Rapid refined modeling method for municipal pipe network by using BIM (Building Information Modeling)

Abstract

The invention provides a rapid refined modeling method for municipal pipe network by using BIM, which comprises the following steps of: analyzing a regional map of which a pipe network needs to be established and related data, carrying out preliminary modeling through map analysis, establishing a rough BIM model through Cill 3D software, segmenting the model, respectively extracting component diagrams and model lines in the model, respectively segmenting a component diagram and a model line, limiting the position of the segmented component diagram according to needs, adjusting the height and the relative position of pipe network distribution by the model line, parameterizing the component diagram according to requirements, colliding the model line with the component diagram, and carrying out optimizing, establishing a standard model of a municipal pipe network, generating a specific and complete processing drawing, and generating corresponding data among all parts. Compared with the prior art, the method has the advantages that BIM modeling is faster, and the built model is higher in refinement.

Description

technical field [0001] The present invention relates to the technical field of BIM, and specifically refers to a rapid and refined modeling method of a municipal pipe network using BIM. Background technique [0002] BIM is a technical means of visual digital expression of the physical and functional characteristics of engineering projects, providing efficient, collaborative, and visual technical application support for the entire process of engineering projects from design, construction to operation. At present, BIM technology has become a popular information technology in the field of engineering construction such as construction, water conservancy, highway and railway transportation infrastructure. In the field of engineering construction, BIM technology has become a means for enterprises to refine management, reduce emissions and increase efficiency, and enhance competitiveness .

AI Technical Summary

Problems solved by technology

[0003] Due to the complexity of pipelines in underground space, a large amount of data needs to be reviewed. For designers, the problem of collision between pipelines is difficult to completely avoid. In many cases, it is only discovered during the construction process, resulting in a waste of resources.

In the field of municipal engineering construction, the construction of a 3D model of the municipal pipe network that can comply with my country's municipal engineering layout specifications is the basic key technology for the application of BIM technology in municipal engineering construction. Although the international mainstream brand 3D BIM software realizes the municipal pipe network BIM modeling, it is still There are problems of low modeling accuracy and low modeling efficiency, so a 3D fast and refined modeling method using BIM technology is needed
