Construction method of marine structures

PROBLEM TO BE SOLVED: To provide a construction method for a marine structure capable of improving productivity and workability. SOLUTION: A construction method for a pier 1 includes: an arrangement step in which a plurality of permanent forms 13 are arranged in the area excluding a beam forming area R on a base plate 11 of a precast panel 10; and an installation step in which concrete is placed on the beam forming area R that appears between the plurality of permanent forms 13 arranged on the base plate 11 and on the plurality of permanent forms 13 themselves, which comprises a beam 6 and a slab 7 joined to a plurality of pile heads 2a. In this way, a superstructure 3 having the beam 6 and the slab 7 is formed by preparing the plurality of permanent forms 13 and the precast panel 10, by arranging the plurality of permanent forms 13 on the base plate 11 of the precast panel 10, and by placing concrete on the base plate 11, which prevents from making and assembling a burial mould in a complex shape and improves productivity and workability.
