principle

Dredging using wire rope grab, rely on the action of gravity, into the water to a certain depth, by the insertion of a mud layer and a closed grab to mining and grab sediment, then through the manipulation of ship crane mechanical lifting grab out of the water, swing to a predetermined position the sediment discharge into the hopper or mud barge, and so forth.

classification

Grab dredger is self-propelled and non self propelled two. In general, the tank is filled with mud, and the mud tank is filled with dump mud from the air to the dump area.

Key points of construction technology control

Transverse excavation method construction

Grab dredger for horizontal excavation. Operation timed assigns 5 mooring, main anchor cable length should be 200 to 300 meters, the anchor tail length should be 200 to 300 meters, high velocity of poor quality long timely. The edge should be thrown in mooring line outside the 100 meters. Near point positioning, anchored procedures and chain bucket ship basically the same.

The concurrent and countercurrent construction

Grab dredger should adopt concurrent construction. When the flow rate is not large or there is a reciprocating flow, it can be used as a counter current.
