In 18 years, Mianyang Ren Han Yuping developed a tunnel reflective tile and won the “Red Dot Award”, which is known as the global industrial design Oscar, and was first applied in the Gujiashan Tunnel of the Qinling Tunnel Group of Beijing-Kunming Expressway (Chengdu Business Daily reported). On the 19th, the relevant person in charge of the Guangyuan Management Office of Sichuan Expressway Chuanbei Company introduced that after nearly three months of operation, the use of reflective tiles in the tunnel not only made the tunnel no longer dark, but also reduced the driver's panic, and there was no accident. At the same time, due to the good reflective effect, the 2.1-kilometer single hole can save electricity costs of 4 to 50,000 yuan per month.
On the afternoon of the 19th, Chengdu Business Daily reporter came to the ancient Jiashan tunnel of the Beijing-Kunming high-speed Qinling tunnel group. The tunnel has a total length of 2,102 meters, a total of 1.3 kilometers with reflective tiles on both ends, and a total of 20,000 square meters are used. The tile color is Ivory white.
