A ASSIST DEVICE FOR REFLOATING OF CONCREAT STRUCTURE IN THE SEA

摘要

An assisting device for refloating of a concrete structure in the sea installed under water stably refloats a concrete block constituting bases of a structure in the sea such as a wharf, a breakwater, or the like when the concrete block is discarded, and comprises an anchor rod(9) inserted into a fixing groove(8) formed in a concrete structure in the sea to quickly and stably perform a reinstallation work and a recollection work. The assisting device for refloating of a concrete structure in the sea comprises: the fixing groove(8) having a funnel shape wherein the diameter of the fixing groove gets wider from an inlet to the inside of the fixing groove; a screw coupling part(10) with which a fixing anchor(4) having a coupling hole(3) is coupled wherein a refloating wire(5) is coupled with an upper end of the coupling hole; and an expansion unit wherein the diameter of the expansion unit gets wider from an upper end to a lower end.
