旋挖钻进工艺在钻孔灌注桩后压浆工程中的应用

Application of Rotary Drilling in Post Pressure Grouting of Bored Grouting Pile

摘要:

针对武汉东湖一号钻孔灌注桩后压浆工程地质条件复杂，铁渣层、卵石层厚的特点，经过多种施工方案分析比较，采用旋挖钻进工艺，优化泥浆配制，满足了工程质量和进度要求。对旋挖钻进施工工艺、技术措施进行了总结，可供同类工程参考。

Abstract:

The paper presents a post pressure grouting construction case in Wuhan. According to the complicated geological conditions with thick slag and pebble layers, by the analysis and comparison of several construction schemes, rotary drilling was selected with optimized high quality mud to satisfy the requirements of engineering quality and construction progress. The construction technologies and the technical measures of rotary drilling were summed up to be reference to the similar projects.
