From the experience of the development and implementation of temporary railway transfer overpasses in reconstruction of the blast furnace complex facilities
The article is devoted to the analysis of the author’s experience in reconstruction of the blast furnace complex in the functioning manufacture conditions. The scheme of a real construction site with indication the location of main elements is shown. Principles of organizing of construction site and construction process management are discussed in the text. A technological solutions proposed by the authors regarding the process of pre-assembly, installation and sliding of a blast furnace, namely : using of temporary railway overpasses for transmission of structural units from the place of enlargement to the construction site; structure, location and working principle of a temporary stand for enlargement of a blast furnace; the list and purpose of used construction cranes are also outlined and detailed in the article. Moreover, an issues related to the reconstruction of auxiliary facilities, for example a dust collector, are covered in this article. A description of the directly process of sliding the furnace into the design position and conclusions made about the appropriateness of applying the selected technological solutions are described at the end of the article.
