摘要： A plant for use in tunnel constructions and having a drive shield with a cutting head for driving into a working face to advance the tunnel. A plurality of rams which act upon an abutment member are used to drive the shield forwards. The abutment member transmits the forces from the rams to a mass of fluid concrete introduced under pressure and supported on support means such as a tubular shell or series of rings spaced inwardly from the tunnel wall. The concrete when hardened forms a continuous lining for the tunnel wall. Water is removed from the fluid concrete with the aid of filters provided on the abutment member of the support means.
