At about 4: 26 pm on the 1st, a female trapped person was rescued by fire rescuers from the scene of the collapse accident of Changsha residents’ self-built houses, and applause rang out at the scene.
"Can you see that glow stick?" "I can see it." "Don’t be afraid, don’t be afraid, many people are helping and saving you!" This is a conversation between the trapped person and the fire rescuers at the scene of the accident rescue.
At 12: 24 on April 29, 2022, a self-built house collapsed in Jinshanqiao Street, Wangcheng District, Changsha City, Hunan Province. It was initially verified that there were 23 people trapped in the house. At present, 6 people have been rescued, and 39 people lost contact near the incident. After the incident, a rescue started quickly. In the early morning of May 1, Xinhua News Agency reporters followed the Changsha Fire Rescue Detachment into the building on the west side of the collapsed self-built house and directly attacked the scene for rescue.

"You must keep your strength, we are saving you!" Firefighters and rescuers encouraged the trapped people. Every once in a while, they will communicate with the trapped people to calm their emotions. As of press time, fire and rescue workers are still nervously rescuing at other points at the scene of the accident.
Zheng Zhang, deputy detachment leader of Changsha Fire Rescue Detachment, said that the partially collapsed buildings on the east and west sides have brought great difficulties to the rescue. First, it is necessary to ensure that the trapped people will not suffer secondary injuries. The reporter saw at the scene that the staff carried out rescue from the front and back of the collapsed house at the same time, and a number of large-scale equipment and personnel from relevant units such as China Construction Fifth Bureau were on standby at the scene.
Chen Yong, secretary of the Party Committee and Chairman of the Third Company of China Construction Fifth Bureau, said that the rescue currently faces several major difficulties in terms of the collapse site structure. First, the collapsed buildings are complex in structure, and various components are intertwined, and the stress state is unknown; Second, the houses on both sides were hit by collapsed houses, and the main load-bearing members were seriously damaged; Third, the operation surface is narrow and the terrain is complex, which makes the operation difficult; Fourth, if a large area is demolished, the collapsed part will be disturbed greatly, which is easy to destroy and cause greater damage.
On the afternoon of April 30th, firefighters and rescuers found signs of life in the building through manual search and rescue combined with rescue dogs, radar life detectors, audio life detectors and snake eye detectors.

Rescuers found that the trapped people were "buried deeply at that time", and the working face was narrow and the terrain was complex, so they could not use large equipment and could only use small equipment to advance.
It is necessary to use scientific rescue methods to ensure safety, but also to seize the "golden 72 hours" time; It is necessary to reduce the time for trapped people to be buried, and do our best to reduce the possibility of secondary injury to trapped people.
Rescuers kept in touch with the trapped people by shouting and other means, and also provided physiological saline supply and psychological counseling to the trapped people, while at the same time grasping the demolition.
The reporter observed that during the demolition process, rescuers encountered obstacles such as refrigerators. If it is cut rashly, it may cause great vibration, causing the wall rubble to fall off again, or the structure is unstable. Therefore, rescuers call small metal cutting equipment to expand the rescue surface. "We use light and simple electric demolition tools because they have little vibration." Zheng Zhang said.
The rescue is moving forward in a scientific and steady way. "This is the first time I have faced such a difficult rescue in my nearly 30 years as a firefighter." Zheng Zhang said, "We will do our best, and we have obtained the strongest strength and the most cutting-edge equipment."
Rescue, from day to night and from night to dawn, many people stick to the scene and stand by at any time.
The reporter learned that at present, more than 700 firefighters, armed police officers and soldiers and social emergency forces have been dispatched urgently, and more than 120 sets of rescue equipment and rescue dogs such as fire engines, large cranes, power generators and life detectors have been mobilized.

Chen Yong told reporters that after getting the news of the accident at noon on April 29, the third company of China Construction Fifth Bureau convened more than 100 staff members to rush to the scene within one hour. "Many people saw the call in the group and immediately responded spontaneously." At present, they have set up a temporary party branch in party member with more than 50 members.
As of the early morning of May 1st, the Third Company of China Construction Fifth Bureau mobilized 19 muck transporters, 7 excavators of different models, 6 climbing trucks, 3 cranes, 59 sets of cutting machines and other rescue equipment to the site. "Race against time, but only if it is scientific and safe." Words don’t say that finish, Chen Yong and led to the core area to further explore the scheme.
The National Emergency Medical Rescue Team of the Second Xiangya Hospital of Central South University was always on the scene. "We have carefully made a rescue work plan, repeatedly adjusted and refined it, specifically how to arrange each ambulance for everyone."
"We adhere to the concept of life first and people first. As long as there is a glimmer of hope, we will make a hundredfold effort!" Zheng Zhang said.
On the morning of May 1st, measures were taken to fix the dangerous houses on both sides of the collapsed houses to ensure the safety of the rescue process. The reporter saw at the scene that the construction workers had used special equipment to cut the top stainless steel structure of the collapsed house. Chen Yong introduced that after cutting and hoisting, it can create favorable conditions for firefighters to search and rescue and help speed up the rescue progress.
