Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be construed that the scope of the above-mentioned subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0047]This embodiment provides a jacking construction method for a steel truss bridge. The steel truss bridge is constructed by segmental assembly, and the construction method for a row truss bridge provided in this embodiment can avoid steel truss bridges as much as possible. There is a large height difference between sections.

[0048] This embodiment specifically includes the following steps:

[0049] S1, build a jacking platform; such as figure 1 As shown, multiple jacking platforms are built at intervals along the design vertical curve 1 at the bottom of the main trus...

Abstract

The invention belongs to the technical field of bridge construction, and particularly relates to an incremental launching construction method of a steel truss bridge. The steel truss bridge is mounted in a manner of erecting a curve pushing platform and assembling the curve pushing in sections, and the method comprises the following steps: S1, constructing the pushing platform; s2, a pushing system is installed; s3, steel truss bridge segments are assembled and pushed, the steel truss bridge segments are assembled on the pushing platform, and the steel truss bridge segments are pushed to the next adjacent pushing system through the pushing system on the pushing platform; and S4, the steel truss bridge is assembled, and the next steel truss bridge section continues to be assembled and pushed until the steel truss bridge is assembled. By means of the construction method, the problem that large height difference exists between the steel truss bridge segments can be avoided as much as possible.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and particularly relates to a jacking construction method of a steel truss bridge. Background technique [0002] The bridge type of the double-layer steel truss bridge is mainly used for the viaduct design that spans rivers or other obstacles and does not affect the ground traffic. The double-layer steel truss bridge generally adopts the jacking construction technology when the space is limited. [0003] The jack-up construction is a relatively mature installation method. The specific method is to level the site on one side of the bridge, arrange a jack-up assembly platform, and the top surface of the platform is designed to be horizontal. On the assembly platform, the jack-up is assembled and pushed in sections until the whole bridge is reached. When it is in place, the beam will be dropped after the jacking is in place to realize the system conversion. [0004] This method is gener...
