Description
Technical field
The present invention relates to Construction for Hydroelectric Project diversion technology fields, and in particular to a kind of diversion tunnel hole plug energy dissipating knot
Structure and its method for arranging.
Background technique
Diversion tunnel reconstruction be gates of segmental shape control ecological drainage tunnel can meet the lock water storage phase under diversion tunnel do not stop,
Big flow discharges water, maintains river ecological, reduces the problems such as diversion tunnel gate water blocking water pressure, while solving and dam body is avoided to set
Dam body bottom diversion outlet existing for bottom diversion outlet is set to arrange that difficulty is big, complicate dam structure, influence the engineering straight line duration, use
The problems such as time is short, construction investment is big.
The ecological drainage tunnel of reconstruction can replace dam body bottom diversion outlet function, but run water for reconstructing ecological drainage tunnel maximum
Higher engineering under high water head service condition, will be formed in ecological drainage tunnel downstream side original diversion tunnel barrel section and outlet
High-velocity flow will make ecological drainage tunnel downstream side original diversion tunnel barrel section and outlet if not taking suitable energy dissipation measure
At erosion damage, to influence ecological drainage tunnel operational safety.For ecological drainage tunnel downstream side original diversion tunnel, there are curved segments
Engineering, high-velocity flow passes through curved segment in hole, it is also possible to cause erosion damage to diversion tunnel.
In this regard, to guarantee to reconstruct operational safety of ecological drainage tunnel under the conditions of high water head ecological drainage tunnel need to be being reconstructed
The interior suitable energy dissipater of arrangement.
Cavern energy dissipator is to pass through the mutation or Other Engineering measure of flow section, artificial system inside water tunnel
The rotary roll for making big turbulent fluctuation makes the part energy of water flow be converted into thermal energy, so that reaching reduces water export energy, reduces energy dissipating
Building investment, the effect of optimization hydraulic structure arrangement.It is flood discharging tunnel that cavern energy dissipator, which is often arranged in diversion tunnel reconstruction,
In engineering, there are several types of stilling pond, orifice plate and hole plug, such as following tables in: stilling pool slab, spiral-flow type energy dissipater, hole for existing type
It is shown:
The reconstruction of built diversion tunnel is flood Discharge tunnel Project cavern energy dissipator statistical form both at home and abroad
Diversion tunnel reconstruction is flood Discharge tunnel Project, general using " dragon comes back " Reconstruction plan, flood discharging tunnel import and former water conservancy diversion
Tunnel export compare there are larger height difference have arrangement stilling pool slab, in spiral-flow type energy dissipater and hole stilling pond condition, but it is above-mentioned
Energy dissipater needs to excavate larger-size underground chamber, requires height to geological conditions, structure is complicated, and construction investment is big；Orifice-plate type
Energy dissipating construction is simple, and energy dissipation rate is high, but cavitation easily occurs at orifice sharp-edged, and surface needs special material to protect, and hole
Water flow impact pressure suffered by plate self structure is big, and self structure stabilization is difficult to ensure, orifice plate outlet is easy to produce higher water wing, influences
Overcurrent safety；The plug energy dissipater bodily form and structure are simple, and only diversion tunnel reconstruction in Luding power station is flood Discharge tunnel Project at present
In used plug energy dissipater, but diversion tunnel reconstruction is in flood Discharge tunnel Project, and diversion tunnel outlet port is lower, exit
In floodage, hole plug position hydrostatic pressure is very big, need to reduce hole consent mouth and former diversion tunnel flow surface as far as possible
The ratio between product to improve energy dissipating efficiency, while guaranteeing there are enough positive pressures in the plug of hole, avoids that cavitation and cavitation erosion occurs.
And diversion tunnel reconstruction be gates of segmental shape control ecological drainage tunnel when, inlet and outlet height difference it is smaller, do not have arrangement
The ecological drainage tunnel upstream operating water level of the condition of stilling pond in stilling pool slab, spiral-flow type energy dissipater and hole, reconstruction is needed from water conservancy diversion
Tunnel floor elevation is run to mesoporous elevation, and operating water level luffing is big, and operating head polishing is high, and downstream is typically in free discharge shape
State, service condition is severe, and using orifice-plate type energy dissipater, energy dissipation rate and AND DEWATERING FOR ORIFICE STRUCTURE inherently safe are difficult to reach requirement；Currently, hole
Plug energy dissipater is used in pressure flow, and the service condition for being in free discharge for downstream there is no precedent.
