Title: Apparatus for producing a wall

Abstract: A form for producing a wall, particularly for an underground gallery, comprises a plurality of support members spaced from each other and casing elements supported on the support members. Each casing element includes two casing plates spaced from each other and consisting of shape-retaining synthetic resin, end and side walls extending between the casing plates, and a set of substantially parallel webs of synthetic resin. The webs connect the casing plates to provide a shape-retaining support for the casing plates and to transmit between the plates stress and pressure forces to which the casing element is subjected.
