TUNNEL REHABILITATION METHOD, REHABILITATION TUNNEL STRUCTURE AND CONNECTING DEVICE
To provide a tunnel rehabilitation method and a rehabilitation tunnel structure capable of adjusting a position of a rehabilitation pipe after pipe production when rehabilitating an existing tunnel by a rehabilitation pipe.SOLUTION: A lining of an existing tunnel is removed until at least an outer peripheral support 2 is exposed. A rehabilitation pipe 3 is manufactured in an underground space after the removal. The rehabilitation pipe 3 and the outer peripheral support 2 are connected by a connecting device 10 capable of adjusting a gap between connection objects. An annular gap 1d on the outer peripheral side of the rehabilitation pipe 3 is filled with a backfill material 5.SELECTED DRAWING: Figure 1
【課題】既設トンネルを更生管によって更生する際に、製管後の更生管を位置調整可能とするトンネル更生方法及び更生トンネル構造を提供する。【解決手段】既設トンネルの覆工を、少なくとも外周支保工２が露出されるまで撤去する。撤去後の坑内空間に更生管３を製管する。連結対象間の間隔を調節可能な連結装置１０によって、更生管３と外周支保工２とを連結する。更生管３の外周側の環状間隙１ｄには、裏込め材５を充填する。【選択図】図１
