Abstract
Description
technical field
[0001] The invention relates to the field of tunnels and underground engineering, in particular to the field of TBM tunnel construction under complex geological conditions, more specifically, it is a hydraulic-mechanical TBM cutter head combined rock breaking method. The present invention also relates to the hydraulic-mechanical combined rock-breaking TBM cutter head adopted in the hydraulic-mechanical TBM cutter head combined rock-breaking method. The present invention also relates to a hydraulic-mechanical combined rock-breaking TBM device adopted in the hydraulic-mechanical TBM cutter head combined rock-breaking method. Background technique
[0002] The traditional TBM uses a mechanical hob to break rock, and the TBM hob often has three states when breaking rock, namely, small penetration, proper penetration and excessive penetration.
[0003] Under the condition of a certain hob spacing, if the penetration is too small, the cracks generated under the cut...
