As the pace of urban development and construction continues to accelerate, the country and various regions have introduced relevant policies to actively promote the construction of urban comprehensive pipe corridors. The document comprehensively analyzes the construction and application process of comprehensive pipe corridors in various regions based on the investigation of the current status and needs of pipe corridor signage in different regions in the country. There are problems such as lack of signs or inconsistent and non-standard settings. The establishment of standards for the identification of urban comprehensive pipe corridors is proposed to provide domestic pipe corridors with Provide a basis for the setting of the identification system, thereby standardizing the identification system of the pipe gallery, improving the operation and maintenance efficiency of the pipe gallery, and providing information for the safe operation of the pipe gallery. Necessary safeguards. Specifications for setting signs of urban comprehensive pipe corridors

1 Scope

GB/T 43239-2023 specifies the signage of urban utility tunnels. A utility tunnel is kilometres of confined space underground carrying water, power, gas and communications in separate compartments, entered by maintenance crews from several different utilities who each know their own cable and nothing about the tunnel. In an emergency the signs are the only thing telling them which way the nearest escape shaft is. The standard classifies the signs and sets the general requirements, then the requirements for setting them at each location - the compartments, the entrances, the hoisting openings, the escape routes, the intersections, the pipeline branch points, the control centre and elsewhere in the tunnel - followed by the production and installation, the acceptance and the maintenance management, with an informative annex giving the graphic style of the main public information signs. It took effect on 1 April 2024.

This document gives the identification classification of urban comprehensive pipe corridors, and stipulates the overall requirements, on-site setting requirements, production and installation, acceptance and maintenance manage. This document is applicable to the signage setting and management of urban comprehensive pipe gallery projects.
