PURPOSE:To uniformly lay an object under the ground in water without resorting to divers by a method in which water is supplied through hoses to plural outlets provided to the side of an object to be buried to spray water jet stream onto the soil and sand below the object on the bottom in water for scattering them. CONSTITUTION:Water is sent to water jet nozzles 8 provided to an object 4 to be buried on the bottom in water through hoses 3 from a pump 2 on a barge 1 and water jet stream from the nozzles 8 is sprayed onto soil and sand below the object 4 for scattering. In this case, a level meter is attached to the surface of the object 4 to be buried, and while watching the burying level by a level detector, the amount of water to send to each nozzle is adjusted to equalize the burying depth of the object 4. |
