Abstract
Improvements in frontal advance machines by shield for the construction of tunnels, with an outer shield and an inner shield, in whose inner shield a cutting head is hooked with its alignment and actuation devices, and in which the inner shield together with the The cutting head can be advanced following the starting progression under support against the outer shield, characterized by the fact that the outer shield comprises two wrapping parts of shield equal in contour, which penetrate each other, and consists in total, at least over part of its periphery, of a number of support beams located next to each other movable both in axial direction and in radial direction with respect to the machine axis, which are joined on support devices and/or extensible devices forming groups and are like such mobiles together, a first group of support beams being coupled in the forward direction with the shield i nterior and a second group of support beams being staggered with respect to the first group.
