The utility model provides a subway shield constructs construction shield structure machine system of missing stop. The system of missing the stop includes that clamping rail advancing device, vertical jacking device, guide rail, shield construct quick -witted bracket, hydraulic power unit and guide rail removal hoist engine, contacts through the direction slider between bottom that the shield constructs quick -witted bracket and two closed slides, clamping rail advancing device is by left and right fluid pressure type clamping rail ware and fixes respectively that left and right thrust cylinder constitutes on left and right fluid pressure type clamping rail ware, and the centre gripping is on the shield constructs two guide rails of quick -witted bracket tail end to two fluid pressure type clamping rail wares respectively, and two thrust cylinder's piston end constructs quick -witted bracket trailing end connection through round pin axle and shield respectively, vertical jacking device be by the welding before the shield constructs the quick -witted shield body, four of back position both sides shore piece and place in every jacking cylinder under shoring the piece and form. The utility model discloses simple structure, construction convenience, the security is high, has shortened the time of missing the stop greatly, has improved the speed of missing the stop for the construction progress, reduced construction cost, saved manpower and materials.
