- Q:Who knows what's the name of the biggest dredger in China?
- Shanghai Waterway Bureau trailingsuction ship strength slightly, most of its name to "Xinhai" at the beginning, the Phoenix as the representative of the Xinhai tank volume is about 16000m the ship should be fand the largest and most advanced tshd. To say that the largest is the new sea lion, but the head is large, inefficient, difficult to enter the stream.
- Q:Does dredging dredger need relevant qualification?
- But if the local government regulations must be legitimate formal dredging project, estimated to need to apply for a ship's certificate, it is equivalent to a person's identity card! If you need Qingzhou Wynn mine, you can go through the whole process, the relevant costs to consult manufacturers.
- Q:What are the crew members on the dredge?
- But in general, the dredger crew responsible for the work can be divided into: navigation, communication and work positioning on the ship, electrician, turbine, maintenance, and operation personnel (dredging) and special equipment (such as grab dredger crane and grab operation, cutter suction, suction dredger winch, water pump operation etc.).
- Q:The famous type of cutter suction dredger
- The famous famous suction dredger is China's sky whale, (Tianjin River Navigation Bureau), sky Navigation Bureau, 5000kW and so on. At present, the world's largest is Luxemburg, Jan, De, Nul dredging group JDN8069.
- Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
- TSHD is installed through the chain of dredge bucket will be dug out of the bottom mud, stored on a ship or barge dredger edges.
- Q:Who has the construction plan of dredger dredger after dredger dredging and dredging with dredger barge?
- Would dig into the mud barge, barge by suction dredger, using force pump suction dredger through pipelines on shore
- Q:What is the working principle of a cutter suction dredger?
- Construction principle of cutter suction dredger:The dredger is in place, the steel pile excavation construction method, horizontal positioning dredging and filling, it is with a fall in the channel center line of the main hull positioning pile as the center of the rotation, the role of the reamer for traversing on lateral swing in the channel width, the construction method of excavation section of soil layer cutting cutter.
- Q:3800m3 cutter suction dredger
- Should be the hour efficiency of 3800 cubic meters, 3800 cubic meters of water or flow, I feel your problems are wrong, some 3800 type dredger, Holland IHC company, but refers to the total installed power. So I think it is type 3800, not 3800M3.
- Q:The working principle of a trailing suction dredger
- The ship is equipped with one or several sets of centrifugal pumps, centrifugal pumps for absorbing water and mud from the bottom of the vessel, into the mud tank. These operations are carried out on the voyage, while air while digging, mud tank fill to throw mud mud area, through the Bilge mud. Handle cases
- Q:Advantages and disadvantages of trailing suction dredger for trailing suction dredger
- In dredging, sediment laden with large amounts of water is transported to the dumping area, thereby affecting production. The suction boat can be used in infrastructure dredging and maintenance dredging, but not in narrow water areas
