Abstract

Process for manufacturing a tubular body constituted by a projected concrete wall, armed with continuous diffused framework, of any desired thickness, a process comprising the operations of: a) preparing a concrete mixture with water-concrete ratio such that it presents a characteristic essentially of zero slump; b) regulate the flow of said concrete mixture in order to obtain an essentially constant flow rate; c) project continuously and with constant flow the concrete, in the form of a laminar jet of thin thickness and essentially constant width, with high impact speed on the outer surface of a first layer constituted by a rigid tubular body, which rotates around of its own axis, d) running the point of impact of said jet against the surface of said tubular body, along the longitudinal axis of said tubular body and simultaneously with this operation of projecting the jet, applying on the surface of said body tubular, at a point preceding the point of impact of the jet, a helical shell of frame cable, in such a way that said jet produces a self-supporting layer of concrete that covers and engulfs said frame cable jacket and adheres to said tubular body. D) repeat in the opposite direction and continuity said operation of wrapping the cable and projecting the jet each time the latter reaches one of the ends of the tubular body, until the wall of the tube reaches the desired thickness, said wall remaining constituted by therefore, by a monolithic conglomerate of concrete that includes a series of concentric coaxial helical sheaths of continuous metallic cable.
