Rapid BIM design method for overhead line system

Abstract

The invention discloses a rapid BIM (Building Information Modeling) design method for an overhead line system, which is used for greatly improving the BIM design efficiency of the overhead line systemand effectively reducing occupied resources. The method comprises the following steps: (1) establishing a contact network two-dimensional plane arrangement diagram; 2, establishing a node library forstoring key node information; (3) establishing a BIM model library for storing various BIM models with different sections of the whole line; (4) establishing a mapping library for storing a mapping relationship between the key nodes and the section BIM model; (5) calling a BIM model library; (6) catenary BIM design: designing, modifying and perfecting the called BIM sections according to the actual conditions of different positions, and connecting different sections to complete the catenary BIM design, so as to obtain a professional BIM model of the whole catenary; and (7) importing the BIM collaboration platform, transferring the contact network BIM model to a unified accurate measurement network coordinate of the BIM collaboration platform, and automatically fusing the contact network BIM model into each professional BIM model.

Description

technical field [0001] The invention relates to rail transit, in particular to a rapid BIM design method for catenary. Background technique [0002] BIM (Building Information Modeling) technology is a digital tool applied to engineering design, construction, and management. Through the integration of building data and information models, it can be shared in the whole life cycle of project planning, operation and maintenance. and transmission, so that engineering and technical personnel can correctly understand and efficiently respond to various building information. BIM has been widely recognized around the world. It can help realize the integration of building information. From design, construction, operation to the end of the building's life cycle, all kinds of information are always integrated in a 3D model information database. The design team, construction Units, facility operation departments and owners can work together based on BIM to effectively improve work effici...

Problems solved by technology

[0003] BIM has been successfully used in rail transit catenary design. At present, the catenary BIM design method is generally used to complete the catenary BIM design on a unified platform based on line data. Although this method is convenient for professional collaboration, the established The BIM model is often too large and takes up a lot of resources, and the BIM design of the catenary can only be started after the BIM modeling is professionally completed in front of the line and other stations, which will inevitably lead to design waiting and low design efficiency

On the other hand, during design optimization, it is necessary to modify the catenary BIM models at different locations one by one, which further reduces the efficiency

[0004] In summary, the existing BIM design methods have problems such as large temporary resources and low design efficiency, which have become one of the main factors restricting the development of BIM design
