At the end of 2024, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council issued the “Opinions on Promoting the Construction of New Urban Infrastructure and Building Resilient Cities”. The opinions state that “it is necessary to promote the improvement of the drainage and flood control capabilities of key facilities such as underground facilities, urban rail transit and their connecting passages, and at the same time strengthen the functions of flood prevention, theft prevention and power outage prevention in underground garages and other places.” These key contents undoubtedly focus precisely on the core guiding points of flood prevention and inundation prevention, providing a clear direction for the research, development and application of relevant industries and various innovative products.
## Great News
Since its launch, the hydrodynamic automatic flood prevention gate independently developed by Junli Co., Ltd. has been highly favored by the market and has repeatedly received the Construction Industry Science and Technology Achievements Promotion Project Certificate evaluated by the Science and Technology and Industrialization Development Center of the Ministry of Housing and Urban-Rural Development. Winning this honor again fully reflects the reliability of Junli’s hydrodynamic automatic flood prevention gate, which can continuously and effectively block water and prevent backflow at the entrances and exits of underground spaces such as subways and underground garages.
It is particularly worth mentioning that Junli’s hydrodynamic automatic flood prevention gate does not require electricity and uses the buoyancy of water to complete automatic lifting. This feature completely eliminates the hidden danger of affecting its use due to power outages at the source. This also fully and powerfully demonstrates that Junli has fully considered the fit between the product and the actual market demand during the research and development period. Starting from the actual application scenarios, it has truly developed an effective product, which is also in line with the policy orientation and the trend of the market.

## Some Media Reports
◎ Since the installation of the hydrodynamic automatic flood prevention gate developed by Nanjing Junli Technology Co., Ltd. in the civil air defense project of Sanyuan Yicun Community in Gusu District, Suzhou in 2021, it has automatically floated up to block water many times during heavy rainstorms, successfully preventing rainwater from flowing back, ensuring the safety of the civil air defense project, and winning praise from the residents.
◎ During the heavy rainstorm on June 21, 2024, at the underground garage of Jinkui Park in Wuxi, Junli’s hydrodynamic automatic flood prevention gate started quickly and blocked the flood like a solid high wall.
◎ During the heavy rainfall on July 13, 2024, Junli’s hydrodynamic automatic flood prevention gates in the civil air defense garages of Nanchan Temple and the Ancient Canal in Liangxi District, Wuxi also played an important role in blocking the accumulated water on the streets.

In addition, after Junli’s hydrodynamic automatic flood prevention gates were installed in subway stations in Beijing, Hong Kong, Nanjing, Guangzhou, Suzhou, Shenzhen, Dalian, Zhengzhou, Chongqing, Nanchang, Shenyang, Shijiazhuang, Qingdao, Wuxi, Taiyuan and other places, they have successfully withstood the impact of simulated floods during multiple water test acceptance checks, demonstrating good flood prevention effects and stability, and effectively ensuring the safe operation of subway stations.
## Both Practical and Forward-looking
As the times move forward, the climate challenges faced by cities are becoming more complex, changeable and severe, and the requirements for urban resilience are constantly increasing. The safety guarantee of underground spaces has become a key link that must be fully committed to and focused on in the process of urban construction. Under such a general trend, the market’s demand for high-quality products that can effectively solve the problems of water blocking and backflow prevention in underground space
