Description
Technical field
The invention belongs to the water conservancy project technical fields in hydraulic and hydroelectric engineering, and in particular to a kind of diversion tunnel and ecological drainage tunnel
In conjunction with structure and its construction method and application.
Background technology
As country is to the pay attention to day by day of environmental issue, in hydraulic and hydroelectric engineering construction, environmental protection administration can all require list
Only ecological drainage tunnel of setting, to let out ecological flow under downstream, it is ensured that constructing with operational process middle and lower reaches natural river course not in power station
It stops.In response to environmental protection administration, currently, the way of ecological drainage tunnel routine is that ecology is separately provided to discharge water
Hole, and other buildings arrange that operation is independent of each other independently of each other.Although this conventional way can meet the need of engineering
It wants, but will increase construction investment, extend the duration.For diversion tunnel as a temporay building, main task is construction diversion, degree
Flood, after major project completion, lower lock water storage, and blocked, that is, its task is completed, and do not use.
Invention content
The structure and its construction method that are combined the object of the present invention is to provide a kind of diversion tunnel and ecological drainage tunnel and application,
Existing ecological drainage tunnel and diversion tunnel is overcome individually to be arranged, caused investment problem big, long in time limit.
For this purpose, the present invention provides the structure that a kind of diversion tunnel and ecological drainage tunnel combine, including ecological drainage tunnel and lead
Flow hole, the ecology drainage tunnel and diversion tunnel are laid up and down, the downstream of ecological drainage tunnel by ecological drainage tunnel vertical shaft with lead
Flow hole connection.
The ecology drainage tunnel from upstream to downstream successively by ecological drainage tunnel have pressure section, ecological drainage tunnel work lock chamber,
Ecological drainage tunnel passes through ecology without pressure section connection composition, ecological drainage tunnel without pressure section downstream and ecological drainage tunnel vertical shaft upstream end
Drainage tunnel eddy flow volute chamber is connected to.
The diversion tunnel is from upstream to downstream successively by inlet of diversion tunnel section, diversion tunnel work lock chamber, diversion tunnel block section

The diversion tunnel block section is equipped with diversion tunnel coarctation segment, diversion tunnel contracting with ecological drainage tunnel vertical shaft connectivity part tract
Narrow section is connected to diversion tunnel block section, and the cross dimensions of diversion tunnel coarctation segment is less than the cross dimensions of diversion tunnel block section.
For gateway opening shape, ecological drainage tunnel has pressure section to be put with ecology without section cross section is pressed for the diversion tunnel and ecological drainage tunnel
Water hole vertical shaft cross section is circle.
A kind of construction method for the structure that diversion tunnel and ecological drainage tunnel combine, includes the following steps：
Step 1, is first excavated and supporting inlet of diversion tunnel section and diversion tunnel work lock chamber, then carry out ecological drainage tunnel have pressure section,
Ecological drainage tunnel work lock chamber, excavation and first liner timbering of the ecological drainage tunnel without pressure section, ecological drainage tunnel eddy flow volute chamber；
Step 2 excavates ecological drainage tunnel vertical shaft by the way of from top to bottom, is connected to ecological drainage tunnel vertical shaft and discharges water with ecology
When excavation, lifting appliance is arranged on ecological drainage tunnel vertical shaft top for hole eddy flow volute chamber, and arrangement backhoe grab bucket on lifting appliance will
The slag charge of excavation is promoted to ecological drainage tunnel vertical shaft top, and direct discharging to dump truck is gone out by ecological drainage tunnel vertical shaft import
Slag；
Step 3, is excavated and supporting diversion tunnel block section, diversion tunnel coarctation segment, connection diversion tunnel block section and ecological drainage tunnel are perpendicular
Well；
After the completion of ecological drainage tunnel and Diversion Tunnel excavation, concrete structure lining is carried out to ecological drainage tunnel and diversion tunnel for step 4
Block closes ecological drainage tunnel work lock chamber, opens diversion tunnel work lock chamber, and diversion tunnel carries out overcurrent, is then shut off diversion tunnel work
Make lock chamber, carry out lower lock water storage, 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 needs
Ecological drainage tunnel work lock chamber is opened, carrying out ecology to downstream discharges 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.
Beneficial effects of the present invention：The structure and its construction that this diversion tunnel provided by the invention and ecological drainage tunnel combine
Methods and applications, compared with the existing mode that ecological drainage tunnel is separately provided, the present invention is solved due to diversion tunnel and ecology
Drainage tunnel is arranged apart and the problem of increasing quantities, construction investment and construction period, the cloth that is combined by two buildings
Pattern is set, construction diversion and the ecological requirement to discharge water is met, reduces quantities, reduce construction investment, shorten the duration；
With existing diversion tunnel compared with the structure of " dragon comes back " pattern that flood discharging tunnel combines, solves " dragon comes back " common height of pattern
The problems such as fast water cavity is destroyed, energy dissipating is difficult under the conditions of high water head, is suitable for the ecological drainage tunnel and diversion tunnel of middle and high head
In conjunction with arrangement.
The present invention is described in further details below with reference to attached drawing.
