Abstract

The invention discloses a plane swivel construction method of a cable-stayed bridge. A main beam of the cable-stayed bridge is a reinforced concrete beam and is composed of two side span beam sectionsand a middle span bean section connected between the two side span beam sections. When performing plane swivel construction of the cable-stayed bridge, the plane swivel construction method includes the steps of 1, construction of swivel systems; 2, construction of a supporting structure of the lower portion of the bridge; 3, construction of forming of beam bodies; 4, construction of cable bent towers and installation of stay cables; 5, the plane swivel construction; 6, side span closure construction; and 7, mid-span closure construction. The plane swivel construction method of the cable-stayed bridge is simple in steps, reasonable in design, simple in construction and good in use effect. By combining two times of counterweight construction and lateral lifting of a swivel structure beforeswivel, the problem that the swivel structure spans auxiliary supporting piers can be effectively solved, the construction process of bridge swivel and closure is simply and quickly completed, the construction process is safe, the construction period is short, and the construction cost is low.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a plane swivel construction method of a cable-stayed bridge. Background technique [0002] In recent years, during the construction of overspan railway bridges, in order to ensure the traffic safety of railway business lines, try to avoid setting up support construction on the road, the bridge swivel construction technology has been gradually promoted and applied, so that the bridge construction process will not affect the train traffic. Swivel construction is to build the main structure on one or both sides of the existing traffic line, and then use the rotation system to turn the main structure to the bridge design line position. Monitoring and control are required during the rotation process. According to the different rotation directions, the swivel method can be divided into vertical rotation method, horizontal rotation method and horizontal and verti...
