扬溧高速新老路基拼接缝注浆首件告捷

Core Insights - The YLK-1 section of the Yangli Expressway expansion project has completed the first construction of the new and old roadbed joint grouting, marking a new phase in quality control for roadbed connections [1] - The grouting was executed strictly according to the grouting plan, with a maximum single hole grouting amount of 70 kilograms of cement and an average grouting amount meeting the standard of 50 kilograms of cement per hole [1] - The treatment of the new and old roadbed joints is a key technology in preventing uneven settlement in highway reconstruction projects, and the first grouting construction has effectively addressed potential risks due to differences in mechanical properties of the materials used [1] Technical Details - The project team optimized parameters such as hole spacing, hole depth, and grouting volume to enhance the integrity and durability of the entire roadbed [1] - The results of the grouting ensure the density and stability of the joint area while reinforcing the structural resistance to deformation of the expanded roadbed [1] - The project team will use the data from this construction to improve standardized processes, ensuring that the quality of the entire roadbed connection is controllable and traceable [1] Future Plans - The project team will continue to strengthen technical research and process control to create a high-quality engineering project [1]
