The opening mode of protective equipment for utility tunnels differs from conventional civil air defense equipment, and ordinary civil air defense products cannot be directly applied here. To adapt to new application requirements, our company has participated in the development and production of dedicated protective equipment for utility tunnels, jointly designed by China Urban Construction Design & Research Institute Co., Ltd. and Qingdao Civil Air Defense Office. The products cover protective facilities for escape openings, material feeding ports, ventilation openings and personnel entrances of utility tunnels.
