Abstract

The invention discloses a deviation-correcting and repairing method for a bridge cast steel single roller support. The deviation-correcting and repairing method comprises the following steps that S1,general inspection of the inclination angle of a cast steel single roller of the cast steel single roller support is carried out; S2, a superstructure of a bridge is synchronously jacked by multiple self-locking jacks; S3, the constraint of a limiting toothed plate and a limiting stiffening plate on the cast steel single roller support to be corrected and repaired is eliminated; S4, the horizontaldistance of an upper notch and a lower notch in the longitudinal bridge direction is measured, that is, the support correcting displacement value delta; S5, the cast steel single roller support to becorrected and repaired is corrected according to the support correcting displacement value delta; S6, the superstructure of the bridge is lowered step-by-step; S7, the limiting toothed plate of the corrected and repaired cast steel single roller is welded; and S8, jacking load of the multiple self-locking jacks is synchronously reduced step-by-step, and the limiting stiffening plate is welded. The deviation-correcting and repairing method has the advantage of easy, convenient, safe and rapid correction, and can be widely applied to the technical field of bridge support correction.

Description

technical field [0001] The invention relates to the technical field of deviation correction of bridge supports. More specifically, the invention relates to a deflection correcting and repairing method for a bridge cast steel single roller bearing. Background technique [0002] The bridge bearing is one of the important components of the bridge, which plays the role of transmitting the reaction force and deformation of the upper structure to the lower structure. The cast steel bearing has a strong bearing capacity and can adapt to the needs of displacement and rotation of the bridge. In the 1960s, before rubber bearings such as rubber and PTFE plates appeared, cast steel bearings were widely used in road and railway bridges. Although cast steel bearings have a strong bearing capacity, they are large in size, consumable, high in rigidity, and force-transmitting rapidly, which can easily cause damage to the lower structure of the bridge, and is prone to corrosion and high mai...
