Bidirectional stirring drill bit with front-arranged inner drill rod for stirring drilling
The invention discloses a bidirectional stirring drill bit with a front inner drill rod for stirring drilling, which belongs to the field of pile foundation construction equipment and comprises an inner mandrel, an outer frame, a sealing sleeve, an outer stirring blade, an inner stirring blade, a front stirring blade, a drill tip, an upper guniting port and a lower guniting port. The outer stirring blades and the inner stirring blades are distributed alternately, the upper guniting opening is formed in the joint of the uppermost inner stirring blade and the inner core shaft and located on the back-to-soil side of the inner stirring blade, the lower guniting opening is formed in the joint of the front stirring blade and the inner core shaft and located on the back-to-soil side of the front stirring blade, and the front stirring blade is connected with the inner core shaft through welding. Drill teeth are arranged on the front stirring blade, and the lower end of the inner core shaft is connected with the drill tip in a welded mode. By arranging the upper guniting opening and the lower guniting opening, only the lower guniting opening works in the downward drilling process, only the upper guniting opening works in the lifting drilling process, and the mixing uniformity of a curing material and soil is guaranteed in the construction process.
本发明公开了一种内钻杆前置搅拌钻进的双向搅拌钻头，属于桩基施工设备领域，包括内芯轴、外框架、密封套、外搅拌叶片、内搅拌叶片、前置搅拌叶片、钻尖、上喷浆口、下喷浆口；外搅拌叶片与内搅拌叶片交替分布，上喷浆口设置在最上层内搅拌叶片与内芯轴交接处且在内搅拌叶片背土侧，下喷浆口设置在前置搅拌叶片与内芯轴交接处且在前置搅拌叶片背土侧，前置搅拌叶片通过焊接与内芯轴连接，前置搅拌叶片上设置有钻齿，内芯轴的下端与钻尖焊接连接。本发明通过设置上下两个喷浆口，下钻仅下部喷浆口工作，提钻仅上部喷浆口工作，施工过程中保证了固化材料和土的混合均匀性。
