现代挖泥船装备了各种疏浚仪器仪表。挖泥船进行水下挖泥,不论是开挖维护航道、运河、港池,还是开挖水工建筑物的基槽,都有严格的尺度要求。例如航道具有一定的深度、宽度和曲率半径。操纵人员用肉眼不能直接看到水下施工的情况,为了按工程设计的要求准确施工,必须借助仪器或其 Modern dredgers are equipped with various dredging instruments. Dredgers for underwater dredging, whether it is excavation and maintenance of waterways, canals, harbor basin, or excavation of hydraulic structures of the base groove, there are strict scale requirements. For example, the waterway has a certain depth, width and radius of curvature. Operators with the naked eye can not directly see the underwater construction, in order to accurately engineering requirements of the construction, you must use the instrument or its
