Actually, it's not. On most world shipping charts, Nanjing Port is indeed marked as a seaport. This is really no exaggeration. Nanjing Port is a major coastal port, a major hub port and a first-class port open to the outside world in China. The most important thing is that it is the deepest international deep-water seaport inland.
In 2020, the throughput of China port will be in the top ten, Suzhou port will be the sixth, Zhenjiang port will be the tenth, and the rest will be seaports. Why are there only a dozen Nanjing ports? Because the upstream of Zhenjiang Port is close to Yin, it is a notoriously dangerous section of the Yangtze River.
The difficulty of yin:
1, two right-angle turns.
The current pushes the boat north and south, which is difficult to control.
3. The density of ships is 2500-5000 ships/day, which is the entrance of the Beijing-Hangzhou Canal.
The most important thing is that the waterway is narrow and 230 meters wide.
5, the river is complex, fishing, ferry.
6. It is often foggy.
It can be seen that the upper reaches of Yin River are difficult places for seagoing ships to enter. Even so, in the first half of 20021,75,000 tons of ships arrived in Nanjing Port, setting a record high. With the construction of Yingongzhou Waterway, Nanjing Port has great expansion potential in the future.
The Yangtze River-12.5m deep-water waterway extends to Nanjing, where 50,000-ton ships can reach Nanjing all day, and 65,438+10,000-ton ships can reach Nanjing by tide. The Jiangsu section below Nanjing has become a 400km seaport area, which is why Nanjing Port is a seaport.
Nanjing Port is mainly located in the downstream of the Second Bridge. The clearance height of the fourth bridge is 50 meters. Like the second bridge, it is 24 meters. About 17 bridges on the Yangtze River are all 24 meters long. Many people mistakenly think that the height of the bridge is limited, so Nanjing Port should be under the Second Bridge.
This is not the main reason, but the more important reason is that the upper reaches of the Second Bridge, such as Yanziji, are shallow in water. The biggest problem of Yangtze River shipping is not height. It is very easy to reduce the height of a ship, and the most difficult thing is the depth. The construction of12.5m waterway under Nanjing of the Yangtze River is a great and magnificent project, which has played a great role. For example, among the top 20 ports in China, Jiangsu usually has 6-8 ports. This project, from Nanjing to Nantong, needs strong financial strength and coordination ability to operate well, and Jiangsu Province has indeed done it.
Thirty years ago, the waterway of the Mississippi River, more than 200 kilometers below Batuluge, reached 13.72 meters. The federal parliament approved the expansion to15m, and the long-term18m.
Suez Canal, 190 km, is also quite far from the waterway below Nanjing. The depth mainly depends on two canals (Panama and Suez), so we will follow. Recently, the Suez Canal Authority began dredging the southern section of the canal, and the maximum depth was deepened from about 20 meters to about 22 meters. In other words, according to the changes in the international shipping market, Jiangsu can dig deeper waterways by camera.
At present, the follow-up improvement of 12.5m waterway is still in progress. With the expansion of scale and the improvement of demand, the next promotion plan will definitely be comprehensively considered according to the future situation.
