Tunnel arch ring and cable groove side wall integrated secondary lining telescoping steel form

Abstract

The invention discloses a tunnel arch ring and cable groove side wall integrated secondary lining telescoping steel form which comprises a portal system, a connecting system and a panel system. The portal system comprises a beam, supporting legs, inclined supports and vertical columns, the connecting system comprises a spandrel connecting lead screw, a cross support lead screw, a horizontal oil cylinder, an arch springing connecting lead screw, an inclined support lead screw, a lifting lead screw and an outer supporting lead screw, and the panel system comprises an arc-shaped panel and a cablegroove side wall panel. The tunnel arch ring and cable groove side wall integrated secondary lining telescoping steel form effectively solves the problems that tunnel arch ring secondary lining concrete and cable groove side wall concrete are constructed by two processes, treatment processes of the combined surface new and old concrete are decreased, involvement of labor and formwork resources issaved, one-time pouring tunnel arch ring and two-side cable groove side wall concrete is completed, pouring quality of the cable groove side wall concrete is controlled, construction schedule is accelerated, the telescoping steel form is reliable in technique and simple in process, quality is ensured, and the good economic benefits are achieved.

Description

technical field [0001] The invention relates to the construction field of concrete for the second lining of the arch ring in the tunnel hole of the expressway project and the hydropower project and the concrete for the side wall of the cable trench on both sides of the tunnel, in particular to a steel mold trolley for the second lining integrated with the tunnel arch ring and the side wall of the cable trench. Background technique [0002] The current expressway projects and hydropower projects mostly involve tunnel construction. When pouring the second lining concrete in the tunnel, the conventional second lining steel mold trolley is used for pouring. The steel panels of the second lining trolley are curved panels. There is a cable trench, and the structure of the cable trench is a vertical side wall, and the side wall is equipped with a square cap. The conventional two-lined trolley curved panel cannot meet the synchronous one-time construction requirements of this structu...
