REINFORCEMENT METHOD FOR HOLLOW CYLINDRICAL STRUCTURE
PROBLEM TO BE SOLVED: To provide a method that facilitates reinforcement of a hollow cylindrical structure.SOLUTION: A reinforcement method for a hollow cylindrical structure comprises the following steps for: forming a work hole 2 at a height from a site 3 that does not use a vehicle for high lift work; inflating an inner balloon part 14 with compressed air and fixing a reinforcing part 12 on an inner wall surface surrounding an inner hollow part of a hollow cylindrical structure 1 with an adhesive, the inner balloon part having been pulled into and lifted in the inner hollow part of the hollow cylindrical structure 1 through the work hole 2 from outside the hollow cylindrical structure 1; inflating a carry-in balloon part 32 of a second upper carry-in device 31 with compressed air and installing the balloon part at a head part side of the inner hollow part; inserting a curable material pipe into the inner hollow part of the inner balloon part with a hoisting apparatus 36 of the second upper carry-in device; and casting a liquid curable material into the inner hollow part of the inner balloon part from the curable material pipe 41 so as to be filled starting from a bottom part.SELECTED DRAWING: Figure 4
【課題】中空筒状構造物を補強する工法がやりやすい。【解決手段】作業孔部２が高所作業車を使用することのない現場３からの高さに設けられ、中空筒状構造物１の外部から作業孔部２を経由して中空筒状構造物１の内側空洞部に引き上げられた内側風船部１４が圧縮空気で膨張されて補強部１２を中空筒状構造物の内側空洞部を囲む内壁面に接着剤で固定した後、第２上部搬入装置３１の搬入風船部３２が圧縮空気で膨張して内側風船部１４の内側空洞部の頭部の側に設置され、この設定された第２上部搬入装置３１の吊り上げ用具部３６により硬化材パイプ部が内側風船部の内側空洞部に挿入され、液状硬化材が硬化材パイプ部４１から内側風船部の内側空洞部に下部から埋め込まれるように打設される。【選択図】図４
