Description

Raise sand device of administering yellow river

Technical Field

The invention relates to the technical field of yellow river treatment, in particular to a sand raising device for treating a yellow river.

Background

The yellow river has long source flow and history, and is frequently flooded and disastrous, although the yellow river is treated for thousands of years, the yellow river can not remove the diseases, and the yellow river is mainly caused by that the yellow river flows through loess plateau to carry a large amount of silt which can not surpass the flushing, so that the yellow river is blocked due to accumulation, and the overflow frequency is still avoided. Although the Chinese herbs have the root cause of 'blocking', 'draining', 'releasing', 'regulating', 'digging' and the like, the yellow river diuron has the tendency of accelerating, and the flood is especially serious in North China plain. It is urgent to find a method for maintaining the flow path of the yellow river stable. The problem of the yellow river can be regarded as the problem of the loess plateau of the vast scale which the yellow river must pass. Scientific research shows that the loess plateau is characterized in that the loess is deep and widely distributed, most of the loess is aeolian materials, the particles are fine, the texture is loose, and the loess has collapsible property. The ground runoff of loess plateau appears in the form of mountain torrents mostly, and the water level rises and falls violently. The characteristics determine that rainfall in most regions of the loess plateau is always rushed in rainy season, and the effect of water and soil conservation measures in treating yellow sediment is limited. Since the silt of loess plateau can not be avoided entering the river and the amount is huge, the yellow river needs to be cured radically, the silt in the river is inevitably discharged into the sea, and the silt is more economical and convenient to carry because the silt is more contained only in the sea. The yellow river is not a pure water fluid for a long time, and is more like a huge loess carrying system because the silt content is rare in proportion to the world. Under the condition that the annual average flow velocity and the annual average flow rate of the yellow river are relatively stable and the river bank is not greatly changed, the average sand carrying efficiency of river water is also certain, and the annual average total sand amount flushed into the sea by water is basically stable. The water flow can carry sand into the sea, and the potential energy of water is utilized. The sediment accumulation is expressed by the fact that the sediment is pushed downwards at a lower speed than the sediment speed of the riverbed in a long time due to small overflow and insufficient sediment carrying efficiency, so that the riverbed sediment is lifted, and the reason is essentially that: under natural state and long-term space, the sand carrying efficiency of the river is basically stable, and the total energy required for carrying sand into the sea in the river is insufficient. Aiming at the practical problems existing in the yellow river, the solution is to reduce the sand entering the river, increase the total energy of the yellow river and improve the sand carrying efficiency of flowing water. At present, national strategies for governing yellow river are mainly 'blocking', 'discharging', 'releasing', 'adjusting' and 'digging'. The 'blocking' is to reduce the amount of sand entering the river as much as possible, and is mainly to keep water and soil and construct a dam bank in the middle and upstream of the yellow river; the 'discharging' and 'transferring' are the method of discharging sand into the sea by jointly transferring the sand by utilizing the inherent river channel, the large water flow in the flood season and the reservoir, and the method is a method for improving the sand discharging efficiency; the 'discharging' and 'digging' are the sand pumping and land making and the dredging of the river back, which are the supplement for reducing the sediment deposition at the downstream of the yellow river. From the practical situation, the measures cannot fundamentally solve the problem of long-term tendency of silt deposited on the riverbed at the downstream of the yellow river to rise. At present and later, the yellow river has the main characteristics that the sand can be efficiently discharged only by large water flow before and after the flood season, the flow rate in most of the time is small, the flow speed is slow, the riverbed sediment, particularly large-particle sediment, is difficult to start at the stage, and the sand conveying amount is small. And through the construction of a large-scale dam bank group at the middle and upper reaches of the yellow river, the yellow river can realize continuous flow all the year round, and the flow control of the yellow river in the non-flood season is better and more ideal along with the construction of a new dam bank. The improvement of the full-time and air sand transportation efficiency of the yellow river is imperative, and particularly the improvement of the sand discharge efficiency of the 'small water' stage of the yellow river has huge space.
