Step 1, tunnel cofferdam 3 is carried out to construct, when construction pre-buried interim water inlet head 8；Carry out Diversion Tunnel Plug 201
Construction, before Diversion Tunnel Plug 201 is built up, after water is delivered to Diversion Tunnel Plug 201 by interim tapping pipe 802, and
Extend to downstream river course；
Step 2, it is built up in Diversion Tunnel Plug 201, plug built-in pipe 504 and ecological flow pipe plug back segment 505 of releasing
Afterwards, interim tapping pipe 802 connects plug built-in pipe 504, is released pipe plug back segment by plug built-in pipe 504 and ecological flow
505 release the water of upstream to downstream river course；
Step 3, after the completion of ecological flow releases the construction of pipe plug leading portion 503, interim tapping pipe 802 is connected to ecological flow
It releases pipe plug leading portion 503, is released pipe plug leading portion 503, plug built-in pipe 504 and ecological flow bleeder pipe by ecological flow
505 letdown flow of plug back segment；
Step 4, after Diversion Tunnel Plug 201 is constructed, tunnel cofferdam 3 is removed, and power station starts first filling, in this phase
Between, the water of reservoir area is evacuated to by permanent water inlet 401 by floating water plug 11, is downstream let out by ecological flow bleeder pipe 5
Put ecological flow.
When tunnel cofferdam 3 is constructed, first cofferdam built-in pipe 801 is embedded under tunnel cofferdam 3 when tunnel cofferdam 3 is constructed
Side, downstream flanks interim tapping pipe 802.Ecological flow of the interim water inlet head 8 for during 2 plugging construction of diversion tunnel is let out
It puts, when Diversion Tunnel Plug 201 is constructed, the water of upstream is connected to by diversion tunnel 2 by interim tapping pipe 802, in water conservancy diversion
Before tunnel plug 201 is built up, after water is delivered to Diversion Tunnel Plug 201 by interim tapping pipe 802, and downstream river is extended to
Road.
It releases after pipe plug back segment 505 builds up, passes through in Diversion Tunnel Plug 201, plug built-in pipe 504 and ecological flow
Plug built-in pipe 504 and ecological flow pipe plug back segment 505 of releasing release the water of upstream to downstream river course.
After the completion of ecological flow releases the construction of pipe plug leading portion 503, interim tapping pipe 802 is connected to ecological flow bleeder pipe
Plug leading portion 503 is released after pipe plug by release pipe plug leading portion 503, plug built-in pipe 504 and ecological flow of ecological flow
505 letdown flows of section.
After Diversion Tunnel Plug 201 is constructed, tunnel cofferdam 3 is removed, and power station starts first filling, during this period, is led to
It crosses floating water plug 11 and the water of reservoir area is evacuated to permanent water inlet 401, pass through ecological flow bleeder pipe 5 bleed downstream ecology
Flow.
When tunnel cofferdam 3 is removed, the interim head 8 that intakes is also synchronous to be removed, interim tapping pipe 802 and ecological flow bleeder pipe
The former interface of plug leading portion 503 is blocked using steel plug, is avoided in the dismounting of tunnel cofferdam 3 and reservoir operational process by mud
Sand is blocked, and influences to let out under ecological flow.
Floating water plug drops while water level lifting in upstream diversion tunnel cofferdam demolition and use when starting water storage
Low pumping head reduces power consumption.When enabling the device, vertical anchoring rope 1106 and anchor disk 1107 need to be put into reservoir bottom
Portion, makes anchor disk 1107 be always positioned at reservoir bottom, and anchoring rope 1106 is guided bank by the other end after anchoring pulley 1108, is used for
Fix the device.When water level rises, floating drum 1105 and the anchoring pulley 1108 being installed on floating drum 1105, immersible pump 1101 etc.
It can be gradually increasing with water level, and the anchored end gradually to bank is close, pull anchoring rope 1106 in due course, make anchor disk 1107
Be detached from bottom storehouse, be sunken to bottom storehouse again after it is apart from bank suitable distance for anchoring floating drum 1105, until water storage to permanently into
The mouth of a river above 0.5m of 401 elevation or so.Immersible pump 1101 starts after tunnel cofferdam 3 is removed, and water is evacuated to temporary storage tank
1103,1103 bottom level of temporary storage tank is higher than permanent 401 absolute altitude 0.5m of water inlet or so, and when normal use opens interim storage
Cistern valve 1112, and (floating water plug wouldn't be installed and vertically be blocked before deactivating by delivery hose 1104 and permanent water inlet 401
Dirty grid 402 and water inlet roof of mouth 403) sealing is kept, set the floating ball 1109 and matched floating ball in temporary storage tank 1103
Liquid-level switch 1110, when the water level in temporary storage tank 1103 is reduced to 30cm or so, setting floating-ball level switch 1110 is closed
It closes, is drawn water by water pump cable 1111 for electrically activating immersible pump 1101, library water is evacuated to by temporary storage tank by suction hose 31
1103, and when drawing water to away from 1103 peak level of temporary storage tank (no more than the elevation of the end nozzle of suction hose 1102, one
As for away from top about 20cm), setting floating-ball level switch 28 disconnects, and immersible pump 1101 stops pumping, and letdown flow is by ecological flow
The automatic flow control valve 6 of amount 5 end of bleeder pipe is controlled, and by 701 ecological flow digital monitors；702 ecological flows
Amount video monitoring apparatus is monitored.In water storage to the above 0.5m of permanent water inlet or so, delivery hose 1104 and permanent water inlet
Mouth 401 disconnects, and the letdown flow of permanent water inlet 401 comes from reservoir area water body, while installing vertical trash rack 402 and water inlet top
Lid 403 removes floating water plug 11.
