Depth of the Yangtze River Estuary Dredging a new record high

3 re-transmission of the Yangtze River Estuary Dredging good newspaper, the latest mapping shows that the Yangtze River estuary to reach the whole channel slot average depth of 12.01 meters, depth of the tenders the highest level in history were created.

Deep, Jun Eguchi, governance, sand bar is a world-class problem.Faced with this dilemma, the Yangtze River Estuary Channel Authority, the organization of scientific research, design and construction units, draw on collective wisdom to optimize programs to improve construction efficiency.

I Eguchi project from the Secretary for the Ministry of Shanghai Waterway learned, the council invested a total of 17 trailing suction vessel Participation Changjiang Delta 3 Engineering, they make full use of information technology platform "trailing suction hopper dredge monitoring platform V2.0 System" and the Maritime Safety Administration Wusong VTS Control Center integrated command platform, on-site dynamic management of the construction of ships.The ship and sub-periods according to the trend of throwing mud and other features, a daily preparation of construction plans day to day on the progress to ensure completion; the same time, the Yangtze River estuary for the changes in a timely manner to rake the soil characteristics of the first machinery to transform, rationalize the rake head skylights, adjust the wave compensator pressure. The ship according to mapping to find the shallow points, rational layout, trace fat a day project department, project department on a regular basis the data provided by the various ships collation and analysis of timely adjustments to construction methods for the construction of the ship's construction to provide effective guidance.According to mapping with channel depths of water, construction units and common units of reasonable arrangements for supervision of construction section, and timely construction of the ship assigned to the various construction tasks, the construction of the ship in their respective sections within the construction to carry out the construction process optimization, in the construction conditions permit cases, a "downstream dredging," greatly enhance the speed and efficiency of construction of the dredger. Last month, the council 17 trailing suction boat boat reportedly completed a total of 10.11 million cubic meters square, mark the first time monthly output is 10 million cubic meters.

It is understood that construction of the Yangtze River Estuary three regional soil to silt, fine sand-based, run-off loss of trailing suction hopper dredger with an impact on the production efficiency of the important factors. Shanghai Airlines Eguchi project department under the Secretary for the Yangtze River estuary waterway regulation works three characteristics of overflow from the trailing suction loss of the ship start by looking for efficiency and installation of stowage space time, the best combination of improved production efficiency.  Bureau technical staff through measurement and testing, the daily production of the greatest principles for determining the appropriate loading compartment overflow time, take full advantage of the time saved by reducing run-off increase in the number of dredging equipment compartment, thereby to achieve the purpose of raising the ship daily production. According to estimates, click here to carry out the construction process, after a few days ago the most advanced and largest capacity of self-propulsion module trailing suction dredger "Hai-Feng" increase the efficiency of round construction has reached 15%.

 According to reports, the Yangtze River Estuary three works full 92 kilometers. Should the realization of extension of -12.5 m deep-water channel to Nanjing, Nanjing, following more than 10 ports, more than 250 thousand-ton berths will be directly connected to maritime routes, river port will become a harbor, Shanghai "Jianghai transport", "water of transit" advantages can be further enlarge, Shanghai international shipping center will accelerate further.
