In recent years, steel shell concrete structures have become more and more widely used in construction projects, and steel shell concrete voids are an important reason affecting their structural quality. Therefore, steel shell concrete void detection is of great significance to ensure the engineering quality of steel shell concrete structures. On the basis of elaborating the principle of shock elastic wave detection of concrete voids in steel shells, this standard describes the detection equipment, detection steps, collection and analysis of detection data, detection conclusions, and preparation of detection reports involved in using this method to detect voids. stipulated.
