Description
Technical field
The invention belongs to water conservancy and hydropower industry waterpower energy-dissipating tech field, particularly a kind of stiling basin inspection that can be reused
Repair device and repair method.
Background technology
In the control section downstream dissipator of energy work design of Hydraulic and Hydro-Power Engineering, stiling basin structure is extensively applied.Stiling basin receives water
, often there is structural failure situation in the adverse effects such as power is washed away, sand erosion.It is higher than stiling basin structure elevation shadow by the level of tail water
Ring, stiling basin maintenance obtains difficult in construction at dry land condition.According to underwater repair scheme, but because construction environment is poor, repair material
Material is more difficult, and very well the factor such as cementing causes repairing quality poor with original structure.
Stiling basin maintenance prior art mainly has three kinds：(1) using caisson (or heavy cabinet) service technique, the such as Bark of India
Draw the engineerings such as power station, China's Gezhouba Water Control Project.(2) using the high tail bank design of stiling basin, overhaul reduces in the level of tail water
Carry out during to tail bank elevation.This is often needed in the river withered phase, while limiting situation about generating electricity possesses maintenance condition, such as China
Xiangjiabahydropower project engineering.(3) Temporary Cofferdam measure, such as China Gong Zui, five Qiang Xi Hydropower Projects are built using downstream.
Caisson (or heavy cabinet) service technique is complicated, and construction risk is higher, long in time limit, and is not suitable for curved surface maintenance.Meeting
On the basis of deep water pad energy dissipating, the high tail bank scheme of stiling basin often causes tail bank structural style big.Particularly the normal low water level in downstream compared with
Gao Shi, not only construction investment is big for the high tail bank scheme of stiling basin, and waterpower goes out stream condition and is unsatisfactory for two sides requirement of shelter.Build in downstream
Temporary Cofferdam scheme, takes time and effort, and not reproducible utilization, economic serviceability is poor.
The content of the invention
It is an object of the present invention to provide a kind of stiling basin apparatus for examination and repair that can be reused and repair method.The present invention
Time saving and energy saving with repeatable utilization, maintenance is flexible, the characteristics of stiling basin maintenance condition obtains convenient and low cost.
Technical scheme：A kind of stiling basin apparatus for examination and repair that can be reused, including stiling basin tail bank, stiling basin
Tail bank is connected with concrete foundation, and concrete foundation is hinged with the side of movable water blocking door, and movable water blocking door lower section is provided with air cushion
Holding tank, is provided with air cushion in air cushion holding tank, air cushion Jing air cushion control pipers are connected with control room.
It is aforesaid can be in the stiling basin apparatus for examination and repair of recycling, the opposite side Jing locking bolts of described movable water blocking door
It is connected with concrete foundation.
It is aforesaid also to connect between described movable water blocking door and concrete foundation in the stiling basin apparatus for examination and repair of recycling
It is connected to security control band.
It is aforesaid can be in the stiling basin apparatus for examination and repair of recycling, height H and the downstream highest of described movable water blocking door
The discrepancy in elevation Δ H=H-H '=0.5m～1.0m of water level H ＇.
It is aforesaid can be in the stiling basin apparatus for examination and repair of recycling, the height of described concrete foundation top and stiling basin tail bank
Path difference h >=0.5m.
It is aforesaid can the repair method of stiling basin apparatus for examination and repair of recycling be：When the level of tail water≤downstream peak level
During H ＇, overhauled；Control room expands air cushion by the inflation of air cushion control piper, and movable water blocking door rotation is erected and both sides
Lead wall and form dash barrier, stiling basin maintenance is carried out by the water in stiling basin is drained.
Beneficial effect
Compared with prior art, the patent of the invention avoids build Temporary Cofferdam or high tail bank, and stiling basin when running
Stream is smooth, and construction investment is few, simple structure, low cost, has been well adapted for the engineering maintenance of downstream deep water pad.By air cushion
Control activity water blocking door can it is quick, convenient, repeat to obtain stiling basin downstream dash barrier, it is time saving and energy saving to obtain more for service work
The abundant duration ensures.And compared with high tail bank, the river withered phase is arrived without the need for waiting, its maintenance is more flexible.
