The invention discloses an assembled support device applied to steel box girder road-crossing bridge installation and a construction method, and belongs to the technical field of bridge steel box girder installation construction. The device comprises a first support, an adjusting pier and a second support, and the first support can be fixed to the ground and form a bearing face; the adjusting pier can change the extension length of the top end and the bottom end of the adjusting pier in the vertical direction, and the bottom end of the adjusting pier is fixedly connected to the bearing surface; the second support is in separable transmission connection with the top end of the adjusting pier, and the bottom end of the second support is provided with a supporting roller. According to the device, an existing bridge body is punched, so that the second support for mounting construction of an over-crossing existing bridge body structure can penetrate through the bridge body through the adjusting pier, the ground below the bridge body serves as a supporting foundation by means of the first support, and the mounting precision of a steel box girder and the safety of the bridge body are guaranteed; the second support and the adjusting pier can be rapidly assembled and disassembled, the second support can conveniently complete transverse moving and unloading based on the bridge body structure, the turnover rate is high, and the influence on the existing bridge body is further reduced.
Description
technical field [0001] The invention relates to the technical field of installation and construction of bridge steel box girders, in particular to an assembled support device and a construction method applied to the installation of steel box girder cross-road bridges. Background technique [0002] At present, the mainstream construction methods for the installation of steel box girders include the bracket method and the jacking method. Among them, the bracket method is more suitable for the construction conditions of flat bridge site and short pier body, and has strong applicability to the longitudinal slope and flat curve of the steel box girder; while the jacking method has lower requirements for the installation environment, but The applicability is poor for variable-section steel box girders or bridge longitudinal slopes and flat curve radius changes. At the same time, when the steel box girder has a large single-span span on the pier, it is also necessary to combine the...
