Recently, *China National Defence News*, the authoritative national‑level official media on national defence, published a special report documenting the application of new civil air‑defence flood‑prevention equipment by Xuzhou National Defense Mobilization Office. It highlighted the application of Junli hydrodynamic automatic flood‑resistant gates. This marks the third time the product has been covered by *China National Defence News*, earning full recognition and authoritative affirmation from the national defence mobilization system. It delivers an innovative intelligent solution for underground spaces to resist rainwater backflow during flood seasons.
Heavy rainfall and water backflow in flood seasons pose major safety hazards to civil air‑defence projects, underground parking garages and other premises. Traditional sandbag water‑blocking solutions rely on manual labour, suffer delayed response and high on‑duty costs, and are prone to protection failure amid power outages or staff shortages. This third special report by the national‑level national‑defence media constitutes high‑level recognition from the national defence mobilization system for Junli Co., Ltd.’s technical strength and practical value of its flood‑resistant equipment. Faced with the new landscape of urban flood prevention featuring frequent extreme rainstorms, replacing labour‑intensive conventional flood‑fighting with technological innovation has become an irresistible trend for civil air‑defence development.
Previously, the hydrodynamic automatic flood‑resistant gate has been covered in official documents issued by multiple national defence mobilization offices including the National Civil Air‑Defence Office, Jiangsu, Suzhou, Wuxi, Chengdu and Xuzhou National Defense Mobilization Offices. Its outstanding water‑blocking performance has won high official recognition.
About Junli Co., Ltd.
Founded in 2013, Nanjing Junli Technology Co., Ltd. is a National High‑Tech Enterprise and Jiangsu Provincial Specialized, Refined, Differential and Innovative Small‑ and Medium‑sized Enterprise, focusing on R&D, production and services for smart flood mitigation of underground buildings. The enterprise has obtained honours including Nanjing Gazelle Enterprise, Nanjing Innovative Leading Enterprise and AAA‑Credit‑Rated Enterprise. It holds more than one hundred independent intellectual property rights. Its core achievements have been recognized and recommended by two national ministries and commissions and included in three national building standard atlases. The company leads the formulation of multiple national and association standards. Its products cover diverse scenarios such as civil air‑defence projects, rail transit, underground parking garages and substations. Having repeatedly won international and national‑level industry science and technology awards, it is a benchmark enterprise in China’s smart flood‑resistance sector for underground spaces.
The hydrodynamic automatic flood‑resistant gate achieves fully‑automatic opening and closing based on physical buoyancy principles. It requires no electric power drive or manual activation. Boasting well‑optimized structural design, convenient installation and easy maintenance, it integrates anti‑collision warning, emergency vehicle passage, controllable water flow under non‑flood conditions and remote network‑based monitoring. It meets requirements for fully‑automatic water‑blocking and backflow prevention at entrances of underground and low‑lying buildings. At present, the product has been deployed in thousands of projects across more than 40 provinces and municipalities nationwide, widely applied in civil air‑defence projects, entrances of underground buildings, parking garages, metro stations and other scenarios. It has successfully blocked floodwater for hundreds of projects with a 100% practical water‑blocking success rate.
