With the acceleration of industrialization, urbanization and modernization, various urban Urban tunnels and underground structures are increasing rapidly in cities across my country: Urban tunnels are a complex system that integrates multiple disciplines: The project has the characteristics of large project investment, complex technology, multiple operating facilities and wide coverage: There are a lot of people and a lot of vehicles passing through every day, and there may even be congestion during rush hour, which poses a hidden danger to the safety of urban tunnels: Once an accident occurs and causes traffic jam, the impact on urban traffic will be "thrombotic", which may cause heavy casualties and disasters: In particular, traffic congestion in large cities has seriously restricted our The rapid growth of China's urban economy: Whether urban tunnels are safe to operate is a matter of great concern to people's property and social stability: The operation and maintenance services of urban tunnels are of vital importance: This document helps operation and maintenance service providers build smart, safe, efficient and green The urban tunnel operation and maintenance service model solves the current problems of low systematization, single management method and lack of information sharing in urban tunnel operation and maintenance services: To ensure the safety and performance of urban tunnels, extend the service life of urban tunnels, and improve the quality and level of operation and maintenance services of urban tunnels: the goal of: Urban tunnel operation and maintenance service specifications

1 Scope

GB/T 43991-2024 is the Chinese service specification for operating and maintaining urban road tunnels. China has built urban tunnels at a rate that has left many cities with a maintenance liability they had no established practice for, and a tunnel is unforgiving: its ventilation, lighting, drainage, fire detection and suppression, traffic control and structural monitoring all have to work together, and a failure in any of them produces an incident in a confined space with no lateral escape. The standard sets the general requirements, efficient operation, safety and reliability, green and low carbon operation, continuous improvement and digital operation and maintenance, and then the service content itself: the daily operation and traffic management, the inspection regime for the structure and for each mechanical and electrical system, the maintenance and repair, the monitoring and the condition assessment, the emergency preparedness and response, and the records and the evaluation of the service. For a city authority or a contractor holding an operation and maintenance contract, this is the specification the service is measured against. It takes effect on 1 November 2024.

This document specifies the overall requirements, service content, service requirements, service guarantees, inspection and testing, evaluation and Improve: This document applies to operation and maintenance services provided by operation and maintenance service providers for newly built, rebuilt, and expanded urban tunnels: The operation and maintenance services of other tunnels can be used for reference:
