Procédé de construction mécanisée de canaux hydrauliques

"MECHANIZED CONSTRUCTION PROCEDURE OF HYDRAULIC CHANNELS" particularly of semicircular section or circular segment, characterized in that, once the tracing of the two lateral sidewalks and the rough excavation by any means of the land included between said sidewalks, are rammed and on them are aligned planks with metal profiles (see formula) or rails that can be used as a guide for wheel sets that will serve as a mobile base for a trolley-bridge formed by a frame; On this frame, a strong tube coincides axially with the geometric axis of the half cylinder that will be the section that is executed; said shaft-tube receives its exact position by vertical graduation of the frame on its wheel axes and by transverse and vertical graduation of said bearings; the friction and profiling of the surface of the section of the channel is carried out integrally joining to said shaft-tube one or more radial poles having at their end rotating friction means; Immediately to said poles goes a similar group of poles, joined to the tube-shaft that at its end carry picking buckets, the shaft-tube has a toothed crown that meshes with a reducer of the speed of movement coming from an electric motor through of a clutch commanded at will, said mechanical set put in motion when turning with the tube-axis rubs with its appropriate means the walls of the channel and the detached products are picked up by the buckets that also in their turn drop the load On a transverse endless band located in the same frame; as the rotating rubbing means are leaving the surface of the channel with the intended diameter the cart is rolled on the tracks laid on the said side benches.
