BIM技术在市政大型污水输送管线设计中的应用

Application of BIM Technology in Municipal Large-Scale Wastewater Transmission Pipeline

大型污水管线是城市排水体系的重要组成部分,在市政道路下管线错综复杂的情况下利用建筑信息模型(BIM)技术对复杂的地下管线进行了三维建模,将二维图纸内容合并于一个模型中,直观展现地下管线的相互关系,有利于设计、施工相互交流、沟通,确保交底顺利进行。文章以南干线改造工程为例,通过模型构建、参数化、协同设计、碰撞交叉检查等方法对大型污水管线与BIM结合应用进行了研究,采用模型化的分析手段,有效提高市政给排水管线设计工作过程模块化工作的容错率,进一步提高工程效率。

Large-scale wastewater pipelines are an important part of the urban drainage system.In the case of complicated pipelines under municipal roads,BIM technology is used to carry out three-dimensional modeling of complex underground pipelines,and the content of two-dimensional drawings is combined into one model to intuitively display underground pipelines.The mutual relationship is conducive to the mutual communication and communication between design and construction,and ensures the smooth progress of disclosure.Taking the reconstruction project of the south trunk line as an example,this paper studies the combined application of large-scale sewage pipelines and BIM through model construction,parameterization,collaborative design,collision cross-checking,etc.,and uses model-based analysis methods to effectively improve the design of municipal water supply and drainage pipelines.The fault tolerance rate of the modular work of the working process further improves the engineering efficiency.
