Foundation pit monitoring, early warning and construction management D-BIM platform integrated with Beidou high-accuracy positioning system

Abstract

The invention discloses a foundation pit monitoring, early warning and construction management D-BIM platform integrated with a Beidou high-accuracy positioning system. Firstly, through the foundationpit D-BIM platform, the excavation progress of a foundation pit, construction of a foundation pit supporting and protecting system and the influence of surrounding buildings on construction of the foundation pit are reflected in real time; secondly, a real-time monitoring system is composed of the Beidou high-accuracy positioning system, mapping equipment, a stress-strain sensor, a groundwater stage gauge and the like, monitoring signals are collected by the D-BIM platform in real time, and a database is built; thirdly, monitoring data of the foundation pit deformation database can be directly retrieved and analyzed through the D-BIM platform, and when the monitoring data are larger than an early warning threshold value, an alarm is directly given out; and fourthly, the D-BIM platform cantransmit a model to software of finite element analysis in real time, and the foundation pit supporting and protecting system, groundwater movement and the stability of the foundation pit are analyzed and forecasted. According to the foundation pit monitoring, early warning and construction management D-BIM platform integrated with the Beidou high-accuracy positioning system, the correlation between the supporting and protecting structure and the stability of the foundation pit in the construction process can be visually displayed through the D-BIM model, early warning is achieved for potential safety hazards, and field management decision makers can be effectively helped to find problems and take corresponding remedial measures.

Description

technical field [0001] The invention belongs to the field of civil engineering construction, and is a dynamic foundation pit monitoring and construction management, in particular a foundation pit monitoring, early warning and construction management D-BIM platform integrated with a Beidou high-precision positioning system. Background technique [0002] Whether it is a modern high-rise, super high-rise building or an urban subway station, it involves the excavation of deep foundation pits. These buildings are generally located in the center of the city, with dense buildings and complex and changeable surrounding environments, making dynamic monitoring of foundation pits in the above buildings Indispensable in the process of foundation pit construction. [0003] Most of the foundation pit deformation is caused by the uneven progress of local construction. If the structural strength of the support system meets the load requirements, the stability of the entire foundation pit ca...

Problems solved by technology

However, the existing BIM model ignores the dynamic changes of the entire foundation pit and cannot reflect the characteristics of real-time changes in the construction process.

[0005] Invention patent "A BIM-based foundation pit deformation monitoring and early warning platform during construction" (Patent No.: 2017104403560) Although it reflects the dynamic management of foundation pit construction and monitoring, it does not reflect the dynamic process and is not an independent visual management platform
