Application Research Of Urban Drainage Ditch And Surrounding Ecological Landscape Reconstruction Based On BIM Technology

Twenty years ago,the emergence of CAD transformed engineering drawings into 2D data,which became the first revolution in the field of engineering construction.BIM,Building Information Modeling.Using 3 d three-dimensional digital model of construction project,the implementation of 3 d model and actual construction engineering information consistent and sharing,improved the unpredictability of the problems in the process of engineering project in the implementation and errors,and to manage the whole life cycle of the project,become the second revolution in the field of engineering construction.Nowadays,BIM technology is not only used in the project design and planning stage,but also widely used in supervision,construction,maintenance and other construction links.Its digitization,the information new technology,also will face the huge development opportunity.Urban drainage ditch is an important part of urban water system.With the development of cities,many cities have renovated and made relevant flood control plans.Although the flood control and flood discharge functions of urban drainage ditches are satisfied,urbanization development is in contradiction with the ecology of urban drainage ditches.After the transformation,there are still many problems such as ecological degradation and poor landscape form.In addition,the late operation and maintenance management system is not perfect,and the urban drainage ditches and the surrounding ecological landscape are destroyed and deserted for the second time.At present,more and more citizens have higher requirements for living environment and new requirements for ecological landscape around urban flood drainage ditch.Therefore,the core of urban flood drainage ditch governance is the harmonious coexistence relationship between urban digital information construction,flood control,sewage discharge and ecological landscape.The urban drainage ditch in Lanzhou city connects the Yellow River to form the urban channel structure of "fish skeleton",which is the main safe flood discharge channel in Lanzhou city.BIM technology is introduced to provide dynamic 3D model foundation for intelligent and informationized operation and maintenance management of lanzhou city's urban flood drainage ditch.Intelligent management platform is adopted to realize the intelligent management of Lanzhou city's urban flood drainage ditch.Taking the development of BIM technology in other industries as a reference,this paper proposes the realization approaches of BIM technology in urban flood drainage ditch and surrounding ecological landscape transformation.In actual project as an example,the use of CAD,Revit,Fuzor,Naviswork software builds having groove around the site,roads and ecological landscape with professional characteristics,such as information model,implementation different construction stages of information transfer and sharing,and combined with actual project simulation collision check and plan are summarized and the deepening of the construction of nodes and the cost optimization applications.Finally,through the application of BIM technology in actual project transformation design,put forward based on BIM technology having groove and the surrounding urban ecological landscape visualization management platform of operational mode,citing city having groove visualization based on BIM technology operations management platform should have the specific functional requirements,maintenance and management for real-time monitoring,emergency warning,warning functions such as demand,to achieve information for flood control,power,wisdom construction of city for subsequent city having groove operations research work provide certain reference and reference.
