As is clear from the above description, the weight of the present invention is constructed by filling a heavy object into a steel pipe and a cover made of steel plate, which are fixed to a bottom plate made of extra-thick steel plate, to form the weight body.
Furthermore, by inserting a weight pack or extra-thick steel plate into the casing formed on the outer periphery of the cover, the center of gravity is located downward, and depending on the water depth, other steel pipes can be added to the above steel pipe to increase the height. Even if the weight is used as a weight plate, the center of gravity becomes higher as the support frame becomes taller, or the buoyancy increases, as in the case of the above-mentioned weight, which has a tower-shaped support frame made of steel on a weight plate. Therefore, when vertically moving underwater, it always moves vertically without fear of lateral vibration, and can produce the desired constriction effect. Moreover, by appropriately changing the weight pack or extra-thick steel plate that can be freely inserted and removed from the casing, the weight can be made to suit the site. It is convenient for transportation because it can be separated from the
