Summary: | The device for producing diaphragms of constant thickness by means of a machine with reciprocating movement in order to obtain columns of earth on a semicircular base, the earth being consolidated by the injection of cement-based mixtures, is characterised by the fact that with the aid of two optical cells (20 21) placed at a variable angle and connected to an electric system which controls oleodynamic solenoid valves (30 31), a reciprocating movement is obtained forming a semicircle of earth turned over to the desired depth and which is to be consolidated by cement-based mortars. |
