EARTHQUAKE RESISTANT STRUCTURE IN CONNECTION PART OF MANHOLE SIDEWALL AND PIPE
PROBLEM TO BE SOLVED: To smoothly execute an expansion in an expansion part of an earthquake resistant joint, by executing breaking of thin mortar of a backup material side surface in the whole periphery of a rehabilitation pipe, in an earthquake resistant structure that is composed of the rehabilitation pipe for lining by being inserted into a pipe of an existing pipe connected to a manhole sidewall, a flange part fastened by being applied to an inside surface of the manhole sidewall, a tubular part fastened by being out-fitted to a pipe end part of the rehabilitation pipe of projecting from the existing pipe, a flexible earthquake resistant joint having an expansion part formed between the flange part and the tubular part, an expandable ring-shaped backup material installed around the pipe end part of the rehabilitation pipe adjacently to the expansion part of the joint, and mortar placed by covering the earthquake resistant joint and the backup material, and that thins the mortar for covering a backup material side surface.SOLUTION: The edge of upper-lower mortars is cut in an invert 54 adjacent to thin mortar 43a, and the mortar and a nonadhesive sheet 47 are buried, and a motor surface layer part 58 on the sheet is easily separated.SELECTED DRAWING: Figure 7
【課題】マンホール側壁に接続される既設管の管内に挿入してライニングされる更生管と、マンホール側壁の内側面に当てられて止着されるフランジ部と、既設管より突出する更生管の管端部に外挿されて止着される管状部と、前記フランジ部と管状部との間に形成される伸縮部を備えた可撓性のある耐震継手と、該継手の伸縮部に隣接して前記更生管の管端部の周りに装着される伸縮性のあるリング状のバックアップ材と、耐震継手及びバックアップ材を覆って打設されるモルタルよりなり、バックアップ材側面を覆うモルタルを薄肉とした耐震構造において、厚生管の全周においてバックアップ材側面の薄肉モルタルの破壊が行われ、耐震継手の伸縮部での伸縮が支障なく行えるようにする。【解決手段】薄肉モルタル43aに隣接するインバート54に上下のモルタルを縁切りする、モルタルと非接着性のシート47を埋設し、シート上のモルタル表層部58を剥離し易くする。【選択図】図7
