Abstract

In a device for the pneumatic discharge of hydraulic construction material conveyed hydromechanically for underground workings, in which the wet construction material pumped in the form of a dense stream has added to it compressed air in front of an opening, especially in the form of a nozzle, which serves for effecting discharge, and this compressed air is injected outwards together with the construction material, provision is made, in accordance with the invention, for the dense stream of pumped construction material to have compressed air, supplied as a stream, added to it, closing with respect to the external air by means of the wet construction material, and it is thereby distributed in the compressed-air stream and transported together with the compressed air to the opening and extracted therefrom.
