Separating simple trolley modeling construction device for large-section tunnel second-lining arc wall in metro running section

The utility model discloses a separating simple trolley modeling construction device for a large-section tunnel second-lining arc wall in a metro running section and belongs to the technical field of metro construction. The separating simple trolley modeling construction device for the large-section tunnel second-lining arc wall in the metro running section mainly comprises a tunnel inverted arch, a tunnel side wall and a tunnel arch part. An inverted arch modeling device mainly comprises an arc-shaped steel formwork, positioning tie bars, positioning anchor bars, square supporting timber, horizontal supporting steel pipes, connecting bolts, and adjustable U-shaped top supports. The arc-shaped steel formwork is fixed to the positioning tie bars and the positioning anchor bars through the bolts and is fastened by means of the square supporting timber and the horizontal supporting steel pipes through the adjustable U-shaped top supports at the position of an upper opening of the modeling plates. The formwork is connected through the connecting bolts in the longitudinal direction. A side wall modeling device comprises a triangular support, a set-shaped steel formwork, horizontal longitudinal back bars, ground anchor pull rods, horizontal supporting steel pipes, connecting bolts, and adjustable U-shaped top supports. An arc part modeling device comprises a simple trolley, an arc-shaped steel formwork, a steel rail, sleepers, and a steel support. According to the separating simple trolley modeling construction device for the large-section tunnel second-lining arc wall in the metro running section, working efficiency is improved greatly, labor is saved, and the purpose of safe and rapid construction is realized.
