Abstract

The invention provides a bridge turning device for traffic construction bridge construction. The bridge turning device for traffic construction bridge construction comprises a mounting platform, four positioning steel bars which are fixedly mounted at the top of the mounting platform and are distributed in a rectangular array, a positioning steel framework which is fixedly mounted on the four positioning steel bars, a spherical hinge lower disc which is fixedly mounted at the top of the positioning steel framework, and a lower spherical hinge which is fixedly mounted at the top of the spherical hinge lower disc. The bridge turning device for traffic construction bridge construction has the advantages that operation is easy, the phenomenon of uneven stress is reduced, and the phenomena of blocking and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of bridge swivels, in particular to a bridge swivel device for traffic construction and bridge construction. Background technique [0002] Bridge swivel construction is a bridge-building technology developed after the 1940s. It is on both banks of the river or at a suitable location. The half-bridge is prefabricated first using the terrain and the simple bracket, and then the bridge structure itself is used as the rotating body, and some machinery and equipment are 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 and the installation is simple; the construction materials are saved. The construction process is simple and the construction is rapid; it is suitable for single...
