城市级地下管网BIM建设及应用

随着测绘地理信息技术和BIM技术在城市发展中的深入应用,城市级地下管网BIM建设成为智慧城市建设三维实景中国建设中的必要一环。本文结合新型基础测绘在地下空间测绘中的应用,提出利用地下管网测绘数据与BIM深度融合技术快速构建城市级地下管网BIM的技术流程和体系,构建了城市级别(GIS)场景下的精细化BIM模型,实现了测绘数据与设计数据的无缝融合,打通了多专业协同中与测绘数据融合的通道,为看不见的地下城市建设提供准确的三维空间数据底座。基于本文研究成果,以某城市为应用案例,在城市排水管网改造工程、智慧水务云平台建设、智慧管廊施工管理等领域进行了应用,验证了本文研究的可行性、有效性和应用价值。

BIM construction and application of urban underground pipe network

With the in-depth application of surveying and mapping geographic information technology and BIM technology in urban development,the construction of urban underground pipe network BIM has become a necessary link in the construction of smart city and three-dimensional real scene in China.Combined with the application of new basic surveying and mapping in underground space surveying and mapping,this paper puts forward the deep integration technology of underground pipe network surveying and mapping data and BIM,quickly constructs the technical process and system of urban underground pipe network BIM,constructs the refined BIM model under the urban level (GIS) scene,realizes the seamless integration of surveying and mapping data and design data,and opens up the integration channel with surveying and mapping data in multi-disciplinary cooperation,Provide accurate three-dimensional spatial data base for invisible underground city construction.Based on the research results of this paper,taking a city as an application case,its data have been deeply applied in the fields of urban drainage network reconstruction project,smart water cloud platform construction,smart pipe gallery construction management and so on,which verifies the feasibility,effectiveness and application value of this research.
