Abstract

PURPOSE: To dredge sand and mud in a pit or the like at a high efficiency by providing a sand pump with a mud suction tube and a mud feed tube and a sink and float device to a body with a warped bottom section in a backet type sand/mud dredging apparatus.
CONSTITUTION: When an air suction/discharge valve 25 is opened, air is fed into a float 16 while water inside is discharged from a water suction/discharge port 16A. The float 16 comes up to float the body maintaining it at a specified position. When the air suction/discharge valve 25 is closed to halt the air supply, the air in the float 16 is discharged to reduce the pressure. As water enters the float 16, the body 11 submerges down, collects accumulated earth 9 and sucks it into a mud suction tube 13.
