冠誠鉆探抽沙船：
1、工作條件：利用雨天河水流速2厘米/秒以上進行工作。

2、工作原理：利用船動力帶動水泵，產生高壓水流進入噴水管，通過安裝噴水管上的噴水槍射出水流，將沉積河底的淤泥吹攪成混濁的水狀，隨河水流走，從而起到清淤作用。

3、技術特點：在噴水管設有相通的固定管和活動管，固定管和活動管上各設有噴水槍，活動管與固定管可折疊密封配合。當船行馳至橋墩或較窄河面時，可以將噴水管的活動管折疊起來以方便行馳，而固定管上的噴水槍繼續(xù)噴射水流。在較寬河面時，則將活動管展開，使活動管與固定管上的噴水槍同時噴射水流來清理淤泥。從而避免了噴水管的長度受橋墩和船體大小限制，操作靈活，大大提高了使用效率和清淤效果。

Guancheng drilling sand pumping:
1, working conditions: the use of rainy river flow velocity of 2 cm / sec or more work.
2, the working principle: the use of ship power driven pumps, generating high pressure water flow enters the water spraying pipe, through the installation of spray gun spray pipe injection water, depositing the slime of the river bed of blowing and stirring into turbid water state, float down the river, thus plays the role of dredging.
3, technical features: the water spraying pipe is provided with a fixed tube and a movable pipe communicated, fixed tube and a movable tube are respectively arranged on the spray gun, the activities of pipe and the fixing tube can be folded seal matching. When the ship runs to pier or narrow river, can spray pipe movable tube folded for easy relaxation, while the spray gun fixing pipe continues to spray water. In a wide river, the active pipe expansion, so that the water spray gun active pipe and the fixed pipe and spray water to clean the silt. To avoid spray pipe length by the pier and ship size limit, flexible operation, greatly improving the efficiency and effect of dredging.
