The bridge swivel device for traffic construction and bridge construction provided by the present invention has the advantages of simple operation, less uneven stress, and avoiding jamming and the like.

Description

technical field [0001] The invention relates to the technical field of bridge swivels, in particular to a bridge swivel device for bridge construction in traffic construction. Background technique [0002] Bridge swivel construction is a bridging technology developed after the 1940s. It is on both sides of the river or at an appropriate position. The half bridge is prefabricated first by using the terrain and simple brackets, and then the bridge structure itself is used as the rotating body, and some equipment is used to rotate the two half bridges to the axis of the bridge position. The location is closed to form a bridge, and its characteristics are: the terrain can be used, which is convenient for prefabrication; the construction does not affect the traffic; the construction equipment is small, the installation is simple; the construction materials are saved. The construction process is simple and the construction is fast; it is suitable for single-span and three-span br...
