Abstract (en)
[origin: WO0183949A2] A device for producing an underground tunnel comprises an excavating device which can be moved through the ground, in order to form an elongated hole in the ground. Formwork placed in the hole behind the excavating device bounds a formwork space between the formwork and the wall of the hole, and supports a lining material in the formwork space. Provision is also made for lining material supply means, for supplying the lining material to the formwork space. A controllable valve forms part of the lining material supply means, and comprises a valve housing with three housing apertures, a rotatable valve body being capable of forming a connection between two of the three valve bodies for supplying lining material, on the one hand, and cleaning supply pipes, on the other hand. A lining material pump is filled under pressure with lining material.
