PURPOSE:To improve the production efficiency by sucking and removing a highly water-absorptive resin gel deposited on the surface of a base material with a water-sealed vacuum pump. CONSTITUTION:A water feed valve 4 is closed, and a water-sealed vacuum pump 7 is operated to suck a highly water-absorptive resin gel 2 formed by absorbing the water deposited on the inner surface of a concrete product into a T-pipe 3. The valve 4 is opened, water is supplied from a water feed hose 6 to introduce the gel 2 staying in the T-pipe 3 into the pump 7 through a suction hose 5, and the water is discharged from a hose 8 connected to the pump 7. |
