Summary: | The invention provides a tunnel lining gridding fine detection method and system based on an ultrasonic technology, and the method comprises the steps: enabling a phased array ultrasonic detection device and a gridding fine detection trolley to be integrated as a fine detection scanning mechanism of a tunnel lining structure, and carrying out the full-coverage scanning of a tunnel lining in a manner of annular and longitudinal combined scanning, and collecting the internal data of the lining; during scanning, data obtained through detection are uploaded to a field detection host and a remote server system in real time; and performing three-dimensional reconstruction on lining internal data of each grid obtained through detection based on the spatial position of the detection grid, and realizing three-dimensional expression of the detection data through a synthetic aperture focusing imaging three-dimensional data processing method, so as to form a high-quality lining internal detection result and identify lini |
