Design And Development Of Urban Underground Three-Dimensional Pipeline Management System

From the perspective of urban infrastructure,urban underground pipelines are one of the important parts,mainly composed of gas and electricity,all over the streets and alleys of the city.The role of urban underground pipelines is to transport the energy and information of the city,and lay a foundation for the survival and development of the city in terms of material.For the construction of digital cities,the information of its attributes and space has become the basic information.Underground pipelines play an important role in urban construction,planning and management,and are known as the “lifeline” of the city.Therefore,conduct a general survey of urban underground pipelines,identify all pipelines including materials,strikes,and depths,build a three-dimensional pipeline management system,implement information management,and disorderly construction in the urban construction process.It is the circumvention of repeated excavation and other phenomena,so that the city can achieve a higher level of digitization,which is the most important task of urban construction.Based on the actual work of the underground pipeline survey and exploration project in Qinhuangdao City,this paper studies and develops the three-dimensional management system of urban underground pipelines,and consults a large number of documents to carry out the following work: 1.Describe the background of this paper and the development of three-dimensional management system of underground pipelines at home and abroad.And the status quo,and introduces the related software that is widely used in the market;2.Describes the methods and related theories of 3D GIS technology and 3D pipeline modeling,and introduces the design and construction of pipe network database and 3D of pipe network in detail.The process and method;3,this paper revolves around the plug-in underground pipe network three-dimensional management system,introduces the overall design,development environment,development process,etc.,and developed the query statistics plug-in,pipeline space analysis plug-in,pipeline data management plug-in,three-dimensional Plug-ins such as scene browsing plugins.Finally,the research content and significance of this paper are summarized,and the future pipeline 3D management system is prospected.
