Application of the Assembly of Large Prefabricated Pier Columns and Sleeve Grouting Connection Construction
An actual elevated bridge project is taken as a case to study the stability of large prefabricated pier column connection.The prefabricated pier column hoisting technology is adopted to accurately control the position and calibration of the pier column,and the C100 high-strength non-shrink cement grouting material is used with the sleeve grouting connection technology for casting,which ensures the construction quality of the assembling of large bridge prefabricated pier columns to the greatest extent.The results show that the grouting part is well sealed and densely filled with the water leakage rate of 0.00%.No bubbles are seen,and the surface flatness of each pier column falls within 3 mm,which achieves the ideal construction results.
