Scope

Main technical content: This specification is compiled in response to the requirements of the Ministry of Transport's General Office's "Action Plan for Promoting the Quality and Upgrading of Highway Tunnels" (Jiao Gong Lu [2019] No. 9) and the "Technical Specification for the Quality and Upgrading of Highway Tunnels" (Jiao Gong Lu [2019] No. 28). With the rapid increase in the mileage of highway tunnels in China and the growing demand for the management and maintenance of tunnel electromechanical facilities, this specification is of great significance for guiding the technical condition inspection and evaluation of electromechanical facilities in highway tunnels in service and optimizing maintenance work. This specification is divided into nine chapters, including: 1 General Provisions, 2 Terminology, 3 Basic Provisions, 4 Monitoring Facilities, 5 Communication Facilities, 6 Power Supply and Distribution Facilities, 7 Lighting Facilities, 8 Ventilation Facilities, and 9 Fire Protection Facilities. The specification provides a detailed explanation of the inspection content of electromechanical facilities in highway tunnels in service and the calculation method of equipment integrity rate, and sets clear rules for the evaluation of the technical condition of tunnel electromechanical facilities.
