BIM (Building Information Modelling) technology based municipal pipeline factory prefabrication and installation method

Abstract

The present invention relates to pipeline prefabrication and installation technologies, in particular to a BIM (Building Information Modelling) technology based municipal pipeline factory prefabrication and installation method. The method comprises the following steps of step 1, three-dimensional modeling: performing municipal pipeline three-dimensional modeling in each specialty of buildings by using Revit MEP software; step 2, scheme optimization: performing comparative analysis on different schemes according to the established three-dimensional integrated pipeline model, and selecting an optimal arrangement scheme; step 3, collision detection: performing collision detection on the three-dimension model by using a pipeline model based collision detection algorithm, and outputting a final three-dimension model until a collision result is zero collision; step 4, preprocessing of prefabrication processing: performing numbering on all pipe sections in the three-dimensional model according to an assembly sequence, and outputting and printing a prefabrication processing diagram and a numbering result; and step 5, prefabrication processing: manufacturing pipeline preforms according to the prefabrication processing diagram and the numbering result. The method has the advantages that the precision of prefabrication processing can be improved, the field working efficiency can be improved, and the like.

[0002] At present, in urban infrastructure construction projects, especially in municipal engineering construction projects, pipeline engineering has the characteristics of many pipe diameters, complex materials, different wall thickness series, and large welding work volume. During the construction process, it is affected by materials. Influenced by many restrictive factors such as supply, equipment delivery and safety, climate conditions, and on-site operating surfaces, especially the large amount of welding in pipeline connections, the layout of pipelines in traditional engineering design methods is not accurate enough, resulting in a low degree of prefabrication. Most rely on on-site construction and installation methods. This method first requires a large number of operators on site, which brings a certain amount of pressure to the daily management of the site.

Secondly, the on-site environment is relatively complicated, the work interface is chaotic, and the work efficiency of workers is low

Furthermore, on-site processing must require a lot of fire points, which undoubtedly increases the safety hazards on site.
