    • PURPOSE: To provide an apparatus that can be buried under the bottom of water by adopting such a configuration that a chamber has inlets for pressurized water and communicats with a plurality of apertures of a structural frame for discharging a pressurized water jet, and fluid operated pumps operate by the pressurized water to suck water-suspended solids to a discharging-flow means. CONSTITUTION: When inlet ports 20, 21 are connected to pumps and pressurized seawater is supplied to the inlet ports 20, 21, the pressurized water flows into an outside chamber portion 6b, and falls into a lower box member chamber 12 through a pipe 10, and divides into a jet pump inlet port 26 and a nozzle 36, and jets from the nozzle 36. In a jet pump 25, because the pressurized water passes through the inlet port 26 and enters portions 27a, 27b, a sucking action is generated. Water-suspended solids such as soil, sand, pebbles are sucked through a suction port of the jet pump or are caught in a water flow caused by the suction of the jet pump, and are discharged far away from a cofferdam 1 through a tubular member 29 and a pipe having an outlet port 28. The cofferdam sinks into a groove and further under the bottom of seawater by the tare weight.
