In the achievement display session, as an invited representative of outstanding external scientific and technological achievement transformation cases, Shi Hui took the stage first to deliver a keynote speech themed “Research and Development of Underground Space Flood Prevention Technology”. He systematically shared Junli Technology’s innovative achievements and practical experience in the flood prevention field, highlighting the technical advantages of the company’s core innovative achievements by comparing the drawbacks of traditional flood prevention methods, realizing a leapfrog upgrade from “passive water blocking” to “intelligent early warning and active protection”. Emphasizing that the value of science and technology lies in empowering practical applications, Shi Hui also shared core experience in achievement transformation. Through multi-scenario implementation verification nationwide, the scientific and technological achievements have been truly transformed into a solid hard power for safeguarding urban safety.
Being invited to share as an outstanding achievement transformation representative is a recognition of Junli Technology’s technical strength in flood prevention. In the future, Junli Technology will continue to deepen technological R&D, promote the implementation of more innovative achievements, and contribute to enhancing the resilience of urban underground spaces!

01 Full-automatic and Electricity-free
Driven by pure physical water buoyancy without the need for electricity, it can respond quickly in emergency situations, ensuring efficient flood prevention.
02 No Manual Operation Required
It automatically blocks water when encountering backflow without manual activation. For maintenance or pre-setting, it can also be quickly opened manually, offering flexibility and convenience.
03 Invisible Installation, Space-saving
Adopting embedded installation (flush with the ground) or surface-mounted installation (serving as a speed bump), it neither damages the original architectural appearance nor affects the normal passage of people and vehicles. It is widely applicable to various scenarios such as underground garages, subway stations, underground shopping malls, and civil air defense projects.
04 Proven in Practice with Outstanding Reputation
Nearly 1,000 sets have been installed in projects such as underground garages, subways, and power substations worldwide. It has successfully blocked floods for underground buildings nearly 100 times, constructing a solid and reliable flood prevention barrier. The company maintains high customer repurchase and recommendation rates.
