The cutter suction barge is a kind of sand-collecting equipment that relies on reamer to cut and break the riverbed, and then extract the sand by pumping the river. The use of twisted-suction barge is widely used in rivers. In addition to the drainage of the river sand suction barge, can also be used for waterway dredging, waterway excavation, blowing and filling and so on. In special case, the cutter suction dredger installs high-power reamer equipment, and can excavate basalt and limestone rocks without blasting.
The working efficiency of the cutter suction dredger is high, the large cutter suction dredge can reach thousands of cubic meters per hour, which greatly improves the yield of river sand. The pumping distance of the cutter suction barge is far away, it can rely on the silt or debris material to power through the mud pump and the drainage pipeline, pumping out thousands of meters away.
The operation of the twisted-suction barge is simple and easy to control. The pumping vessel relies on the stern car of the ship to position and advance the steel pile. Using the Reamer bridge arm lateral shifting wire rope and the connection fixed to the digging groove two measured anchor, relying on the hinge car traction, by swinging around the control pendulum angle, the cutter or bucket wheel after digging the silt, after transporting the mud pipe pump to the designated area. The advance of a pumping vessel is alternating by two piles and moves forward.
Large-sized twisted-suction barge with a self-navigation system. The fields can be in place. Small and medium-sized sand pumping vessels are not self-navigation system, dragging rows by tugs. Small and medium-sized pumping vessels can be designed and constructed to assemble, transported by land to the site, after assembly can be used. The economical nature of the wring-suction barge. River sand excavation and transportation can be completed one-time, no other ships need to cooperate with many times, relatively low cost.
