What are the characteristics of cutter suction dredger

Cutter suction dredger has good performance

(1) Cutter suction dredgers are widely used and can be used in rivers, lakes and seas for dredging, channel excavation, and land reclamation. In special cases, the cutter suction dredger is equipped with high-power (referring to the amount of work done by the object in unit time) reamer equipment, and rocks such as basalt and limestone can be excavated without blasting (composition: solid minerals or minerals) mixture) ground.

(2) The cutter suction dredger has high working efficiency, large output and long pump distance. The output of large cutter suction dredgers can reach several thousand cubic meters per hour; relying on powerful power, the sediment or broken rock materials can be pumped thousands of meters away through mud pumps and mud discharge pipelines.

(3) The cutter suction dredger is easy to operate and easy to control. The dredger relies on the trolley at the stern to position and step the steel piles, uses the two steel cables on the reamer arm frame and the anchor fixed on the two sides of the excavation groove, is pulled by the winch, and the two compartments swing and cut the sediment materials. Working under a certain controlled swing angle, the twisted material is pumped to the accumulation yard through the mud pipe. The stepping of the dredger is to move forward alternately by two piles.

(4) The large cutter suction dredger has a self-propelled system. It can be self-propelled in place during migration. Most of the small and medium dredgers have no self-propelled system and are towed by tugboats. Small and medium-sized dredgers can be designed and built into assemblies, transported to the site by land, and can be used after assembly.

(5) The cutter suction dredger is economical. The excavation and transportation of materials are completed at one time, without the cooperation of other ships, and several times of transportation. Relatively low engineering cost.
