WATER AREA STRUCTURE, AND METHOD OF CONSTRUCTING WATER AREA STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To provide a water area structure which includes a steel pipe sheet pile well as a foundation, has imparted thereto characteristics of low uprush height, low overtopping wave amount, low reflection, etc. exhibits high quality, and can be constructed in a dry construction method, and to provide a method of constructing the same. PSOLUTION: According to the method of constructing the water area structure, a steel pipe sheet pile (front side) 3, a steel pipe sheet pile (rear side) 5, and steel pipe sheet piles (partition wall) 51 are driven into the ground 27, then they are jointed together, and a lower floor slab 9 (top slab concrete) is poured in the well to set timbering 53, followed by dewatering the interior of the well to dry up the same. Subsequently a wave dissipating structure (slit column bodies 11, breakwater walls 13, upper floor slabs 15, etc.) is constructed, and removal of the timbering 53, underwater cutting of the steel pipe sheet pile (front side) 3 are carried out, to thereby achieve foot protection. By carrying out the above steps, the water area structure 1 is constructed. PCOPYRIGHT: (C)2007,JPO&INPIT
