Abstract: A tunnel defect detection and management system based on a vibration signal of a moving train. This system identifies the defects in a subway tunnel structure and soil behind a wall through the acquisition, transmission and analysis of an on-board acceleration signal. A signal acquisition sensor is mounted on the moving train. A signal acquisition module and a signal transmission system are mounted in the train to preprocess and compress the signal. A data processing and analysis server performs data analysis to quickly identify the defects of the tunnel and the auxiliary structure thereof, and determine a defect location and type. A tunnel management platform releases real-time detection information and health status of the tunnel, alarms for the defects, and releases the defect data to relevant personnel to take measures.

Abstract: The present invention relates to a loaded-to-frame detection equipment for backfill grouting of a shield tunnel, including an automatic loaded-to-frame transmission apparatus, a ground penetrating radar, and an intelligent backfill grouting processing and analysis software. The equipment is integrated by using software and hardware, and can implement real-time visual detection of a backfill grouting layer in a shield construction process. The loaded-to-frame automatic transmission apparatus mainly includes a track, a synchronous belt, a transmission mechanism, a servo machine, and a drive and reducer; and a new air-coupled radar detection apparatus is carried on the loaded-to-frame automatic transmission apparatus and is installed on a shield frame. With the shield performs tunneling, circular detection on a grouting body of the shield and visual layered display of the grouting body are implemented.
