Abstract

The utility model provides a tunnel section convergence deformation automatic monitoring system. The system comprises a deformation measuring device, when the tunnel section deformation is measured, the deformation measuring device is arranged on the surface of the tunnel lining or inside the tunnel lining, wherein the deformation measuring device comprises a plurality of sensor nipples which areconnected end to end, wherein each sensor nipple can measure to obtain included angle data between three mutually perpendicular directions and the gravity acceleration direction; a deformation data generation module which is connected with the sensor nipple and is used for determining deformation data of the tunnel section according to the included angle data. The tunnel section convergence deformation automatic monitoring system has simple structure, is simple to install, and can realize the multi-dimensional deformation measurement of the tunnel lining. Compared with the monitoring device inthe prior art, the device has light weight, flexible installation mode, low construction safety risk and high monitoring precision, and initial monitoring data is obtained after the installation is completed.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a deformation measurement device for tunnel section monitoring and an automatic monitoring system for tunnel section convergence deformation. Background technique [0002] As a superior form of regional channel connection, tunnels play an increasingly important role. With the large-scale construction of roads and railways, more and more tunnels are newly built and put into operation. Circumferential convergence deformation and vault sinking are important monitoring contents during tunnel construction monitoring and maintenance during operation. This deformation can be known through the displacement of monitoring points arranged on the tunnel lining in the tunnel axial normal plane. [0003] Existing tunnel deformation detection methods generally include: mechanical steel ruler measurement method, Bassett method, total station method and other methods. Among them, the...
