详细介绍了该准φ2500mm桩基础桩身段因爆破原因发生裂隙后采用新型的清洗+注浆组合补强加固技术,合理选用次纳米级超细水泥基高性能灌浆材料,取得了较理想的加固效果,为今后同类型的桩基缺陷补强加固工程提供参考。
This paper introduces in detail the new cleaning + grouting combination reinforcing and reinforcing technology for the piles of quasi-φ2500mm pile foundations due to blasting, reasonably selects sub-nanometer ultrafine cement-based high performance grouting material and achieves better reinforcing effect , For the future of the same type of pile foundation defect reinforcement reinforcement project to provide a reference.
