Document Type and Number:
Japanese Patent JP6503951
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent extraction caused by an excessive external force without increasing the size of a suction anchor.SOLUTION: A suction anchor extraction prevention system 1 comprises: a drainage pump 10 that communicates with and is connected to an internal space of a suction anchor 2; a weight meter 7 as measurement means for measuring a tensile force generated at a tension cable 5; and an operation control device 8 as operation control means for controlling activation of the drainage pump 10. The operation control device 8 determines whether or not the tensile force measured by the weight meter 7 has exceeded or can exceed a predetermined allowable tensile force and, when the tensile force has exceeded or can exceed the predetermined allowable tensile force, activates the drainage pump 10 so that water spreading in the internal space of the suction anchor 2 is drained away.SELECTED DRAWING: Figure 1
