Long spiral drilling and pouring construction device
The invention relates to a long spiral drilling and pouring construction device. Comprising a work frame, a spiral drill bit arranged on the work frame and a guide sleeve arranged on the spiral drill bit in a sleeving mode. The concrete conveying pump is connected with the circulating pipeline in the spiral drill bit through a connecting pipeline and used for pumping concrete into the circulating pipeline after the spiral drill bit drills to the preset drilling elevation and stops drilling, so that when the spiral drill bit after drilling stopping is lifted upwards, the concrete is poured to the preset pile top elevation through the circulating pipeline; the mounting seat is arranged on the guide sleeve; the scraper blade is horizontally arranged on the mounting seat, the scraper blade moves on the mounting seat in the horizontal direction, and the height of the scraper blade is equal to the screw pitch of the spiral drill bit, so that when the spiral drill bit is lifted upwards, the scraper blade can be inserted into a spiral gap in the spiral drill bit to clean cohesive soil on the spiral drill bit. According to the device, the cohesive soil on the spiral drill bit can be cleaned.
本申请是关于一种长螺旋钻孔灌注施工装置。包括：钻孔灌注桩机，包括工作架、设置在工作架上的螺旋钻头和套设在螺旋钻头上的导向套；混凝土输送泵，与螺旋钻头内的流通管道之间通过连接管道连接，用于当螺旋钻头钻孔至预设钻孔标高并停钻后，向流通管道泵入混凝土，以使将停钻后的螺旋钻头向上提时，流通管道将混凝土灌注至预设桩顶标高；安装座，设置在导向套上；刮板，水平设置在安装座上，刮板在安装座上沿水平方向移动，刮板的高度与螺旋钻头的螺距相等，以使当将螺旋钻头向上提时，刮板能够插入螺旋钻头上的螺旋间隙，以对螺旋钻头上的黏性土壤进行清理。本申请可以实现对螺旋钻头上的黏性土壤进行清理。
