The invention discloses a horizontal layered surrounding rock tunnel construction lining formwork trolley which comprises a moving mechanism, a lifting mechanism and a bearing mechanism, the moving mechanism comprises a plurality of driving blocks, the driving blocks are symmetrically arranged, guide rails are slidably connected to the inner sides of the driving blocks, and after current tunnel section lining is completed, the lifting mechanism is driven by the guide rails to move to the lifting mechanism. When a next to-be-lined tunnel section is moved, the side plates located on the two sides are moved back to the safe position through the second hydraulic telescopic cylinders, the first hydraulic telescopic cylinders are opened to drive the lifting frame, the top frame, the supporting columns and the top plate to descend to the positions where the lifting frame, the top frame, the supporting columns and the top plate are disengaged from the inner wall of the tunnel, and then the limiting nails are pried aw
