Through the practice of dredging engineering of river, river and sea, the characteristics and shortcomings of the cutter-suction dredger are understood to a certain extent. The following experience in its application is described as follows:
(1) The cutter suction dredger has a wide range of USES. It can be used in rivers, lakes and seas for dredging, channel excavation and land reclamation. Under special circumstances, high-power reamer equipment can be installed on the cutter suction dredger to excavate the rock stratum such as basalt and limestone.
(2) Cutter-suction dredger has high efficiency, large output and long pump distance. Large cutter-suction dredger can flow up to thousands of cubic meters per hour; The sediment or rock crushing material is pumped to a distance of 1,000 meters by means of a mud pump and a mud discharge line under strong power.
(3) Cutter suction dredger is simple to operate and easy to control. The dredger relies on the stern carriage of the ship to position and step the steel pile, USES the two measuring cables of the reamer jib and the anchor fixed in the trench, is pulled by the reamer, the two wagons swing to cut the silt material, works under a certain control pendulum Angle, and pumps the stranded material to the accumulation yard through the slurry pipeline. The stepping of a dredger is made up of two piles moving alternately, stepping forward.
(4) The large cutter suction dredger is equipped with self-propelled system. The migration can be self-propelled into place. Most small and medium-sized dredgers have no self-propelled system and are towed by tugboats. Small and medium-sized dredgers can be designed and built into a package, transported to the site by land, after assembly can be used. (5) Good economy of cutter-suction dredger. Material excavation and transport of a one-time completion, do not need other ships to cooperate, several handling. Relative engineering cost is lower.
