Abstract

The invention belongs to the technical field of steel structure bridge construction, and discloses a double-layer steel box girder bridge installation method and a combined support for installation. The combined support for installation of the double-layer steel box girder bridge comprises a first stand column set, a first cross beam, a second stand column set, a second cross beam and a base plate. The first stand column set comprises a plurality of first stand columns, and the first cross beam is fixed to the first stand columns to form a lower-layer support. The second upright post group comprises a plurality of second upright posts, and the second cross beam is fixed on the plurality of second upright posts to form an upper-layer bracket. The first stand columns and the second stand columns are all fixed to the base plate. The height of the first stand column is smaller than that of the second stand column. According to the double-layer steel box girder bridge installation method and the combined support for installation, efficient and synchronous installation of double-layer steel box girder bridge installation can be achieved.

Description

technical field [0001] The invention relates to the technical field of steel structure bridge construction, in particular to a double-layer steel box girder bridge installation method and a combined bracket for installation. Background technique [0002] Double-layer bridges can significantly improve urban traffic capacity and reduce land occupation, so they are widely used in municipal viaducts. Usually, the design width of a single bridge is generally 12 to 16 meters, with 3 to 4 lanes. Due to the influence of the complex environment of the municipal viaduct, most of them are installed by the bracket method, and each layer of construction is to build a layer of brackets; Large, requires a large amount of support materials, covers a large area, and requires framed construction, high cost and long cycle. At the same time, due to the limited operating space, construction machinery cannot be used, etc., resulting in complex construction process, long period, high cost, and hi...
