METHOD OF REPAIRING AND REINFORCING SUBMARINE CONCRETE CONSTRUCTIONS

摘要

A repair and reinforcement method of an underwater concrete structure is provided to increase the durability and the supporting force of a base foundation by increasing the coating thickness of the base foundation. A repair and reinforcement method of an underwater concrete structure comprises: a process of partitioning the installation position of a rail guide in a vertical direction at constant intervals at the outer circumference of a base foundation(1); a process of fixing and installing a plurality of rail guides(2) at the sites, which are vertically partitioned on the outer circumference of the base foundation, using an anchor bolt; a process of surveying a scour part(11) formed in the base foundation; a process of determining a range to repair and manufacturing an adhering plate corresponding to the range; a process of fixing and arranging reinforcing bars using an anchor; a process of setting up the adhering plate on the scour part which needs repair; a process of making a hole on the adhering plate positioned on the scour part and connecting hoses of a grouting pump; and a process of charging grout materials in the repaired part using the grouting pump.
