Method And Device For Continuously Informing The Operator Of A Tunneling Machine On Physical Features Of A Ground To Be Tunnelled

摘要

The invention relates to a method for informing the operator of a tunnelling machine on physical features of a ground to be tunnelled consisting in placing one or several sensors ( 1 - 4 ) directly on each cutter wheel of a drill head, wherein said sensors are selected such that they are capable of transmitting representative signals of the cutter wheel penetrating force into the ground, a rotating state, the position and the temperature of the cutter wheel and in transmitting said information to the operator of the tunnelling machine. Said invention is particularly suitable for detecting hard rocks during digging an excavation by means of a tunnelling machine.
