Abstract

The invention provides a mounting and lifting method for a movable formwork for bridge construction and relates to the technical field of highway and railway bridge construction. The method aims at the movable formwork for conducting bridge construction. The movable formwork comprises rear main supporting legs, rear guiding beams, main beams, front guiding beams, front main supporting legs, main beam head connecting sections, main beam tail connecting sections, hung external ribs, an external formwork system and an internal formwork system. Stabilizing supporting rods are fixedly mounted at the front ends and the rear ends of the main beams correspondingly. The mounting and lifting method for the movable formwork for bridge construction comprises the following steps that 1, the movable formwork is spliced on ground and prepares to be lifted; 2, the rear guiding beams are jacked and pushed in place; 3, the front guiding beams are jacked and pushed in place; and 4, main beam butt joint is conducted, the formwork is arranged in place, and casting for beam manufacturing is prepared. The mounting and lifting method is suitable for mounting and constructing of the highway-and-railway co-built-section high-pier and super-wide-pier movable formwork, the formwork can be mounted in place only through one-time lifting, the occupied site for lifting and mounting is small, and the problem that the construction site is limited is effectively solved.

Description

Technical field: [0001] The invention relates to the technical field of road and bridge construction, in particular to a method for installing and lifting a mobile formwork for bridge construction. Background technique: [0002] Some of the main pier heights of the road-rail dual-purpose bridge are more than 58m, and the lateral pier width of the transverse bridge is more than 33.6m. It is quite difficult to install between the two pier heights of more than 58m using the existing technology. The existing mobile formwork Safe, economical and effective installation cannot be carried out under such working conditions. Invention content: [0003] In view of this, it is necessary to provide a method for installing and lifting mobile formwork for bridge construction. [0004] A method for installing and lifting a mobile formwork for bridge construction, the method is a method for bridge construction with a mobile formwork, the mobile formwork includes a rear main leg, a rear gu...
