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 suppo

Embodiment Construction

[0018] The invention discloses a steel box girder jacking and sliding construction method, including the following steps: 1), truncation mark identification; 2), reference segment installation; 3), pre-correction before the segment is in place; 4), Margin cutting; 5), segment fine adjustment; 6), beam bottom pad copying; 7), installation of beam drop auxiliary device; 8), drop beam positioning; 9), drop beam into a bridge.

[0019] The above steps are specifically expanded as follows:

[0020] The step 1) is specifically: after the steel box girder is assembled on the assembly platform, measure the camber, transverse slope, and external dimensions and report for inspection. Mark the punching points at both ends of the axis, and make clear marks with paint, as the reference point for measuring the position of the segmental beam.

[0021] The step 2) is specifically: starting from the 35# small pile end at the south end of the bridge, install the 35-37# span inner steel box gir...

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...
