MINI-TBM 'SPECIFIC' FOR HARD ROCK

摘要

The present report contains some ideas to carry out the bore in the hard rock-mass, in order to have an underground passage for critic pipelines crossing, and a rock trenchless technology with a core-drill method. Chap. 1 deals with the art of current TBM and my option for new machines, more specific for hard rocks. Chap. 2 deals with petrografic morphology. Chap. 3 deals with the concept of the prototype. Chap. 4. deals with geotechnical and critical aspects Chap. 5. deals with datas on the supposed productivity. I am not an expert of large tunnelling, but a senior pioneer of pipelines networks. 1 wish to point out to younger people these applied research, which must put into concrete prototype for a new core-drill pilot method.
