Application On The Drainage Network Hydraulic Model In The Drainage System’s Operation And Management Based On Infoworks

Drainage network system is one of the most essential infrastructure in city， isthe major projects to projects to protect public health security，prevent waterloggingand control water pollution,which responsible for collecting， conveying city’sdomestic sewage， industrial wastewater and stormwater． With the acceleratingprocess of urbanization in China，the design，operation and management of traditionaldrainage system can not suffice the requirements in many cities，which needs to meetthe process of modern urbanization and the development of economic rapid．Drainagenetwork hydraulic model，can use modern hydrology，hydraulics to simulate urbandrainage network system’s operation，control the running laws of urban drainagenetwork，optimize urban drainage network system’s design and planning，operationcontrol，maintenance management，rebuilding expansion，etc．It has very importtantsignificance to solve the problems of drainage network in China．Subject to G city’s drainage network system project，uses the internationaladvanced drainage hydraulic simulation software InfoWorks CS，the research wants tocomplete hydraulic model building works in G city’s DS system． The modelsimulation assist in solving DS system’s current problems，such as network silation，sewage overflow，storm sewage mix，uneven sewage collecting and so on．The thesis introduce the concept，classification and application of the modelsimulation for urban drainage network system， review the hydraulic modeldevelopment and research of the drainage system in domestic and foreign，summed upthe features and benefits of InfoWorks CS software，investigate the theoretical basisand technology route of drainage pipelinessystem deeply．Combined with engineering examples，the paper uses InfoWorks CS software tobuild DS sewage treatment system hydraulic model’s in G city． Main researchcontents include:import DS area’s hydraulic modeling data，build and check thenetwork topology structure，set and optimize the model parameters and boundaryconditions，monitor the level，flow，velocity of key inflow points，calibrate andsimulate the model for application．On the basis of complete model about the urban sewer system， the model is applied to the operation control， maintenancemanagement of urban sewer system modeling in DS system of GZ city．Throughmodel calculations,assess the prevent status of DS system accuratly，optimize therunning of the sewage pumping station， develop a pumping station linkageprecipitation program to low the lever．They have a demonstrable effect on preventingthe overflow in the dry season and optimizing operation and management．In conclusion，the achievement of this paper not only provides a scientific basisand reference to design and manaement for G city’s drainage network system，but alsofits to other cities．...
