搅拌植入桩端后注浆UHC管桩试验研究

Experimental Study on UHC Pipe Piles Implanted by Mixing and Post-grouting

介绍了搅拌植入桩端后注浆预制桩技术的工艺原理和施工流程,结合工程案例开展搅拌植入桩端后注浆预制桩的承载性能试验。试验结果表明,搅拌植入桩端后注浆UHC(超高强)管桩施工工艺简单、承载效果好、工程造价低且环境友好,具有良好的推广价值。

This paper introduces the process principle and construction process of post-grouting precast pile with embedded mixing pile tip,and carries out the bearing capacity test of post-grouting precast pile with embedded mixing pile tip combined with engineering cases.The test results show that the construction technology of post-grouting UHC pipe pile is simple,the bearing effect is good,the project cost is low and the environment is friendly,so it has good promotion value.
