Type pumping sand is mainly used for drilling large waters or vehicle, dredging vessels can not enter the battlefield or reservoirs, rivers and lakes used, which works with the drill bit through the mud layer, using high-pressure water pumps generate pressure, impact of sediment by water cannons the impact of sediment deposited to form a floating state. The sediment is then pumped by pumping sand and then piped to the destination. Ship design novel, easy operation, high efficiency, suitable for river dredging, lake and reservoir dredging, land reclamation, port cleaning, pumping sand, sand and other construction
