Abstract

CETTE TETE D'EJECTION POUR CONDUITE DE REMBLAYAGE PNEUMATIQUE COMPREND UN TRONCON DE TUBE 2 QUI FAIT PARTIE DE LA PARTIE AMONT DE LA CONDUITE ET QUI EST RACCORDE, D'UNE PART, AUX AUTRES TRONCONS DE CETTE PARTIE AMONT PAR DES RACCORDS SOUPLES ET, D'AUTRE PART, AU TRONCON SUIVANT DE LA PARTIE AVAL DE LA CONDUITE PAR UN RACCORD HYDRAULIQUE A LONGUE COURSE. CE TRONCON 2 EST MONTE DANS UNE MONTURE 3 DONT LE FLASQUE ARRIERE PRESENTE UNE GLISSIERE ET EST MUNI D'UN VERIN DE BRAQUAGE. POUR REMBLAYER DIRECTEMENT EN AVAL DU TRONCON 2, IL SUFFIT D'ACTIONNER LE RACCORD HYDRAULIQUE POUR PROVOQUER LA DECONNEXION ET DE BRAQUER LE TRONCON 2, SANS AUCUN DEMONTAGE. LA CONDUITE AMONT EST ALORS INCURVEE AVEC UN GRAND RAYON, DE SORTE QUE LE JET N'EST PRATIQUEMENT PAS AFFAIBLI ET QU'IL N'USE QUE MODEREMENT LES TRONCONS 1 ET 2.THIS EJECTION HEAD FOR PNEUMATIC BACKFILL DUCT INCLUDES A TRUNCON OF TUBE 2 WHICH IS PART OF THE UPSTREAM PART OF THE DUCT AND WHICH IS CONNECTED, on the one hand, TO THE OTHER TRUNKS OF THIS PART UPSTREAM BY FLEXIBLE CONNECTIONS AND, D '' ON THE OTHER HAND, AT THE FOLLOWING SECTION OF THE DOWNSTREAM PART OF THE PIPE BY A LONG STROKE HYDRAULIC FITTING. THIS TRUNCON 2 IS MOUNTED IN A FRAME 3 WHOSE REAR FLANGE SHOWS A SLIDE AND IS EQUIPPED WITH A TURNING CYLINDER. TO FILL DIRECTLY DOWNSTREAM OF TRUNCON 2, IT IS ENOUGH TO ACTIVATING THE HYDRAULIC CONNECTION TO CAUSE THE DISCONNECTION AND TO TURN TRUNCON 2, WITHOUT DISASSEMBLY. THE UPSTREAM LINE IS THEN CURVED WITH A LARGE RADIUS, SO THAT THE JET IS PRACTICALLY NOT WEAKENED AND IT ONLY USES TRUNKS 1 AND 2.
