[0002] In recent years, the walking jacking construction technology has developed rapidly. Due to its advantage of being able to cross unfavorable geographical conditions, it is being widely used in bridge construction. The jacking construction technology has the advantages of small impact on traffic and the environment, the ability to cross unfavorable locations and important urban traffic roads and assembly areas, and high adjustability. With the continuous development of the walking jacking construction technology, the walking jacking construction of large-span steel beams has gradually become popular and is highly praised by various construction units.

[0003] However, the traditional jacking construction technology cannot meet people's needs, and it has the following defects: First, the original steel beam jacking construction adopts a welded H-shaped steel guide beam with the same height as the steel beam cross-section. During the use process, large steel plates are cut and welded into a whole, which increases the use of steel and cannot solve the problem that when the steel beam cross-section is high, the lateral wind load of the guide beam is large and the stability is poor; Second, there is no assembly structure designed, and a large-tonnage crane is used for installation and disassembly, which has high transportation costs and is difficult, seriously affecting the construction efficiency. The steel used cannot be recycled, resulting in a waste of resources. Utility Model Content
