SALT DAMAGE SUPPRESSION APPARATUS AND SALT DAMAGE SUPPRESSION METHOD FOR CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a salt damage suppression apparatus and a salt damage suppression method for a concrete structure that can efficiently and uniformly sprinkle water over a concrete-made upper construction body lower surface side, and efficiently remove salt damage factors.SOLUTION: A salt damage suppression apparatus comprises: a water sprinkling unit 11 which has one or a plurality of nozzles 10, 10, ... having injection ports directed obliquely upward, and is arranged on a lower surface side of a floor slab part 7; a water supply unit 12 which supplies water to the sprinkling unit 11; driving means of moving the sprinkling unit 11 upward and downward. Water is sprinkled from the nozzles 10, 10 to wash away salt damage factors sticking on a reinforced concrete-made upper construction body 5 having column coupling parts 6, 6 coupled to column heads 4, and the floor slab part 7.SELECTED DRAWING: Figure 1
【課題】コンクリート製の上部工体下面側に対し効率良く均等に水を散布でき、塩害因子を洗浄によって効率良く除去することができるコンクリート構造物の塩害抑制装置及び塩害抑制方法の提供。【解決手段】噴射口を斜め上に向けた１又は複数のノズル１０，１０...を有し、床版部７の下面側に配置された散水ユニット１１と、散水ユニット１１に水を供給する給水ユニット１２と、散水ユニット１１を上下移動させる駆動手段とを備え、ノズル１０，１０より散水し、支柱頭部４に連結される柱連結部６，６及び床版部７を有してなる鉄筋コンクリート製の上部工体５に付着した塩害因子を洗浄により除去する。【選択図】図１
