Description
Technical field
The utility model relates to municipal drainage technical fields, and in particular to a kind of flood control tunnel.
Background technique
City big flood has become the increasingly serious development challenge that fast-developing country faces.Flood is Asia and peace
The foreign most common natural calamity form in area, uncertain characteristic requirements find out new solution to prevent social property
Safety is affected by it.The weakness of existing urban flood defence facility becomes obviously in nearest flood damage, and this protection demand is
Improve existing flood control infrastructure and implement innovative technology and provides new opportunity.
Past, the Hydraulic Tunnel for accommodating various waterpower infrastructure have been built up, although most well-known infrastructure is to use
In communications and transportation.There have been tunnel is used for sewer and draining to the Hydraulic Tunnel of urban inner, also has few about before 80 years
Part is for controlling flood (such as Chicago).The construction cost in this tunnel is costly and time-consuming.
Between nineteen twenty to 1940, with the significant propulsion of globalization and urbanization process, for draining and the water of blowdown
Work tunnel is more and more.With global warming and climate change, the natural calamity as tsunami and flood increases.Tunnel is upper
A initial stage in century is unattractive, it lags far behind the tunneling technique of today.
From that time, since over half a century, a large amount of foundation construction facilities in city provide livable city for man and nature
Condition.It is obvious that spatial surface is ultimate attainment using having arrived.
Instantly the critical point of multidimensional disaster has been had arrived at, it is therefore desirable to which environment is provided under the conditions of flood and tsunami to be held
Continuous urban life.
Utility model content
The purpose of this utility model is exactly to provide a kind of flood control tunnel to overcome the problems of the above-mentioned prior art.
The purpose of this utility model can be achieved through the following technical solutions: be used for including being arranged in coastal cities area
It collects multiple water inlet vertical shafts of surface water, marine bottom is set for the water exit shaft of flood to be discharged and is connected to perpendicular into water
Connection tunnel between well and water exit shaft, the water inlet silo bottom buried depth be greater than water exit shaft bottom buried depth, and closer to
The water inlet silo bottom buried depth of seashore is more shallow.When coastal cities area meets with big rainfall, rainwater passes through water inlet vertical shaft toward underground
Flowing imports in connection tunnel, since the height in coastal cities area is higher than sea level, so the flood being connected in tunnel can be with
Ocean is drained into from water exit shaft.
Specifically, the utility model follows the vertical shaft/tunnel system hydraulic model being applied in outlet tunnel,
And water is transported from water inlet silo bottom to ocean by deep water tunnel.Once vertical shaft/tunnel system is established, with past tunnel
Interior water filling, the water level in tunnel will rise.After the flood gate of discharge outlet is opened, the water in vertical shaft will converge with marine water
It closes.Due to different specific gravity, fresh water finally floats on above salt water, generates waterpower.Water flow by by the turbine of water-power plant,
It produces electricl energy.
Preferably, the depth of the water inlet vertical shaft is apart from coastal cities area 150~250m of earth's surface, the water outlet
Vertical shaft and ocean are 10~15km at a distance from the intersection of coastal cities area, and the depth of the water exit shaft is distance Hai Ping
75~110m of face.The water inlet vertical shaft of the utility model and water exit shaft all should be equipped with elevator or helical orbit or other function is identical
Structure, with lamp convenient to overhaul operation.
The water outlet of the water exit shaft is equipped with sluice to be opened/closed.When not occurring big rainfall, sea is prevented
Water, which flows backward, enters connection tunnel.
Water level sensor is equipped in the water inlet vertical shaft, the flood control tunnel is equipped with and connect with water level sensor for driving
The control centre of dynamic sluice opening and closing.Water level sensor can show the motion information of water in tunnel, then pass through control centre
The opening and closing of sluice is controlled, is discharged extra flood in time.
The turbine generator in the connection tunnel immediately below ocean and coastal cities area intersection, can also
Water pump is arranged.This turbine generator can provide energy for the control centre, and rainwater is flowed to ocean from land
Energy fully utilize.It is arranged in addition, setting water pump can will be connected to the water in tunnel if necessary from water exit shaft
To ocean.
The described water inlet vertical shaft, water exit shaft and to be connected to the material in tunnel be prefabricated reinforced concrete tunnel duct piece.?
When preparation, needs several points and needs to pay attention to:
1, prefabricated reinforced concrete tunnel-liner is connected in its longitudinal direction with circumferential seam setting connector, and connector is completely embedding
Enter junction and invisible in junction；
2, the arrangement for being connected to tunnel and vertical shaft follows earth's surface flood more than accessible to greatest extent to need underground to transport
Defeated logic；
3, the seam of concrete surface is dynamic with the frictionless flow for realizing water；
4, the design in tunnel is to realize the smallest friction requirements to reach highest operational efficiency；
5, tunnel cross sectional design need to be optimized, keep its size minimum.
Compared with prior art, the beneficial effects of the utility model are embodied in: the city coastal area that protection flood is easily sent out,
And the concept of a hydraulic structure is provided, it is more than that regulation is controllable by tunnel/silo system processing in high density settling pond group
The flood of water makes it through water-power plant while flood is discharged and produces electricl energy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 is water inlet vertical shaft, and 2 be water exit shaft, and 3 be connection tunnel, and 4 be turbine generator and water pump, and 5 be to let out
Big vast lock, 6 be coastal cities area, and 7 be ocean.
