The invention discloses a large-diameter rock-socketed pedestal pile pedestal expanding quality control method, and belongs to the field of building pedestal pile detection. The control method comprises the following steps that a pedestal pile hole is drilled, the upper layer of the pedestal pile hole is set as a stepped hole surface, a middle positioning frame is erected on the stepped hole surface, a hole position plate is mounted on the middle positioning frame, a mounting hole is formed in the hole position plate, a mounting ring is arranged below the mounting hole, the mounting ring is fixedly connected with the middle positioning frame through connecting flexible parts, a measuring umbrella is mounted below the mounting hole, a sleeve pipe and a vertical pipe are erected in the mounting hole, the vertical pipe is mounted firstly, then the sleeve pipe is mounted, a measuring range is arranged at the top end of the vertical pipe through the measuring umbrella, the sleeve pipe is mounted outside the vertical pipe, and the outer diameter size of the sleeve pipe is matched with the inner diameter size of the mounting hole. The method aims at solving the problems that in the prior art, after the diameter of the bottom of the pedestal pile hole is expanded, the hole diameter can only be estimated through the extension time of an expanded bore drill bit or the bore diameter is manually measured at the bottom of the pedestal pile hole, efficiency is low, and danger exists.
本发明公开了一种大直径嵌岩扩底桩扩底质量控制方法，建筑扩底桩检测领域，包括钻设扩底桩桩孔，扩底桩桩孔上层设置为阶梯孔面，在阶梯孔面上架设中间定位架，在中间定位架上安装孔位板，孔位板内设置有安装孔，在安装孔下设置有安装环，安装环通过连接柔性件与中间定位架固定连接，安装下安装测量伞，在安装孔内架设套筒管和竖直管，先安装竖直管后安装套筒管，且依次通过测量伞，竖直管顶端设置有量程，将套筒管安装在竖直管安装外，套筒管的外径尺寸与安装孔的内径尺寸相适配；本发明针对现有技术中对扩底桩底部直径扩孔后，只能通过扩底钻头延展时间预估孔径或通过人为下扩底桩桩孔底部测量孔径，效率低下且存在危险。
