Analysis On Key Technologies Of Urban Underground Pipeline Detection

Urban underground pipeline is related to economic construction,urban development,public interests,social harmony,as the city's meridians and blood.It is an important part of digital city and intelligent city construction to carry out the census and exploration work of urban underground pipeline and establish perfect and accurate underground pipeline information.Based on AutoCAD,the establishment of scientific and perfect underground pipeline information management system is the most common way to establish pipeline information management system in most cities.Therefore,based on the secondary improvement of existing pipeline information system,the development of urban underground pipeline Has a vital role.In this paper,combined with the new district pipeline survey project,the underground pipeline exploration theory and method of key technology analysis,as follows:Firstly,this paper summarizes the significance of urban underground pipeline to the current urban development and the research status of urban underground pipeline at home and abroad by consulting a large number of relevant literatures.Discussed from three aspects underground pipe network,pipe network detection theory and pipeline detector.Then,the principle and method of underground exploration of urban underground pipeline are expounded,and four methods of electromagnetic method,magnetic detection method,geological radar method and seismic wave method are deeply discussed.The general requirements of the pipeline survey,the contents of the pipeline survey conducted a corresponding overview.Combined with the existing common detection method,starting from the principle of urban underground pipeline detection,according to the new area of underground pipeline detection characteristics and processes to the principle of analysis and case verification combined with the way,the real electromagnetic induction method,Ground radar method and other methods applied to the specific road pipeline detection,and achieved a good detection effect.Finally,the key technologies such as pipeline data processing and system management of pipeline information are discussed in depth.Based on AutoCAD,the secondary development of the pipeline information system "Census Star 2015" of the new district pipeline survey is combined with the actual pipeline detection data of the new district,and the data storage and pipeline mapping have been improved.Taking the project of the New District pipeline project as an example,this paper starts from the actual pipeline project,analyzes the measurement technology and the combination of the technology used in the survey of the pipeline industry,and innovates in the storage and mapping of the pipeline data.The New District pipeline survey project provides help for the pipeline information system construction to provide some reference.
