Bridge pier column deflection correction device

Abstract

The invention relates to the technical field of bridge construction, in particular to a bridge and pier column deviation rectifying device. The bridge and pier column deviation rectifying device comprises a right-angle support, a sliding base, a first jack and a second jack. The first jack is placed upwards between a bridge and a pier column in the vertical direction and anchored to the top end of the pier column. The right-angle support comprises a parallel guide rail and a mounting base, wherein the parallel guide rail is arranged horizontally in the moving direction of the pier column, and the mounting base extends vertically downwards along one end of the parallel guide rail. The parallel guide rail is fixed to the bottom face of the bridge, and the mounting base is located on the back side face of the pier column in the moving direction of the pier column. The second jack is mounted on the mounting base in the horizontal direction and faces the pier column. The sliding base is located over the first jack and arranged on the horizontal guide rail and can move along the horizontal guide rail. The bottom of the sliding base is provided with a clamping hole matched with the first jack. The first jack is inserted in the clamping hole when conducting upward jacking so that the bridge can be jacked through the sliding base. The bridge and pier column deviation rectifying device can accurately rectify deviation of the pier column.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a deviation correcting device for bridge pier columns. Background technique [0002] Due to the high height and small section of the bridge pier column, its transverse stiffness is relatively small. Due to poor design and construction or the accumulation of dynamic loads on the bridge throughout the year, it is easy to cause the deflection of the pier column. If it is not timely Correction, the pier column will continue to deflect, so that the concrete at the root of the deflection will gradually become a tension zone, and the tensile strength of the concrete is very poor, and the circumferential cracks will gradually appear on the concrete surface, and continue to develop, eventually making the pier The column is completely destroyed. Therefore, it is necessary to correct the deflection of the pier column in time, and the existing method of correcting and resetting ...

[0002] Due to the high height and small section of the bridge pier column, its transverse stiffness is relatively small. Due to poor design and construction or the accumulation of dynamic loads on the bridge throughout the year, it is easy to cause the deflection of the pier column. If it is not timely Correction, the pier column will continue to deflect, so that the concrete at the root of the deflection will gradually become a tension zone, and the tensile strength of the concrete is very poor, and the circumferential cracks will gradually appear on the concrete surface, and continue to develop, eventually making the pier The column is completely destroyed

Therefore, it is necessary to correct the deflection of the pier column in time, and the existing method of correcting and resetting the pier column is to use a jack to act on the bridge or the pier column, so that the pier column can overcome the friction between the bridge and the bridge and reset it longitudinally. Due to the huge friction force between the bridge and the pier column, the jack needs to provide a huge jacking force, which makes the reset difficult, and it is difficult to ensure accurate control of the displacement of the pier column during the jacking process
