Description
Technical field
The present invention relates to plumbing and hydrotechnics field, particularly to a kind of draining deep tunnel spiral channeltype rotation
Flow through shaft.
Background technology
Deep layer outlet tunnel facility utilizes city Deep underground space draining and the facility of water-retention, mesh as a kind of
Before municipal drainage at home and abroad prevention waterlogging engineering in be used widely, its Main Function is by city during heavy showers
The rain sewage that city's shallow-layer drainage system cannot discharge transfers to Deep underground space to save and transfers discharge, it is ensured that city
Earth's surface, city and Subsurface do not produce waterlogging and cause city productive life to be a greater impact.Urban surface
And the rain sewage of Subsurface drainage system is to the transfer process of Deep underground space outlet tunnel facility
In, need by the vertical shaft facility connecting earth's surface and Subsurface drainage system and deeper subsurface outlet tunnel
Carry out transferring of rain sewage, and require simultaneously vertical shaft realize during transferring rain sewage the energy dissipating of current with
Aerofluxus, to guarantee that the current entering deep layer outlet tunnel become a mandarin stable and do not carry substantial amounts of blending steam, because of
This, the appropriate design transferring vertical shaft is transferred for rain sewage and the safe and stable operation pole of deep layer outlet tunnel
For important.
At present, municipal administration and hydraulic engineering construction develop two big class main vertical shaft facilities in implementation process, point
Wei drop formula vertical shaft and cyclonic flotation column.

The form closing facility is different.Being broadly divided into eddy current, to enter head piece vertical shaft, tangent-type vertical shaft and spiral ramp formula perpendicular
Well etc..Wherein, eddy current enters head piece class and tangent-type vertical shaft mainly enters the physique of head piece to water by vertical shaft
Stream forms water conservancy diversion, makes the current in entrance vertical shaft form the eddy flow form declined along vertical shaft spiral inner wall, with reality
The target of existing eddy flow energy dissipating；While spiral ramp formula vertical shaft is except forming eddy flow at the port part current that become a mandarin,
The corresponding spiral ramp of vertical shaft inner facility, to realize while current eddy flows enters vertical shaft, passes through spiral shell
Rotation ramp cyclone water stream is carried out further water conservancy diversion, so that it is guaranteed that current in vertical shaft all the time with the shape of eddy flow
Formula falls, it is achieved more efficient lasting eddy flow current, and maximizes the energy dissipating target of current.Eddy current and tangent line
The range primary limitation of formula vertical shaft is the draining transmitting system of drop less (within general 20m),
When drop is bigger, current are gradated as dropping by eddy flow in vertical shaft, and follow-up facility is formed greater impact
And carry steam in a large number, affect the stable operation of follow-up facility；Although spiral ramp formula vertical shaft avoids above
The defect of rotational flow silo, but it is to the changes in flow rate of the current that become a mandarin and bigger drop adaptability the most relatively
Difference, when becoming a mandarin less than the current of design discharge or vertical shaft entirety drop is excessive, due to flow rate of water flow flow relatively
Little or drop is relatively big, easily departs from ramp, form drop in vertical shaft after the popular segment distance of spiral ramp,
Meanwhile, such vertical shaft is suitable only for the drainage system that a road becomes a mandarin, in the shaft top have two and two with
