Abstract

PURPOSE: To let a weight drop at a correct spot and level off a prearranged place satisfactorily by providing spuds at the both ends of a ground contacting body in a vertically movable manner.
CONSTITUTION: After dumping ripraps at the water bottom where the riprap foundation is to be built, a weight guide frame 1 is lowered by means of a crane, etc. at one spot of a riprap foundation erection area 17. At that time, spuds 101, 102 which put out from the lower surface of the ground contacting body 9 are introduced way into between the ripraps 16. Then the weight 3 is lowered to strike the riprap 16. Following this procedure, measurement is made by a scale 8 aboard a working large 7, etc. When the weight 3 has reached a prearranged water depth, one of the wires 15 fixed to arms 141, 142 is pulled, so that the guide frame 1, changes the ground contacting position of the ground contacting body 9 centering around spud 101 thrusted into the ripraps. As a result, the lower surface of the weight 3 is placed in an opposed position to a new riprap part. Thus it is possible to perform the underwater riprap foundation at high operating rate with the minimized operation volume.
