Problems solved by technology

At the same time, traditional convergent gauges need to interrupt the traffic or production of tunnels and roadways during the measurement process. Therefore, the measurement frequency is limited; the measurement data needs to be processed and analyzed before the roadway deformation data can be obtained. If the post-processing of the data is not timely, there may be delays The best time to strengthen and maintain the support body
