| 中文摘要: |
| The transverse,longitudinal beams and panels of high-pile wharf are gradually being designed and constructed in assembled structure.However,the pile core and pile cap structure in the water level fluctuation area are still mainly cast-in-place,which has a great impact on the overall construction period,quality and safety of the project.The bearing capacity and installation process of the prefabricated integrated pile core cap are studied by model experiment.The results show that the bearing capacity of the prefabricated pile core and cap structure mainly depends on the bonding performance between the grouting material and the steel pipe interface,and the average bonding strength of the new structure is higher than that of the traditional cast-in-place concrete and steel pipe bonding strength and its corresponding standard values,indicating good bearing performance.The developed airbag sealing device at pile bottom can meet the requirements of bearing and sealing performance,and the slurry has good fluidity during the embedded grouting process.The structure and installation process of prefabricated pile core and pile cap have good application effects in engineering projects. |
