Problems solved by technology

[0003] Among the bridges studied by the present invention, the Hutong Bridge includes a main channel bridge, a special channel bridge, a simply supported steel truss bridge and land approach bridges on both banks, with a total length of 11.072km. For the lower railway layer, if the traditional assembly process is used, it is cumbersome, and it is difficult to ensure the positioning accuracy during on-site assembly. Therefore, if the traditional assembly process is used, it is far from meeting the requirements of the project cycle, and the workpiece needs to be h

Abstract

The invention relates to a full-welding truss section modularized splicing method. According to the method, each assembly of each truss section is divided into multiple modules, and each module is independently spliced. The method includes firstly, a truss sheet module splicing method, secondly, a transverse connecting sheet module splicing method, thirdly, an upper-layer road bridge face module splicing method, fourthly, a lower-layer railway bridge face module splicing method, fifthly, a road combination section longitudinal and transverse beam splicing method and sixthly, a truss whole section module splicing method. A bridge is spliced in a modularized manner, part of the modules of the bridge can be spliced on a bridge production site, the difficulty of constructing the bridge on the site is lowered, the labor amount for manufacturing the bridge is reduced, the manufacturing time of the bridge is shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a modular assembly method for all-welded truss segments, which belongs to the technical field of bridge manufacturing. Background technique [0002] With the rapid development of social economy, the pressure of land transportation is becoming more and more prominent. In order to solve this pressure, it is imperative to build a large number of railways, expressways and other projects. The use of bridges is becoming inevitable, and people are also designing the structures of bridges with different distances. [0003] Among the bridges studied by the present invention, the Hutong Bridge includes a main channel bridge, a special channel bridge, a simply supported steel truss bridge and land approach bridges on both banks, with a total length of 11.072km. For the lower railway layer, if the traditional assembly process is used, it is cumbersome, and it is difficult to ensure the positioning accuracy during on-site assembly. Therefo...
