Geological treatment method for pile foundation drilling influenced by karst underground water or underground river
The invention relates to the technical field of building pile foundation construction, in particular to a pile foundation drilling geological treatment method influenced by karst underground water or underground rivers. The invention provides a treatment method capable of guaranteeing rapid and effective pile forming of a percussion drill in a karst area by taking the influence of a single factor of karst underground water or underground river on pile foundation construction and combining the phenomena of grout runout and hole collapse generated in the drilling process of percussion drill equipment under the geological condition as analysis points. According to the exploration conditions of underground water and underground rivers, different slurry loss amounts, rates and hole wall collapse phenomena generated by karst characteristics encountered in the field pile foundation drilling process serve 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，具体涉及受岩溶地下水或地下暗河影响的桩基钻孔地质处理方法。本发明以桩基施工受岩溶地下水或地下暗河单一因素的影响，结合冲击钻设备在该地质条件下钻孔过程中产生的跑浆及塌孔现象为分析点，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，根据地下水和地下暗河的勘探情况，以现场桩基钻孔过程中遇到的岩溶特征产生的不同泥浆流失量、速率和孔壁坍塌现象为分析要点，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。
