MICROWAVE-ASSISTED TBM DOUBLE-HOB LINEAR-CUTTING ROCK BREAKING TEST DEVICE

摘要

Disclosed is a microwave-assisted TBM double-hob linear-cutting rock breaking test device. A microwave heating device is combined with a TBM hob rock breaking device for the first time, and microwave irradiation may be arranged at an intermediate position in a hob cutting trajectory and may also be arranged in the same trajectory as hob cutting. The device is used for studying the cutting performance of a TBM hob under the action of microwaves and a cutting rock breaking and abrasion mechanism of the TBM hob under the action of microwaves, so as to determine rational penetration and hob spacing under the action of microwaves, and further studying a new rock breaking technique combining a hard rock microwave cracking technique and a TBM apparatus.
