Embodiment Construction

[0081] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.

[0082] Referring to the accompanying drawings, it can be seen that the hydraulic-mechanical TBM cutter head combined rock breaking method includes the following steps,

[0083] Step 1: Install the combined rock-breaking TBM cutter head 4, and align the combined rock-breaking TBM cutter head 4 with the position of the cavern to be excavated (ie, the tunnel surface 18); the mechanical hob structure equipped on the TBM cutter head has enough Strong strength and rigidity, able to withstand the huge reaction force and shear stress generated by the cutterhead rotation and advancement during the excavation of the main engine;

[0084] Step 2: Fix...

Abstract

The invention discloses a hydraulic power-mechanical TBM cutter head combined rock breaking method. The hydraulic power-mechanical TBM cutter head combined rock breaking method comprises the steps that a combined rock breaking TBM cutter head is installed, and the combined rock breaking TBM cutter head is aligned to the position of a to-be-excavated grotto; a TBM outer machine frame is fixed, anda combined rock breaking TBM is started and is enabled to tunnel forwards for a stroke; and the referred steps are repeated, the next stroke operation is started until tunneling is carried out to a specified distance, and excavation of the grotto is completed. The hydraulic power-mechanical TBM cutter head combined rock breaking method has the advantages of suitable penetration degree and high rock breaking efficiency. The invention further discloses the hydraulic power-mechanical combined rock breaking TBM cutter head adopted by the hydraulic power-mechanical TBM cutter head combined rock breaking method. The invention further discloses a hydraulic power-mechanical combined rock breaking TBM device adopted by the hydraulic power-mechanical TBM cutter head combined rock breaking method.

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...
