Description
The present invention relates to a kind of method of river channel sand-flushing desilting.
The Yellow River downstream sediment alluvial is serious, and the river course exceeds two sides and formed " canal on embankment " that is easy to take place big flood.In order to address this problem, people have proposed several different methods, and these methods roughly can be divided into two classes.One class is the energy that relies on river self to flow, and carries out channel sand-flushing desilting by some devices, and another kind of then is to rely on external energy and device declogging.For example, " high responsive formula is stired and make muddy device automatically " that Chinese utility application is introduced for No. 98229550.2 belongs to first kind method, and Chinese invention patent application No. 97108191.3 disclosed " underwater plough in river course " then belongs to second method.Because downstream, the Yellow River river surface is broad, discharge is little, stream plays pendulum, and main is also usually to stop, so utilize the first kind method of flow energy sand surfing obstructed in the Yellow River downstream.Second class methods need underwater operation usually, and task difficulty is big, also can only use under the bigger situation of discharge simultaneously, also are not suitable for the Yellow River downstream row and become silted up.Therefore, in order to solve " canal on embankment " problem in downstream, the Yellow River, be necessary to provide a kind of new effective ways.
The purpose of this invention is to provide a kind of method that is specially adapted to the river channel sand-flushing desilting in downstream, the Yellow River.
Method of the present invention is: the marine outfall, downstream near the effluent road riverbed in the river course center line has the sand surfing pipeline that sand surfing is chewed on the updrift side laying tube wall in river course, main water-delivery pump is set near the marine outfall in river course, appropriate location along the line is provided with auxiliary water-delivery pump in the river course, sand surfing on the described sand surfing pipeline is chewed on each pipeline section along the river that is arranged in the sand surfing pipeline, the upstream extremity sealing of sand surfing pipeline, the downstream of sand surfing pipeline is connected through main influent stream pipe with the head piece that goes out of described main water-delivery pump, this main influent stream pipe is provided with by-pass valve control, each pipeline section from the bottom to top of described sand surfing pipeline is provided with auxiliary inflow port, the auxiliary

influent stream pipe.The operating principle of the inventive method is: when the few water in river course or stop when anhydrous, utilize main water-delivery pump suction seawater and import the sand surfing pipeline by the downstream of sand surfing pipeline, the contrary river course of seawater that enters the sand surfing pipeline is up, in the up process of seawater, the seawater constantly sand surfing from each pipeline section of sand surfing pipeline is chewed ejection at a high speed, and near the riverbed the pipeline is washed away.Simultaneously, utilize river course auxiliary water-delivery pump suction fresh water or seawater along the line, flow to the sand surfing pipeline, give sand surfing pipeline feeder current and supercharging from the auxiliary inflow port of sand surfing pipeline.When high-velocity flow washed away near the riverbed the pipeline, current were being carried the silt that dashed secretly to dirty motion, and it is descending to drive adjacent riverbed sludge thus, formed billowing downward mud-rock flow.Like this, by washing away of a period of time, near the riverbed the sand surfing pipeline will significantly reduce and form a stable sprue, and interim season when many water, river will flow in this sprue that physical features is minimum in the riverbed.Simultaneously, become silted up if all adopt every year said method of the present invention to dash, the riverbed in downstream, the Yellow River will reduce year by year, finally becomes " subterranean stream " by " canal on embankment ", thereby fundamentally solving the flood problem of the Yellow River, benefits the descendants.In the present invention, the one way valve that is provided with on the auxiliary influent stream pipe can prevent auxiliary water-delivery pump during not to the sand surfing piped water supply current pour in down a chimney to auxiliary water-delivery pump by the sand surfing pipeline.In addition, the water source of auxiliary water-delivery pump both can be from the flowing water in the riverbed among the present invention, can also be from the pipeline of irrigation water.The packaged type influent stream pipe that utilization links to each other with the inflow port of auxiliary water-delivery pump can move the inflow port of this influent stream pipe the zone that water is arranged to the riverbed, the flowing water in the suction riverbed.When the flowing water in the inconvenience suction riverbed, then the inflow port of packaged type influent stream pipe can be connected with the irrigation water pipeline.Herein, said irrigation water pipeline can be the existing pipeline of laying on the riverbank.Certainly, in the present invention, also be recommended in and set up the irrigation conduit of laying from upstream to the downstream in river course on the embankment in river course specially, the upstream arrival end of the irrigation conduit of being set up is positioned at the river course, and irrigation conduit is provided with the head piece that can be connected with described packaged type influent stream pipe.Like this, the current in the upper river just can enter from the upstream arrival end of irrigation conduit and the downstream conveying.Water intaking is in the sand surfing pipeline when feeder current and supercharging in the irrigation conduit when needs, and the head piece that goes out that is provided with on the packaged type influent stream pipe that only needs to assist water-delivery pump and the irrigation conduit links to each other and gets final product.Simultaneously, the irrigation conduit of setting up can also solve the diversion irrigation problem of two sides, downstream, allow the two sides, downstream not the reason riverbed continuous reduction and cause diversion irrigation difficulty (riverbed after the water intaking end of original irrigating facility may incompatible reduce).In addition, for ease of in the river course, laying above-mentioned sand surfing pipeline, the present invention's suggestion few water or construct when anhydrous in the river course.In the present invention, main water-delivery pump can be provided with one or more, and is corresponding with it, and the main influent stream pipe that main water-delivery pump is linked to each other with the downstream of sand surfing pipeline can also be one or more.
Compare with class methods with aforementioned having now, river channel sand-flushing desilting method of the present invention is suitable for using in the downstream, the Yellow River that often is in disconnection state especially, and be convenient to implement, usually need not diving operation, by main water-delivery pump suction seawater channel sand-flushing desilting, can limit the river stream in the river course, thereby solve " canal on embankment " problem in downstream, the Yellow River effectively, benefit the descendants.
