A modification method for obstructing the installation of medium pipes in steel columns of expanded factory buildings

Abstract

The invention discloses a transformation method for blocking of an expanded plant steel column installing a medium pipeline, and belongs to the technical field of pipeline transformation. According tothe longitudinal axis of a medium pipeline and the transverse dimension of the blocking part of the expanded plant steel column longitudinal contour line, a pipeline bracket at the blocking part of the medium pipeline is structurally transformed, then the medium pipeline at the blocking part is translated to the right side of the longitudinal position of the expanded plant steel column to make the space needed to install the expanded plant steel column, and thus the problem of the installation space of the expanded plant steel column and the medium pipeline at the blocking part is solved.

Description

technical field [0001] The invention belongs to the technical field of pipeline reconstruction, and in particular relates to a reconstruction method for medium pipelines that hinder the installation of steel columns in expanded factory buildings. Background technique [0002] Metallurgical engineering often encounters the work of expanding the original plant due to the process transformation of the subsequent production line or the increase of the production scale. When most factories are expanded, the original production lines in the workshop are generally not scheduled to stop production, and the pipe network in the workshop cannot stop supplying energy media due to production. However, some parts of the steel columns of the expanded factory building will encounter the problem that the medium pipe outside the factory building blocks the installation of the steel column, and it may happen that the steel column of the expanded factory building is not a lattice steel column o...

Problems solved by technology

When most factories are expanded, the original production lines in the workshop are generally not scheduled to stop production, and the pipe network in the workshop cannot stop supplying energy media due to production.

However, some parts of the steel columns of the expanded factory building will encounter the problem that the medium pipe outside the factory building blocks the installation of the steel column, and it may happen that the steel column of the expanded factory building is not a lattice steel column or the installation elevation of the medium pipeline has exceeded the elevation of the lattice part of the steel column. It is impossible to adopt the internal support of the steel column lattice that will be blocked by the medium pipeline

In addition, the original pipe and steel column welding form is changed to the bolt fastening connection form, and then the internal support of the bolt-fastened steel column column is removed in advance to allow the construction space for the steel column installation of the expanded factory building to pass through the medium pipeline. , resulting in that the steel columns of the expanded plant cannot be directly installed in place

If the obstruction problem between the steel columns of the expanded plant and the external medium pipes cannot be solved in time, it will affect the installation of the steel columns of the expanded plant and directly restrict the construction progress of the project
