Recently, at the 2026 Nanjing Comprehensive Flood Control & Emergency Rescue Drill, Junli’s flagship flood protection product — the hydrodynamic full-automatic flood gate made its appearance as innovative hardcore equipment and attracted widespread attention.
Rooted in Nanjing and serving flood control markets nationwide, Junli Technology will continue to upgrade its series of flood prevention products in the future to build a robust flood safety barrier for urban underground spaces during flood seasons.About Junli Technology
Founded in 2013 and established by a team of military officers transferred to civilian work, Nanjing Junli Technology Co., Ltd. devotes itself to the R&D, production and services of intelligent flood prevention solutions for underground spaces. It is a National High-tech Enterprise and a Jiangsu Provincial Specialized, Refined, Unique and Innovative SME.
The company holds more than one hundred independent intellectual property rights. It has participated in compiling three national building standard design atlases and led the formulation of multiple national, association and industrial standards. Its products have obtained certifications issued by two national ministries.
The Junli hydrodynamic full-automatic flood gate operates based on the water buoyancy principle. It requires no power supply or manual activation. The gate automatically flips upward to block floodwater once the water level reaches the trigger threshold and resets automatically as water recedes. When idle, it lies flat on the ground without obstructing vehicle and pedestrian traffic, featuring easy installation and routine maintenance. Up to now, the product has been deployed in nearly one thousand projects across more than 40 provinces and municipalities, including underground parking garages, metro stations, civil air defense projects and power substations. It has successfully prevented flooding for nearly one hundred underground projects with a 100% flood interception success rate.
