JOINT DEVICE FOR SEWERAGE MAIN PIPE CONNECTING WITH MANHOLE, AND CONSTRUCTION METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide a joint device for a sewerage main pipe that can exhibit secure base isolation effect against ground change of an earthquake etc., and also prevent ground water from flowing in a manhole.SOLUTION: Gaps 12, 22 are formed by grinding a manhole peripheral wall 10 on an outer peripheral side part of a sewerage main pipe 11, and a joint device is fitted to the gaps 12, 22. The joint device comprises a ring body 1 and elastic packings 2, 3; the ring body 1 is arranged on an inner peripheral side of the ground hole 12 and has a ring length long enough to include the sewerage main pipe 11 deep, and the elastic packings 2, 3 are arranged to the perimeter of an inner peripheral part of the ring body 1 and the perimeter of an outer peripheral part, respectively, the elastic packing 2 on the inner peripheral side being arranged over the perimeter between the ring body 1 and sewerage main pipe 11, and the elastic packing 3 on the outer peripheral side being arranged over the perimeter between the ring body 1 and manhole peripheral wall 10.SELECTED DRAWING: Figure 1
【課題】 本発明は、地震等の地盤変化に対して確実な免震効果を発揮するとともに、マンホール内への地下水の流入を防止できる下水道本管の継手装置を提供することにある。【解決手段】 下水道本管１１の外周側部のマンホール周壁１０を削り空隙１２，２２を設け、その空隙１２，２２に取り付ける継手装置であって、環体１と弾性パッキン２，３を備えており、環体１は、削孔１２の内周側に配置してあり、下水道本管１１を深く呑み込む環の長さを有し、弾性パッキン２，３は、環体１の内周部の全周と外周部の全周にそれぞれ配置してあり、内周側の弾性パッキン２は、環体１と下水道本管１１の間の全周に亘って配置してあるとともに、外周側の弾性パッキン３は、環体１とマンホール周壁１０との間の全周に亘って配置してあることを特徴とする。【選択図】 図１
