REPAIR MATERIAL FOR CYLINDRICAL PART, UNDERGROUND DRAINAGE FACILITY PROVIDED WITH THE SAME, AND REPAIR METHOD FOR CYLINDRICAL PART
PROBLEM TO BE SOLVED: To provide a repair material for a cylindrical part that allows a deteriorated or damaged part of the cylindrical part to be easily repaired regardless of the location thereof, along with an underground drainage facility provided with the repair material and a repair method for the cylindrical part.SOLUTION: A repair material 1 includes: a first annular member 2 inserted into a cylindrical part 52 such that a first hole part 10 is positioned on an invert flow channel 56; a standing pipe 4 having a cylindrical body 40, a flexible seal member 44 protruding outward from the cylindrical body 40 in a radial direction and having an outer diameter greater than an inner diameter of the cylindrical part 52, and a support member 41 having a protruded length shorter than a protruded length of the seal member 44 and supporting the seal member 44 when the seal member 44 is deflected in an axial direction of the cylindrical body 40, the standing pipe being laid out on the first annular member 2 such that a second hole part 45 is positioned on the first hole part 10; mortar 5 filled in a space partitioned by an inner peripheral surface of the cylindrical part 52 and the standing pipe 4; and a cover 6 covering an opening at a top of the cylindrical body 40.SELECTED DRAWING: Figure 1
【課題】筒部の劣化箇所または破損箇所によらずに当該筒部を容易に補修することが可能な筒部の補修部材、それを備えた地下排水施設、および筒部の補修方法を提供する。【解決手段】補修部材１は、インバート流路５６の上に第１孔部１０が位置するように筒部５２に挿入される第１環状部材２と、筒体４０と、筒体４０から径方向の外方に突出し、筒部５２の内径よりも大きい外径を有する可撓性のシール部材４４と、突出長さがシール部材４４の突出長さよりも短く、シール部材４４が筒体４０の軸方向に撓むときにシール部材４４を支える支持部材４１とを有し、第２孔部４５が第１孔部１０の上に位置するように第１環状部材２上に配置される立管４と、筒部５２の内周面と立管４とにより仕切られた空間に充填されたモルタル５と、筒体４０の上方の開口を覆う蓋６とを備えている。【選択図】図１
