Early warning and real-time control of construction safety risk of underground engineering based on building information modeling and internet of things

The objective of this study is to establish a safety risk warning system for the construction of underground engineering and to solve the problems existing in current construction of underground engineering, such as large investment, long construction period, complex construction environment, and many unforeseen risk factors. In this research, building information modeling (BIM) technology and Internet of things technology are used to analyze the construction of safety risk warning system for underground engineering. Firstly, the concept and application of BIM technology and safety risk warning of underground engineering construction are introduced. Then, aiming at the existing safety problems of underground construction, the construction principle of underground construction safety indicator system, the establishment steps of indicator system and safety risk indicator system are introduced in detail, and a set of early warning and control system of safety risk of underground construction based on BIM technology and Internet of things technology is established. At last, the working mode and real-time monitoring of underground engineering early warning based on BIM technology and Internet of things are expounded. The results show that the underground engineering prediction system based on BIM technology and the Internet of things adopts the working mode that combines the circular safety risk warning wheel mode and the three-dimensional safety risk warning mode. Moreover, the real-time dynamic monitoring of the security risk warning system can be achieved through the periodic recording and testing of process indicators by the BIM management platform. It is hoped that this study can provide a good management platform for underground construction safety and reduce the occurrence of safety accidents in underground construction.
