1.Flow rate The dredger is operated under certain working conditions, and its output flow is rated under normal conditions. In order to obtain maximum productivity, it is necessary to choose the optimal construction scheme and [...]
Excavation of hard clay: the water content of hard clay is low, high viscosity and hardness, and is not easy to collapse and excavation broken. It is difficult to excavate with bucket wheel head cutter, [...]
Floating pipe laying  Float pipe of a certain length shall be laid after the stern pipe of the cutter suction dredger conveying pump. The floating pipe adopts the form of a plastic pontoon-covered steel pipe, [...]
Failure maintenance of the hydraulic system of spud of cutter suction dredger  In the process of repairing the fault of the hydraulic system of spud of cutter suction dredger, the staff should first confirm [...]
Transform the dredging depth  Based on the designed excavation length, the distance is increased, and the mechanical equipment in the construction process is reformed according to the needs. It is important to note that [...]
Daily maintenance and inspection of early-warning fire equipment. Â The ship fire alarm device shall be inspected by a special person at least once a month for full coverage and shall be recorded, and the [...]
Early warning fire-fighting equipment  In the key parts of the ship according to the environment to install temperature or smoke detector, sound-light alarm device, such as the ship engine room, fixed carbon dioxide room, [...]
Influence of short discharge distance construction on the dredge pump device  As we know, the design flow and design pressure of the single-speed dredge pump on the cutter suction dredger usually correspond to the [...]
Excavate hard clay. Hard clay moisture content is low, cohesive force is large, the cutter rotation is clockwise, in the right transverse movement is easy to produce "hob" phenomenon, in addition to appropriate control of [...]
Selecting dredger appropriately according to construction conditions is an important prerequisite for organizing dredger construction and dredging. If the dredger is not chosen properly, it will not only increase the cost of dredging but also [...]
