in loess plateau is that loess is deep, distribution is vast, and loess mostly is eluvium, and particle is tiny, and quality is loose, has wet Sunken property.The surface runoff in loess plateau is many to be occurred with mountain torrents form, and water level rises suddenly and sharply and breaks.It is high that the above feature determines loess Former most area precipitation necessarily comes cruelly to rush in rainy season cruelly, and effect in administering yellow mud sand for the water-and-soil conservation measures is limited 's.Since it is inevitable that the silt in loess plateau enters river, and measure again huge, the Yellow River will be effected a radical cure, the silt row of korneforos To going in the sea greatly just to become inevitable, because only that there just admitting so many silt, carrying is got up also more economical, just Prompt.

The Yellow River is not the fluid of simple water already, and because the sediment charge ratio world is rare, she is huge more like one Loess handling system.The Yellow River mean flow rate flow of many years is relatively stable, in the case that there is not big change on riverbank, river Husky efficiency of averagely taking be also certain, the always husky amount that year is averagely washed away into sea by water is also basicly stable.Current can be taken Sand enters sea, is the potential energy that make use of water.See it is to cause because inflow-rate of water turbine is little, it is not enough to take husky efficiency in the Sediment Siltation form of expression Silt on long space-time downstream fltting speed is less than to river bed deposit speed, cause channel aggradation lifting, its reason essence On be：Under nature and long space-time, river takes that husky efficiency is basicly stable, what river contained take husky enter sea needed for gross energy Not enough.

The realistic problem existing for the Yellow River, solution one is to reduce into river sand amount, and two are to increase the gross energy of the Yellow River, Three is to improve flowing water to take husky efficiency.
