浅谈大直径旋挖灌注桩成孔工艺及常见问题的处理

Discuss the Pore Forming Process Technology and Frequently Questions of Large Diameter Rotary Drilling Filling Piles

旋挖钻桩基础施工在珠三角地区高层建筑应用起步较早,具有高环保性和施工效率的特点。本文就佛山市世博商业中心工程旋挖钻孔桩基础施工经验,对旋挖钻孔桩成孔工艺、常见问题处理等相关内容进行总结,以供同类高层建筑中采用旋挖灌注桩施工作参考。

The application of rotary dril ing bored pile found-ation construction started earlier in the Pearl River delta region high-rise buildings, with the characteristics of high environme-ntal and construction efficiency. In this article, the author bases on the rotary dril ing bored pile foundation construction expe-rience in the engineering of Foshan City Expo business center, and summaries the pore-forming process and frequently asked questions treatment of rotary dril ing bored piles to provide re-ferences for similar high-rise building used rotary dril ing bored pile.
