Safety and Energy Saving Technology Practice of Highway Tunnel Operation——A Case Study of Shanghai-Chongqing and Chongqing-Guizhou Expressway Tunnel Group in Chongqing
In order to improve the operation safety and energy saving level of highway tunnels,this paper relies on the Shanghai-Chongqing and Chongqing-Guizhou expressway tunnel clusters in Chongqing to develop a new tunnel emergency safety active prevention and control system,which can be combined with the original expressway integrated control system to achieve fast,safe and flexible blocking of vehicles under emergencies,which also makes an iterative upgradation on the basis of the existing control platform,and effectively enhances the emergency control efficiency of highway tunnel.At the same time,the project team carried out a tracking test on the implementation effect of highway tunnel coating lighting improvement,lighting quality improvement and other technologies.The results show that the coating quality of the administered tunnel is good,the lighting index meets the requirements of the standards and specifications,the safety,energy saving and intelligent service level of the administered tunnel are improved.Corresponding maintenance and renovation plan was formulated to provide technical support for further reducing cost and increasing efficiency and strengthening risk control ability.
