Pile forming construction method for complex geological pile foundation
The invention relates to the technical field of complex geological pile foundation construction, and particularly discloses a pile forming construction method for a complex geological pile foundation. When the content of karst caves and cracks reaches 70% or above, the karst caves and the cracks are injected to be compact through karst grouting, and then pile foundation drilling is conducted; and when the content of the karst caves and the cracks of the pile foundation reaches 30% or below, pile foundation drilling is conducted through a follow-up steel casing. According to the pile forming construction method for the complex geological pile foundation, the influence of complex geology on pile foundation construction is effectively avoided, the construction quality is effectively improved, construction is conducted according to the different occupied amounts of the karst caves and the cracks in each pile foundation through different methods, and the construction cost is greatly reduced.
本发明涉及复杂地质桩基施工技术领域，具体公开了一种复杂地质桩基成桩施工方法，当溶洞和裂隙达到70％以上时，首先采用岩溶注浆将溶洞和裂隙注密实，然后进行桩基钻孔；当桩基的溶洞和裂隙达到30％以下时，采用跟进钢护筒进行桩基钻孔。本发明将有效的避免复杂地质对于桩基施工的影响，有效的提高了施工质量，采用不同的方法对于每根桩基中溶洞和裂隙占用量的不同分别施工，将大大节约施工成本。
