The Three Gorges Ship Lock Opens a Green Channel for Boats

At 8 o'clock on the July 31st, the Three Gorges Navigation Authority reduced the flow of the Three Gorges project to 25,000 cubic meters per second in accordance with Changjiang Defense's No. 29 dispatch order. The Three Gorges Navigation Administration affected hundreds of ships to be gated between the two dams. The low-power ships opened a "green channel", and during the interval of the flood peaks, 203 ships were rushed on the first day.

Since the Three Gorges Project's storage flow exceeded 30,000 cubic meters per second on July 9th, successive rounds of catastrophic floods hit the Three Gorges, causing the Three Gorges ship lock to stop at two degrees. The discharge flow from the Three Gorges Project has been from 40000 cubic meters per second to 30000 cubic meters per second. Dispatch, most small power ships with power below 270 kilowatts cannot pass the gate. The number of stern vessels in the Three Gorges Dam area reached 514 for a long time, and the median length of the lag tanks was 24 days.

In order to help these ships staggering due to heavy traffic to pass through the Three Gorges Dam smoothly, the Three Gorges Navigation Administration, the National Defense Corporation, and the Yangtze River Defense Center have made various efforts. Finally, on the occasion of a slight decrease in traffic on July 30, the total number of Yangtze River Considering the need for flood prevention and navigation, a scheduling order number 29 was issued.

In order to make good use of this difficult-to-control leak time, the Command Center of the Three Gorges Navigation Administration elaborated a seamless overpass sluice plan between the two dams. The time between the Three Gorges Ship Lock Gates was optimized to 90 minutes, and one sluice rated load was taken. Reached 11 ships. After a whole day of intensive evacuation, by 20:00 on July 31, 203 small-power boats had passed through the Three Gorges ship lock safely. At present, the discharge flow of the Three Gorges is still 25,000 cubic meters per second, and emergency evacuation operations continue. It is estimated that by 8 o'clock on August 2, the Three Gorges dam area backlog will be fully cleared.
