HOLLOW CYLINDRICAL STRUCTURE AND HOLLOW CYLINDRICAL STRUCTURE REINFORCING METHOD
PROBLEM TO BE SOLVED: To provide a hollow cylindrical structure reinforcing method which wholly and properly presses a cylindrical reinforcing part which is arranged in an inside hollow part of a hollow cylindrical structure to an inside wall face which surrounds the inside hollow part of the hollow cylindrical structure by a liquid hardener and compressed air, and properly reinforces the hollow cylindrical structure by using the reinforcing part and the liquid hardener.SOLUTION: A hollow cylindrical structure 1 comprises: a working hole 9 which is formed at a sidewall of the hollow cylindrical structure; a reinforcing part 3 which is inserted into an inside hollow part of the hollow cylindrical structure 1 from the working hole 9, and surrounds an inside balloon part 2; a liquid hardener 4 which is injected into a side of a bottom of the inside hollow part of the inside balloon part 2 from the working hole 9; and compressed air 5 which is injected to a side of a head of the sealed inside hollow part of the inside balloon part 2 from the working hole 9. A side of the bottom of the reinforcing part 3 is pressed against an inside wall face which surrounds the inside hollow part of the hollow cylindrical structure 1 by the inside balloon part 2 which is expanded by the liquid hardener 4, and a side of a head of the reinforcing part 3 is pressed against the inside wall face which surrounds the inside hollow part of the hollow cylindrical structure 1 by the inside balloon part 2 which is expanded by the compressed air 5.SELECTED DRAWING: Figure 1
【課題】中空筒状構造物の内側空洞部に配置した筒状の補強部が全体的に液状硬化材と圧縮空気とで中空筒状構造物の内側空洞部を囲む内壁面に適切に押し付けられ、中空筒状構造物が補強部と液状硬化材とで適切に補強される。【解決手段】中空筒状構造物１の側壁部に設けられた作業孔部９と、作業孔部９から中空筒状構造物１の内側空洞部に挿入されかつ内側風船部２を囲む補強部３と、作業孔部９から内側風船部２の内側空洞部の底部の側に注入された液状硬化材４と、作業孔部９から内側風船部２の密閉状になった内側空洞部の頭部の側に注入された圧縮空気５とを備え、補強部３の底部の側が液状硬化材４で膨張した内側風船部２により中空筒状構造物１の内側空洞部を囲む内壁面に押し付けられ、補強部３の頭部の側が圧縮空気５で膨張した内側風船部２により中空筒状構造物１の内側空洞部を囲む内壁面に押し付けられている。【選択図】図１
