Abstract
Improvements in equipment for drilling tunnels of the type that comprise a tubular protector, which may or may not incorporate mechanical ground-cutting tools, and which progresses progressively along a tunnel as the drilling is carried out, making the advance through of pistons or rams that act between anchor points or reaction in the protector and a tunnel lining that is introduced, section by section, behind or inside the back of the protector, as the drilling is carried out, characterized in that the rams are mounted on a car that is mobile, with the rams, along the guard, arranging means by which, at least in a position of the car, the push of the rams can be transmitted, to the anchor points or reaction in the protector.
