T/CCTAS 161-2024 High-pressure water-rich tunnel construction technical regulations
Basic Information
Scope
Main technical content: This specification stipulates the basic requirements, construction requirements, advance geological forecasting, grouting, water drainage, excavation, monitoring and measurement, safety and emergency management for high-pressure water-rich tunnel projects. It is applicable to high-pressure water-rich tunnel projects of railways, highways, urban rail transit, and urban roads constructed by drilling and blasting methods. It fully absorbs and draws lessons from existing scientific research results and engineering practice experiences at home and abroad, enabling technicians to effectively guide the construction of high-pressure water-rich tunnel projects in accordance with this specification, construct according to the design documents, meet the requirements of the structural safety, durability performance, and system use function of the project, and ensure normal operation within the designed service life
