Scope
GB/T 43246-2023 is the English-translated version of 全断面隧道掘进机制造监理技术要求.
GB/T 43246-2023 sets the technical requirements for supervising the manufacture of full face tunnel boring machines. A TBM is built once, for one tunnel, to a diameter and a geology that will not recur, and once it is launched it cannot be brought back: a defect in the main bearing, the cutterhead or the thrust system is discovered underground, where replacing it costs months. Independent supervision through design and manufacture is therefore normal practice on Chinese TBM contracts. The standard sets the general principles and then the supervision at each stage: the design stage, the manufacturing stage, and the site assembly, commissioning and acceptance stage. It took effect on 1 January 2024.

Technical requirements for manufacturing supervision of full-section tunnel boring machines
1 Scope
GB/T 43246-2023 sets the technical requirements for supervising the manufacture of full face tunnel boring machines. A TBM is built once, for one tunnel, to a diameter and a geology that will not recur, and once it is launched it cannot be brought back: a defect in the main bearing, the cutterhead or the thrust system is discovered underground, where replacing it costs months. Independent supervision through design and manufacture is therefore normal practice on Chinese TBM contracts. The standard sets the general principles and then the supervision at each stage: the design stage, the manufacturing stage, and the site assembly, commissioning and acceptance stage. It took effect on 1 January 2024.
This document stipulates the supervision technology for each process of the full-section tunnel boring machine in the design stage, manufacturing stage, and construction site assembly, commissioning, and acceptance stages. Require. This document applies to full-section tunnel boring machine manufacturing supervision services.
