Real-time monitoring and early warning system for a subway station foundation pit, and a monitoring and early warning method thereof

Abstract

The invention discloses a real-time monitoring and early warning system of a subway station foundation pit and a monitoring and early warning method thereof. The monitoring and early warning system comprises an on-site sensor arranged in the foundation pit. The field sensor transmits the acquired foundation pit data to a front-end data acquisition module and a front-end data processing and transmitting module; the front-end data processing and transmitting module is used for transmitting the data to a data processing center and a foundation pit monitoring and early warning management platform, and the foundation pit monitoring and early warning management platform is connected with a foundation pit BIM model to realize corresponding mapping of the measurement data in the model; the monitoring and early warning method comprises the following steps that a foundation pit excavation time-varying BIM model is built, a control network is built, information interaction is carried out, real-time visual monitoring of the BIM model 4D is achieved, the foundation pit monitoring and early warning management platform carries out calculation and analysis according to actual measurement data, and construction process simulation or prediction analysis is carried out. According to the method, through the BIM technology, the dynamic processes of foundation pit excavation, support system construction and construction equipment are closely connected with foundation pit monitoring to form a whole.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pit construction engineering related to foundation excavation of urban subway stations, and specifically relates to a real-time monitoring and early warning system for foundation pits of subway stations and a monitoring and early warning method thereof. Background technique [0002] At present, my country's urban rail transit planning and construction has entered a period of vigorous development. The construction of subway projects is faced with various geological and hydrological conditions, and it is inevitable to pass through a large number of sensitive urban construction facilities and lifeline systems in the city. Under the influence of complex environments, the existing underground and above-ground structures have high uncertainties, and are high-risk production both at home and abroad. Activities and engineering construction risks are prominent, which can easily cause serious econom...

AI Technical Summary

Problems solved by technology

These methods cannot timely reflect the abnormal changes of the foundation pit engineering during the construction process, and have great interference to the construction and are dangerous to the monitoring work.

[0006] In view of the fact that traditional technology is difficult to meet the real-time and integrated requirements for construction safety control, there is an urgent need for a safety integrated control system and a dynamic comprehensive early warning method that integrates automatic continuous monitoring and real-time early warning.
