Abstract

The invention provides a secondary rotation construction method for a horizontal rotation bridge. Primary rotation construction is added before a single rotation technology, on the basis of the original design beam body position, the two rotation angles are determined, then, on the basis of the original design construction map, pile foundation, bearing platform, rotation ball hinge installation and tower body / pier body construction are performed, and it is ensured that the tower body is parallel or approximately parallel to an existing structure; on the basis of the press angle, first-time rotation is performed, and it is ensured that the tower body obtained after one rotation construction is approximately perpendicular to the existing structure in position; then, the beam body is constructed or top pushing is performed on the beam; second-time rotation construction is performed, and the it is ensured that the tower body / pier body and the beam body are rotated at the same time to crossover the existing structure to the design position; finally, folding is performed to obtain the bridge. According to the secondary rotation construction method, the traditional single rotation technology is optimized and improved, the distance between the existing structure and the tower / pier body can be greatly increased during construction, the safety risk is lowered, the construction limit islowered, and therefore the construction efficiency is improved, and the whole project progress is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a secondary swivel construction method of a horizontal swivel bridge. Background technique [0002] A bridge is a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas for the passage of vehicles and pedestrians. With the continuous development of the construction industry and bridge construction technology, more and more swivel bridges are used in traffic construction in the industry. As a traffic facility across roads, railways and other important structures, the horizontal swivel construction technology has been obtained. breakthrough development. At present, the common method of domestic horizontal swivel bridges is to span the existing structure with a single horizontal swivel, such as synchronous single swivel of the tower and girder. Big safety risk, construction restrictions are relatively larg...
