Equipment used: vibrating string concrete strain gauge (wire length: distance from buried point to collector), 32-channel collector, wireless communication module, solar power supply system and special accessories.
Project Background
Reinforcement base has been set up
Construction
Before pouring concrete on the bridge deck, tie the concrete strain gauge on the steel cage, lead the wire to the position of the acquisition instrument, and tie the wire on the steel bar with a tie in the middle. Pay attention that the wire is not too tight to prevent the wire from being torn when the concrete solidifies. After the measuring points are arranged, the wire is connected to the collection above. When pouring concrete, the collection frequency should be increased. Always pay attention to whether the change of strain gauge is normal from pouring to concrete solidification. When the concrete is stable, the frequency value collected is taken as the initial value, which is compared with the first time in future observations.
