Abstract

PURPOSE: To ensure that soil and stones can be cast and deposited at a predetermined place even where the depth of water and tidal current velocity are greater by adjusting the depth of a chute capable of extending and contracting from a float toward the ground the use of a drive mechanism.
CONSTITUTION: With cables 7 let off by operating winches 10 on a soil carrier boat 1, a chute 5 is extended toward the ground 12. With the lower end of the chute 5 located near the ground 12, a hydraulic cylinder 3 is extended to open the bilge. Becuase soil and stones 11 in the hold 2 is discharged downward while guided by the chute 5, the soil and stones 11 is prevented from diffusing and scattering, and can be deposited at a desired fall place on the ground 12. Even when the chute 5 tends to vibrate under the influence of a tidal current or the like, it is kept in extended state by a chute holding mechanism H consisting of weights 6, cables 7, and winches 10.
