Monitoring method of pipe jacking construction process based on BIM technology

Abstract

The invention relates to a monitoring method of pipe jacking construction process based on BIM technology, Adoption of monitoring system, the system comprises an information preset module, monitoringinformation acquisition module, BIM model import module, monitor information processing and analyze module, data storage module and monitoring information output module. That method comprises the following step: basic information preset, caisson, pipe jacking, monitoring point BIM modeling, monitoring information collection, establishing MDB data file and database center MYSQL, monitoring management interface composition, monitoring point data analysis. The invention can be used for the visual management of the monitoring data in the tunnel construction process, the monitoring data in the pipejacking construction process can be viewed in real time and intuitively, and the related monitoring data can be displayed simultaneously according to the monitoring data analysis, so as to facilitatethe judgment and decision-making of the site management personnel. So as to effectively solve the project data is not intuitive, poor correlation between the data, to ensure the safety of the construction process, to improve the visualization and informatization level of pipe jacking construction process monitoring.

Description

technical field [0001] The invention relates to the field of safety monitoring during tunnel construction, in particular to a monitoring method and system for the construction process of pipe jacking based on BIM technology. Background technique [0002] As a typical construction technology of urban trenchless (underground excavation) technology, pipe jacking construction is widely used in urban pipeline construction because it has little interference from the external environment, has little impact on the surrounding environment, and has a high degree of construction automation. Due to the adoption of pipe jacking construction in dense areas of large and medium-sized cities, it will inevitably cause construction disturbance to the soil around the pipeline, and then interfere with the normal operation of surrounding buildings (structures). effects have also received widespread attention. [0003] At present, the monitoring of pipe jacking mainly focuses on the analysis of s...

AI Technical Summary

Problems solved by technology

[0003] At present, the monitoring of pipe jacking mainly focuses on the analysis of some data in the construction stage, such as segment stress and soil settlement. By drawing deformation curves and setting alarm values, it is convenient to guide the construction process; secondly, it is aimed at the safety of tunnels in the operation and maintenance stage. Carry out data monitoring; finally, the monitoring system based on the BIM model is mostly concentrated in the process of building construction, foundation pit engineering and shield construction, and is difficult to be directly applied to pipe jacking construction

Therefore, a systematic monitoring and management system has not yet been formed for the safety monitoring of the pipe jacking construction process, and the level of visualization and informatization is low
