地下管线BIM模型快速构建及教学应用

Rapid construction and teaching application of underground pipeline BIM model

在职业技术技能教学中,城市地下管线测绘一直是教学的难点。地下管线位于地面以下,在地表往往只能看到窨井盖等管线附属设施,在实际的地下管线测绘技能教学过程中无法完全展现地下管线的真实形态,不利于学生知识技能的掌握。基于城市地下市政基础设施普查数据库,二次开发Revit软件插件,快速构建地下管线及附属设施的三维BIM模型,进行虚拟仿真教学,对学生了解地下管线形态、掌握地下管线测绘方法有重要作用,有助于提高课堂效率,增强学生技能水平。

Urban underground pipeline surveying has always been a difficult point in vocational and technical skills teaching.Underground pipelines are located below the ground,and often only auxiliary facilities such as manhole covers can be seen on the surface.In the actual teaching process of underground pipeline surveying and mapping skills,the true form of underground pipelines cannot be fully displayed,which is not conducive to the mastery of knowledge and skills by students.Based on the urban underground municipal infrastructure survey database,develop Revit software plugins to quickly construct three-dimensional BIM models of underground pipelines and ancillary facilities,conduct virtual simulation teaching,and play an important role in helping students understand the shape of underground pipelines and master underground pipeline surveying methods,improve classroom efficiency,and enhance their skill levels.
