Description
Technical field
The present invention relates to water conservancy and hydropower flood discharge technical field, more specifically non-close is without pump drainage cushion pool structure.
Background technology
With the construction of the regional large water conservancy hydroelectric engineering of Southwestern China, the engineering such as " high water head, big flow, narrow river valley " is special
Point is than more prominent, and flood-discharge energy-dissipating is the emphasis studied in engineering safely.In existing induced joint engineering Design of Discharge Dissipation, almost
The flood-discharge energy-dissipating mode that dam body chooses down stream is all employed, this Energy Dissipation Modes have simple engineering structure, short time limit and to letting out
The features such as flow, Tailwater Depth change strong adaptability.Because induced joint engineering flood discharge power is huge, how release floodwatering flow pair is avoided
Downstream river course causes seriously to wash away, and it is the research emphasis in engineering design safely to ensure flood discharge.With China's induced joint engineering
Build, the research of technique arrived by " the Seventh Five-Year Plan " between " 95 ", in existing induced joint engineering, choose down stream flood-discharge energy-dissipating mode and exist
Downstream sets the artificial concrete cushion pool of comprehensive lining cutting to carry out energy dissipating.
According to the achievement in research to flow-shape in cushion pool, it is rendered as after the water inflow water in cushion pool obvious oblique
Flood impact jet flow fluidised form, and form in cushion pool water cushion submerged hydraulic jump, thus its basic fluidal texture be jet main flow area+
The mixed structure of vortex region.The juncture area of wherein main flow area and each macroscopical vortex region is the strong turbulent fluctuation shear action area of a floor, main
Liu Gai areas make its effective mechanical energy (kinetic energy) constantly be disappeared to stop, so as to reach disappear by strong turbulent fluctuation shearing and diffusion
Can effect.Due to the turbulent fluctuation effect that water body in cushion pool is strong, larger fluctuation pressure is produced to cushion pool abutment wall and bottom plate, from
And influence the stability of abutment wall and bottom plate.In order to avoid turbulent water enters the larger uplift force of wall back of the body generation in cushion pool, simultaneously
In order to reduce the structural shape that cushion pool behind uplift pressure, existing induced joint engineering dam uses closing pump drainage：In concrete plate
Between structural joint in sealing is set, drainage pipeline networks and collector drain are set at the plate back side, back side infiltration is passed through into drainpipe
Net is imported in collector drain, and is further pooled in sump, is discharged by water pump.Close the side of pump-drainage type cushion pool structure
Wall is from top to bottom all using enclosed construction, and water body is completely separated in abutment wall back side seepage field and cushion pool, and wall backwater position is low
And fluctuation pressure is substantially not present, therefore the stable loading condition of influence abutment wall is clearer and more definite, abutment wall is stable not by dynamic hydraulic pressure in the pool
Power and sudden drawdown influence, abutment wall stability are preferable.
But the sealing and drainage system for closing pump-drainage type cushion pool structure are complicated, need to continue pump drainage in the normal runtime, long
Phase operation maintenance, construction investment and operation cost are larger, and there is the abutment wall mistake that destroyed stop-water or drainage system failure are caused
The security risk surely destroyed.
In recent years, with the construction of Southwestern China area concrete induced joint, dam site deep covering layer and deep water pad turn into
One important feature of flood-discharge energy-dissipating Building Design, therefore the natural water cushion energy dissipating in river course can be made full use of, so that simple
Change cushion pool protection Design to be possibly realized, such as using the cushion pool scheme of shore protection not river bottom protection.The cushion pool scheme bottom is without coagulation
Native lining cutting, if still using the structural shape of closing pump drainage, to prevent in cushion pool water body by bottom around oozing to the abutment wall back side,
Need to set seepage proof curtain in abutment wall bottom, increase difficulty of construction and construction investment, and reliability is difficult to ensure that.Meanwhile, by
High steep in the side slope of Narrow Valleys, concrete sidewall height in cushion pool both sides is higher, and the sealing and drainage system of abutment wall are more multiple
It is miscellaneous, there is destroyed stop-water and drainage system failure causes the risk of local abutment wall unstability, difficulty is big if drainage system blocks maintenance.
Closing pump-drainage type structure need to continue pump drainage in the normal runtime, and longtime running safeguards that operation cost is higher.If one kind can be proposed
Non-enclosed cushion pool structure, while cancelling pump drainage, then can greatly simplify cushion pool structure design, reduce difficulty of construction, drop
Low construction risk, and operation cost can be reduced.
The content of the invention

The present invention includes following advantage：1st, bottom discharge gallery, and base impervious curtain and draining curtain are eliminated, is eliminated
Evacuation system is closed, difficulty of construction is substantially reduced.
2nd, during normal runtime and maintenance, the infiltration of cushion pool massif and the wall back of the body is mainly discharged by osculum, no
Pump drainage must be carried out, operational management is convenient.
3rd, the height of abutment wall enclosed area is reduced, destroyed stop-water and drainage system failure cause the risk of local abutment wall unstability
Also it is smaller.
4th, the abutment wall surface drainage mouthful of closing portion can combine side slope packway arrangement, and can be according to the draining feelings of discharge outlet
Condition judges that wall carries on the back drainage pipeline networks operation conditions, checks directly perceived, operation maintenance relatively convenient.
5th, anchoring engineering amount of the non-close without pump drainage cushion pool structural shape is larger, but seepage control engineering, side wall concrete, only
The quantities such as water, drainage pipeline networks, pump drainage water system are substantially reduced.By taking black East Germany's engineering as an example, relative to closing pump-drainage type water cushion
Side of a pond wall scheme, does not consider to cancel the operation and maintenance cost of pump drainage, can save engineering direct investment about 30,000,000.
