Product Description

The Bucket Dredger is one of the mechanical dredgers. A bucket Dredger is a stationary dredger that is equipped with a continuous chain of buckets, which are carried through a structure, the ladder . This ladder is mounted in a U-shaped pontoon. The drive of the bucket chain is on the upper side. The bucket dredger is anchored on six anchors.

The design of Bucket Dredger
When designing bucket dredgers the following design parameters are important:
• Production capacity
• Dredging depth (minimum and maximum)
• Soil type
• The discharge of the dredged material (barges or via pipeline)
As previously mentioned, the bucket dredger can be used in all types of soil from clay to soft rock which has not been blasted and hard rock which has been fragmented by blasting. The type of soil to be dredged has a big influence on the design and the construction of the dredger. Considerable forces arise during the dredging of rock. For all types of soil it is necessary to know the required cutting capacity and the energy that is needed to transport the dredged material via the bucket chain to the upper tumbler.

Essentials of construction process control
Excavation method
1, when the construction area conditions, is not affected by the width of cut dredger and edge water depth limit, should adopt oblique cross cut construction method.
2, the narrow channel, channel depth is less than the dredger draught, should adopt fan-shaped horizontal excavation construction method.
Layered construction
1, when the dredging area of mud layer is too thick, soft clay layer thickness of more than 2~3 times of high mud bucket, sand and hard soil and mud layer thickness of more than 1~2 times the bucket high, should be stratified excavation. The thickness of the layer is generally used 1~2 times higher than the height of the visible soil.
The concurrent and countercurrent construction
Chain bucket dredger is suitable for current construction. Only in the construction conditions or by limited construction is downstream fluctuation trend under the condition of downstream construction should be used when the stern mooring ship forward main control.
