Urban Underground Pipeline Detection And Underground Pipeline Information System

The city underground pipelines are the city's important infrastructure, The basic data of the underground pipelines is a important basis for urban planning, design, construction and management. The underground pipelines include tap water pipelines, storm sewer, waste pipe, gas pipelines, electricity pipelines , telecommunication pipeline and so on. It's very important to investigate the underground pipelines and establish the city underground pipelines information system. managing the underground pipelines efficiently, may bring the huge economic efficiency and the social efficiency to the city.In this thesis,at first, the author analize the existing pipe network administraction methods. Then, unifies Shenzhen underground pipelines exploration project, discusses the principle, method and the technology of the underground pipelines exploration . The basic principle and application of the electromagnetic wave and the geology radar sounding method are emphasized. With the engineering of telecommunication pipeline cross section sift of Shenzhen city as background, it discusses the demand, methods, technique and contents of telecommunication pipeline cross section.The data is the core of GIS. The high accurate data is the important guarantee for GIS production quality. In this article, The methods of data collection, data processing, database creation and data quality control are introduced in detail.Base on the existing management technology in GIS, The author discusses the goal of the city underground pipelines management information system, and discusses the system design's basic principle from the view of software engineering. The methods of the system exploitation and the choice of developed platform are Discussed. Finally using DELPHI language as developmemt language, ARC / INFO platform and COM technology, developed a underground pipelines PIPENET system. The system main functions and the technology methods of the system realization are introduced . The system has a strong database administration function, the PIPENET can produce several kinds of tables and underground pipelines MAP automaticaly.Finally, the whole summary is given about the underground pipelines exploration and the underground pipelines management information system. The existing insufficiencies and further studies are pointed out.
