Description
Technical field:
The present invention relates to hydraulic engineering technical field, in particular to a kind of river regulation method.
Background technique:
The SEA LEVEL VARIATION of Reservoir Tail falling zone will affect navigation, and the silt 70~90% into reservoir is to be disappeared to fall by library tail
Area enters reservoir, solves both of these problems and plays an important role and meaning, the prior art using plant-nursing riverbank area and
River training method extend the depth of water, due to library tail riverbed be water flow slow down, it is shifting, be easy siltation feature, the side of dredging
Method cannot thoroughly eliminate influence of the SEA LEVEL VARIATION to navigation, can not prevent library tail silt completely and enter reservoir area, therefore library tail river
Road, which is administered, becomes world-class problem.
Summary of the invention:
The present invention is a kind of Waterway Regulation of library tail falling zone, and the technical problem to be solved by the present invention is to thoroughly solve library
The world-class problem of tail river regulation.The technical scheme is that
When reservoir normal high water level (N.H.W.L.), the position that the maximum ship P Passable of reservoir area navigation reaches library tail is known as the navigation of library tail
Upper end；When reservoir normal low water level (N.L.W.L.), the position that the maximum ship P Passable of reservoir area navigation reaches library tail is known as under the navigation of library tail
End；The return water point of reservoir normal low water level (N.L.W.L.) is called falling zone lower end；In library, deep water hole, deep water are built in the position of tail navigation upper end
Hole is that effect is precipitating sandstone, and sandstone conveyer belt is installed in the bottom in deep water hole, and sandstone conveyer belt whole year ceaselessly works, according to not
The speed of service of how much adjusting sandstone conveyer belts of same time sandstone amount；The collective effect of deep water hole and sandstone conveyer belt is complete
Prevent library tailings stone and enters reservoir area；
Water level is built between falling zone lower end to library tail navigation lower end and keeps dam, and it is falling zone that water level, which keeps the effect on dam,
Navigation channel whole year keeps normal high water level (N.H.W.L.)；The backwater gate that water level keeps dam all in reservoir normal high water level (N.H.W.L.) is fully open
, just closing part backwater gate when the water level of reservoir is lower than normal high water level (N.H.W.L.) makes falling zone navigation channel keep normal high water level (N.H.W.L.)；
If falling zone navigation channel bank has large size city or falling zone to belong to important navigation channel, it is therefore necessary to which falling zone navigation channel whole year is protected
Water holding library normal high water level (N.H.W.L.) has particularly important function and significance to navigation economic development；
Deep water, which is cheated to water level, keeps the river between dam to be known as falling zone navigation channel；There is 3~4 months time to disappear among 1 year
Settle in an area navigation channel influenced because of water level decreasing Navigation capacity decline, the method to settle the matter once and for all be falling zone navigation channel whole year protect
Water holding library normal high water level (N.H.W.L.)；Water level keeps the river between dam to library tail navigation lower end expand deeply, and the river is made to have navigation
The deep water fairway of large ship.
In the above technical solution, deep water pit sand stone conveyer belt technology and falling zone navigation channel whole year keep the normal Gao Shui of reservoir
Position, the combination of two kinds of technologies could have special technical effect, if such as the river of sandstone conveyer belt position be not able to maintain one
The water level of depthkeeping degree, serious obstruction navigation accident can occur for the deep water hole of sandstone conveyer belt during low water；Sandstone conveyer belt
The advantages of cheating two kinds of technologies cooperations with deep water is, since deep water hole will be lower than 3~5 meters of riverbed bottom, so to the sandstone of flowing
There is precipitating, is deposited in sandstone on sandstone conveyer belt；
The water level in falling zone navigation channel is fixed, therefore the storage capacity in falling zone navigation channel is changed into non-storage capacity, due to existing
Reservoir it is more and more, most of reservoir, which becomes combining, controls flood, to flood control require declined, therefore storage capacity reduce
A part is filled perhaps；Water level keeps dam to be built in the updrift side position of library tail navigation lower end, rather than is built in library tail and leads to
The position of boat lower end, it is therefore an objective to occupy storage capacity less as far as possible；
Water level is built in the centre of reservoir and keeps dam, can be hindered fish migration, cutting river biological chain, be hindered ship current
Influence be very little；Water level keeps dam to be different from conventional reservoir dam, and 8~9 months water levels keep the gear on dam in 1 year
Sluice gate is fully open, and water level keeps dam not play any effect, and keeping dam to block 3~4 middle of the month of water in water level is also not continuous
Block water, be that discontinuity blocks water, therefore counter productive is smaller；And beneficial effect is then extremely huge, such as Sanmenxia Reservoir, moderate seas
Silt entrance is greatly decreased after implementing the technical program in bottom water library, Three Gorges Reservoir and other reservoirs for having library tail silt to enter
Reservoir, to substantially extend the service life of reservoir.
