The Yangtze River water level rapid drawdown waterway department invested 13 dredger dredging in Bei ddrtys

The Yangtze River water level rapid drawdown waterway department invested 13 dredger Dredging – Beijing, Beijing, Wuhan, September 12 (Chen Yu Xu Jinbo) reporter 12, from the Three Gorges Reservoir of Yangtze River Waterway Bureau, recently launched the ninth test of water, the Yangtze River water level rapid drawdown. To protect the safety of shipping, the Yangtze River Waterway Bureau deployed 13 dredger stationed in the middle and lower reaches of the shallow waterway risk key expansion dredging maintenance, 10 am, the official start of the ninth test of Three Gorges reservoir, according to the State Flood Control and Drought Relief Headquarters requirements, the reservoir will be at the end of October or November for the water level to 175 meters. With the influence of water storage, and along the Yangtze River in most areas without significant rainfall, the water level of the Yangtze River is continuously fluctuating trend, especially in the middle and lower reaches of the water level decline greatly, many key risks shallow waterway maintenance difficulty increases. According to the Yangtze River Waterway Bureau, the person in charge of the channel, 12, the Yangtze River water level is generally lower than last year’s total of 0.05 meters to 5.27 meters, of which Shashi is lower than last year’s low of 4.55 meters, Chongqing lower than last year. Although the annual dry season before the arrival of the Yangtze River Waterway Bureau will implement dredging construction focus on some shallow waterway risk, but this year the water level is low, resulting in dredging construction for nearly a month ahead of schedule than in the past. At present, the middle reaches of the Yangtze River water level in Shashi continue to ebb, tight taipingkou waterway conditions. Since August, the Yangtze River Waterway Bureau has sent "hang Jun 20", "2 cups" and "Chuck 3" three large dredger in the waterway, the non prohibited manner in the waterway dredging construction, ensure 4 meters waterway maintenance scale, and moving navigation mark 25 in August 22nd, will be too flat navigable waterway from North Branch Intracoastal Waterway changed back to the river channel, improve the navigation conditions. Lujiahe waterway in the middle reaches of the Yangtze River is famous shallow waterway, this year after flood water level falling rapidly, after the Three Gorges reservoir is expected upstream will further reduce the conditions of waterway navigation is not optimistic, since September 6th, the Yangtze River Waterway Bureau organized the "Eagle 3", "Yi Gong mud 503", "Yi Road, drag 801" ground anchor 3 "and other professional construction ships stationed in dredging, the low water level under the condition of ensuring Lujiahe normal navigation. At the same time, the lower reaches of the Yangtze River flood affected by heavy rainfall, severe multiple channel sediment deposition, but the recent recession level rapidly, trough within the sediment is not sufficient to cause erosion, sailing conditions tight, as of press time, the Yangtze River Waterway Bureau has dispatched 9 dredger were stationed north, Funan, Fu Tong East, Nantong and Liuhe the river channel dredging, to ensure safe and smooth channel. In addition, the Yangtze River Waterway Bureau will pay close attention to the recent impact on the middle and lower reaches of the Three Gorges reservoir silt, water conditions, timely grasp around the channel changes, good observation and analysis of the evolution process of water channel, according to the timely adjustment of navigation, ensure the normal sign, bright lights, and sent to the dredger stationed in key shallow waterway risk, to ensure wheel navigation safety. The authorities warned that the impoundment of the Three Gorges Project during the Yangtze river navigation position will be adjusted, the ship should pay close attention to the water level, and the weather channel change, avoid running aground, stranded due to deviate from the route or choose the wrong waters broke down.相关的主题文章:
