Scope

GB/T 35020-2018 is the English-translated version of 全断面隧道掘进机单护盾-土压平衡双模式掘进机.

GB/T 35020-2018 deals with dual mode full face tunnel boring machines that can work either as a single shield machine or in earth pressure balance mode.

It covers the terms and definitions, the basic parameters and model designation, the technical requirements and the test methods for these machines, followed by the inspection rules, the accompanying documents and the marking, packaging and transport.

Informative annexes describe the steps for converting between the two modes, a method for calculating the belt conveyor motor power and an inspection record table.

The standard applies to dual mode machines with a circular cross-section, and it relies on GB/T 34354-2017 and GB/T 34651-2017 for tunnel boring machine terminology.

Machine builders and tunnelling contractors use it for design, testing and acceptance. It was issued on 14 May 2018 and has applied since 1 December 2018.
