Where are the three interceptions of the Yangtze River? The Yangtze River has been broken several ti

In addition to the diversion of the open channel, the second interception of the Three Gorges Project in November 2002, a total of three interceptions were carried out on the main stream of the Yangtze River.

The first interception was carried out for the construction of the Gezhouba Junction Project on the Yangtze River. The interception was on January 3, 1981. The width of the Longkou interception is meters, the actual flow rate of the Longkou interception is 4190 to 4720 cubic meters per second, the maximum drop is meters, the maximum flow rate is meters per second, and the interception lasts for hours.

The second interception was the interception of the Great River by the Three Gorges Project. The interception was completed on November 8, 1997. The width of the Longkou interception is 40 meters, the actual flow rate of the Longkou interception is 8480 cubic meters per second, the maximum drop is meters, the maximum flow rate is 3 meters per second, and the interception and throwing lasted 29 hours.

The third interception was the second interception of the Three Gorges in November 2002. This interception will be carried out on the diversion nullah. The interception was completed on November 6, 2002.

The width of the Longkou is 150 meters in the upstream and 140 meters in the downstream, and the interception flow is designed to be 10,000 cubic meters per second, the maximum drop of the Longkou is 10 meters, and the maximum flow rate is 10 meters per second.

According to water conservancy experts, the drop, flow rate and flow rate of the interception dragon are important factors that determine the difficulty of interception. The larger the interception drop, the larger the flow rate and the higher the flow velocity, the greater the difficulty of interception.

All three of these interceptions on the Yangtze River were carried out by the China Gezhouba Group.

On November 8, 1997, the Three Gorges Project achieved its first interception of the flow of the Three Gorges Project, and the construction of a 16-kilometer-long dam on the left bank and a power plant building in the pit formed by the cofferdam was built. The other section of the Three Gorges Dam, which is about 0.9 km long, will be built in the pit formed by the cofferdam after the secondary interception.

The first time happened in the Yuan Dynasty in 1342, it is said that this time the river dried up directly, and the relevant records only recorded: "July storm, the river **, as high as four or five zhang, people and animals drowned countless ......."The Yangtze River dried up overnight. "The other time happened in 1954, in Taixing City, Taizhou City, Jiangsu Province.

The analysis of the possibility of two interruptions of the Yangtze River is analyzed from the seasonal and geographical environment, the time of the interruption occurs around the eighth month of the lunar calendar, the flow of the river is abnormal, and when it flows through the Taixing section, due to the abnormal flow of the river, and the flow direction of this section of the Yangtze River is north-south, the phenomenon of diversion occurs, and the flow into other tributaries leads to the occurrence of downstream interruption.

The Yangtze River severance incident is real.

As the third largest river in the world, who would believe that our mother river, the Yangtze River, would have broken down? Moreover, the location of the Yangtze River is not a place with little rain and more drought.

As the largest river in China, its length, flow and coverage area of the entire basin are the first in the country. No one in China believes that the Yangtze River will stop flowing, because if you look at the water in the water, you can't imagine how long it will take for it to dry up or stop flowing.

Analysis of the causes of the Yangtze River outage

But in history, believe it or not, the Yangtze River did break its flow twice, once in ancient times and once in the 50s of the 20th century. Many people believe that there are very few records of the Yangtze River breaking in ancient times, so the credibility is very low. However, judging from the interruption of the Yangtze River in the 50s of the 20th century, it is entirely possible that the flow will be broken in ancient times.

In fact, the situation of the Yangtze River breaking is completely different from that of other rivers. Other rivers are cut off mainly because of a lack of water supply, and then the water level slowly drops, eventually causing the flow to stop. The Yangtze River broke off suddenly, coming and going as fast as it came.

In fact, the record of the first interruption of the flow in ancient times was during the Yuan Dynasty.

The second interruption occurred in 1954, both times in the Taixing section of Jiangsu. The Yangtze River suddenly dried up overnight, which is completely different from an ordinary cut off the flow. Ordinary rivers are cut off because the water supply is slow or not available and they dry up slowly.

