A transformation method for media pipelines that hinder the installation of steel columns in expanded workshops

Abstract

The invention discloses a method for transforming a medium pipeline blocking mounting of a steel column of an extended factory. Based on the longitudinal axis of the medium pipeline and the transversesize of the blocking portion of the longitudinal shape contour line of the steel column of the extended factory, a pipeline support at the blocking position of the medium pipeline is structurally transformed, the portion, at the blocking position, of the medium pipeline is horizontally moved to the right side of the longitudinal position of the steel column of the extended factory, a 200 mm transverse distance is formed between the outer surface of the left side of the transformed medium pipeline and the longitudinal outer contour line on the right side of the steel column of the extended factory, and space needed by mounting of the steel column of the extended factory is vacated. The method includes the sequential construction steps that blocking points of mounting of the steel column ofthe extended factory are searched for, a medium pipeline support at the blocking position of factory extension is transformed, and the portion, at the blocking position, of the medium pipeline is transformed. The problem about mounting of the steel column of the extended factory at the blocking position of the medium pipeline is solved, the risk of supply interruption of an energy medium caused by blocking of the medium pipeline on mounting of the steel column of factory extension is reduced, and it is guaranteed that engineering construction and workshop production are effectively carried out.

Description

technical field [0001] The invention relates to the technical field of transformation of medium pipelines, in particular to a transformation method for medium pipelines that hinder the installation of steel columns in expanded workshops. 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, and some steel columns in the expanded factory will encounter the problem that the medium pipes outside the factory block the installation of steel columns. And it may happen that the steel columns of the expanded factory building are not lattice steel columns or the installation elevation of the medium pipe...

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, and some steel columns in the expanded factory will encounter the problem that the medium pipes outside the factory block the installation of steel columns. And it may happen that the steel columns of the expanded factory building are not lattice steel columns or the installation elevation of the medium pipeline has exceeded the elevation of the steel column lattice part, and it is impossible to adopt the internal support of the steel column lattice structure that will block the medium pipeline. The fixed form of welding with the steel column is changed to the form of bolt fastening connection, and then by removing the inner support of the steel column fastened by the bolt in advance, the construction space required for the steel column installation of the expanded plant to pass through the medium pipeline is released, resulting in the steel column of the expanded plant The column cannot be directly installed in place. If the obstruction problem between the steel column of the expanded plant and the external medium pipeline cannot be resolved in time, it will affect the installation of the steel column of the subsequent expanded plant and directly restrict the construction progress of the project.
