深厚高含水量超软土反循环钻孔灌注桩施工技术研究

Study on Construction Technology of Reverse Circulation Bored Pile with Super High Water Content and Super Soft Soil

结合温州市域铁路S1线工程,阐述了深厚高含水量超软土反循环钻孔灌注桩施工技术,重点介绍了深厚高含水量超软土反循环钻孔灌注桩施工准备、施工工艺流程、质量保证措施。实践证明,该技术适用于土质松散、风积砂的温州市域地区,可有效增强工后地基承载能,减小不均匀沉降,具有加固效果显著、施工方便、缩短工期、节省费用等优点。可为类似工程提供借鉴和参考。

In this paper, the construction technology of anti - circulation bored pile with deep and high water content is introduced in this paper. The construction and construction process of reverse - circulation bored pile with deep and high water content are introduced. Quality assurance measures. I t is proved that the technology is suitable for the soft soil area and the area of Wenzhou area, which can effectively enhance the bearing capacity of the foundation after work and reduce the unevensettlement. It has the advantages of strong reinforcement effect, convenient construction, shortening the construction period and saving the cost. Can provide reference and reference for similar projects.
