Abstract

The invention relates to bridge construction technology, in particular to a horizontal swivel structure and a construction method of a super-large tonnage asymmetric composite girder cable-stayed bridge. It includes concrete foundation piles, caps, turntables and swivel slide rails. The caps are divided into upper caps and lower caps. The swivel slides are divided into legs and slideways. For supporting feet, the lower bearing platform is provided with a lower turntable, a positioning pin shaft and a slideway, the upper turntable is connected with the lower turntable through a positioning pin shaft, the upper turntable is bonded to the lower turntable, and the braces are fitted to the slideway. The present invention has significant effects on solving the problems of complex horizontal swivel construction process and high construction cost of large-tonnage, asymmetric mixed-girder cable-stayed bridges, and also has many advantages such as simple construction procedures, fast construction speed, safety and reliability, and low engineering cost. advantage.

Description

technical field [0001] The invention relates to bridge construction technology, in particular to a horizontal swivel structure and a construction method of a super-large-tonnage asymmetric composite girder cable-stayed bridge. Background technique [0002] A cable-stayed bridge is a structural system composed of towers under pressure, cables under tension and girders under bending. It has the characteristics of large spanning capacity, small girder height, and reasonable stress. Since the combination of steel and concrete can make full use of the properties of the material and improve the mechanical properties and improve the economy, hybrid girder cable-stayed bridges are increasingly favored by bridge builders. [0003] Hybrid girder cable-stayed bridge means that the main girder of the cable-stayed bridge is composed of two different materials along the length direction of the girder. . The hybrid girder cable-stayed bridge has a larger spanning capacity because its mai...
