Steel box beam jacking pushing and slide moving construction method and beam falling auxiliary device

Abstract

The invention belongs to the field of bridge construction, and particularly relates to a steel box beam jacking pushing and slide moving construction method and a beam falling auxiliary device. The method comprises the following steps of (1) cutting mark marking; (2) reference section installation; (3) deviation pre-correction before section in-place; (4) margin cutting; (5) section fine adjustment; (6) beam bottom leveling padding; (7) beam falling auxiliary device installation; (8) beam falling positioning; (9) beam falling bridge forming. The method and the device provided by the invention have the beneficial effects that the construction is simple and convenient, the efficiency is high, the construction and the installation are accurate, and the like.

Description

technical field [0001] The invention belongs to the field of bridge construction, and in particular relates to a steel box girder jacking and sliding construction method and an auxiliary device for falling beams. Background technique [0002] The traffic form of viaducts and overpasses in modern society is an important means of dredging urban traffic jams. The construction and installation of beams between bridge piers is an important stage of bridge body construction. The construction method of adopting integrated falling beams between piers in the prior art has the following technical problems: 1) It is not conducive to adjust the alignment of the bridge when the beams are integrated between the piers; 2) If multiple joints are integrated and the beams are dropped at the same time, the number of pier supports involved will be large, and it is difficult to align multiple supports at the same time when the beams are dropped; 3) , The number of falling beam cylinders occupied...

Problems solved by technology

[0002] The traffic form of viaducts and overpasses in modern society is an important means of dredging traffic congestion in cities. The construction and installation of beams between bridge piers is an important stage of bridge body construction. The construction method of adopting integrated falling beams between piers in the prior art has the following technical problems: 1) It is not conducive to adjust the alignment of the bridge when the beams are integrated between the piers; 2) If multiple beams are integrated and dropped at the same time, the number of pier supports involved will be large, and it is difficult to align multiple supports at the same time when the beams are dropped; 3) , The number of falling beam cylinders occupied by the integrated falling beam is large; 4) The number of pads copied on the track beam at the same time for the integrated multi-section beam section is large, and there is butter in the slide beam, and the alignment of the front and rear segments is finely adjusted Contact collisions are unavoidable, especially in areas with large longitudinal slopes and Bailey beam areas, which are not easy to control
