A system and method for monitoring underwater settlement and deformation during tunnel excavation

Abstract

The invention discloses a monitoring system and method for underwater settlement deformation during tunnel excavation, including a monitoring data acquisition layer, a data communication storage layer and a user presentation layer. The monitoring data acquisition layer is responsible for collecting field data and transmitting data through wireless to the data communication storage layer; the data communication storage layer includes a communication controller and a database as a cloud server; the user presentation layer adopts a server or a mobile terminal for data query, analysis and processing, which includes a data query module, Table query module, working condition query module, data analysis module and alarm statistics module. The settlement monitoring device includes a rigid rod, a CCD camera, a scale and several cement piles, a rigid rod is arranged between every two cement piles, and the settlement is monitored by the pointer at the front end of the rigid rod to indicate the change of the scale. The invention transmits data wirelessly, conducts non-contact measurement in the whole process, is convenient and simple to lay out, and does not affect normal navigation on the water surface.

Description

A system and method for monitoring underwater settlement and deformation during tunnel excavation technical field The invention belongs to the field of civil engineering, relate to a kind of settlement automatic monitoring technology, be specifically related to a kind of tunnel excavation A system and method for monitoring the deformation of the bottom settlement during the process. Background technique [0002] The rapid development of urban subway construction has eased the urban traffic pressure and brought increasingly prominent tunnels. Excavation and operation safety precautions, tunnel deformation monitoring technology came into being. Its safety monitoring content mainly includes tunnel erosion Monitoring, tunnel structure monitoring and stratum monitoring, then the tunnel settlement and deformation, especially the settlement caused by the tunnel excavation under the water body Deformation has always been the focus of monitoring, and the measurement methods of...

Problems solved by technology

Its safety monitoring content mainly includes tunnel erosion monitoring, tunnel structure monitoring and stratum monitoring. The settlement and deformation of tunnels, especially the settlement and deformation caused by excavation of tunnels under water bodies, has always been the focus of monitoring. Retesting and uninterrupted measurement are mainly caused by the on-site installation of advanced instruments. The cost is high and the real-time performance is poor. In addition, the processing of traditional monitoring data is mainly done manually. The data processing efficiency is low, and the feedback of data results is not timely, which is not conducive to the analysis of monitoring data. and monitoring and forecasting, affecting engineering decision-making
