Abstract

The invention discloses a mountainous area ultrahigh pass-keeping curve cast-in-place box girder combined support and an erecting method. The mountainous area ultrahigh pass-keeping curve cast-in-place box girder combined support comprises a stand column support assembly fixedly arranged on the side face of a pier column, and the stand column support assembly is perpendicular to the tangent line of a curve section between adjacent pier columns; a bailey beam is vertically and fixedly arranged at the upper end of the stand column support assembly, a distribution beam is fixedly arranged at theupper end of the bailey beam, and a bowl buckle support assembly is fixedly arranged at the upper end of the distribution beam. In the prior art, the distances between the stand column supports located on the adjacent pier columns are not equal in length, so that the lengths of the bailey beams installed on the stand column supports are different, and the bearing performance of the bailey beams cannot be completely utilized.

Description

technical field [0001] The application relates to the field of bridge construction, in particular to a composite bracket and erection method of a cast-in-place box girder with a super-high protection curve in a mountainous area. Background technique [0002] Cast-in-place beams are a common design form in bridge engineering, and are mostly used in the design of curved lines. Since the traditional buckle support is recommended to have a maximum erection distance of 24m according to the specification requirements, a new support design form must be adopted for the erection of cast-in-place box girder supports exceeding 24m in height, and according to the traffic requirements of the project, the normal passage of vehicles must be ensured at the support . Chinese patent, CN110593110A discloses a kind of box girder cast-in-place bracket suitable for curves and vertical and horizontal slopes and its construction method in CN110593110A, which is suitable for curves and vertical and...
