Product Details
As previously mentioned, the cutter suction dredger describes an arc round a fixed point, the spud pole or working pole. In many cutter suction dredgers this pole is mounted on a movable carriage, the spud carriage. A second pole, the auxiliary spud, is set out of the centreline, usually on the starboard side of the stern of the pontoon. The type of soil The type of soil to be dredger has a strong influence on the installed cutter head and side winch power, the strength of the ladder, pontoon and spuds. To some degree the type of soil also influences the choice of suction pipe and discharge pipeline diameters. With the same cutting power a cutter suction dredger dredging rock will have a lower production rate than when dredging sand. In view of this, a rock-cutting cutter suction dredger should have pipelines of smaller diameter, because it becomes more economical to pump solids with higher concentrations. With the same production rate it is possible to increase the concentration by reducing the pump flow. Because a minimum velocity is required to transport solids this can only be achieved by reducing the diameter of the pipelines. It must be noted that reduction of the pump flow may lead to a higher percentage of spillage resulting caused by a bad mixture forming-process in the cutter head. The transport distance The transport distance makes demands in relation to the installed sand pump power and the need to load barges. The requirement to load barges is determined by the question of whether the required transport distance is too great to be economically bridged by using a hydraulic pipeline. It is also possible that the use of a hydraulic pipeline is impossible from the point of view of hindrance to navigation. Cutter suction dredgers are seldom equipped to load barges only. If the cutter suction dredger is equipped with an underwater pump, the pump power can be su
