Erection construction method for single-line box beams and double-line box beam of elevated station

Abstract

The invention discloses an erection construction method for single-line box beams and a double-line box beam of an elevated station. The erection construction method comprises the steps that one, a bridge erection machine for erecting the double-line box beam hoists two sleeper beams onto padstones; two, beam moving devices are hoisted onto linear rails and located between the sleeper beams; three, the bridge erection machine for erecting the double-line box beam erects one single-line box beam onto the two beam moving devices; four, the two beam moving devices transfer the single-line box beam to a beam falling position and jack the single-line box beam; five, the beam moving devices are moved back between the sleeper beams and downwards put the single-line box beam onto the two sleeper beams; six, after the single-line box beam is replaced with the other single-line box beam, the steps from step three to step five are repeated; seven, the two single-line box beams are jacked, and the bridge erection machine for erecting the double-line box beam hoists the sleeper beams and the beam moving devices onto the ground; eight, the two single-line box beams are downwards put onto the padstones; and nine, the double-line box beam is erected. By adoption of the erection construction method, construction of the single-line box beams and the double-line box beam is completed through one set of equipment.

Description

technical field [0001] The invention relates to the field of high-speed railway bridge construction. More specifically, the present invention relates to a method for erecting single and double track box girders of an elevated station. Background technique [0002] The 62-hole single-line box girder of Shanghai Changshu elevated station is arranged on both sides of the main line double-line box girder. For the special working conditions of the Shu elevated station, if two sets of equipment are constructed at the same time, the two sets of equipment will affect each other in space, and for the 62-hole single-track box girder, it is necessary to allocate a set of girder erection equipment and supporting personnel, which is costly. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for single- and double-line box girder erection of elevated stations, so as to solve the technical problems of erecting single- and double-l...
