The structure composition of anti-filter wall from inside to outside is:The penetralia of anti-filter wall is pillar, and one is wrapped up in the outer surface of pillar
Layer has the strainer of certain plasticity, is the loaded filter of graded gravel in the outer layer of strainer.
Loaded filter is made of multi-layer with uniform and weather resistance sand, gravel, cobble or rubble.
Material requirements used in above-mentioned anti-filter wall is:Columnar stays structure should have enough intensity and durability degree to support
Load;The dead weight of anti-filter wall and water pressure can be supported and transferred to strainer and indeformable close to rigid structure;For loaded filter, every layer
Gravel grading is uniform, and grain size increases with seepage direction, and loaded filter should have enough sizes to adapt to possible inhomogeneous deformation.
In the present invention, the function of above-mentioned all parts is as follows:
There is enough height difference in upper river with downstream river course.On the one hand the water in upper river is enabled to pass through overfall dam
Dirt sand is brought in into downstream river course;On the other hand the dirt sand in flume can be made to drain into downstream river course by desilting pipeline.
The design of the radian of concave bank and convex bank can be designed according to landform, actual current, reach optimal design effect,
To reach saving material.
Meanwhile river is arranged to concave bank and convex bank, from hydrodynamics and the law of inertia, convex bank current are slower, make
A large amount of sediment depositions are deposited in the convex bank of key water control project, and concave bank current are very fast, and the sediment charge of concave bank is relatively low in river, flume
I.e. from the diversion of concave bank side.
The angle of flume and downstream river course and overfall dam should go to calculate according to Practical Project requirement, and 30 ° of angular range-
50°。
The plane height of flume is higher than upper river, effectively bed load sediment can be controlled to enter water-drawing channel.
The water inlet of flume will set trash rack.Prevent branch, spoil in upper river entrained by water etc.
Impurity enters flume.
Sand discharge lock is provided on overfall dam, and is provided with sand discharge hole.Part can be also played when sand discharge lock is not opened
The effect of sand discharge also can be that downstream ecology needs to provide part water source.
River almost horizontal before overfall dam, to accumulate drop.It, can be with when sedimentation amount reaches design sediment outflow amount
Starting gate washes away the sand setting of overfall dam upstream using the prop-carrying capacity in river itself.
The present invention sets overfall dam and another effect for having sand discharge lock to be that it is possible to ensure water diversion flow in dry season,
Simultaneously flooding action is played in the flood water phase.
Steel-slag sand is mounted on sand discharge lock.But steel-slag sand easily corrodes in environment, we use the moon of sacrificial anode
Pole Protection Code protects steel-slag sand.Spelter is arranged according to actual needs.
Stiling basin is provided with after overfall dam, it is placed over to have baffle wall style.By hydraulic jump, the torrent that discharge structure is released
It is changed into unhurried current, to eliminate the Energy Dissipation Modes of kinetic energy.The flowing water effectively reduced rapidly washes away downstream river course (2).
River wall is arranged to vertical pattern, improves the trapezium structure of traditional mode.The excavation in mountain area is reduced with after
Phase difficulty of construction.
River wall, the vertical mode of setting reduce stability, we are provided with (9) anchor pole inside it, to enhance
Its stability.
The effect of stiling basin of the present invention and function:By hydraulic jump, the torrent that discharge structure is released is changed into
Unhurried current, to eliminate the Energy Dissipation Modes of kinetic energy.Because its mainstream is located at gool bottom, therefore also known as energy dissipation by hydraulic jump.Energy dissipation by hydraulic jump mainly by
Strong turbulent fluctuation, shearing and blending effect between the surface roller of hydraulic jump generation and rotary roll and underflow.It has fluid stable, energy dissipating
The advantages that effect is preferable, adaptable to geological conditions and tail water luffing, and tail water fluctuation is small, and maintenance cost saves.Meanwhile stiling basin
On be provided with baffle wall style, the effect of energy dissipating is made to become more preferable.
Setting pot slows down the flow velocity of water using its width, so that the ability that flowing water carries silt is greatly reduced, silt
Setting pot bottom will be deposited on.Setting pot bottom is arranged to infundibulate, facilitates to form vortex, in order to sediment outflow.
When sand setting amount reaches a certain setting value, sediment outflow gate and sand pump are opened, is vortexed in setting pot, sand setting quilt
Discharge.
The effect of water-drawing gate:Natural water is introduced into this water conservancy projects according to water diversion flow requirement.
The effect of stiling basin:The kinetic energy of natural water is eliminated, its flow velocity is reduced, facilitates follow-up sand discharge process.
The effect of trash rack:Prevent natural water surface floating material (branch, dead wood, production and living rubbish etc.) into originally
Water conservancy projects.
Sand discharging pump, in the present invention, each sand discharging pump are connected to two sediment outflow pipelines, usually only use wherein one, separately
A piece conduct is spare.Control cost can so be greatlyd save.The sand discharging pump and sediment outflow gate of sediment outflow are all positioned in underground gallery
It is interior, facilitate the maintenance of staff.
Most silt is discharged into downstream river course to pipeline at last, pipeline exposure river wall, this be in order to prevent silt in river side bank
Bulk deposition interferes river normal operation.
Anti-filter wall:Graded gravel from fine to coarse is subject to strainer and columnar stays structure.Graded gravel requirement any layer
Particle does not allow the hole through adjacent thicker one layer.The particle of same layer can not generate relative movement.Strainer use compared with
The material of high intensity, shape and position to fixed graded gravel.Columnar stays structure, that is, pile is for ensuring that anti-filter wall
Position and the required structure of stability, but it is noted that must not influence current normal through or cause larger whirlpool.
When current by when, the sieve of graded gravel picture from level to level has blocked the different silt of particle size, and current then may be used
With normal through.The silt that anti-filter wall upstream is blocked can be discharged to channel (river) by measures such as scouring sluice, sand pumps.
Channel wall can be arranged to vertical in form by the present invention in view of mountain construction is more difficult, to reduce excavated volume.It is but vertical
Be unfavorable for enhancing its stability, therefore we set anchor pole on river wall, make its it is firm be fixed on ground, ensure its energy
Bear corresponding pressure.
The present invention cannot make overall plans for existing key water control project, i.e., diversion while cannot be guaranteed downstream ecology demand;
Withered, the news water phase cannot effectively be controlled to reach diversion requirement and ensure building safety.Provide a preferable settling mode.
The present invention has the characteristics that compared with existing key water control project:
The present invention key water control project so that the flowing water of upstream high sediment concentration can reduction of speed desilting, reduce sediment charge.Upper strata
Clear water enters water-drawing channel, to prevent bed load sediment from entering water-drawing channel, the datum line of flume is taken to be higher than river ground
To a certain degree, while trash rack is set to prevent sundries from entering flume.
Tract disposes overfall dam, can be while water diversion flow is ensured in dry season, in flood water phase flood control and disaster reduction.Horizontal river
The drop of road accumulation, improves water diversion, can wash away upstream shoal materials by current sand carrying capacity when the guillotine door was open.
Meanwhile the present invention can effectively be lowered into the sediment charge of flume, and the no longer manually method of dredging
Handle the desilting of upstream.
