Description
Technical field
The present invention relates to municipal works fields, and in particular to a kind of reverse-filling method and system applied in row's mouth.
Background technique
At present in shunting well, abandoned stream well and Vatch basin system, system is all by water inlet pipe, outlet pipe and to cut dirty pipe group
At carrying out the device that reverse-filling uses all is to use gate or weir gate to carry out the reverse-filling of corresponding outlet pipe, gate valve
Power source be electricity or it is hydraulic.However there are the following problems for Electronic control in reality: 1, in closed pipeline and Sewage Environment
In can generally generate inflammable and explosive biogas, it is dangerous that the device of general Electronic control class is easy explosion, therefore in application electricity
The electric control part contacted with biogas can be all required when the device of dynamic control class must have an explosion prevention function, therefore automatically controlled class system
Price is at high cost with regard to more expensive；2, it under stormy weather more rugged environment, can all be powered off there is a situation where powering off
It can not work normally with the equipment in heel row mouth well, abandoned stream well or Vatch basin, thus situations such as causing urban waterlogging generation；3, sudden and violent
Under rainy day gas, there is a situation where waterflooding between a few hours and a couple of days in Pai Koujing, abandoned stream well and Vatch basin, has used in this way
The full electric control gear for being suitble to use under water is excessive with regard to redundancy and cost is excessively high, and the electric control gear waterflooding energy of common IP68 grade
Power is within a few hours, the case where there is also scarce capacities；4, the device of electric-control system uses non-security voltage, and high pressure
Electricity is dangerous to be prone to accidents；5, after electrical equipment waterflooding, it is easy electric leakage, there are Danger Electric shock risks；6, 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；7, electric-control system uses the three-phase electricity of 380V, and municipal power grid cannot power, difficult there are power supply
Problem.
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 to the equipment used is there are other than the above problem, there is also cannot for existing Vatch basin, row's mouth well or abandoned stream well
Enough accurate shunting discharges for carrying out sewage and rainwater, and there are security risk, the water for being easy to happen spontaneous combustion water body flows backward into well
In vivo, urban waterlogging is caused.
Summary of the invention
To solve the above problems, the present invention provide it is a kind of apply row mouth anti-down irrigation method securely and reliably can be accurate
