Do you know what the sewage effect of the plastic inspection well is? And why is it used as an aid to road drainage?
First of all, we know that road drainage needs the assistance of plastic inspection wells to have a good effect. It is also often used in municipal engineering, and sewage is often produced in cities. But what is the drainage effect of inspection wells?

1. Dewatering and drainage. The clogging of the plastic inspection well will definitely produce some sewage. We need to use the mud pump to discharge the sewage in the shaft to the sludge at the bottom of the well, and then divide the inspection well into sections according to the length of the well pipe. The section between two inspection wells with the same pipe diameter is one. The high-pressure water truck that dilutes the sludge will fill the inspection well with water, and then use the dredger to mix and dilute the sludge passing through the shaft, Manually and mechanically mix until the sludge is diluted into the water.
2. Set some plugs to block the water inlet pipe mouth of the well chamber at the working section from top to bottom, and then block the water outlet of the downstream inspection well and other pipeline openings, leaving only the water inlet and outlet of the pipe section.

3. Sewage suction trucks are used to absorb sludge. The sludge at the bottom of the well is sucked clean with professional tools for sewage suction. A small amount of residual sludge from the two plastic inspection wells is pumped into the well chamber with a high-pressure water gun, diluted again, and the suction is completed.
4. The cleaning truck is used for dredging operation. Use the high-pressure cleaning truck to dredge the pipeline, extend the hose of the high-pressure cleaning truck into the lower part of the upstream inspection well, aim the water spout at the pipeline in the direction of water flow, and continue to absorb the indoor sludge in the inspection well downstream of the sewage pipeline.

5. Bottom ventilation of plastic manhole. It is an operation to prevent danger when the construction personnel go down the well. Before they go down the well, the construction personnel need to do is to ventilate the room, let the oxygen in the atmosphere fully enter the well. Before they go down the well, they need to be fully armed.
The drainage effect of the plastic inspection well is relatively good on the whole, and it can be used when the drainage is needed. To effectively solve the problem of sewage discharge, sewage has too many negative effects on people's lives, and it needs to be discharged in time.
