Abstract

The technique of digging with a pressurised shield. The method for supporting a working face of a piece of land involves injecting the mud downstream of the working face (T) in the direction of advance of the shield, so that it passes through the cutting tool (8), in order before and/or at the same time as the engagement of the tool to form a cake (C) for blocking and sealing the working face, which remains continually after the passage of the tooling for the purpose of ensuring a continuous blocking and seal of the working face stabilised by compressed air. The invention is used for the digging of a tunnel. <IMAGE>
