Abstract

The invention relates to the technical field of T-shaped beam bridge beam-erecting methods, and provides a bridging method for a T-shaped beam bridge. The bridging method comprises the steps that during hole passing, a front guiding pillar and a rear guiding pillar of a bridge erecting machine shrink, and two beam-hoisting trolleys on a main beam are supported on an erected beam bridge deck; the main beam is driven to move forward, so that the front guiding pillar and the rear guiding pillar are moved to the position above two piers at the beam-erecting position correspondingly, and the frontguiding pillar and the rear guiding pillar are stretched downward and supported on the two piers at the beam-erecting position; and during beam erecting, the two beam-hoisting trolleys are matched with a beam transporting trolley for conducting beam feeding, and after a new beam to be erected is transported to the position above the beam-erecting position, the new beam to be erected is erected onthe piers. According to the bridging method for the T-shaped beam bridge, overall hole passing of equipment can be completed only through mutual cooperation of three supporting legs, operation is simple, the hole passing time of the equipment is greatly reduced; and in addition, through the lifting front guiding pillar and the rear guiding pillar, overall lifting of the equipment can be achieved,so that the beam-changing process is not affected by natural conditions such as wind force, and errors do not occur during beam falling.

Description

technical field [0001] The invention relates to the technical field of girder erecting methods for T-shaped girder bridges, in particular to a method for erecting T-shaped girder bridges. Background technique [0002] For the construction of simply-supported girder bridges on new railway lines, there are already many stereotyped bridge erecting machines. With the help of these equipment, the safe and efficient erection of whole-hole prefabricated beams can be realized, which greatly improves the construction speed of bridges. However, because the height of the existing bridge erecting machine can reach 8m during construction, which is seriously over the limit, therefore, under the existing line conditions, the existing bridge erecting machine is convenient for erecting new porous beams after the old beams are removed. If it is not applicable, a new bridging method needs to be proposed. Contents of the invention [0003] The purpose of the present invention is to propose a...
