Long-span steel trusses girder multi-point pushing system and pushing technology thereof
The invention discloses a long-span steel trusses girder multi-point pushing system and a pushing technology thereof. The multi-point pushing system is formed by six sets of main pushing systems which are respectively on the bottoms of two steel trusses girders, and auxiliary traction mechanisms on the bottoms of steel trusses girder lower booms. The main pushing system is provided with two longitudinal main slideways. The longitudinal main slideways are supported on temporary support slideway beams. The system makes stressing of a steel trusses girder which is provided with two or more main trusses clear in pushing construction, and ensures pushing quality of the steel trusses girders.
