DREDGE PUMP Russian patent published in 2004 - IPC

FIELD: civil engineering. SUBSTANCE: invention relates to equipment for adjusting settlement and inclination of foundation. Proposed pump for impulse pressing-in of plasticized soil into spaces in foundation or tubular piles contains impulse jack with cantilever projections on housing and hopper for plasticized soil and plasticizer. Impulse jack is installed over nozzle widening downwards and provided with flange from below, cantilever projections from top and inlet holes from sides. Springs rest from top on cantilever projections of nozzle. Other ends of spring thrust against cantilever projections of impulse jack housing. Piston of impulse jack thrust from below against support beam in its center. Ends of support beam are connected by tie-rods passing through cantilever projections of impulse jack housing, through springs, and through cantilever projections of nozzle and are connected with nozzles. Side holes of nozzle are connected by pipelines with hopper for plasticized soil and hopper for plasticizer. EFFECT: provision of impulse pressing-in of sufficiently harsh soil mixture into nozzles to ensure forcing out and pulling out of foundation from soil mixture to preset value. 4 dwg
