Technical Field

The invention relates to municipal rainwater and sewage diversion, in particular to a one-inlet two-outlet pipeline diversion system and a diversion method, and belongs to the technical field of civil buildings and municipal water supply and drainage.

Background

At present, in a diversion well, a abandoning well and an intercepting well system, the system is composed of a water inlet pipe, a water outlet pipe and a sewage pipe, domestic sewage or initial rainwater and later stage rainwater in a drain pipe are diverted, wherein the domestic sewage or the initial rainwater is intercepted to the sewage pipe and then is conveyed to a sewage treatment plant for treatment and then is discharged after reaching the standard (further, the initial rainwater can be stored or intercepted to the sewage treatment plant for treatment and then is discharged after reaching the standard), and the middle and later stage rainwater is directly discharged to natural water.

In reality, devices for realizing the cut-off and conduction functions in a diversion well, a abandoning well and an intercepting well generally adopt electric control or hydraulic control. However, in reality, the following problems exist in the electric control: 1. flammable and explosive biogas is generally generated in a closed pipeline and a sewage environment, and a general electric control device is easy to explode and unsafe, so that an electric control part in contact with the biogas is required to have an explosion-proof function when the electric control device is applied, and therefore, an electric control system is expensive and high in cost; 2. under the severe environment of the second storm gas, the power failure can occur, and equipment in a diversion well, a flow abandoning well or a catch basin can not work normally after the power failure, so that the urban waterlogging and other situations occur; 3. under the second gas, the flooding conditions of the diversion well, the abandoning well and the intercepting well are between hours and days, so that the redundancy and the cost are too high by adopting an electric control device which is completely suitable for underwater use, and the flooding capacity of the common electric control device with the IP68 grade is insufficient within hours; 4. the device of the electric control system uses non-safe voltage, and the high voltage is unsafe and easy to have accidents; 5. after the electrical equipment is flooded, the electric leakage is easy to occur, and the electric shock danger exists; 6. the electric control equipment (a gate and a weir gate) needs an upward or downward stroke during operation, the urban ground is exposed, the urban landscape beautiful traffic is influenced, and the excavation area is large during construction; 7. the electric control system uses 380V three-phase power, and a municipal power grid cannot supply power, so that the problem of difficulty in power supply is solved.

Particularly, for the occasion requiring the concealed installation, the power supply and the generated cost of the electric control system are not easy to be solved. Hydraulic control also has certain problems: the hydraulic station uses a high-pressure oil pipe, and the cost of the hydraulic station and the high-pressure oil pipe is high; the high-pressure oil pipe is broken and leaks oil to pollute the environment; after the electrical equipment is flooded, the electric leakage is easy to occur, and the electric shock danger exists; the electric control equipment (the gate and the weir gate) needs an upward or downward stroke during operation, the urban ground is exposed, the urban landscape beautiful traffic is influenced, and the excavation area is large during construction. In addition, in the prior art, when a living district, a road district, a discharge port and the like are treated, only the sewage and rainwater conditions of the current position and the current area are considered, resource sharing is not carried out, and the treatment cost is high.
