Geological treatment method for pile foundation drilling influenced by karst fissures
The invention relates to the technical field of building pile foundation construction, in particular to a geological treatment method for pile foundation drilling affected by karst fissures. According to the geological treatment method, the influence of a single factor of karst fissures on pile foundation construction is combined with the phenomena of grout seepage, grout leakage and grout runout generated in the drilling process of percussion drill equipment under the geological condition as analysis points, and it can be guaranteed that a percussion drill rapidly and effectively forms a pile in the karst area. Generally, according to the diameter and the length of the pile foundation, a geological survey report is combined, different mud loss phenomena generated in the field pile foundation drilling process serve as analysis key points, a targeted treatment method is provided, and the drilling construction period and cost of the pile foundation in the karst fissure area 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裂隙影响的桩基钻孔地质处理方法。本发明以桩基施工受岩溶裂隙单一因素的影响，结合冲击钻设备在该地质条件下钻孔过程中产生的渗浆、漏浆、跑浆现象为分析点，提出一种可保障冲击钻在该类岩溶区域快速、有效成桩的地质处理方法。一般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泥浆流失现象为分析要点，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。
