From January 10th to February 14th, the Yangtze River Waterway Bureau organized more than
30 engineering vessels and carried out a total of 1,199 dredging of 14 shallow dangerous
waterways, they maintained a dredging volume of more than 1.48 million cubic meters, and
unblocked the "lifeline" of water transportation.
During the dry season of each year, some shallow and dangerous waterways of the Yangtze
River trunk channel will be shallow due to force majeure factors such as water level and
sediment, which will affect the passage capacity of the channel. This year, the Yangtze
River Waterway Bureau deployed large dredging vessels(the vessel has the silt curtains)
including "Changying", "Xipan", "Changshi", "Hangjun" and "Changjing" on 14 shallow
dangerous waterways on the main channel of the Yangtze River over 2,600 kilometers.
The maximum dredging capacity is about 10,000 m3 / h.
