冠诚钻探抽沙船：
清淤船，即清除水底沉积物的工具。动力一般有柴油机，电机两种。船体即浮体，采用拼装箱型结构。有清淤装置，动力装置，传送装置等。由动力驱动清淤装置清除水底沉积物，由传送装置送出到指定位置。挖斗式清淤船即链斗式挖沙船
绞吸式清淤船是清淤船的主用船型，由浮体，铰刀，上吸管，下吸管，泵，动力等组成。他利用下吸管前段的铰刀，耙头装置将水底沉积物切割搅动疏松后，经下吸管由泵吸起，有上吸管送出到指定位置。此船效率高，成本低。根据船型每小时处理沙水混合物在50方至500方。目前一些超大型清淤船处理能力已超1000方。
 

Crown-drilling pumping sand:
Dredging vessels, namely removal tool underwater sediments. Generally there are diesel powered motor two kinds. That buoy hull, using assembled box structure. Has dredging means, power means, transmitting means and so on. Powered device cleared by dredging the bottom sediments, sent by the transmitting device to the specified location. Bucket dredging boat that chain bucket dredgers
Cutter suction dredging ship is the ship's main dredging ship, the floating body, reamers, on straw, under straw, pumps, power and other components. He used under straw front of reamers, rake head unit will bottom sediments stirred loose after cutting through a straw by pumping down from there sent to the specified location on the straw. This boat high efficiency and low cost. 50 square sand-water mixture to 500 per hour according to the ship side. At present, some large dredging boat handling capacity exceeded 1000 party.
