Abstract

The invention relates to a counter-force support structure for longitudinal dragging construction of a steel beam and a using method of the counter-force support structure, and relates to the technical field of bridge dragging construction. The counter-force support structure comprises a foundation platform; steel pipe brackets which are arranged on the top surface of the foundation platform in pairs; a slideway beam which is arranged on the top surface of the steel pipe bracket; a dragging system which is arranged on one side of the top surface of the slideway beam and is used for dragging the to-be-replaced steel beam on the top surface of the slideway beam; wherein the foundation platform is of a driven type steel pipe pile foundation structure; the steel pipe support comprises a vertical stand column structure and an inclined stand column structure. The steel pipe pile foundation and the bearing platform are combined into a whole, a traditional cast-in-situ bored pile foundation isreplaced, and the advantages of being simple in construction process and clear in force transmission path are achieved.

Description

technical field [0001] The application relates to the technical field of bridge dragging construction, in particular to a reaction force support structure for longitudinal dragging construction of steel girders and a method for using the same. Background technique [0002] Railway bridges on existing lines, especially bridges with a long service life, usually adopt military truss structures that require less equipment due to the limitations of backward bridge construction technology and equipment. [0003] The steel truss girder railway bridge with military truss structure often has the problems of insufficient lateral stiffness of the main truss, excessive lateral vibration amplitude and insufficient bearing capacity when trains pass. In addition, due to the overload operation, there are still defects such as cracks in the upper cross-connection, broken high-strength bolts, and dead deflection of the main truss. [0004] In order to meet the requirements of modern railway ...
