COOLING APPARATUS AND COOLING METHOD FOR CONCRETE STRUCTURE

To cool a concrete structure while maintaining a water cement ratio.SOLUTION: A cooling apparatus 100 includes: an outer pipe 10 embedded in a concrete structure 1 in a state where its one end is used as a closed end 10a and its other end is used as an opened end 10b; an inner pipe 20 which is separated from the closed end 10a of the outer pipe 10 and is inserted into the outer pipe 10, and forms a passage 40 between an inner peripheral surface of the outer pipe 10 and the inner pipe; and a ventilator 30 which feeds air into the passage 40 through the inner pipe 20 or sucks air from the passage 40 through the inner pipe 20, and cools the concrete structure 1.SELECTED DRAWING: Figure 2 【課題】水セメント比を保ちつつコンクリート構造物を冷却する。【解決手段】冷却装置１００は、一端を閉塞端１０ａとし他端を開放端１０ｂとした状態で前記コンクリート構造物１に埋設された外管１０と、外管１０の閉塞端１０ａから離隔して外管１０に挿入され、外管１０の内周面との間に通路４０を形成する内管２０と、内管２０を通じて通路４０に空気を送り込み、又は内管２０を通じて通路４０から空気を吸引し、コンクリート構造物１を冷却する通風器３０と、を備える。【選択図】図２
