摘要
海南洋浦跨海大桥主墩采用37Φ2.2~2.5m变截面钻孔灌注桩,桩长86-110m。本文主要介绍针对海上复杂地质条件下超长钻孔灌注桩旋挖钻机成孔施工工艺、施工工艺和质量控制措施。
The main piers of Hainan Yangpu Cross-sea Bridge are bored piles,86-110cm long,with the variable cross-section of 37Φ2.2-2.5m.This thesis focuses on the construction technology and quality control measures of drilling holes on overlong bored piles by rotary drilling rigs under complicated maritime geological conditions.