Unlike the Yangtze River, which also rolls eastward during the day, it suddenly stops the next day after one night. It's strange that it happened twice in the same place.

The so-called Yangtze River interception refers to temporary measures taken to build dams, such as the Three Gorges Dam.

The construction is a patent with the original Jiangxin Island (it seems to be called a genus.

Zhongbao Island), where the Yangtze River is naturally divided into two sections, north and south. The so-called river damming is simply to cut off one section of the Yangtze River, then build temporary dams on both sides, and then drain the water between the two dams, so that a dam can be built at the bottom of the riverbed, while the Yangtze River water can still flow downstream from the other side of the river. When this side is repaired, the temporary dam body will be demolished and the Yangtze River water will flow through the outlet of the dam that has been repaired.

Then cut off the other side of the river and repeat the above work to build a complete dam. This is basically the case for dams built over wide rivers, such as Gezhouba.

Winter is the dry season, and the amount of water is small, and it is easy to intercept the flow.

9 In early November, the rainfall in the upper reaches of the Yangtze River and above Yichang was recorded.

Except for mid-October, which was slightly heavier, the rainfall in the rest of the decade was lower than normal. In early September, the rainfall in the upper reaches of the Yangtze River was less than 7 percent; In mid-September, the rainfall was less than 2 percent; In late September, the rainfall was less than 1 percent; In early October, the rainfall was less than 1 percent; In mid-October, the rainfall was more than 3 percent; In late October, the rainfall was less than 2 percent; In early November, the rainfall was less than 6%. The average flow in Yichang in September and November was below the average value of the previous year, and the average flow in late September and mid-October was the driest since the beginning of the record in 1890, and the average flow in early November was the average in the interception period.

Unraveling the mystery of the Yangtze River's disconnection, what caused the Yangtze River to be broken?

I haven't heard of it, but it depends on which paragraph.

Some. There are two short interruptions of the Yangtze River in history: one is in August of the second year of the Yuan Dynasty (1342 AD), the navigable section of the river in Taixing County, Jiangsu Province suddenly dried up overnight, and the residents along the river went down to the river to pick up the relics in the river.

The next day, the river tide suddenly came, and many people drowned.

Another time was at about 4 o'clock in the afternoon of January 13, 1954, this strange phenomenon appeared again in Taixing County, Jiangsu. On the same day, the sky was pale and yellow, the river suddenly stopped, and the ship ran aground. More than two hours later, the river suddenly rushed down.

When people heard the sound of the water, they rushed to the shore, but fortunately there were no injuries.

No. Because the Yangtze River basin has a large area and many tributaries, there is always rainfall in the basin, and there will be no interruption of flow.

Appears twice.

In 1342 A.D., Taixing County, Jiangsu Province (now Taixing City) and at 4 p.m. on January 13, 1954, it was also in Taixing City.

There should be none, there is a lot of rainfall along the Yangtze River every year.

According to historical records, the Taixing section of Jiangsu Province in the lower reaches of the Yangtze River has been interrupted twice.

The first interruption was in August of the second year of the Yuan Dynasty (1342 AD) 655 years ago. At that time, it was the flood season of the Yangtze River, and the residents along the river in Taixing were surprised to find that the Yangtze River was exhausted overnight, and people went down to the river to pick up the relics in the river. The next day, the tide suddenly came, and many people were swept away by the rushing river because they could not escape.

Another time. At about 4 o'clock in the afternoon of January 13, 1954, the wind and sand along the Yangtze River in Taixing suddenly rose, the sky was pale and yellow, and suddenly, the river was suddenly surging and surging, dozens of ships ran aground, and the bottom of the river appeared in front of people's eyes. After more than two hours, the river suddenly rushed down again, and the sound of the water was like thunder.

The people who were in the river rushed to the shore when they heard the sound, but fortunately no one was swept away by the water.
