REPAIR MEMBER AND REPAIR METHOD FOR EXISTING HOLLOW TUBE
PROBLEM TO BE SOLVED: To provide a repair member for an existing hollow tube that enables a bottom part of the existing hollow tube to be repaired without welding and/or fusion cutting at a work site.SOLUTION: A repair member 1 for an existing hollow tube is interposed between a cut edge 8a formed near a bottom part of the existing hollow tube 8 and a concrete foundation 20 in which a bottom end of the existing hollow tube 8 is embedded. The repair member includes a first cylindrical body 4 disposed to cover an outer side surface near the cut edge 8a, a flat plate body 5 connected integrally with a bottom end of the first cylindrical body 4, and covering an opening 9a of a cut mark hole 9 formed on the concrete foundation 20, and a second cylindrical body 6 connected integrally to an undersurface side 5b of the flat plate body 5 and hanging inside the cut mark hole 9. The flat plate body 5 has a through-hole 7 connecting a hollow part of the first cylindrical body 4 with a hollow part of the second cylindrical body 6. A body part 2 formed integrally by the first cylindrical body 4, the flat plate body 5 and the second cylindrical body 6 comprises a pair of split pieces 3, 3 made by splitting the body part 2 in a vertical direction.SELECTED DRAWING: Figure 1
【課題】作業現場において溶接及び／又は溶断作業を行うことなく既存中空管の根元を補修できる既存中空管補修部材を提供する。【解決手段】既存中空管８の根元近傍に形成される切断端８ａと、既存中空管８の下端が埋設されるコンクリート基礎２０と、の間に介設される既存中空管補修部材であって、切断端８ａ近傍の外側面を被覆しながら配される第１の筒体４と、この第１の筒体４の下端に一体に接合され、コンクリート基礎２０に形成される切断跡穴９の開口部９ａを塞ぐ平板体５と、この平板体５の下面側５ｂに一体に接合され、切断跡穴９内に垂下する第２の筒体６とを有し、平板体５は、第１の筒体４の中空部と、第２の筒体６の中空部とをつなぐ貫通孔７を備え、第１の筒体４と平板体５と第２の筒体６が一体化されてなる本体部２は、この本体部２を鉛直方向に二分割してなる一対の分割片３，３からなる既存中空管補修部材１による。【選択図】図１
