Simply supported structure bridge horizontal swivel construction system and method

Abstract

The invention discloses a simply supported structure bridge horizontal swivel construction system and a simply supported structure bridge horizontal swivel construction method. The system comprises a beam body, two bridge piers, at least one temporary pier, a slide way beam and a pushing device, wherein the beam body is provided with a fixed end and a movable end; the two bridge piers comprise a first bridge pier and a second bridge pier; the fixed end is supported on the first bridge pier; a rotary supporting seat is arranged below the fixed end; one end of the slide way beam is supported onthe temporary pier, and the other end of the slide way beam is supported on the second bridge pier; the movable end is supported on the slide way beam; and the pushing device is arranged on the slideway beam. During horizontal swivel construction, the pushing device pushes the movable end to slide on the slide way beam so as to push a beam body to a design position; because the beam body has thesame stress condition as that of a design operation stage, the method is suitable for construction of various bridges and has high universality; meanwhile, the system and the method have the advantages of low requirement on sites, short sliding distance of the movable end of the beam body and less construction of a temporary structure.

Description

【Technical field】 [0001] The invention relates to a simply-supported structure bridge translation construction system and a translation construction method thereof. 【Background technique】 [0002] When the bridge spans railways, highways, and rivers, due to the influence of the passage clearance, waterway and terrain under the bridge, it is impossible to build construction supports at the designed bridge position. In this case, the bridge construction method can be adopted to avoid the terrain and terrain that affect the construction. Features. Planar out-of-position construction of bridges usually includes translation, translation and jacking construction. For simply-supported bridges commonly used in engineering, the stress state of the bridge in the jacking construction stage is quite different from that in the design and operation stage, and this method is applicable to limited bridge types. The translational construction occupies a large area of ​​the site, the slidin...

AI Technical Summary

Problems solved by technology

The translational construction occupies a large area of ​​the site, the sliding distance of the bridge is long, and the amount of temporary structures is large
