Large-span bridge construction monitoring and managing system based on BIM technology

Abstract

The invention discloses a large-span bridge construction monitoring and managing system based on a BIM technology. The large-span bridge construction monitoring and managing system includes a BIM generation module, a basic information setting module and a working condition managing module; the BIM model generation module is used for establishing BIM models of a plurality of bridges, and a B / S framework is adopted to achieve display, operation and data management of the BIMs of the bridges, wherein the BIM of each bridge corresponds to one project; the basic information setting module is used for setting monitoring plans, equipment information and measure-point information for all the projects; a GIS technology is adopted to achieve positioning of geographic locations of the projects; the working condition managing module is used for displaying construction working conditions in each stage of the projects through combined usage of the functions of selecting and superposing current working conditions of the projects. By the adoption of the large-span bridge construction monitoring and managing system based on the BIM technology, construction schedules of the bridges can be observed through three-dimensional models or three-dimensional animated show, and dynamic changing processes of construction are displayed visually.

Description

technical field [0001] The invention relates to the field of bridge design, in particular to a BIM technology-based monitoring and management system for large-span bridge construction. Background technique [0002] With the rapid development of high-speed railways, my country has successively built a number of representative long-span bridges for railways or highways and railways, such as Wuhan Tianxingzhou Yangtze River Bridge and Nanjing Dashengguan Yangtze River Bridge. In the construction process of long-span bridges, there are many situations such as long construction period, complex construction technology, variable construction conditions, frequent occurrence and high severity of safety accidents, and the engineering management is difficult. Therefore, it is necessary to strengthen the construction monitoring and management of long-span bridges. [0003] In the construction management of bridges, some management systems based on two-dimensional platforms were initiall...

AI Technical Summary

Problems solved by technology

[0007] 1. The display of the model is not intuitive: In traditional construction activities, the construction is generally carried out with flat two-dimensional drawings, but the drawings have the disadvantage of insufficient three-dimensional effect, unlike the three-dimensional model that can be intuitively displayed in front of the construction personnel; through traditional The horizontal bar diagram shows the construction schedule, and it is difficult to clearly express the dynamic change process of the construction

[0008] 2. The means of information exchange are backward: two-dimensional drawings are used as the main carrier of information, which is not easy to carry, transmit and store. When information is transmitted and exchanged, it is easy to cause ambiguity, distortion and errors, and it is difficult for non-professionals to understand, resulting in confusion in the bridge construction process. The workload of information transmission at each stage is heavy and the efficiency is low; at the same time, there are "information islands" among various application software in the construction process

[0009] 3. Only limited to single project management: At present, the application of BIM technology in bridge construction management is based on a single project, and the compatibility is poor, which leads to the repeated construction of the system platform for each project, which not only has a large workload, but also wastes time and manpower Material costs, and data sharing between projects is not possible

[0010] 4. Weak general functional modules and incomplete workflow: only limited to the monitoring modules of the bridge profession itself such as alignment, stress, environment and other indicators monitoring, lack of some general management modules such as working condition management, personnel management, equipment management, documentation Management, etc., unable to form a complete workflow

[0011] 5. Failing to realize the collaborative work of all parties: only for the construction monitoring party, and does not involve other personnel such as the supervisor, construction party, etc., and cannot satisfy the collaborative work of all parties
