链斗式挖泥船在施工中,对挖深的控制,是根据具体施工要求,通过操纵斗桥绞车,把斗链下放到要求深度来进行操作的。在施工中,随着水位涨落的不断变化,操纵人员亦不断地把斗桥相应地提高和降低至水位变化数字,以保证施工质量符合工程要求。以前,我局链斗式挖泥船都是以悬有铅 Bucket dredger in the construction, the control of digging depth is based on the specific construction requirements, by manipulating the bucket bridge winch, the bucket chain to the required depth to operate. In the course of construction, as water level fluctuates constantly, operators also continuously raise and lower the bridge to the water level change figures so as to ensure the construction quality meets the requirements of the project. In the past, my bureau’s bucket dredger was suspended with lead
