2.1 km tunnel saves electricity costs 4~50,000 yuan a month
Fan Qiushi introduced that the Gujiashan tunnel used a monthly electricity bill of 100,000 yuan. After nearly three months of operation statistics, it can save 4 to 50,000 yuan per month. "Because the tile reflection effect is good, it is usually open before. Half of the lamps can achieve the lighting effect.” Zheng Zhelun, the leader of the second brigade of the Sichuan High-speed Second Branch, said that after nearly three months of observation, the vehicles in the Gujiashan Tunnel were operating safely and orderly, and no traffic accidents occurred.
