Guide drilling device for cast-in-situ bored pile in complex geology and construction method of guide drilling device
The invention discloses a complex geological cast-in-situ bored pile guide drilling device and a construction method thereof, and belongs to the field of bridge construction.The device comprises a base platen, a grounding piece is arranged at the outward end of an abutting rod, a pressure steel ball is arranged at the inward end of the abutting rod, and two pressure sliding blocks are installed on a pressing guide rail in a sliding mode; the two sides of the pressure sliding block are provided with slope blocks attached to the pressure steel ball, and the pressure sliding block is connected to the pressure assembly. When the device is used, a cutting motor drives an extending belt and a driven rotary disc to rotate through a driving disc, a three-dimensional pipe rotates along with the driven rotary disc, and then a penetrating square rod in the three-dimensional pipe and a cutting disc at the bottom end of the penetrating square rod can be pressed on the ground to conduct rotary trepanning operation, and meanwhile a telescopic air cylinder drives a notch frame to ascend and descend; the notch frame drives the lifting disc at the top end of the inserting square rod to descend by a small distance, the descending distance of the inserting square rod is the punching depth of the cutting disc, and the efficient punching effect is achieved.
本发明公开了一种复杂地质钻孔灌注桩导向钻孔装置及其施工方法，属于桥梁施工领域，该装置包括基台板，抵触杆朝外的端头设置有接地片，且抵触杆朝内的端头设置有压力钢球，压合导轨上滑动安装有两个压力滑块，压力滑块的两侧设置有贴合在压力钢球上的斜面块，压力滑块连接到压力组件上。本发明在使用的时候，切割电机通过驱动装盘带动延伸皮带和从动转盘旋转，立体管随着从动转盘一起旋转，进而立体管内部的穿插方杆和其底端的切割盘会压合在地面上进行旋转开孔作业，与此同时的伸缩气缸带动槽口架升降，槽口架驱动穿插方杆顶端的升降盘下降一小段距离，穿插方杆下降的这段距离就是切割盘的打孔深度，实现了高效开孔的效果。
