The invention belongs to the technical field of foundation piles, and particularly relates to a deep cement mixing pile pouring construction method which comprises the steps of field leveling, pile testing, drilling machine entering, cutting and sinking, lifting and guniting, re-mixing, cleaning and shifting and pile forming. Various parameters during construction are determined, verified and adjusted through the construction test pile, meanwhile, the automatic adjusting component with the proper adjusting capacity is selected, and the size of a drill bit spraying hole is adjusted at different depths through the automatic adjusting component during drilling construction, so that the overall slurry spraying distance is stable, and the construction efficiency is improved. Therefore, even distribution of slurry in the pile body is guaranteed, upper and lower basic box bodies of the pile diameter are guaranteed, the strength of the pile body is improved, and the bearing capacity of a foundation meets the design requirement.
本发明属于基桩技术领域，具体的说是一种深层水泥搅拌桩灌注施工方法，包括场地整平、试桩、钻机进场、切削下沉、提升喷浆、复搅、清洗移位和成桩；本发明通过施工试验桩来确定验证，调整施工时的各项参数，同时选取合适调节能力的自动调节部件，在钻进施工时通过自动调节部件在不同深度对钻头喷孔大小进行调节，使得浆液整体喷出距离稳定，进而保证浆液在桩体中的均匀分布以及保证桩径上下基本箱体，进而提高桩体的强度，进而使得地基承载能力满足设计需求。
