HZ/AZ组合钢板桩施工技术

Construction technology of HZ/AZ combined steel sheet piles

对广州港南沙港区粮食及通用码头工程水工结构工程(码头C段)HZ/AZ组合钢板桩沉桩施工工艺进行介绍。该工程对导向架和替打进行了合理的设计和改造,采用的是振动锤插桩、利用柴油锤复打的沉桩工艺。结果表明,全部HZ型和AZ型钢板桩都达到了设计高程,沉桩效果良好,该施工工艺可以供类似工程借鉴。

This paper introduces the technologies of driving HZ/AZ combined steel sheet piles in Nansha port area of Guangzhou port grain and general-purpose wharf. In this project, the guide frame was specially designed, and the equipments are reasonably transformed. Piles are first inserted by the vibrator, and then driven to the design depth by hammer. The results show that both HZ-shape pile and AZ-shape pile are driven to the design depth with good quality. The technology may serve as a reference for similar projects.
