Problems solved by technology

[0003] However, there are the following disadvantages: the controlled high-voltage lines on both sides of the bridge affect the working space of the hoisting machinery and equipment; It is especially not suitable for steel box girder installation under complex working conditions such as the maximum clearance height of the underpass of the expressway on the west side of the bridge site, such as the maximum clearance height of less than 4.5m.

Abstract

The invention relates to a longitudinal and transverse sliding construction process of a steel box girder. With the cooperation of a pier column and a support, the installation of the steel box girderunder complex geological conditions is completed through horizontal, longitudinal and horizontal rolling and sliding of segment blocks. The longitudinal and transverse sliding construction process ofthe steel box girder has the advantages of improving safety production, being free of influences on the working space, achieving installation of the steel box girder in complicated working conditionswhere the maximum clearance height of underneath pass channels of expressways is less than 4.5 meters and the like.

Description

technical field [0001] The invention relates to the technical field of steel box girders, in particular to a longitudinal and lateral sliding construction technology of steel box girders. Background technique [0002] At present, steel box girder, also known as steel plate box girder, is a commonly used structural form of long-span bridges. Generally used on bridges with large spans, it is called steel box girder because it looks like a box. In the steel box girder installation project of municipal or traffic engineering bridges, the method of longitudinal sliding after horizontal segmentation is generally adopted. In long-span cable-supported bridges, the steel box girder spans hundreds of meters to thousands of meters, and is generally divided into several beam sections for manufacture and installation. Its cross section has wide and flat shape characteristics, and its aspect ratio reaches 1 : Around 10. [0003] However, there are the following disadvantages: the contr...
