Deep and large foundation pit intelligent monitoring system based on Internet of Things and BIM three-dimensional modeling

Abstract

The invention provides a deep and large foundation pit intelligent monitoring system based on Internet of Things and BIM three-dimensional modeling, and belongs to the technical field of deep and large foundation pit construction. The system comprises a detection subsystem, a data transmission subsystem and a data summarization processing subsystem, wherein the detection subsystem is used for detecting and outputting data information of foundation pit inclinometry, axial force, displacement, water level and inclination of adjacent buildings; the data transmission subsystem is used for transmitting data information of the detection subsystem to the data summarization processing subsystem; and the data summarization processing subsystem is used for automatically storing and analyzing the received data information, outputting a monitoring report and automatically sending early warning information. The system is good in timeliness, high in efficiency, low in cost, convenient to use and good in practicability.

Description

technical field [0001] The invention belongs to the technical field of deep and large foundation pit construction, and in particular relates to an intelligent monitoring system for deep and large foundation pits based on the Internet of Things + and BIM three-dimensional modeling. Background technique [0002] Foundation pit engineering is one of the most time-consuming, costly and risky sub-items in construction projects. According to statistics, in 2019, there were 773 safety accidents in municipal projects across the country and 904 people died, of which accidents related to foundation pit engineering accounted for more than 70%, and the safety situation is still very severe. For this reason, the Ministry of Housing and Urban-Rural Development issued a document emphasizing the setting of earthwork and foundation pit collapse as key prevention and control targets. The construction of foundation pits is very complicated, there are many unknown hidden dangers, and it is dif...

Problems solved by technology

The automatic monitoring method of the foundation pit realizes the real-time dynamic monitoring of the deformation of the foundation pit, and solves the shortcomings of the existing manual monitoring method, such as heavy workload, slow feedback speed, and poor ability to deal with emergencies. However, this technology is still in its infancy in China. , there are still several key problems to be solved: 1. A complete automatic monitoring system for foundation pits has not yet been established, and some key automatic monitoring equipment still needs to be developed; 2. An intelligent data management system has not yet been established, and data analysis and monitoring and early warning mainly rely on Manually, the timeliness of monitoring data cannot be fully utilized; 3. The utilization rate of monitoring data is low, mainly used for making reports, but not applied to BIM 3D visualization modeling, which is not conducive to intuitively grasping the construction process and deformation information of the foundation pit
