To open and transfer a fine layer of material, adherente on a wall, the structure of a wall for the implementation of the process and device for transporting concrete comprising the structure of the wall.

摘要

The present invention relates to a process in order to open and transfer a fine layer of material adherente on a wall, a filter or a membrane. / p & & p & the process of the invention consists in succession: / p & & p & - to be formed on the front wall 4 thereof of the material, of the deformations multiple by suction of an elastic membrane 5, on a grid 8 fixed to the wall 4, by means of a vacuum source 10 and / p & & p & - to be omitted, when the layer adherente is brittle, the deformations above by recovery of the pressure in the chamber 7 by means of a free air 11; / p & & p & - to be produced from shocks localized on said surface 5 in order to break up the layer adherente. / p & & p & the present invention applies in particular in the industry of the structure.
