Description
Technical field
The invention belongs to the acquisition of reservoir deposits and process fields, and in particular to a kind of box feed ditch sand discharge dress of small reservoir
It sets.
Background technique
There is sediment siltation in some small reservoirs, will occupy part storage capacity after sediment siltation, and influence reservoir
The flood control safety of flooding action and dam itself to downstream, since siltation loses storage capacity constantly, causes reservoir anti-in reservoir area
It is flooded to irrigate, generate electricity and the effect of ecological water transfer performance is restricted greatly, influence the normal utilization of dam safety evaluation performance and building, dam
Preceding building includes ship lock, approach channel, hydroturbine water intake mouth, channel irrigating gate etc., Sedimentation Problems all occurs, coarse sediment into
People's hydraulic turbine can cause to wear, and water plant enters trash rack it will cause blocking, reservoir head retrogressive deposition, increase upstream flood with
It loses, silt content reduction is let out in siltation in library under making, and is washed away over long distances so as to cause downstream river course, is gradually decreased water level, downstream
River-bed deformation.
The sand discharge desilting mode of reservoir mainly has the clear beach volleyball of waterpower to become silted up both at home and abroad at present and mechanical row is become silted up, waterpower sand discharge dredging
It is the characteristics of motion according to water flow, the characteristics of the sediment carrying capacity having using water flow, according to the wish of people, passes through waterwork
Object is discharged to the silt of reservoir area in specified region to reach and wash away riverbed, expand section, reduce beach siltation and expand storage capacity
Purpose.The method of reservoir sand discharge dredging has at present: flood detention sand discharge leads the modes such as density current sand discharge, emptying sand discharge and lumped scour.
Leading density current sand discharge is that can generate when reservoir is in flood storage and lead density current phenomenon, can be arranged as far as possible using leading density current
Sand, the starting gate when leading density current and reaching before dam, a large amount of silts that can carry flood secretly are discharged outside library, reduce reservoir sedimentation.Cause
After slipping into clear water for muddy water, some muddy water is spread into clear water, especially slips into the silt near a little in major trough two sides
Silt is largely fallen on beach, thus it is lower than flood detention sand discharge power to lead density current sand-flash effect.Leading density current sand discharge is reservoir in water storage
Sand drained measure.Northern China arid and semi-arid regions, water lack, and reservoir sand discharge is suitable with the contradiction of water storage Xing Li
Prominent, the reservoir in these places is small because leading density current sand discharge abandoning water, does not influence reservoir filling, and can be in conjunction with irrigation, thus obtains
Extensive attention and utilization, lead density current sand discharge and do not need emptying storage capacity, do not influence reservoir filling, tool has an enormous advantage.
Especially nervous for those water sources, the area of anhydrous sand discharge should not but use, therefore have to using mechanical dredging.
Mechanical dredging as the sand discharge energy and utilizes external energy method two major classes including the use of reservoir water source.The former utilizes reservoir upstream and downstream
Sediment before building is drained outbound with floating hose according to siphon principle by water-head.The latter's dredger or slush pump etc.
Mechanical dredging is suitable only for the especially valuable reservoir of water resource.Main method has: siphon dredging, air-powered pump dredging and dredger
Dredging.
For Reservoir-irrigated District, row is let out in conjunction with irrigated area crop water and reservoir, introduces the water into Irrigation Project Design crop or silt
Ground is built up fields, and soil fertility can be improved, and promotes agricultural production and income.Draw the rational allocation that big vast warping needs water, also to master is closed
The warping quota of reason, and science lays irrigation facility, in addition also needs actively to prevent and treat Liang Dao siltation, the approach generallyd use has: mentioning
High water velocity subtract it is husky fall silt, clear water draws and becomes silted up, clear muddy separates water delivery and muddy water Liang Dao for rationally designing conveying hyper-concentration flow etc..
108729421 A of patent of invention CN discloses a kind of for water conservancy diversion sand discharge apparatus before hydraulic structure, including water conservancy diversion
Wall, baffle, lifter plate and disturbance module；The disturbance module arrangement is connect between training wall and baffle, and with baffle, lifting
Plate can be risen and be landed by winch hoist, when lifter plate lands, be bonded with training wall and baffle, and disturbance module is fixed on gear
On plate, keep certain mistakes water distance from while disturbing module and being designed to three-dimensional two to pinch plane shape, increase water flow is disturbed with training wall
It is dynamic, it is more likely formed spiral flow, lifter plate ensure that the water flow of different flow directions can form spiral flow carrying by device and flow through,
Silt mud before removing hydraulic structure, to guarantee that hydraulic structure operates normally.
For the particularity of the sand discharge of small reservoir, silt is discharged, liberates storage capacity, while also collecting sand again
It utilizes, does not allow sand to silt lower reservoir up, blocking river is not one under the premise of protecting reservoir and river ecological environment
Part lead-pipe cinch needs the application of comprehensive multiple technologies.
