On 8 june, the baccalaureate entered the second day. Like the children, there is a high degree of concentration, and there are dispatchers at the long sand reservoir。
As of 1 june, changsha officially entered the main phase. During the rainy season, the onset of disasters and the critical period of resistance, a major test of disaster prevention and mitigation is being conducted in this mountain water city。
From precision warning to early transfer, from science to hard nuclear technology, changsha's combination of fists contains a “safe code”。
519 reservoirs, changshaProtection“water safety guard”. How do they work together
In the early morning hours of 8 june, lights were lit at the dispatch centre of the yangtze bridge reservoir。
"stop a large crew and keep two stations running!" the watchman gave a decisive order to keep an eye on the screen。
Taking into account the saturation of the soil in the storage area, which makes it very easy to overwhelm the water level by heavy rainfall, a tree bridge reservoir was restructured in early june and three generators were fully operational. This is the basis for the operation of this round of rainfall, which is “suspension and trenching”。
On the other side, the yellowwood reservoir hydroelectric plant in ningzhou is also “actively thin”。
In addition, there are 59 small reservoirs in changsha (1 in sunyang and 58 in ning township) that are involved in the scientific movement “pre-rain pre-dumping reservoir to stop the flood peak in the rain”。
According to statistics, during heavy rainfall during this round, the city-wide reservoir stock climbed from 960 million cubic metres to 1,019 million cubic metres, a net increase of 59 million cubic metres。
Every drop of this increase is a “calculated” redundancy and a drought-resistant reserve。
That's right. The "dry and flood surge" is a classic hunan roll. The scientific movement of reservoirs is also a valuable source of water for the subsequent possible drought, achieving a “win-win” between flood security and water storage。
Heavy rainfall is not just a flood, but can also cause a collapse, landslides, mudslides, etcGeological disastersI don't know。
And the “visibility” rises in water levels, which are more slow, hidden, “unseeable, unattractive” and often unprepared when it occurs。
This requires precision from a variety of dimensions, including early warning response, surveying, risk diversion and risk management。
“thanks to the staff members who came to us in the rain to persuade us to move in advance, otherwise the consequences would be dire.”
Reminiscent of the early morning of 23 may, li deyun, a villager in the blue sky village of the yangtze district of shangjiang, remains in a state of uncertainty。
Late that night, the slopes behind the house of the reedeyun family suddenly collapsed after sustained rainfall and the house was damaged. Fortunately, however, prior to the crisis, the staff had successfully persuaded his family and two neighbours to evacuate early through on-site research and patient counselling。
A successful escape saved eight lives。
Since this year, there have been 15 geological disasters in changsha that have caused no casualties。
Behind this is a set of data on the "demolition":
Longsha carried out a comprehensive screening of 724 geological disaster hazard hazard sites, 56,706 families at risk for building houses on cut slopes; issued 8 geohazard weather risk alerts, 18 risk alerts, and sent more than 354,000 alert messages; and conducted 6575 staff visits to hazard sites and families on cutting slopes, 35,742 visits and cumulatively 11,682 safe transfers。
For the time being, the persistence of heavy rainfall in the preceding period has resulted in an extremely saturated soil, and the risk of delayed disasters remains high。
To this end, changsha strictly enforces the “631” early warning call-back mechanism (6 hours in advance, 3 hours in advance, 1 hour in response). In particular, during heavy rainfall, village cadres and crowd surveyors are organized to come to the door and send a “last kilometre” of warning, so that they can turn early, turn around, leave no one behind or fall。
The ultimatum, the river pours
In the morning of 4 a. M., the sound of the alarm was sounded in susila, tea stand-in town in the peri-urban area。
Fortunately, this was not a real risk, but rather a site for an emergency drill in 2026, which was blocked in hunan province。
In the face of a simulated “crash” of about 8 metres wide, the recovery team quickly launched a method of “capping, cutting, retrieving”。
Pumping boats are parked on both sides, 6 metres of steel peddles go vertically into the water and bite closely into the synthetic steel wall; the motor bridge comes through and the water amphibious excavator throws a ton of bags..
In less than 20 minutes, the shroud locked the edge of the ulcer. With the last bag down, the current was completely cut。
"choose dragon success!"
In the past, flood resistance had depended on manpower, and in 1998 the images of soldiers holding their bodies against the flood had shed tears. Today, technology and hard work help。
The exercise's practical application of the “stretching technique” in a water-disturbing environment has provided a new approach to ripping open rivers. The technology allows for the rapid construction of barrage walls for steel pillars in a continuous water flow environment, effectively increasing containment efficiency and safety levels。
Intra-urban flooding is also the focus of prevention。
On 5 june, 81 excursors from the city of changsha city drainage centre participated in the training to restore the whole water pumping process。
They insisted on “first-january training”, and since the beginning of this year's season, they have been able to respond efficiently to multiple heavy rains with about 110 crash vehicles and over 300 personnel。
“i'd rather have to defend myself from the enemy than the enemy.”
Changsha will continue to focus on key areas such as the berm, the river lanes, low-lying areas, and the risk segment, conducting encrypted patrols, enhancing surveillance alerts, pre-empting risk forces, and protecting against risk rebounds and secondary disasters。
The examination is over today, but the examination for the main period will continue, and it must remain vigilant at all times and not allow for any laxity. The changsha departments at all levels will use defence as a “teststone” to test the performance of party members' cadres to ensure accountability, responsibility and responsibility and safety。
