此船構(gòu)造簡單，主要有高壓水泵，吸沙泵，動力裝置，上下吸管，吸沙龍頭等組成。主要用途是把岸邊水底的物料用砂泵吸起輸送上岸。也可用于短距離輸送的取沙清淤工程。復合抽沙船：此船兼有絞吸式，射吸式兩船優(yōu)點。抽沙船適用于水庫庫尾的清淤。也有將噴射泵裝在絞吸式抽沙船的水下吸泥管中，作為一種輔助性的吸機具，以提高絞吸式抽沙船的沙漿濃度，增加挖深能力。

The ship is simple in structure, mainly with high pressure water pump, sand suction pump, power device, upper and lower suction pipe, suction head, etc.. The main purpose is to shore underwater materials use the pump suction conveying ashore. Can also take the sand dredging project for short distance transportation. Composite pumping sand: this ship has two advantages of cutter suction, suction jet. Suitable for pumping sand reservoir tail dredging. Also has jet pump installed in the cutter suction sand pumping water suction tube, as a auxiliary suction machine, in order to improve the cutter suction dredger slurry concentration, increase of digging depth.
