临海抛石区嵌岩咬合桩的分层施工

Layered Construction of Rock-socketed Interlocking Piles in Coastal Riprap Area

针对深层含大块片石或抛石临海区域的桩基施工需求,在原有工程咬合桩施工工艺的基础上,通过对工艺、器具等进行研究、改进,结合临海实际工程地质的特殊性,总结了相应的施工技术。该技术操作方便、灵活多变,解决了临海抛石地区复杂地质条件下嵌岩咬合桩的施工难题,并在造价、环境保护、施工进度等方面具有一定优势,可以在以后类似的工程中进行推广应用。

According to the requirements of pile foundation construction in the deep area with large rubble or coastal riprap area,based on the construction technology of the original interlocking piles,the corresponding construction technology is summarized through the research and improvement of the technology and instruments,and in combination with the particularity of the actual engineering geology in the sea.The technology is easy to operate and flexible,which solves the construction problems of rock-socketed interlocking piles under complex geological conditions in coastal riprap area,and has certain advantages in cost,environmental protection,construction progress,etc.It can be popularized and applied in similar projects in the future.
