Tunnel lining double-trolley combination device and integral pouring construction method

The invention provides a tunnel lining double-trolley combination device and an integral pouring construction method. Anti-collision beams are fixed to the two sides of the top faces of two trolley door beams correspondingly, trolley splicing main cross beams are distributed on the top faces of the trolley door beams, and bench platforms are fixed to the anti-collision beams; arch frame horizontal cross beams are arranged on the trolley splicing main cross beam and the bench platform above the trolley door beam in the transverse direction, vertical I-shaped steel is fixedly distributed at the upper ends of the arch frame horizontal cross beams in the transverse direction, the upper ends of the vertical I-shaped steel are fixedly connected with the annular arch frame, and the vertical I-shaped steel is further fixedly connected with an original trolley vertical supporting frame through longitudinal channel steel. The problems that according to existing large-section tunnel double-trolley construction, the dist
