Difficulty in dredging hard plastic soil For non-inertia grab, the construction efficiency of hard plastic soil is not reduced to a great extent, But for the cutter suction, bucket wheel and inertia grab dredger, excavation and [...]
1.1Wear of dredging equipment pipeline： Wear is closely related to the movement of soil particles, especially the falling speed of soil particles in pipelines. Therefore, it is necessary to study the wear of dredger, pipe and mud [...]
The cutter suction dredger plays an important role in the construction of channel dredging and sea reclamation. Dredger's mud pump as the core component of cutter suction dredger, its high efficiency, the stable operation directly [...]
The cutter suction dredger and the boost pump boat work in series. The determination of the position of the boost pump boat is the key factor to improve the production efficiency.Under the long discharge distance, Using boost pump for conveying [...]
The clayey soil containing calcareous nodules has unique characteristics of pipeline hydraulic transportation. In order to avoid pipeline blockage, effective engineering and technical measures can be adopted by CSD. 1) When using high-concentration mud pipeline [...]
The spud system is one of the main equipment of the cutter suction dredger. It will guarantee the accurate positioning of the dredger operation, by working together with the swing winch and anchor rope system [...]
There are two types of winch for modern cutter suction dredger, electric drive type, and hydraulic drive type. The hydraulic drive winch has two types, open-gear transmission hydraulic winch, and the planetary reducer hydraulic winch. [...]
Recently, Hansel QC engineers carried out the factory acceptance testing of Cutter Teeth for our CSD newbuilding project. Hansel has established a full set of quality control system covering each procedure of our product, [...]
Before cutting soil , we have to distinguish the difference between clay soil and non-clay soil: the way of breaking is different and requires a lot of practical experience. Clay soil: It has adsorption [...]
When using spuds construction, after the dredger is towed to the starting point of the channeling, the tug-boat should be decelerated and stopped. After the ship's speed is eliminated, put down the spuds and set [...]
