Four-dimensional bridge information management system based on bim technology

Abstract

The present invention is a four-dimensional bridge information management system based on BIM technology, and uses Revit software to build a three-dimensional model of a bridge, including: an information acquisition module for acquiring basic information related to the bridge, disease information of bridge diseases, and maintenance and repair information related to the bridge, The corresponding information is converted into a system format; the disease information reading module obtains the disease information and discriminates its type, and generates a three-dimensional solid model of the disease in the three-dimensional model of the bridge; the generation module of the four-dimensional model of the disease includes the disease information according to different times. The stage is associated with the 3D entity model of the disease; the bridge information management module, after lightening the 3D model of the bridge and the 4D model of the disease, obtains the 3D information model of the bridge including the disease information, maintenance and repair information, basic information and the 3D model of the bridge at each time stage. . The system integrates the basic information of the bridge, the disease information at different times, and the maintenance and repair information at different times, which makes bridge evaluation and decision-making more convenient.

Description

technical field [0001] The invention relates to the field of bridge maintenance management, in particular to a four-dimensional bridge information management system based on BIM technology. Background technique [0002] At present, the development of infrastructure construction in my country is in full swing, and many different types of bridges have appeared rapidly in recent years. However, in the traditional project management, the basic information management of bridges is still stored in the form of electronic documents and printed books, which makes it extremely difficult to read and use later. [0003] During the service process of bridges, it may experience five types of maintenance management, including minor maintenance projects, intermediate repair projects, major repair projects, improvement projects and special projects. Among them, small repairs and maintenance carried out on a monthly basis, medium repairs carried out on a yearly basis, and even major repairs ...

AI Technical Summary

Problems solved by technology

Among them, minor repairs on a monthly basis, medium repairs on a yearly basis, and even major damage repairs, improvements to bridge grades, and special projects will generate a lot of information that needs to be managed. Electronic form records and displays are not intuitive, and the information is scattered and lacks unified management, which makes bridge maintenance management and subsequent information query and use ineffective.
