METHOD FOR LEVELLING UNDERWATER RUBBLE MOUND FOUNDATION SLOPE AND WEIGHT THEREOF

摘要

PROBLEM TO BE SOLVED: To make it possible to mechanically, efficiently and simply level the extra-banking slope of an underwater rubble mound foundation according to a planned gradient of slope.;SOLUTION: An underwater rubble mound foundaion slope leveling weight erects a steel pipe 9 and covering bodies 10 surrounding the steel pipe 9 at required intervals on the upper surface of the bottom plate 11 to fix and, at the same time, a weight head A filling the insides of the steel pipe 9 and covering bodies 10 with heavy object Wb such as sand, iron sand, etc., is fixed to the lower end of a hollow casing B. Then, in the case the weight head A is suspended to a hanging wire through the hollow casing B, an angle of inclination of the bottom plate 11 is so formed that it coincides with the gradient of a previously planned slope Ca of an underwater rubble mound foundation C.;COPYRIGHT: (C)2000,JPO
