On June 28th, this site reported on part of the armed police officers and soldiers of the rescue and disaster relief site in Maoxian County, Sichuan (according to the emergency rescue equipment for the Armed Forces of Landslides in Diexi Town, Aba Prefecture, Sichuan Province). Today, we continue this topic to look at China's scientific and technological disaster relief. the power of! At the rescue site of the mountain collapse disaster in Maoxian County in Sichuan Province , professional equipment such as life detectors , slope radars, and drone-borne laser radars are widely used. Armed police rescue teams, mine search and rescue teams, and private professional search and rescue teams are responsible for scientific search and rescue. Under the unified command of forces, the forces are coordinated and efficiently rescued. The disaster relief forces in China continue to enhance scientific and professional response capabilities in the event of disasters. On June 26, the slope radar capable of monitoring landslides monitored the deformation of the landslide at the site of the collapse of Maoxian Mountain in Sichuan Province. Professional equipment science search and rescue At the search and rescue scene, the reporter saw that both the armed police rescue team and the private professional search and rescue team carried mostly life detectors and rescue dogs. The search and rescue teams of the People's Armed Police Force and Hydroelectric Force used carbon dioxide detectors and snake-eye detectors equipped with cameras to conduct search and rescue. Once signals were found to be abnormal, they could further explore the existence of signs of life underground. On the morning of June 26 , the Earthquake Rescue Team of the Armed Forces Golden Army is in search and rescue area No. 2 and observes and collects disaster relief information through drones. “ At 14 o'clock on the 24th , we arrived at the disaster area and made the basic data map with drones for the first time. Today, we further draw a comprehensive orthophoto map to make a detailed analysis of the disaster area environment.†The unit unmanned crew Captain Yan Buqing said that the use of drones has changed the search and rescue history of previous disaster exploration sites, and improved the search and rescue efficiency while protecting the safety of rescue workers. On June 26, rescue workers used a life detector to conduct search and rescue at the collapsed mountain site in Mao County, Sichuan Province. The geological monitoring equipment such as slope radars and airborne laser radars are also put into use. According to the technicians, the UAV airborne laser radar invested by the State Administration of Work Safety on the spot is different from an ordinary drone that can only shoot images. This professional device can quickly acquire the topography and topography and the depth of the accumulation layer in the air to calculate The amount of landslides, analysis of the causes of the disaster, and assistance in identifying key search and rescue areas. On June 26th , Yang Xiaolin, a senior engineer at the Chinese Academy of Sciences, used a slope radar to monitor the surface displacement of the cavern body in real time. Even if a giant mountain surface only has millimeter-level deformation per hour, it can be accurately monitored and comprehensively judged. Risk, guarantee the safety of rescue. On June 25, the Armed Police Rescue Team and the rescue dogs were searched and rescued at the collapsed mountain site in Mao County, Sichuan Province. An on-site rescue worker from Luqiao, Sichuan, said that professional equipment has helped the rescue. In the past, rescuers needed to venture into the disaster-hit areas to conduct situational visits, and they were able to grasp the situation on the spot at the first time through professional equipment, which was conducive to scientifically formulating rescue plans. The search and rescue team of the Earthquake Rescue Team of the Armed Forces Golden Army believes that the use of scientific instruments and professional equipment has greatly improved the search and rescue efficiency. Professional team efficient rescue After the disaster, all parties quickly assembled to the disaster area. Sichuan Armed Police Fire, Deyang Earthquake Rescue Team and Chengdu Feibao Rescue Team were quickly assembled and dispatched; the army used helicopters to send medical teams to the scene... On June 26, the Armed Police Rescue Team conducted a search and rescue at the collapsed mountain site in Mao County, Sichuan Province To at 18:24 on June Ri Xu, police officers, traffic construction, mine rescue more than 1,000 rescue forces and equipment 153 vehicles, we have arrived at the scene one after another all-out rescue work. 2.5km disasters damaged power lines, State Grid Power Company in Sichuan first batch of 50 rescue teams, carrying 10 engineering vehicles, a 400 kilowatts of large power cars, three generators, 20 sets of emergency lighting devices, in 6 At 1200 hours on the 24th arrived at the scene. Sichuan Mobile put more than 70 emergency rescue personnel on site , 3 emergency communication vehicles, 9 satellite phones and 260 kilometers of optical cables . Sichuan Road and Bridge, Sichuan Trading and other units were in the collapsed area on the 25th to reclaim a rescue