Cutter suction dredger is currently used in the sparse beach project a wider ships, it is the use of suction pipe water pipe installed around the front end of the rotary cutter device, river sediment will be cut and stir, and then suck clay pipe sediment material from the cutter, with a strong pump power, material buildup of sediment delivered to the field, it's dredging, mud, dumping and other work processes can be completed once continuous, it is a high efficiency, lower cost dredger is a good underwater mining machinery.
Cutter suction dredger has the following favorable properties:
1, widely cutter suction dredger uses, can work in rivers and lakes for dredging, channel excavation, land reclamation. In exceptional circumstances cutter installed on the power cutter suction dredger equipment without blasting to excavate basalt and limestone rock formations.
2, high cutter suction dredger working efficiency, yield, far away from the pump. Large cutter suction dredger yield up to several thousand cubic meters per hour; the sand or crushed rock material through the mud pumps rely on a powerful driving force and mud pipelines, pumping out a few kilometers outside.
3, a simple cutter suction dredger to operate, easy to control. Dredger rely on the stern of the steel pile trolley position and step by measuring cable cutter boom and fixed two Trench two measured anchor winch by traction, hatchback swing cutter cut sediment material in must work under the control of the swing angle, the twist move material through the mud tube pump to lose yard. Dredger stepping alternately by the two piles movement forward.
4, a large cutter suction dredger with a self-propulsion system. When the migration can self-propelled place. Small underwater dredger mostly non-self-propelled system, by the tug towing. Small dredger can design constructed assembled, transported to the site by road, after the assembly can be used.
5, cutter suction dredger economy is good. Mining and transportation of materials once completed, with no other ship boat, several handling. Relatively low cost of the project.
