Abstract

The invention discloses a hydraulic cutting tool module. The hydraulic cutting tool module comprises a hydraulic cutting tool module frame, a thrust spring structure, a hydraulic cutting tool module thrust oil cylinder and a hydraulic cutting hob for combined rock breaking, wherein the thrust spring structure is located in the hydraulic cutting tool module frame, the hydraulic cutting tool modulethrust oil cylinder is located at the upper end of the thrust spring structure, and the hydraulic cutting hob for combined rock breaking is fixed to the lower end of the hydraulic cutting tool moduleframe and is of a spoke structure. The hydraulic cutting tool module has the advantages that the weight of the hob is reduced through lightweight treatment, and the rock breaking efficiency is improved. The invention further discloses a hydraulic-mechanical combined rock breaking TBM device. The invention further discloses a rock breaking method of the hydraulic-mechanical combined rock breaking TBM device.

Description

technical field [0001] The invention relates to the technical 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 cutting hob module of the hydraulic cutting hob. The present invention also relates to a combined rock-breaking TBM device, more specifically it is a hydraulic-mechanical combined rock-breaking TBM device. The present invention also relates to the rock-breaking method of the hydraulic-mechanical combined rock-breaking TBM device, more specifically, it is the rock-breaking method of the hydraulic-mechanical combined rock-breaking TBM device. 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. Under the condition of a certain hob spacing, if the penetration is too small, the crack...
