Mouth is slagged tap；
Step 3, is excavated and supporting diversion tunnel block section, diversion tunnel coarctation segment, connection diversion tunnel block section discharge water with ecology
Hole vertical shaft；
Step 4 after the completion of ecological drainage tunnel and Diversion Tunnel excavation, carries out concrete knot to ecological drainage tunnel and diversion tunnel
Ecological drainage tunnel work lock chamber is closed in structure lining cutting, opens diversion tunnel work lock chamber, and diversion tunnel carries out overcurrent, is then shut off water conservancy diversion
Hole work lock chamber, carries out lower lock water storage, and diversion tunnel completes construction diversion；
Step 5, after diversion tunnel block section and diversion tunnel coarctation segment consolidate and meet design strength requirement, according to construction
It needs to open ecological drainage tunnel work lock chamber, ecology is carried out to downstream and is discharged water.
When excavating ecological drainage tunnel in step 1, first there is pressure section entrance to build construction road in ecological drainage tunnel, and by
Entrance is downstream excavated.
In step 1 excavate diversion tunnel in inlet of diversion tunnel section when, need to according to by inlet of diversion tunnel section upstream inlet and
The mode that lower exit is excavated into hole respectively, which is excavated, slags tap, and before excavating diversion tunnel work lock chamber, working tunnel is first arranged,
Then it takes mode from top to bottom to excavate, is slagged tap by working tunnel.
The knot that a kind of application for the structure that diversion tunnel and ecological drainage tunnel combine, the diversion tunnel and ecological drainage tunnel combine
Structure is suitable for the diversion tunnel of middle and high head and the combination arrangement of ecological drainage tunnel.
The utility model has the beneficial effects that the structure that this diversion tunnel provided by the utility model and ecological drainage tunnel combine
And its construction method and application, compared with the existing mode that ecological drainage tunnel is separately provided, the utility model solve due to
Diversion tunnel and ecological drainage tunnel it is arranged apart and the problem of increase project amount, construction investment and construction period, pass through two buildings
The layout pattern that object combines meets construction diversion and the ecological requirement to discharge water, reduces project amount, reduces engineering throwing
Money, shortens the duration；With existing diversion tunnel compared with the structure of " dragon comes back " pattern that flood discharging tunnel combines, solves " dragon lift
The problems such as energy dissipating is difficult under the conditions of head " the common high-velocity flow cavitation erosion of pattern, high water head, the life suitable for middle and high head
