Problems solved by technology

According to the normal construction procedure, it should be installed from bottom to top, but at present, the owner gives the construction party a very short period of time, and the construction period is very tight. The existing installation method can no longer meet the urgent construction period requirements.

Embodiment Construction

[0012] The invention provides a method for installing a vertical section of a high-altitude large-diameter pipeline, which includes:

[0013] Step one, support platform construction; weld the support pipe support on the structural steel beam of the pipeline support platform, the support is made of channel steel [16 for diagonal bracing, and the platform uses 500mm*500mm*10mm steel plate; at the same time, the pipe is welded and supported The pipe support platform is used as the pipe support point, and the pipe support platform adopts the pipe wall stiffener as the support platform; each group of pipes is welded to no less than three groups of platforms.

[0014] Step 2: Use a car crane to hoist the vertical section of the pipeline, and release the car crane hook after the pipeline is installed. After the 200t crane station is in place, lift the vertical section of the pipeline, weld the pipeline after the pipeline is aligned at +49.8m, weld the pipeline after the alignment, and the...

Abstract

The invention relates to a pipeline installation method, and particularly relates to a method for installing a vertical section of an overhead pipeline. A method for installing a vertical section of an overhead large-diameter pipeline comprises the following steps of: 1, building a supporting platform; and 2, hoisting a pipeline of the vertical section by using a truck, and loosening a lifting hook of a truck-mounted crane after the pipeline is completely installed. The method disclosed by the invention can be used for accelerating the construction period of overhead pipeline installation, and meets the requirements of owners on the construction period.

Description

Technical field [0001] The invention relates to a pipeline installation method, in particular to an installation method of a vertical section of a high-altitude pipeline. Background technique [0002] With the rapid development of the iron and steel industry, the traditional industrial structure of various iron and steel plants can no longer meet market demand. More and more iron and steel industries are restructuring, technological transformation, expansion and other project transformations of their own structure. Among them, the interface method of new and old pipelines with large diameter at high altitude has become the most difficult point of the renovation project. In the project of extra-thick slab continuous caster, when the new and old pipes of the primary dust removal pipe are installed in the interface: the vertical pipe (φ2620) pipe center elevation of a dust removal pipe transformation is from +7.5m--+49.8m, and the single pipe weighs 32.7t . According to the normal...
