Research on 3D Laser Scanning for Enhancing Production Quality Control of Concrete Prefabricated Beams

Based on the Hangzhou-Ningbo Expressway project, with the aim of addressing the drawbacks pertaining to challenging quality control, lengthy production duration, and low cost-effectiveness in the process of manufacturing concrete precast beams, this study employs three-dimensional laser scanning technology as a means of data acquisition in monitoring the quality of concrete precast beam spacing, size, and flatness within precast beam yards. By means of statistical analysis on the collected deviation data, various deviations in key indices of prefabricated components are identified, and the underlying causes for installation discrepancies are summarized. The test results convincingly demonstrate that the utilization of three-dimensional laser scanning technology can significantly enhance both efficiency and accuracy in quality inspections of finalized precast beams. Furthermore, this technique holds tremendous potential for application in quality control measures concerning concrete precast beams, thereby offering valuable technical support towards advancing the development of prefabricated concrete beams.
