a sediment storage tank; a slide tube having an open end and sliding back and forth linearly within the sediment storage tank;
An earth and sand pumping piston that reciprocates in the axial direction of the slide cylinder, a slide cylinder jack that reciprocates the slide cylinder, a piston jack that reciprocates the earth and sand pumping piston in the axial direction, and an earth and sand reservoir. A pressure-feeding pipe connected to the tank is provided, the slide tube is slid forward to take earth and sand into the slide tube, and the inside of the slide tube and the inside of the sediment storage tank are sealed and isolated, and the dirt-forced piston is slid forward. In an earth and sand pumping device that pushes out earth and sand in a slide cylinder and pumps it into a pressure pipe, the hydraulic switching valve of the slide cylinder jack, the hydraulic switching valve of the piston jack, and the hydraulic switching valve of the piston jack are connected to the slide cylinder through the respective hydraulic switching valves during the pumping process. The slide cylinder jack is equipped with a switching valve operating means for applying hydraulic pressure to the bottom side of the piston jack and the bottom side of the piston jack, and the slide cylinder jack is provided with a switching valve operating means that applies hydraulic pressure to the bottom side of the piston jack. An earth and sand pumping device characterized in that the earth and sand is generated as hydraulic pressure.
