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.
