Recently, many regions have promoted the renovation and upgrading of underground protective projects. A number of underground fortresses with both protective functions and people's livelihood value have been put into use one after another, which not only strengthen the safety line but also expand the application scenarios of urban underground space.
Focusing on the core of "integration of peacetime and wartime use", this renovation involves structural reinforcement and functional optimization of existing underground protective facilities. It adopts thick-walled reinforced concrete pouring technology to improve impact resistance, and is equipped with poison filtration and ventilation, emergency power supply and other systems to ensure the safety and basic living needs of personnel under special circumstances. At the same time, it integrates popular science and education, convenient services and other functions, and sets up civil air defense knowledge exhibition areas and emergency skills training areas, allowing the public to learn protective knowledge and master self-rescue skills in daily life.
The renovated underground fortresses can be used as underground parking and material storage spaces in peacetime to alleviate the pressure on urban ground; in special periods, they can be quickly converted into protective shelters to provide safety guarantee for the public. Relevant person in charge said that in the future, we will continue to promote the quality improvement and upgrading of underground protective facilities, promote the efficient utilization of underground space resources, and realize the organic integration of safety protection and people's livelihood services.
