Design Of The Urban Sewage Pipe Network GIS

With the rapid development of urban construction, the protection of water environment is more and more important and the waste water treatment establishment has been gradually completed. And it brings a lot of data of sewage pipe network and appurtenant works. It is very difficult to manage urban underground network (including the sewage pipe network) by handwork method. It is necessary for modernization city to establish a perfect, exact sewage pipe network GIS (Geographical Information System) to enhance management efficiency and quality of sewage pipe network. Urban sewage pipe network GIS is a new technology to store and manipulate spatial data, integrated with attribute data of sewage pipe network for conveying information to the public and government officials in an easy-to-use GUI (Graphical User Interface) to meet municipal planner's requirement to manage, design and query the sewage pipe networkVisual Basic and GeoMap which is a component GIS software developed by Wuhan GEO Information Science Ltd., are adopted to develop the sewage pipe network GIS, to carry out management and analysis dada of the system by computer in virtue of spatial analysis of GIS. It is divided five modules: I. User management module, II. Draining management module, III. Data management module, IV. Query statistics module, V. Help module.The main function of user management module is to manage all the users. The function of draining management module is to calculate the pipe maximal flux and the average flux by recursion arithmetic and the mixed water quality count, to export kinds of special maps(according to water target, flux and pipe diameter). The function of database management module is for database establishment, database maintenance, data input, data export. The function of query and statistics module is to manager the database of drainage pipe network, which was established by database management module. It includes four parts: data input, data search, data query, data statistics. The function of help module is to offer help for the system users.The thesis is based on the sewage pipe network of Wuhan Zhuankou Economical Development Zone, discussing how to design urban sewage pipe network GIS.
