Stuck machine extricating method for TBM during tunnel construction

The invention discloses a stuck machine extricating method for a TBM during the tunnel construction. The stuck machine extricating method comprises (1) excavating a vertical pilot tunnel manually, and excavating a pipe shed work cell by avoiding the collapse influence area; (2) constructing a lead pipe shed towards the collapse influence area reversely; (3) excavating the collapse influence area in front of a cutterhead manually; (4) excavating collapse zones on the tops of the cutterhead and a shield through the small vertical pilot tunnel; (5) cleaning collapsed slag around the cutterhead (10) and the shield (1), and then extricating the TBM. The stuck machine extricating method for the TBM during the tunnel construction is advantaged in that the stuck machine extricating method is quick and convenient, and is high in safety and has few construction steps; The method for extricating the TBM can be operated safely, and can extricate the stuck TBM within very short time, and cost and time are saved. 本发明公开了种TB
