This utility model solves its technical problem and be the technical scheme is that the diversion tunnel structure that can carry out the maintenance of tunnel lock chamber section,
Including diversion tunnel barrel, the Upstream section of diversion tunnel barrel is by maintenance tunnel, described is provided with lock chamber structure, also in maintenance tunnel
Including one maintenance water-conveyance tunnel, the import of described maintenance water-conveyance tunnel is connected with upper river, maintenance water-conveyance tunnel outlet and
Diversion tunnel barrel is connected, and link position is positioned at the downstream of lock chamber structure, and the barrel section at maintenance water-conveyance tunnel is provided with maintenance lock
Room is also provided with gate.
Further, the described position by maintenance tunnel inner brake cell structure is higher than barrel downstream, and tool in lock chamber structure
There are two apertures, in each aperture, are equipped with gate.
Further, in two apertures of described diversion tunnel lock chamber structure, it is equipped with two gates, is respectively closure gate and inspection
Repairing gate, wherein closure gate is positioned at the upstream of bulkhead gate.
Further, described closure gate and bulkhead gate being equipped with gate sealing, the gate sealing of closure gate is positioned at lock
Passage downstream, the gate sealing of bulkhead gate is positioned at gate upstream.
Further, the described approach channel upstream by the water inlet of maintenance tunnel is provided with maintenance cofferdam.
The beneficial effects of the utility model are: by arranging a maintenance water-conveyance tunnel on diversion tunnel barrel side, utilize maintenance defeated
Diversion tunnel lock chamber is overhauled during supplying water by water tunnel, can be under the diversion tunnel not possessing maintenance condition before lock, to water conservancy diversion
Tunnel import lock chamber structure and gate recess embedded part overhaul, it is ensured that under diversion tunnel gate, lock is smoothly and power benefit, exists simultaneously
After lock under maintenance diversion tunnel, can be by maintenance water-conveyance tunnel bleed downstream river channel ecology flow, it is ensured that downstream ecology is stable.
Accompanying drawing explanation
Fig. 1 is this utility model horizontal layout schematic diagram.
Fig. 2 is overhauled tunnel profilograph.
Fig. 3 is the profilograph of maintenance water-conveyance tunnel.
Being labeled as in figure, 1-diversion tunnel barrel, 2-lock chamber structure, 3-blocks gate, 4-bulkhead gate, and 5-overhauls water delivery
Tunnel, 6-overhauls lock chamber, 7-gate, and 8-overhauls cofferdam, and 9-is overhauled tunnel.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
As it is shown in figure 1, this utility model includes diversion tunnel barrel 1, the Upstream section of barrel is by maintenance tunnel 9, by maintenance tunnel
It is provided with lock chamber structure 2 in 9, is provided with a maintenance water delivery tunnel paralleled with by maintenance tunnel 9 with by the side of maintenance tunnel 9
Hole 5, the import of described maintenance water-conveyance tunnel 5 is connected with upper river, the outlet of maintenance water-conveyance tunnel 5 and diversion tunnel barrel 1
Being connected, and link position is positioned at the downstream of lock chamber structure 2, the integral position of maintenance water-conveyance tunnel 5 can be less than by maintenance tunnel 9
Position, the barrel section at maintenance water-conveyance tunnel 5 is provided with maintenance lock chamber 6 be provided with gate 7.The work that this use is novel
Principle is: downstream sluiced by by maintenance tunnel 9 and diversion tunnel barrel 1 under normal circumstances, when needs are to by maintenance tunnel 9
Lock chamber structure 2 when overhauling, open the gate 7 in maintenance water-conveyance tunnel 5, utilize maintenance water-conveyance tunnel 5 that downstream is let out
Water, thus realize the maintenance to lock chamber structure 2, and when overhauling, do not affect downstream ecological environment.
The described position by maintenance tunnel inner brake cell structure 2 is higher than barrel downstream, and has two holes in lock chamber structure 2
Mouthful, it is equipped with gate in each aperture.The position of lock chamber structure 2, higher than barrel downstream, can be carried out by certain gradient
Transition, as in figure 2 it is shown, the water that its purpose is to prevent flowing through from maintenance water-conveyance tunnel 5 refluxes at diversion tunnel barrel 1 again
In lock chamber structure 2, being smoothed out of impact maintenance.Two apertures are set in lock chamber structure 2, primarily to be easy to arrange
Less gate, improves the stability of gate closure, and is also beneficial to maintenance.
Further, in two apertures of described diversion tunnel lock chamber structure 2, it is equipped with two gates, is respectively closure gate 3
With bulkhead gate 4, wherein closure gate 3 is positioned at the upstream of bulkhead gate 4.The purpose of two gates is set primarily to just
In quickly discharging by the flowing water in maintenance tunnel 9 and avoiding river to flow backwards, its work process is: when needs carry out lock chamber knot
When structure 2 overhauls, it is first turned on overhauling the gate 7 of water-conveyance tunnel 5, and simultaneously closes off the bulkhead gate 4 in lock chamber structure 2,
Now river can only be drained from maintenance water-conveyance tunnel 5, and will not be back at diversion tunnel barrel 1 in lock chamber structure 2, treats
After water level decreasing, the hydrops of lock chamber structure 2 Upstream section drained by available water pump, then carries out the maintenance to closure gate 3.
In order to improve closure gate 3 and the dash performance of bulkhead gate 4, described closure gate 3 and bulkhead gate 4 are all provided with
Having gate sealing, the direction that root has main dash is different, and the position that gate sealing is arranged is the most different, and the gate of closure gate 3 is only
Water level is in gate downstream, and the gate sealing of bulkhead gate 4 is positioned at gate upstream.
Further, in order to drain the river of lock chamber structure 2 Upstream section faster, can overhauled after 4 times locks of bulkhead gate
The approach channel upstream of tunnel 9 water inlet is provided with maintenance cofferdam 8, blocks river course water, prevents river course water from entering by maintenance water conservancy diversion tunnel
In hole 9 and lock chamber structure 2, to lock chamber xoncrete structure and gate recess after pump drainage falls the hydrops overhauled in tunnel 9 the most again
Embedded parts etc. carry out major tune-up.After being completed by the maintenance service work such as tunnel 9 import lock chamber xoncrete structure and gate recess embedded part,
Remove again by the maintenance cofferdam 8 of maintenance tunnel 9 import barrel upstream, and close the gate 7 overhauling water-conveyance tunnel 5, complete inspection
Repair work.
This utility model solves to be needed to carry out tunnel makeup of the imports maintenance and unconditionally arrange the contradiction between access path, it is to avoid
Because the tunnel makeup of the imports causes lower lock unsuccessfully to cause power benefit to lose without maintenance condition, under by maintenance tunnel after lock, can be by
Maintenance water-conveyance tunnel bleed downstream river channel ecology water, this structure solves two technical barriers simultaneously, creates economic benefit
Protect again ecological environment, there is good practicality and application prospect.
