In view of the problem of the limitation of the traditional two-dimensional design method and the presentation for the miter gate,combining with the Qingshan ship lock project in the Lishui River,we design the miter gate based on the BIM characteristics of modular,parametric and collaborative,create BIM models of miter gates,carry out collision checking,engineering drawings export,and automatic engineering quantity statistics,and generate a variety of visual design results.The application can reduce the design intensity of the designers,and effectively avoid the design changes and rework problems.Compared with the traditional 2D design mode,the use of BIM technology for the miter gate design can effectively improve the design efficiency and quality of drawings,reduce the cost of communication,control the cost of the project.
