Large-diameter deep mixing pile drilling tool and mixing equipment
The invention relates to the technical field of underground construction mechanical equipment, in particular to a large-diameter deep mixing pile drilling tool and mixing equipment which comprise a top connector, a main rod, a first mixing blade, a second mixing blade, a free blade, a tunneling blade and a spiral drill tip. The top connector is fixedly connected to the top of the main rod. A material conveying channel is arranged in the main rod; the first stirring blade and the second stirring blade are arranged on the main rod in the axial direction of the main rod at intervals, the free blade is movably connected to the main rod, and the tunneling blade is arranged on the lower portion of the drilling tool. A slurry conveying pipe communicated with the material conveying channel is arranged at the bottom of the tunneling blade; guniting holes are formed in the tunneling blades; the spiral drill tip is fixedly connected to the bottom of the main rod. The stirring device has the advantages that the solidified soil body between the stirring blades is prevented from huddling and pasting, the stirring is more uniform, and the construction quality of the deep stirring pile is improved.
本发明涉及地下施工机械设备技术领域，一种大直径深层搅拌桩钻具和搅拌设备，包括顶部接头、主杆、第一搅拌叶片、第二搅拌叶片、自由叶片、掘进叶片和螺旋钻尖；顶部接头固定连接在主杆的顶部；主杆内设有材料输送通道；第一搅拌叶片和第二搅拌叶片沿主杆的轴向间隔设置在主杆上，自由叶片活动连接在主杆上，掘进叶片设置在钻具下部；掘进叶片底部设置有与材料输送通道相连通的输浆管；掘进叶片上设置有喷浆孔；螺旋钻尖固定连接在主杆底部。本发明的优点是防止了搅拌叶片之间的固化土体发生抱团糊钻，也使搅拌更加均匀，提高深层搅拌桩的施工质量。
