Grouting hole guiding device for loose fill stratum
The invention belongs to the technical field of grouting hole guiding, and discloses a grouting hole guiding device for a loose fill stratum. The problem that the hole guiding efficiency of a drilling machine in the loose fill stratum is low is solved. The grouting hole guiding device comprises an outer sleeve, a thread is formed in the inner wall of the outer sleeve, a rotating disc is in threaded connection to the outer sleeve, a through hole matched with the outer diameter of a steel floral tube is formed in the middle of the rotating disc, at least three clamping blocks used for clamping the steel floral tube are installed on the rotating disc, a connecting rod used for driving the clamping blocks to move is installed on the rotating disc, a first thrust bearing is connected to the upper end of the connecting rod, the periphery of the first thrust bearing is sleeved with a fixing disc, and a fastening part is arranged at the top of the fixing disc. According to the grouting hole guiding device, the steel floral tube achieves downward pressing spiral drilling, and the hole guiding efficiency of a grouting hole is improved; and meanwhile, the two processes of grouting hole guiding and steel floral tube pressing into the loose fill stratum are combined into one process, and the grouting reinforcement efficiency can be greatly improved.
本发明属于注浆引孔技术领域，公开了一种用于松散填土层的注浆孔引孔装置，为了解决钻机在松散填土层中存在着引孔效率低问题。本发明包括外套筒，所述外套筒的内壁开设有螺纹，所述外套筒上螺纹连接有旋转盘，所述旋转盘的中部开设有与钢花管的外径相互适配的通孔，所述旋转盘上安装有至少三个用于夹持钢花管的夹持块，所述旋转盘上安装有用于带动夹持块运动的连杆，所述连杆的上端连接有第一止推轴承，所述第一止推轴承的外围套设有固定盘，所述固定盘的顶部设置有紧固部。本发明钢花管实现下压螺旋钻进，提高注浆孔的引孔的效率；同时将注浆孔引孔与钢花管压入松散填土层两种工序为一种，能够大大提高注浆加固的效率。
