At around 15 o'clock on July 6, the water level outside Tuanzhou Ridge was basically flat, and the on-site command was urgently dispatching to carry out a two-way "battle". According to water conservancy experts, the two-way "war" refers to pouring materials into the breach and starting to plug them. Water conservancy experts predict that for the sake of insurance, Helong will need about 100,000 cubic meters of materials.
The reporter saw near the breach that the rescue team was urgently transporting stones, rushing to build wraps and build operating platforms. Zhang Xuanzhuang, director of the safety and environmental protection department of the first engineering bureau of China Aneng Group, said that according to expert opinions, various preparations have been made before the plugging in the early stage, and the plugging operation is currently being carried out, and the project period is expected to be about 4 days.
Liu Guhua, a water conservancy expert at the Yueyang City Water Conservancy Bureau, told reporters that after the start of the plugging operation, the progress of the plugging and rebuilding project will also be accelerated.
Hunan Huarong Tuanzhou Ridge Site: The "second line of defense" reinforcement work is being carried out intensively
At 13 o'clock on July 6, the reporter learned at the scene of the bursting of the Tuanzhou embankment in Huarong County, Hunan Province, that since the collapse of the first-line embankment of the Tuanzhou embankment, the work of reinforcing the "second line of defense" is being carried out intensively.
According to on-site experts, compared with blocking the breach, it is particularly urgent to strengthen the "second line of defense". The work was launched on an emergency basis on the 5th.
The "second line of defense" is the Qiantuanjian embankment, which is about 2 kilometers away from the breach, which is a 14.3-kilometer-long embankment between Tuanzhou and Qiannan, and it is necessary to strengthen this earthen embankment as soon as possible if we want to prevent the flood from continuing to rage and inundating the Qiannan embankment next door.
The reporter saw at the scene that since the afternoon of the 5th, the rescue team has cleared the foundation and removed obstacles and laid colored striped cloth at the foot of the embankment. Experts inspected the embankment back and forth, urging the reinforcement measures to be implemented in strict accordance with technical standards.
According to experts, at noon on the 6th, with the flood water that broke the embankment poured into the embankment, the water retaining surface of the embankment between the Qian Tuanjian became larger and larger, the soil moisture content of the embankment increased, and the danger of leakage and other dangers has appeared one after another, and it may become more dense the day after tomorrow. Therefore, the defense of the "second line of defense" is very important, and it must be reinforced in strict accordance with technical standards, and it must be closely patrolled 24 hours a day, and there must be no negligence.
