| 中文摘要: |
| 结合某跨海大桥桩基缺陷处理工程，介绍高压清水旋喷冲洗、气举反循环清渣、孔内静压注浆、高压旋喷注浆、孔口压浆相结合的方法在大直径灌注桩处理中的应用。采用上述方法处理后，经检测水泥固结体完整，与桩身混凝土、基岩胶结紧密。 |
| 英文摘要: |
| Combined with a defects treatment engineering of a sea-crossing bridge,this paper introduces application of high pressure jet cleaning,cutting removal by air-lift reverse circulation,static pressure grouting,high pressure jet grouting and orifice press grouting in defects treatment of large diameter cast-in-place piles. Test results show that the cement paste is complete and cemented closely with pile concrete and bedrock after treated. |
