Scope
GB/T 34653-2017 is the English-translated version of 全断面隧道掘进机 单护盾岩石隧道掘进机.
China's national standard for single shield hard rock tunnel boring machines. It specifies the requirements for this type within the full face tunnel boring machine series.
The single shield machine is the answer to what the open machine cannot handle. It bores hard rock with the same disc cutters, but it runs inside a shield and builds a segmental concrete lining immediately behind the head, which means the tunnel is supported the moment it is excavated.
That matters where the rock is fractured, faulted or squeezing - conditions in which an open machine's grippers have nothing sound to push against and where the tunnel may close before support can be installed.
The trade is thrust: with no grippers, the machine pushes off the lining it has just built, so its advance is limited by what those segments can take, and it must stop to build a ring before it can advance again.
Choosing between open, single shield and double shield is the first decision on any hard rock tunnel, and it is made from the ground investigation.
