The first domestic self-developed rescue shield machine participated in the first practical emergency rescue exercise – Passionategeekz

Passionategeekz On June 24, according to CCTV News, the “Emergency Mission・2025” Extreme Disaster Accident Scenario New Quality Rescue Capacity Test Exercise was held this morning. As one of the exercise topics, special exercises for emergency rescue operations such as circuit breakers, network breakers and power cuts were carried out in Dongting Village, Dongning City, Heilongjiang Province.

In the Dongting Village Railway Tunnel, China Railway organized China Railway Six Bureau and the National Tunnel Emergency Rescue Kunming Team carried out the Kunming Team of China Railway II Bureau.Rescue and rescue and escalation exercises of collapsed railway tunnels. During the exercise, the Kunming team of China Railway Second Bureau of the National Tunnel Emergency Rescue used the first domestic rescue shield machine independently developed in China to open up the rescue channel to rescue railway patrol personnel trapped in the tunnel due to landslides.

Passionategeekz learned from the report that although the rescue shield machine is also called “shield”, it is not the same as the shield machine used for engineering construction.Instead, it draws on the working principle of the engineering shield machine. “Its characteristic is that it is small and light. Compared with the mainstream large-diameter horizontal rescue drilling rigs, it is only 1/4 of its size and weighs only 1/7. It is very convenient for transportation and layout.” Li Yingping, political commissar of the Kunming Team of China Railway Second Bureau of National Tunnel Emergency Rescue, said that the diameter of this rescue shield machine is only 1.5 meters and can be widely used in the rescue of tunnels in different sections.

In addition, this rescue shield machine can also realize functions such as automated slag production, visual operation, real-time data return, and intelligent control.Only 5 people can complete the rescue operation. Li Yingping, political commissar of the Kunming Team of China Railway Second Bureau of National Tunnel Emergency Rescue, said that through practical exercise verification, the rescue response time can be shortened by 50%, and the risk of secondary collapse can be reduced by 80%, greatly improving the rescue efficiency and operational safety.
