Chaijiali tunnel lighting project

Introduction: The tunnel area of Chaijiali tunnel has seasonal icing, frequent geological disasters such as landslides and debris flows, and the natural environment is relatively harsh, which is a difficult node in the project. The complex environment has put forward strict requirements for the lighting fixtures in the tunnel. As the supplier of the tunnel three-proof lamps, Longreen Lighting has provided a series of efficient and reliable outdoor three-proof lamps lighting solutions, including more than 14,000 sets of IP65 protection grade three-proof lamps .                                                                                                                                                                                                                                               With a total length of 244 kilometers, the Sichuan Jiumian Expressway starts from Qinglong Bridge in Jiuzhaigou County, Aba Prefecture, Sichuan Province, and ends at Zhangjiaping, Donglin Township, Youxian District, Mianyang City. It is expected to be completed and opened to traffic by the end of 2024. Chaijiali Tunnel, as an important node project of Sichuan Jiumian Expressway, has a total length of 3959 meters, of which the left width is 1987 meters, the right width is 1972 meters, and the maximum buried depth is 700 meters. The tunnel area is in Zhongshan terrain, and the tunnel structure is separate tunnel, which is a typical mountain road tunnel.
