The project in brief
When the G85 Yu Kun Expressway going through Chongqing in the Kunming Province required two tunnels through a massive mountain rock (Qiujiayakou Tunnel and Dakouzi Tunnel), the TUNPROTEC® system was the go-to solution.
The TUNPROTEC® system allowed for fast installation within the tunnel and the small dimensions of the system components ensured an unobtrusive means of protecting the tunnel from fires.
The G85 Yu Kun Expressway is part of the 5th longitudinal high standard road of the China expressway network. Yu Kun Expressway strethes 543 km in the Kunming and Yunnan Province.
