Shi Hui of Junli Technology Delivers a Keynote Report
In the special technical seminar session, Shi Hui of Junli Technology delivered a keynote speech themed “Renovation of Active Flood Prevention Equipment in Underground Stations”. Combining the current situation of flood control safety in urban rail transit and the needs of operation management, she systematically elaborated on the pain points and difficulties in urban rail flood prevention, and provided an efficient and reliable active flood prevention solution for key areas such as entrances and exits, connecting passages and depots of rail transit underground stations.
Notably, all entrances and exits of the parking garage of Pushen Hotel, the venue of this conference, have been equipped with Junli’s hydrodynamic automatic flood prevention gates. During the conference, many participating leaders visited the site to have an intuitive understanding of the application effects of Junli’s hydrodynamic automatic flood prevention gates.

Hydrodynamic Automatic Flood Prevention Gate
As a star product of Junli Technology, the hydrodynamic automatic flood prevention gate is an innovative flood prevention device developed based on the principle of water buoyancy, which subverts the operation mode of traditional flood prevention facilities and has a number of core advantages:
No power required, automatic response: Realize automatic opening and closing relying on water buoyancy, without external power supply or manual operation. The opening and closing angle of the flood gate leaf is automatically adjusted according to the water level, ensuring stable operation even in extreme weather.
Scientific design, comprehensive functions: With a reasonable structure, it is convenient for installation and maintenance. It integrates multiple functions such as anti-collision warning, emergency vehicle passage, controllable circulation in non-flood periods and remote network supervision, meeting the application needs of complex scenarios in urban rail transit.
Reliable performance, remarkable results: The product has been included in the “Recommended List of Independent Equipment for China’s Urban Rail Transit”; it has passed the scientific and technological achievement evaluation of the Ministry of Housing and Urban-Rural Development, reaching the international advanced level; and it has passed the scientific and technological achievement appraisal of the State People’s Air Defense Office, reaching the domestic leading level. The product has been applied in metro projects in 17 cities across the country and promoted in nearly 1,000 underground projects in more than 30 cities nationwide. It has successfully blocked water for nearly 100 times with a 100% success rate, building a solid flood control safety defense line for rail transit and underground space.