road that was more than 2 kilometers long , and they continued to widen to 8 to 10 meters. Mechanical equipment, personnel, and materials enabled fast and safe access. On June 26, rescue workers used a life detector to conduct search and rescue at the collapsed mountain site in Mao County, Sichuan Province. “When we rescued people in the mountains earlier, because of poor communication, there have been repeated search and rescue operations. Communication, electricity, materials, and road access guarantees have greatly improved the effectiveness of on-site search and rescue,†said Yan Yudong, head of the Yongan rescue team of the private rescue agency. According to the rescue and disaster relief frontline headquarters, the first task at the first time is to save people. In view of the limited road capacity and the narrow search and rescue operation surface, the command headquarters organizes all parties’ forces to carry out search and rescue and prevention in a scientific and orderly manner. Health disasters. “The rescue was more scientific and orderly. We quickly learned about the key search and rescue areas and took the lead in search and rescue in these areas.†Li Junyu, the search and rescue team member of the Armed Police Hydroelectric Force, said that the traffic control along the way was also very effective and avoided the massive disorder of rescue teams and vehicles. Influx, blocking the rescue road. “This time we conducted an effective division of labor, and in accordance with the requirements of the headquarters, we participated in disaster relief in batches, and evacuated in batches. While contributing to our efforts, we also increased the efficiency of our rescue efforts.†said Wei Weidong, director of the Chengdu Youth Emergency Search and Rescue Team. In disaster relief, there is often a lack of coordination. Scientific prevention brings hope At present, large-scale rescues have not yet recovered from the accumulation of landslides. Geological experts involved in search and rescue revealed that the probability of survival is very low for people with high mountain collapse and burial. To avoid secondary collapse caused by the collapse of the cavern body, it is not possible to dig deep in search and rescue. Aerial photographs of Sichuan Maoxian Mountain collapsed on June 26 Reporters at the rescue scene, three times to see the life detecting device abnormal signal June 25. 9 o'clock in the river 3.9 meters below the ground signal abnormalities, but no response to rescue dogs, fire officers and soldiers repeatedly stripped earth and stone, with two search dogs and life detector repeatedly screened, and ultimately confirmed no signs of life; Armed Police Sichuan Corps rescue team found abnormal the signal, excavation to 5 meters deep, the final abnormal signal has disappeared; No. 4 SAR region, Sichuan fire found abnormal signal, the signal at the next point with a shovel open three meters deep underground work plane, and a shovel Such tools as stripping earth and rock from the side, so as not to cause the possible collapse of living space until the discovery of wood beams and plastic windows, but in the end there is no miracle of life. A rescue worker said that the abnormal signal does not completely equal to the signs of life. In addition, the thickest part of the cavernous stacking layer reached twenty to thirty meters. The location of the anomaly signal was found to be several meters below the ground, and oxygen deficiency was not ruled out. The survivors’ vital signs continued to weaken until they were killed. There are more than 900 geological hazards in Maoxian. The county seat of Maoxian County is located on the ancient landslide. There was a 7.5 -magnitude earthquake in Diezhan Town in 1933. The center of the Diexi River almost collapsed after the earthquake. A cadre in Maoxian County said that Maoxian County is located on the plateau and there are abundant products in the valley area. Many people live here, but the terrain of Jiayigou in the two mountains often forms geological disasters. According to statistics, there are millions of geological disasters and hidden points in the country, among which over 34,000 are geological disasters, and the proportion of landslides in geological disasters exceeds 70% . “Large landslides are difficult to prevent and cause great harm,†said Xu Qiang, deputy director of the State Key Laboratory of Geohazard Prevention and Geo-environmental Protection at Chengdu University of Technology. “The good news is that the National 973 Plan project identified and prompted precursors to large-scale hidden landslide hazards. Research on Information Acquisition and Early Warning Methods. After more than 10 years of research by the joint research teams of eight universities and research institutes , it has achieved initial results. Xu Qiang said that the research results have been applied in the landslide warning practice in Danba County, Sichuan Province and Heifangtai, Yongjing County, Gansu Province. May 13 this year, Black Taipei side chenjiagou happened with 2000 cubic meters of loess landslides, one week in advance to achieve issued a yellow alert for landslides, 39 minutes before the system automatically sends a red alert, evacuate the nearby farming and grazing workers, No casualties were caused.
