Dredging method of plastic inspection well

Winch Desilting

Use bamboo pieces to pass through the parts that need cleaning The Conduit Then use the winch on the inspection shaft at both ends of the pipeline to twist the steel wire rope to and fro, so that the sediment can be pushed into the downstream inspection shaft by clearing tools. The winch has manual, motor, electric, etc. There are also many kinds of clearing tools, which are selected according to the pipe diameter and user needs. This method is applicable to pipelines of various diameters, and is more suitable for pipelines with serious siltation and dense sludge bonding. http://www.sdpegj.com/

Trencher

The desilter, which is used for rigid sealing between the same pipe, passes through the pipe as a jet under the action of air or liquid pressure, and removes foreign matters in the pipe. This method requires smooth and regular pipe wall, and not too much sediment, so it is mostly used for desilting of nuclear power and industrial metal sewage pipes.

High pressure water jet

A widely used desilting method, using a high-pressure water jet equipped with large water pot , motorized pipe coiler, high-pressure water pump , water jet nozzle, etc. Vehicle engine drive during operation High pressure pump , pressurize the water and send it to the water jet nozzle, and the reaction force generated by its backward injection will make the water jet nozzle and the rubber hose move in the opposite direction together, while cleaning the pipe wall; When the nozzle reaches the downstream inspection well, the motor winch will withdraw the hose, and the water jet nozzle will continue to spray water to flush the residual sediment to the downstream inspection well, which will be sucked away by the mud suction truck. http://www.zbpegj.com/

Scouring and desilting

For the limitation of inspection well size, the components of the whole device must be assembled in the sewer. During operation, the sewage accumulates in the upstream of the device. When it reaches a certain height, water flows in the front of the device to remove the sediment. Once enough sediment is washed away, the device will move several CM downstream. This method has obvious advantages.
