In the transmitted die sea area control structure and its construction

摘要

PROBLEM TO BE SOLVED: To provide a structure for controlling a permeable sea area and a construction method thereof always having enough wave dissipating performance against waves and capable of reducing acting wave power at the time of storm wind.;SOLUTION: A structure for controlling a permeable sea area 1 is installed with a box type dam body 2 at a pile foundation 3 in an appropriate gap 5 between a bottom of the sea 4 and the dam body 2 is comprised of a front surface wall composed of a vertical wall 6 and a tilt wall 7, an intermediate wall 12, a rear surface wall 9, a side surface wall 8, a bottom plate 10 and a top plate 11. A permeable slit 15 is opened at the vertical wall 6 and the tilt wall 7, the intermediate wall 12 and the rear surface wall 9, an opening part 16 is formed at the bottom plate 10 and the top plate 11, and the permeable slit 15 of the tilt wall 7 is opened at the upper part of the permeable slit 15 and at a place opposite to the upper wall surface of the intermediate wall 12.;COPYRIGHT: (C)2008,JPO&INPIT
