Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a beam jacking construction device. Background Technology

[0002] With the continuous development of bridge construction technology, the incremental launching method, as an important bridge construction method, is widely used in the construction of long-span bridges. The traditional incremental launching method involves assembling the bridge superstructure in sections on a construction platform, and then using jacking or towing equipment to provide thrust, overcoming the sliding friction between the beam and the track, and pushing forward section by section until the complete superstructure is poured, assembled, and jacked into place.

[0003] This method has advantages such as high construction efficiency and minimal environmental impact, but some technical challenges remain in practical applications. For example, existing beam jacking construction devices reduce contact friction during bridge jacking by using rollers, but the connection points of these devices must be fixed and cannot be adjusted according to actual construction needs, thus limiting their application. Furthermore, the side rollers of this device also have fixed positions, preventing flexible adjustments based on changes in the bridge structure, further restricting their effectiveness in actual construction.
