Geological treatment method for pile foundation drilling influenced by karst cave
The invention relates to the technical field of building pile foundation construction, in particular to a pile foundation drilling geological treatment method affected by karst caves. According to the treatment method, under the influence of single factors of karst caves in karst types on pile foundation construction, the phenomena of drill jamming, slurry leakage and hole collapse generated in the drilling process of percussion drill equipment under the geological conditions are combined as analysis points, and the treatment method capable of guaranteeing rapid and effective pile forming of the percussion drill in the karst areas can be provided; in combination with a geological survey report, by taking different drill jamming, slurry leakage and hole collapse phenomena generated by karst characteristics encountered in the field pile foundation drilling process as analysis key points, a targeted treatment method is provided, pile foundation drilling is rapidly completed, the karst treatment period is shortened, and the karst treatment cost is reduced.
本发明涉及建筑桩基础施工技术领域，具体涉及一种受岩溶溶洞影响的桩基钻孔地质处理方法。本发明以桩基施工受岩溶类型中的岩溶溶洞单一因素影响下，结合冲击钻设备在该地质条件下钻孔过程中产生的卡钻、漏浆、塌孔现象为分析点，提出一种可保障冲击钻在该类岩溶区快速、有效成桩的处理方法，根据桩基直径和桩长，结合地质勘察报告，以现场桩基钻孔过程中遇到的岩溶特征产生的不同卡钻、漏浆、塌孔现象为分析要点，提出针对性的处理方法，快速完成桩基钻孔和降低岩溶处理的周期和成本。
