Traffic capacity of the three Gorges Dam ship lock limit vessel congestion into normalized | | vessel congestion _ the three Gorges Dam news

　　Yangtze River business newspaper message lock capacity reached its limits, experts say building the second lock, dam, or the necessary

Reporter (reporter Zheng Xing) "thought about the three Gorges Dam, as soon as is a day or two, dam jam has become the norm. "Said one veteran shipping.

A few days ago, Premier Li to again take the Yangtze River Golden waterway in Chongqing to promote construction of the Yangtze River economic belt, driving regional economic growth in covering 600 million people. However, to develop the Yangtze River Golden waterway, had to solve the biggest problem of restricting factors in three Gorges Dam navigation obstruct. Experts said that with the development of the Yangtze River economic belt, breaking the bottleneck in capacity of the Yangtze River, construction of the dam, the second dam and shiplock transhipment may be necessary.

Vessel congestion normalized, navigation capacity limit

"The base is operating at full capacity, in the original design, annual days of normal navigation of TGP's shiplock in about 320 days, and now nearly year-round at 365 days. "A few days ago, the 21st century business Herald quoted Three Gorges Navigation Administration said.

Even so, many shipping and logistics companies are also feeling, movement lag can be a lot of trouble. Said one 30-year Yangtze River shipping, a senior, three Gorges Dam jam is now the norm, and currently ships on the Yangtze River, to think about the three Gorges Dam, wait one or two days is normal.

If you have a special weather, vessels of the three Gorges dam will also accumulate will usually wait for 3-5 days before the dam. Case of shiplock, even 7-10 days to cross on the three Gorges Dam. Boatman said long-term operation of freight transport, ships in their business last year, the three Gorges Dam, the average wait time, amounting to more than 30 hours.

These parties, design of TGP's shiplock capacity for one-way traffic of 50 million tonnes a year, "and we had planned was to maintain the navigation capability to 2030, but the current traffic demand far beyond what we expected. "This means that the current capacity of three gorges ship lock, already in 2013, near its design capacity.

　Expert: to build dams and sluice transit or can coexist

It is understood that aiming at the three Gorges Dam navigation obstruct issues industry there are two main kinds of advocates, is opening new channel of three gorges waterway, advancing the construction of the second ship lock of the three gorges. The second is to create the "dam".

"Neither assertion can have its own advantages. "Qin Zunwen, Deputy Director of Hubei Provincial Academy of social sciences said the dam has the advantage of a short time, and now our waiting gate has normalized, 35 days. To this end, the building of Yichang city "over dams industrial park" in 2010, started second lock has not been phases, played a very important role.

However, from a cost perspective, many people in the shipping and logistics company said, "I'm a ship over more than 500 containers, need to have dozens of hundreds of trucks to transport, a 40-foot (big box) box, dam cost 1500 to 2000 Yuan, a boat-load of 500,000 to 600,000 yuan, if the lock directly, it is almost zero cost. ”

"The construction of the second ship lock will once and for all solve the problem of traffic demand, still needs time to test. With the development of the Yangtze River economic belt, the construction of secondary dam and lock industries may be necessary. "Statue of Qin said.

三峡大坝船闸通行能力达极限 船只拥堵成常态化|三峡大坝|船只拥堵_新闻资讯

　　长江商报消息 船闸通行能力达极限，专家称建第二船闸、翻坝或都必要

　　本报讯(记者郑星)“想过三峡大坝，一等就是一两天，过坝拥堵的现象已成常态化。”一位资深航运人士表示。

　　日前，国务院总理李克强在重庆重提借长江黄金水道推动长江经济带建设，推动涵盖6亿人口的区域经济增长。不过，要想发展长江黄金水道，首先得解决目前最大的制约因素三峡大坝碍航的问题。专家表示，随着长江经济带的发展，要突破长江运力瓶颈，修建大坝第二船闸和翻坝转运或许都是有必要的。

　　船只拥堵常态化，通航能力达极限

　　“基本是满负荷运营，原设计中，三峡船闸每年的正常通航天数在320天左右，而现在几乎维持在365天全年运行。” 日前，《21世纪经济报道》引述三峡通航管理部门相关人士表示。

　　即使如此，不少船运物流企业还是感慨，通行量滞后给企业带来了不少麻烦。一位已从事30年长江航运的资深人士表示，现在三峡大坝的拥堵已经是常态化了，目前长江上的船只，要想过三峡大坝，等一两天是正常现象。

　　如果遇到特殊天气，过三峡大坝的船只还会堆积，一般就会在坝前等候3至5天。如果遇上船闸检修，甚至会等上7至10天才能翻过三峡大坝。有长期经营货运的船家表示，其所在企业的船舶去年过三峡大坝的平均等待时间，约达30多个小时。

　　上述管理人士介绍，三峡船闸设计通行能力为每年单向通行5000万吨，“而这个通航能力我们原计划是维持到2030年，但目前的通航需求量远远超出我们的预计。”这意味着三峡船闸目前的通行能力，已经在2013年接近其设计运力。

　　专家：修建二闸和翻坝转运或可共存

　　据了解，针对目前三峡大坝碍航问题，业内人士介绍主要有两种主张，一是开辟三峡水运新通道，推进三峡第二船闸的建设。第二种则是打造“翻坝”产业。

　　“两种主张都有自己的优势。”湖北省社会科学院副院长秦尊文表示，翻坝的优势在于时间短，而现在船舶候闸已经常态化，动辄三五天时间。为此，宜昌市打造“翻坝产业园”于2010年就开始动工，在第二船闸尚未成型的阶段，起到了很重要的作用。

　　不过，从成本方面考虑，不少航运物流企业人士表示，“我一艘船有500多个集装箱，需要有几十上百辆卡车来转运，一个40呎(大箱)的箱子，翻坝成本是1500元至2000元，一船合50万元至60万元，如果直接走船闸，则几乎是零成本。”

　　“修建第二船闸能否一劳永逸解决通航需求量的问题，还需要时间去检验。随着长江经济带的发展，修建二闸和翻坝产业或许都是有必要的。”秦尊文说。
