Recently, the Ying 3 fleet, the director of Yichang Waterway Engineering, entered the construction
area in an orderly manner to carry out dredging of the Zhijiang Waterway.
Affected by the flood season, the upstream brought a large amount of sediment to silt up part of
the channel, which brought certain hidden dangers to the navigation of ships. At the same time,
the Three Gorges Dam is in the impoundment period, The dredging should be carried out as
soon as possible. It need carried dredgers and silt curtains for waterway dredging. At the
same time, the construction area is close to the waterway and the risk factor is high,
which brings certain difficulties to the construction.
