Unmanned robot dredging
What is unmanned robot dredging?
Using hydraulic unmanned robot, remote controlled Vacuum operation is conducted. It can be applied to dredging work for inside of pipeline, tank and reservoir using the robot, securing safety and efficiency through unmanned equipment operation.
Range and advantage of unmanned robot dredging.
- For vacuum operation in various place including inside dredging on pipeline, tank and reservoir
- For dredging the sediment generated by earth and sand, sludge and so on
- Enable to manage against various risks such as toxic gas inflow or submersion
- Securing work efficiency through long time consecutive works by hydraulic mechanism

General Dredging
The concept of dredging.
It is a cleaning operation using high pressure Jet-Cleaning equipments and high vacuum suction vehicle. All the wastes and sludges(sand, pebbles and other matter) are pushed by high pressure water that is discharged from high pressure jet-cleaning equipment then these wastes are sucked into suction hose of vacuum car that is attached to manhole, making dredging completely.
Range of dredging operation
- washing dredging sediment in drainage
- washing & dredging the inside of soil pipe, sewage pipe
- drain pipe scale washing
- Walls on tunnel or deteriorated washing
- cleaning various types of pipe including hume tube, 촉구, capped ditch(복개천), box pipe
- dredging sludge inside settling tank, collecting tank(집수조), aeration tank
- dredging sludge inside big scale tanks
- dredging sludge in retarding basin, reservoir and riverside
- big scale manhole and underdrain dredging
- sewage treatment facility dredging
- dredging sludge in waste water treatment plant
- dredging earth and sand on agricultural irrigation canal
- earth and sand suction dredging on drainage pump station
- iron material, liquid, particle, solid sludge dredging

Sewage culvert dredging
Sewage culvert dredging operation using shovel loader robot
- This technology is to operate dredging the sludge inside sewage pipeline by combining unique technique on the methodology of dredging culverts.
- This shovel loader robot can move over sediments and remove them; it consists of control system that can also load them, move them and thrust them out of sewage culvert. This robot is composed of electric and hydraulic operating equipments, is remote controlled to move in all directions and gives monitoring the operation remotely to secure the operator from the environmental or industrial accidents such as Gas leaking or influx. This new method using shovel loader is a way better constructable with efficiency and economic cost compared to previous method that could cause safety incidents of workers on the field.
