Geological treatment method for pile foundation drilling influenced by karst fault fracture zone
The invention relates to the technical field of building pile foundation construction, in particular to a pile foundation drilling geological treatment method influenced by a karst fault fracture zone. According to the treatment method, pile foundation construction is influenced by a single factor of a karst fault fracture zone, and the phenomena of grout runout and large-area hole collapse generated in the drilling process of percussion drill equipment under the geological condition are combined as analysis points, so that the treatment method capable of guaranteeing rapid and effective pile forming of the percussion drill in the karst area is provided; and in combination with a geological survey report, the targeted treatment method is provided by taking different grout runout and large-area hole collapse phenomena generated in the field pile foundation drilling process as analysis key points, so that the drilling construction period and cost of the karst fissure area pile foundation are 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断层破碎带影响的桩基钻孔地质处理方法。本发明以桩基施工受岩溶断层破碎带单一因素影响，结合冲击钻设备在该地质条件下钻孔过程中产生的跑浆、大面积塌孔现象为分析点，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产生的不同跑浆、大面积塌孔现象为分析要点，提出针对性的处理方法，降低岩溶裂隙区桩基的钻孔施工周期和成本。
