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...

Examples

Embodiment 1

[0029] In the embodiment of the present invention: a method for transforming medium pipelines that hinders the installation of steel columns in expanded workshops is provided, and the construction steps are as follows:

[0030] Step 1: Find the obstruction points for the installation of steel columns for plant expansion, including:

[0031] 1. According to the longitudinal and transverse central axes of the steel columns 5 of the original factory building, and according to the design documents of the factory building expansion, extend and mark the longitudinal and transverse central axis positions of the steel columns 5 of the expanded factory building;

[0032] 2. Based on the marked intersection of the longitudinal and transverse central axes of the steel column 5 of the expanded factory building as the center, and according to the external dimensions of the steel column 5 of the expanded factory building, mark the contour line of the steel column 5 of the expanded factory bu...

Embodiment 2

[0044] Taking the expansion project of a 120t steel-making converter plant in Shandong, a medium pipeline transformation method proposed by the present invention that hinders the installation of steel columns in the expanded plant was used to complete the plant expansion work: project overview, the total elevation of the H-column steel columns of the expanded plant is 34.900m , the length of the steel column lattice structure is 18.400m, and there is one column at 300mm to the right of the center of the H column and 2 sticks medium pipeline, and the highest The central elevation of the medium pipeline is 19.200m.

[0045] The construction steps are:

[0046] Such as figure 1 As shown, Step 1: Find the obstruction point of the steel column installation of the plant extension:

[0047] 1. According to the longitudinal and transverse central axes of the steel columns 5 of the original factory building, and according to the design documents of the factory building expansion...
