Shanghai pipeline desilting work has become an important task for the drainage department that cannot be ignored. If a large amount of debris and cement sand from infrastructure construction sites are discharged into the drainage pipeline, sedimentation and siltation will cause pipeline blockage. Failure to desilt and unblock pipelines will cause overflow of sewage, pollute the environment, and bring trouble to people's lives.
Shanghai Pipeline Dredging Company has been engaged in the dredging and dredging business of pipelines, sewers, box channels, sewage sedimentation tanks, etc. for many years. It has accumulated many years of practical experience and many of the most influential professional skills in the industry. Our company specially invented dredging. machinery, and has applied for patents. The company has formulated a variety of dredging machinery and equipment and a variety of professional dredging programs.
The operation process of Shanghai Pipeline Dredging Company
1) Pipeline dewatering and drainage
Use a mud pump to discharge the sewage in the inspection well to the silt at the bottom of the well. Divide the pipelines that need to be dredged into segments. The segmentation method is based on the diameter and length of the pipe. A section is between two inspection wells of the same diameter.
2) Dilution of sludge in pipelines
The high-pressure water truck pours water into the well chamber from the two segmented inspection wells, and uses a dredge to stir the sludge in the inspection wells and sewage pipes to dilute the sludge. Manual work must be coordinated with machinery to continuously Stir the silt until the silt is diluted into the water.
3) Pipeline sewage suction
Use a sewage suction truck to suck out the sludge in the two inspection wells. The remaining small amount of sludge in the two inspection wells is injected into the well chamber with a high-pressure water gun to impact the sludge at the bottom of the well, dilute it again, and then The suction is complete.
4) Pipeline waste interception
Set up plugs to block the entrance of the well chamber water inlet pipe at the first working section from top to bottom, and then seal the outlet of the downstream inspection well and other pipelines The outlet is blocked, leaving only the water inlet and outlet of this section of pipe.
5) Pipeline high-pressure cleaning truck to clear the pipeline
Use a high-pressure cleaning truck to clear the pipeline. Extend the water hose of the high-pressure cleaning truck into the lower part of the upstream inspection well, and aim the water nozzle at the pipe in the direction of the pipe flow to spray. Inspection wells downstream of water and sewage pipes continue to absorb indoor sludge.
6) Pipe ventilation
Before construction workers enter the inspection well, the oxygen in the atmosphere must be allowed to enter the inspection well or a blower must be used for ventilation and ventilation. The oxygen content in the well must be measured. Construction workers must enter the well. Wear a seat belt, gas mask and oxygen tank.
7) Pipeline desilting
After arranging safety measures for construction workers before going down to the well, manually clean up the remaining bricks, stones, some silt and other residues in the inspection well until the cleaning is completed.
The Shanghai Pipeline Dredging Company uses high-pressure cleaning vehicles, or manual, traction, push-pull and other methods to clean the silt in the pipeline out of the pipeline, and then transport it to the designated place. If the pipeline needs to be cleaned until there is no silt, it must be repeated To clean the inner wall of the pipeline, you can use pipeline inspection visual imaging to take pictures and see the internal conditions of the pipeline to understand the desilting situation of the pipeline. Used for dredging construction of rainwater pipes, sewage pipes, open channels and culverts of different depths and diameters.
