What is the biggest difficulty in the plugging of a polder breach in Poyang within 5 days?

Poyang County, located in the northeast of Jiangxi Province and on the east bank of Poyang Lake, was hit by continuous heavy rainfall, and the water level in the Changjiang River basin was rapidly **, resulting in flooding in many places such as Wengui Daowei, Zhongzhou Wei and Guihu Village in Poyang County, and 6 villages and more than 10,000 acres of cultivated land were flooded, and nearly 10,000 people were evacuated urgently.

In Guihu Village, Poyang County, after fighting overnight, an 80-meter-long breach was successfully closed at around 11:30 noon on the 15th.

At 23:08 on July 13, after the first victory of the Guidao polder, a total of more than 400 people from the three directions of Nanchang, Changzhou and Xiamen of the Second Engineering Bureau of China Aneng (formerly known as the China Armed Police Hydropower Force) blocked other polder breaches. At 11:38 on the 15th, as the bulldozer pushed the last load of stone to the water, the 80-meter breach in Guihu Village was successfully closed; At 18 o'clock in the afternoon of the 15th, the 40-meter breach of Dengfang Village upstream of the polder embankment of Wengui Road was successfully closed; At present, the task of sealing the 180-meter breach in Zhongzhouwei is advancing rapidly.

In order to ensure that the tough battle of flood control, rescue and disaster relief is won, and to reflect the rescue and disaster relief work of cities along the Yangtze River after the flood peak, Shaanxi News special reporters Huang Ting and Zhang Feng went to Jiangxi on July 15 to focus on the latest, fastest and most authoritative flood response information in the Yangtze River Basin, and witness the Yangtze River flood control and defense battle.

During the interview, I learned that China Jiangxi Network and Information ** carried out a large-scale public welfare plan of "Love Caravan" and raised materials to provide assistance to the severely affected cities and counties in the province, which fully demonstrated the social responsibility and responsibility of the mainstream, so I also came to participate in and witness this theme public welfare activity. We also hope that through interviews and reports on this event, we will have an in-depth understanding of the disaster situation and urgently needed items in the affected cities and counties on the shores of Poyang Lake, transmit accurate information back to Shaanxi, and call on the people of Shaanxi and caring enterprises to provide accurate support and help to the affected people in Jiangxi. Huang Ting is looking forward to focusing on his peers this time.

This morning, they set off again and together with the relevant departments in Jiangxi to deliver relief materials to the affected people.

The Wengui Road polder breach in Poyang County, Jiangxi Province, was as long as 120 meters, and 15,000 acres of land were flooded. Since the upstream section has been washed away by floods, the biggest problem in completing the plugging within 5 days is that it cannot be carried out in both directions.

The inability to construct in both directions is the biggest difficulty. Only one-way construction will cause the construction period to be extended, and if the time is extended, there are too many factors that cannot be improved.

The main reason is that the operating conditions at the rescue site are not optimistic, the roads are not usual, large heavyweight vehicles cannot pass, the embankment is too narrow and it is not conducive to blocking, and it is a hot weather.

1. The flood is too large, so that the workload of the staff is large, the difficulty is also great, and the danger at the critical moment is also great.

2. If the flood is too large, the collapse will be large, and the rain will be widespread in the past few days, and the number of people is not enough.

As of August 2020, it has been blocked.

At a critical moment in flood control, Jiangxi has upgraded the second-level emergency response for flood control to the first-level, and some people in Jiangzhou Town have begun to evacuate in an orderly manner. In addition to plugging the embankments that have been in danger, the local government also actively uses single retreat polders and flood storage to ensure the safety of Poyang Lake as a whole during the flood season.

At 11 a.m. on July 12, the water level of Poyang Lake Xingzi Station reached meters, which was meters higher than the highest water level in history in 1998, and the water level is still continuing**. The Xingzi station of Poyang Lake is the main hydrological station in the Poyang Lake basin, which means that the entire Poyang Lake basin has experienced the highest water level in history.

It is estimated that 5-6 days can block all the breaches, and now the firefighters have worked very hard, hoping to succeed as soon as possible!

It is estimated that in 5-6 days, Poyang Lake will be blocked, and 40 trucks of stones will be required for every meter of advancement, and the flood control work is urgent, but it is believed that the breach will be blocked soon.

Poyang Lake breach blocking, every meter to advance 40 cars of stones, flood control work has been urgent, but it is believed that the breach will be able to be blocked soon.
