Description
Technical field
The present invention relates to municipal rainwater, sewage separation, and in particular to a kind of pipeline shunt system and shunt method belong to the people
With building and municipal plumbing technical field.
Background technique
At present in shunting well, abandoned stream well and Vatch basin system, system is all by water inlet pipe, outlet pipe and sewage pipe group
At, by drainpipe sanitary sewage or initial rainwater, later period rainwater shunt, wherein sanitary sewage or initial rainwater
Qualified discharge (can also further store initial rainwater after being transported to sewage treatment plant's processing after being trapped to sewage pipe
Or shut off to sewage treatment plant's processing rear discharge up to standard), rainwater or middle and later periods rainwater are directly discharged in natural water.
Realize that cut-off and the device of conducting function generally use Electronic control in reality in shunting well, abandoned stream well and Vatch basin
Or hydraulic control.However there are the following problems for Electronic control in reality: 1, generally can in closed pipeline and Sewage Environment
Inflammable and explosive biogas is generated, it is dangerous that the device of general Electronic control class is easy explosion, therefore is applying Electronic control class
Device when can all require the electric control part contacted with biogas that must have explosion prevention function, therefore the price of automatically controlled class system just compares
Costly, at high cost；2, it under the second gas of storm wind more rugged environment, can all be shunted after powering off there is a situation where powering off
Equipment in well, abandoned stream well or Vatch basin can not work normally, thus situations such as causing urban waterlogging generation；3, sudden and violent second gas
Under, there is a situation where waterflooding between a few hours and a couple of days in shunting well, abandoned stream well and Vatch basin, in this way using entirely appropriate
The electric control gear used under water is excessive with regard to redundancy and cost is excessively high, and the electric control gear waterflooding ability of common IP68 grade is in number
Within hour, the case where there is also scarce capacities；4, the device of electric-control system uses non-security voltage, and high-voltage electricity is uneasy
It is prone to accidents entirely；5, after electrical equipment waterflooding, it is easy electric leakage, there are Danger Electric shock risks；6, control panel (gate, weir gate)
Stroke upward or downward is needed at runtime, exposes urban ground, excavation face when influencing urban landscape beauty traffic, and constructing
Product is big；7, electric-control system uses the three-phase electricity of 380V, and municipal power grid cannot power, and there is a problem of power supply hardly possible.
Particularly, for requiring the occasion of hidden installation, and for the expense of power supply and the generation of electric-control system not legibility
Certainly.Equally there is also some problems for hydraulic control: hydraulic station uses high-pressure oil pipe, the higher cost of hydraulic station and high-pressure oil pipe；
High-pressure oil pipe rupture oil leak pollutes the environment；After electrical equipment waterflooding, it is easy electric leakage, there are Danger Electric shock risks；Control panel (lock
Door, weir gate) stroke upward or downward is needed at runtime, expose urban ground, influences urban landscape beauty traffic, and construct
When excavation area it is big.In addition, only considering to work as when in the prior art renovating life section, road section and row's mouth etc.
The sewage and rain event of front position and region, do not carry out resource-sharing, and treatment cost is higher.
Summary of the invention
For the defect at high cost that automatically controlled safety problem and hydraulic control exists in the prior art, inventor is considered
Use the device of compressed air as a source of power.The smaller relatively safety of pneumatically operated pressure, and existing compression is empty
Gas occurs and control device mature and reliable price economy, and compressed air will not introduce secondary pollution, and blowing plant is without explosion
Risk.Compressed air control apparatus can long-time waterflooding, however due in pipeline situation it is complicated, how using compressed air as moving
Power come controlled and guaranteed safety, realization at low cost be an awkward problem, main problem is pipeline in the process
Design and control need to meet it is subsequent quickly, facilitate dilatation, creative research and work are passed through by inventor team, for state
The reality of the drainage pipeline networks of interior combined system and separate system is set out, and technical solution of the present invention is had developed, the road rain
Main shunting well is arranged on municipal storm sewer the dynamic processing system that shunts of aqueous vapor, total by conveying main pipe progress to gas
