Real-time monitoring method, device and system for bridge pushing structure

Abstract

The invention is suitable for the technical field of bridge construction, and provides a real-time monitoring method, device and system for a bridge pushing structure, and the method comprises the steps: obtaining the current bridge position information of a target bridge and the actual measurement data of at least one bridge monitoring point; inputting the current bridge position information of the target bridge into a preset three-dimensional visualization model; determining current attitude information of the target bridge; inputting the current attitude information of the target bridge into a preset bridge finite element model to obtain a theoretical monitoring threshold of each bridge monitoring point of the target bridge under the current attitude; and monitoring the first bridge monitoring point in real time according to the measured data of the first bridge monitoring point and the theoretical monitoring threshold. By comparing the measured data with the theoretical monitoringthreshold, whether the pushing mechanism has errors or not can be determined in real time, so that real-time monitoring and deviation rectification of the bridge pushing mechanism are realized, and the monitoring efficiency of the bridge pushing mechanism is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a real-time monitoring method, device and system for a bridge pushing structure. Background technique [0002] With the development of bridge construction technology, construction monitoring has gradually been paid attention to, especially for bridges with large volume or difficult construction, construction monitoring is particularly important. Nowadays, bridge construction monitoring is not only an important part of bridge construction technology, but also relatively difficult. [0003] Traditional monitoring methods usually use sensors to collect data such as deflection, jacking force, and stress at bridge monitoring points, and then manually analyze these measured data to determine whether there are errors in the bridge pushing process. This manual analysis method is time-sensitive. Poor, thus causing the problem of slow construction progress. Conte...
