Simulation of intelligent three-dimensional segmented layout method for urban underground pipelines
Generally,the urban underground environment is complex and diverse,with various geological condi-tions,underground facilities,and underground pipelines,making pipeline layout difficult.Therefore,this paper presen-ted a method of segmented layout for urban underground pipelines based on BIM.Firstly,we used the coordinates and attribute information in three-dimensional space to calculate the spatial relationship between underground areas,thus obtaining a safe distance for the segmented layout of underground pipelines.Secondly,we built a model of urban un-derground pipelines by using BIM.After converting local coordinates,we got a triangular irregular network representa-tion of the pipeline surface.Moreover,we imported the network information of underground pipelines into BIM soft-ware,and then constructed a 3D model.Finally,we achieved the segmented layout of urban underground pipelines through spatial positioning,shape modeling,attribute setting,and correlation establishment.Meanwhile,we displayed the visualization results of the layout through the BIM model.Experiment results prove that the proposed method is ef-fective in the segmented layout of urban underground pipelines,with reasonable route planning and convenient man-agement and maintenance in the later stage.
