The invention discloses a construction method of a large-span river-crossing steel truss bridge structure, which solves the problem that a large hoisting machine cannot be used for hoisting due to the limitation of working conditions, and saves the cost and shortens the construction period compared with the construction of a bridge erecting machine with high complexity. Moreover, the steel pipe piles form the water supporting platform to serve as a temporary support, required construction equipment is simple and high in applicability, the supporting platform can be constructed in advance, the construction period can be guaranteed, and the steel pipe piles can be repeatedly used and are good in economical efficiency. The problems that the construction period is long and the cost is high when a conventional construction method is adopted for large-span river-crossing steel truss bridge construction are solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a large-span cross-river steel truss bridge structure. Background technique [0002] For the construction of long-span cross-river steel truss bridge structures, large-scale hoisting machinery is usually used for overall hoisting or professional bridge erecting machine equipment is used for construction. Large-scale hoisting machinery is used for hoisting. Generally, after each truss section is assembled on site, large-scale hoisting machinery is used to hoist on the bank of the river or on the completed structure. This method requires a larger assembly site for components. The bearing capacity of the structure is high. If it stands on the completed structure, the structure needs to be checked and reinforced. The use of bridge erecting machine equipment for construction requires the use of special bridge erecting machine equipment. The inst...
