Methods for desilting plastic inspection wells

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 the cleaning tools. The winch has manual, motor, electric, and cleaning tools http://www.sdpegj.com/ There are also many kinds, which can be 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.

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.

A similar pneumatic trenching machine uses compressed air to send the desilter from one inspection well to another, and then the winch pulls the wire rope at its tail to open the wings, and the sediment is scraped out of the pipeline with the desilter. Another flexible shaft trench machine is electric machinery Or the power generated by the car engine is transmitted to the dredging tool through a flexible shaft, and the rotation of the flexible shaft makes the dredging tool rotate and move forward to loosen the sediment and scrape it into another inspection well.

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. During operation, a car engine drives a high-pressure pump to pressurize the water and send it back http://www.zbpeg.com/ The reaction force generated by the backward injection of the incident water nozzle makes the water jet head and the hose move in the opposite direction together, and also cleans 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.

This method can be applied to pipes of various shapes and specifications. Based on cost and scouring effect, it is usually limited to pipes with diameter less than 3250px, and the cost of cleaning water is relatively high; Moreover, the influence of mixed sediment particles in high-pressure water jet on the pipe wall cannot be ignored.

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.
