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. Ce dispositif pour réaliser des diaphragmes à épaisseur constante au moyen d'une machine à mouvement alternatif afin d'obtenir des colonnes à base semi-circulaire de terrain consolidé par l'injection de mélanges à base de ciment, est caractérisé par le fait qu'à l'aide de deux cellules optiques (20; 21) placées à un angle variable, reliées à un système électrique qui commande des électro-vannes oléodynamiques (30; 31), on obtient un mouvement alternatif formant un demi-cercle de terrain retourné à la profondeur voulue et devant être consolidé par des mortiers à base de ciment.
