Counter-force frame of circular shaft shield tunneling machine

The utility model relates to the technical field of reaction frames, in particular to a circular shaft shield tunneling machine reaction frame which comprises a supporting frame, the bottom end of the supporting frame is fixedly connected with a supporting plate, the surface of the supporting frame is fixedly connected with a first connecting column and a second connecting column, and the outer surface of the supporting frame is fixedly connected with a cross beam. The surface of the cross beam is fixedly connected with a connecting beam, and the surface of the cross beam is fixedly connected with a supporting base. The integrated counter-force frame is manufactured and acts in the ultra-deep round well, the problems of shield starting counter-force and segment assembly in the ultra-deep round well are effectively solved, it is guaranteed that a shield tunneling machine smoothly starts tunneling in a round working well, and under the connection of the rotary column and the adjusting screw rod, through the con
