Automatic monitoring of segment strain in Hangzhou tunnel transformation project
Release time:
2024-03-25
Equipment used: vibrating wire surface strain gauge, 16-channel acquisition instrument, 32-channel acquisition instrument, external battery, wireless communication module, signal adapter module.
Project Background
The total length of the tunnel is 3500 meters, and there is no signal in the tunnel.
Construction
The most common problem in tunnel engineering is that the signal is weak or even no signal, so the signal adapter module is used to transmit the external signal to the tunnel, the surface strain gauge is fixed to the position of the design measuring point, and the line guides the position of the acquisition instrument. There is no way to erect solar panels in the tunnel, so 12v external battery is used for power supply. Connect the surface strain gauge wire to the acquisition instrument, plug in the power supply, and adjust the acquisition time to monitor normally.
