[Abstract]:Based on the background of Chongqing Putan Yangtze River Bridge, aiming at the difficulties in the process of construction, such as poor communication of information, prominent contradiction of interface management and high requirement of data collection accuracy, the construction control platform of super suspension bridge based on BIM is constructed in this paper. Through the combination of BIM technology and database construction, network communication and industrial control technology, the dynamic management of construction process and the communication of information integrity are realized. In order to achieve the purpose of assistant management and decision making, the main research contents are as follows: 1) aiming at the information communication obstacle faced by the information management of construction project at present, combining the advantages of BIM technology in information transmission and work cooperation, This paper probes into the solution of information management based on BIM technology, analyzes the requirements of the construction control platform of BIM from the technical level and the application layer, combining with the construction characteristics and difficulties of the bridge. On the basis of establishing SQL Sever relational database, the author chooses BIM software such as SQL Sever to develop extensibility, and uses C / S network structure to build visual design ability. Dynamic simulation function, graphic editing platform of data analysis and processing function, the overall module setting of the platform is determined according to the management objectives in construction, and the corresponding relation between model component information and field information is determined. Virtual simulation, schedule optimization, schedule real-time tracking and other functions of the progress module are studied, the schedule management framework and working principle based on BIM are expounded, and the schedule sub-function module in the BIM construction control platform is set up in detail. This paper expounds the complete workflow of the schedule module, and verifies the advantages of the process in modeling, planning optimization and real-time schedule control according to the quality control framework based on BIM. The overall application value and work flow of quality module in BIM platform are studied, and the quality control points such as virtual construction, positioning system, quality tracking and quantity supply are put forward according to the engineering background of Putan Bridge. In order to solve the problem of temperature control in the construction of super large volume concrete of north Anchorage of Putan Bridge, this paper makes use of control computer, temperature data acquisition equipment, automatic control valve circulating water pump, and sets it as BIM construction control platform quality control sub-module. The temperature measurement and control system is built by wireless network communication and bridging equipment, and the automatic control of concrete temperature is accomplished by establishing temperature warning mechanism and combining with Modbus protocol. The temperature change of concrete in the corresponding temperature measuring point is reflected by three dimensional form synchronously and intuitively, and the working flow of temperature control module is analyzed, and the practice is carried out in the construction of large volume concrete in the north Anchorage. The advantages of temperature control module in improving working efficiency and refinement of temperature data are demonstrated.
