冠誠鉆探抽沙船：
清淤船，即清除水底沉積物的工具。動(dòng)力一般有柴油機(jī)，電機(jī)兩種。船體即浮體，采用拼裝箱型結(jié)構(gòu)。有清淤裝置，動(dòng)力裝置，傳送裝置等。由動(dòng)力驅(qū)動(dòng)清淤裝置清除水底沉積物，由傳送裝置送出到指定位置。挖斗式清淤船即鏈斗式挖沙船
絞吸式清淤船是清淤船的主用船型，由浮體，鉸刀，上吸管，下吸管，泵，動(dòng)力等組成。他利用下吸管前段的鉸刀，耙頭裝置將水底沉積物切割攪動(dòng)疏松后，經(jīng)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。根據(jù)船型每小時(shí)處理沙水混合物在50方至500方。目前一些超大型清淤船處理能力已超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
