PENETRATION RESISTANCE REDUCTION DEVICE AND PENETRATION METHOD FOR SUCTION STRUCTURE
To provide a penetration resistance reduction device and a penetration method for a suction structure which can reduce penetration resistance of a skirt part without installing a configuration for countermeasures against penetration resistance reduction in a suction foundation structure.SOLUTION: A penetration resistance reduction device 1 for reducing penetration resistance of a cylindrical skirt part 13 when a suction structure 10 having the skirt part 13 is penetrated into a water bottom ground using an inside-and-outside pressure difference (suction) of the skirt part 13 by discharge water includes a lubricant spray pipe 2 buried in a water bottom surface X in a state of being wound along the outer peripheral surface of the skirt part 13, and a lubricant supply device 3 for supplying a lubricant material L to the lubricant spray pipe 2, wherein in the lubricant spray pipe 2, spray holes 21 for spraying the lubricant material L onto the water bottom surface X are formed at such intervals as to evenly spread to the water bottom surface X where the lubricant material L is brought into contact with the outer peripheral surface of the skirt part 13.SELECTED DRAWING: Figure 1
【課題】サクション基礎構造体に貫入抵抗低減対策用の構成を設けることなく、スカート部の貫入抵抗を低減できる貫入抵抗低減装置及びサクション構造体の貫入方法を提供する。【解決手段】筒状のスカート部１３を備えたサクション構造体１０を、排水によるスカート部１３の内外圧力差（サクション）を用いて水底地盤に貫入させる際の、スカート部１３の貫入抵抗を低減させる貫入抵抗低減装置１であって、スカート部１３の外周面に沿って巻き回された状態で水底面Ｘに沈設された滑剤散布管２と、滑剤散布管２に滑材Ｌを供給する滑材供給装置３と、を備え、滑剤散布管２には、滑材Ｌを水底面Ｘに散布する散布孔２１が、滑材Ｌがスカート部１３の外周面に接する水底面Ｘに満遍なくいきわたる間隔で形成されている。【選択図】図１
