Rock breaking pile foundation construction method
The invention discloses a rock breaking pile foundation construction method, and relates to the technical field of pile foundation construction. The rock breaking pile foundation construction method comprises the steps that a plasma rock breaking device is adopted for rock breaking construction to obtain an initial pile foundation hole; wall trimming and hole cleaning are performed on the initialpile foundation hole by adopting a rotary drilling rig to obtain a final pile foundation hole; a reinforcement cage is placed into the final pile foundation hole through hoisting; and concrete is poured into the final pile foundation hole where the reinforcement cage is placed through hoisting. The pile foundation construction method is simple in process, easy to operate and not prone to accidents, through mutual cooperation of two rock breaking devices, the method can adapt to drilling of rock strata with different hardness, the rock breaking pile foundation construction efficiency is improved, and meanwhile the construction cost is reduced.
本发明公开了一种破岩桩基施工方法，涉及桩基础施工技术领域。破岩桩基施工方法包括：采用等离子体破岩装置破岩施工得到初始桩基孔；采用旋挖钻机对初始桩基孔进行刷壁和清孔后得到最终桩基孔；向最终桩基孔内吊放钢筋笼；向吊放好钢筋笼的最终桩基孔内灌注混凝土。上述桩基施工方法流程简单，易于操作，不易发生事故，且通过两种破岩装置的相互配合，可以适应不同硬度岩层的钻进，不仅提高了破岩桩基施工的效率，同时还降低了施工的成本。
