Construction method of large-diameter super-long cast-in-place pile
The invention relates to a large-diameter super-long cast-in-place pile construction method, which relates to the technical field of cast-in-place pile construction technology, and comprises the following steps: a construction preparation step: leveling a construction site, and tamping and filling compactly; a step of embedding a steel pile casing: excavating and embedding the pile casing by adopting a machine; drilling: adopting static slurry to protect the wall in the drilling process; a hole-forming inspection step: when the drilling depth meets the design requirement, inspecting the hole position, the hole diameter, the hole depth, the gradient and the like; a hole cleaning step: cleaning the hole by adopting a slurry changing method; reinforcement cage manufacturing and mounting: pile foundation reinforcement cages are intensively manufactured in a reinforcement yard; the reinforcement cage is mounted by a truck crane; a guide pipe mounting step: hoisting the guide pipe into the hole; secondary hole cleaning, wherein secondary hole cleaning is conducted through the guide pipe; an underwater concrete pouring step, wherein underwater concrete pouring is continuously carried out; and the guide pipe and the steel casing are pulled out, specifically, after underwater concrete pouring is completed, the guide pipe and the steel casing are pulled out slowly through a crane. The cast-in-place pile has the effect of solving the problem that the construction difficulty of the cast-in-place pile is large.
本申请涉及大直径超长灌注桩施工方法，涉及灌注桩施工技术的技术领域，其包括以下步骤：施工准备步骤：平整施工场地，并夯填密实；钢护筒埋设步骤：采用机械开挖埋设护筒；钻孔步骤：钻进过程中采用静态泥浆护壁；成孔检查步骤：当钻孔深度达到设计要求时，对孔位、孔径、孔深和倾斜度等进行检查；清孔步骤：采用换浆法进行清孔；钢筋笼制作安装步骤：桩基钢筋笼在钢筋场中集中制作；钢筋笼安装采用汽车吊；导管安装步骤：导管吊装入孔；二次清孔步骤：利用导管进行二次清孔；灌注水下混凝土步骤：水下混凝土灌注连续进行；拔除导管及钢护筒步骤：水下混凝土灌注完毕，通过吊车慢速拔出。本申请具有改善灌注桩施工时难度大的问题的效果。
