Abstract
The utility model discloses a kind of diversion tunnel, including the main hole being connected with upstream, the main hole is around dam and extends to downstream, and bifurcated is connected with ecological drainage tunnel and hole of releasing on the main hole barrel positioned at downstream.The utility model makes full use of limited building arrangement space, diversion tunnel is had flood discharge, emptying, the function of ecology water supply concurrently.To need not release hole and ecological drainage tunnel it is arranged apart, reduce hole digging amount, supporting amount and floor space, reduce cost.
Description
Technical field
The utility model belongs to water conservancy and hydropower technical field, more particularly to a kind of diversion tunnel.
Background technology
In Hydraulic and Hydro-Power Engineering, because dam is across two sides, flood has been intercepted, while has also blocked the water in downstream,
Therefore ecological drainage tunnel need to be set and provide ecological flowing water to downstream.When running into unconventional flood or dam and needing repairing, it is
The safety of dam is ensured, flood discharge, emptying and maintenance function are realized frequently with flood discharge emptying tunnel.
Conventional way is after dam is built up, and flood discharge emptying tunnel and ecological drainage tunnel are separately excavated in dam two sides,
But certain landform and river course can be so taken, and hole is dug and its supporting amount is big, cost is high.It is narrow for river course, flood discharge emptying
The limited engineering of building arrangement space, it is particularly problematic.
Utility model content
In view of the above-mentioned problems, the utility model aim to provide one kind occupy little space, excavated volume it is small, have concurrently flood discharge, emptying,
The diversion tunnel of ecological water supply function.
The utility model solve problem technical scheme be：A kind of diversion tunnel, including the main hole being connected with upstream, the master
Hole is around dam and extends to downstream, and bifurcated is connected with ecological drainage tunnel and hole of releasing on the main hole barrel positioned at downstream.
Preferably, emergency repair gate is provided with main hole entrance, hole outlet of releasing is provided with main gate or valve.
Specifically, ecological drainage tunnel and hole of releasing are connected by bifurcated pipe with main hole, the bifurcated pipe is branched off using armored concrete
Pipe or steel bifurcated.
Remarkable result of the present utility model is：
1. making full use of limited building arrangement space, diversion tunnel is set to have flood discharge, emptying, the work(of ecology water supply concurrently
Energy.
2. will need not release hole and ecological drainage tunnel it is arranged apart, reduce hole digging amount, supporting amount and floor space, reduction and make
Valency.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is horizontal layout schematic diagram of the present utility model.
In figure：The main holes of 1-；2- bifurcated pipes；3- releases hole；4- ecology drainage tunnels.
Embodiment
As shown in figure 1, a kind of diversion tunnel, including the main hole 1 being connected with upstream, the main hole 1 is around dam and extends to
Downstream, bifurcated is connected with ecological drainage tunnel 4 and hole 3 of releasing on the barrel of main hole 1 positioned at downstream.Ecological drainage tunnel 4 and release
Hole 3 is connected by bifurcated pipe 2 with main hole 1.The bifurcated pipe 2 uses Reinforced Concrete Bifurcated Pipes or steel bifurcated.
Emergency repair gate is provided with the main entrance of hole 1, the maintenance requirement in can meet to release hole 3, ecological drainage tunnel 4.
Release hole 3 outlet be provided with main gate or valve, to control water flow.
Ecological drainage tunnel 4, which exports, typically connects main gate, factory building, valve etc., to realize the work(of diversion and power or water supply
Energy.
Because the water inlet floor elevation of diversion tunnel is than relatively low, generally below level of dead water, and be higher than silt elevation, therefore can
Realize and carry out flood discharge in the flood season, can carry out emptying maintenance in the unusual time again, the work(that downstream ecology supplies water can also be realized
Energy.
Claims (3)
1. a kind of diversion tunnel, including the main hole being connected with upstream, the main hole is around dam and extends to downstream, and its feature exists
In：Bifurcated is connected with ecological drainage tunnel and hole of releasing on the main hole barrel positioned at downstream.
2. diversion tunnel according to claim 1, it is characterised in that：Emergency repair gate is provided with main hole entrance, is let out
Put hole outlet and be provided with main gate or valve.
3. diversion tunnel according to claim 1, it is characterised in that：Ecological drainage tunnel and hole of releasing pass through bifurcated pipe and main hole
Connection, the bifurcated pipe use Reinforced Concrete Bifurcated Pipes or steel bifurcated.
