Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
Extend the straw to the bottom of the water, turn on the mixer, and stir up the mud at the bottom of the water. Then suck the mud out of the pipe and send it to the site by the pipe.
Q:Who knows what's the name of the biggest dredger in China?
Tianjin Waterway Bureau of the pumping strength slightly stronger its name to "day" at the beginning of the word, is the largest dredger and Tianqi Tianlin, nominal production in my impression is 4200m /h fand the two sister ship, is currently the largest dredger.
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:Does dredging dredger need relevant qualification?
I can do it for you or not! No, oh, no!
Q:What is the working principle of a cutter suction dredger?
To locate the pile as the center circle movement by sliding around the hull swing cutter knife and realize dynamic soil, can pump to thousands of meters away
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:Classification of trailing suction dredgers for trailing suction dredger
Trailing suction dredger is one of suction suction type. It sucks in mud by raking the head of the two side of the ship's hull or at the tail to work with mud and side navigation. Is the use of mud rake scarification, boat design sediment tank, tank volume said the size of the ship. A single to rake or harrow, are arranged on the ship or on both sides. Suction dredger is flexible, high efficiency, strong wind waves, suitable for coastal ports, the wide river and ship anchorage operation in large waves and without the cover of coastal and estuarine areas, should choose the self-propelled trailing suction dredger. Soil works suitable for loosening and less than clay hardness. The self-propelled boat is equipped with a mobile power unit (paddle machine) to drive the dredger.
Q:Advantages and disadvantages of trailing suction dredger for trailing suction dredger
Therefore, the utility model is very suitable for the construction of canals and canals in ports or navigable ships. The disadvantage of a trailing suction dredger is that the bottom of the dredger is hard to dig
Q:Who has the construction plan of dredger dredger after dredger dredging and dredging with dredger barge?
Is it a filling scheme for dredger? How about a suction dredger on the side of Qingzhou? Customer feedback is also OK, you can come and have a lookSpecific contact, see user name, basic data
Q:3800m3 cutter suction dredger
3800m3 bucket wheel dredger is at the end of the last century according to the Ministry of transportation "based on domestic design and construction, the introduction of equipment key technology policy, the Yangtze River Waterway Bureau presided over the development of construction, Shanghai 708 Institute of design, Wuchang shipyard built China's first inland new dredger. The ship's key power equipment, dredging equipment, hydraulic systems were provided by German SKL company, United States Ellicotte (Aili, Kurt) company, the United States Dennison hydraulic company. This ship has been officially delivered to the Yichang Waterway Engineering Bureau of the Yangtze River. The name of vessel is No. 1.Bucket wheel cutting device in the river near the mouth of the soil suction, and by rotating the bucket wheel by cutting soil and water into high concentration mud, directly transported to the suction suction head of the top tube, rely on the suction centrifugal pump, the suction pipe has certain vacuum. The mud suction head, suction tube at the top end of the suction pipe, through the mud pump pressure after the mud through the mud discharging pipe into the mud barge or transported to the mud field. Through positioning piles, positioning piles, landing gear and traversing winch, the positioning of dredger, longitudinal forward movement and lateral swing of ship are achieved, and the purpose of continuous excavation of river bed soil is achieved.
