| 中文摘要:根据温州港状元岙港区化工码头工程的地层条件和码头的特殊要求，其桩基础设计了嵌岩斜桩，斜度1∶5～1∶6。施工中应用冲击成桩施工工艺。通过自行设计的钢护筒导向架控制桩孔斜度、筒柱式空心锤冲击成孔、橄榄球式混凝土灌注导管灌注混凝土等针对性很强的施工措施，顺利圆满地完成了施工任务。通过桩基检测，桩基质量完全满足规范和设计要求。为类似工程的施工提供了宝贵的经验。 |

| Abstract:According to the ground conditions of the chemical wharf project in the Zhuangyuan’ao Port area of Wenzhou and special requirements of the wharf, slant rock-socketed piles with a slope of 1∶5～1∶6 were designed for the pile foundation. The construction job was successfully completed through taking very specific construction measures, such as the self-designed steel casing guide frame to control pile-hole inclination, percussion drilling with the cylindrical hollow hammer to sink the borehole, the rugby type tremie pipe to pour concrete, and so on. Pile-foundation inspection shows that the pile-foundation quality fully meets the specification. It provides valuable experiences for similar projects. |
