Cement mixing pile drilling tool
The invention relates to a cement mixing pile drilling tool, and belongs to the field of civil construction equipment, the cement mixing pile drilling tool comprises a drill rod and a drill bit, the drill bit is fixedly connected to one end of the drill rod, the drill bit comprises a drill tip, a mixing rod and a spray pipe, the length direction of the mixing rod is perpendicular to the length direction of the drill rod, and a slurry feeding channel is formed in the drill rod; the spraying pipe is fixedly connected with the stirring rod, a soil breaking blade is arranged on the drill rod, an included angle is formed between the extending direction of the soil breaking blade and the vertical direction, and the extending direction of the soil breaking blade inclines towards the rotating direction of the drill bit. In the rotary drilling process of the drilling tool, the soil breaking tool bit impacts and crushes rock and soil below the drill bit, the resistance and damage effect of gravel structures and hard soil blocks in soil on the stirring rod are reduced, and the drilling smoothness of the drilling tool is improved.
本申请涉及一种水泥搅拌桩钻具，属于土建施工设备的领域，其包括钻杆和钻头，所述钻头固定连接于钻杆的一端，所述钻头包括钻尖、搅拌杆和喷管，所述搅拌杆的长度方向与钻杆的长度方向垂直，所述钻杆内开设有送浆通道，所述喷管与搅拌杆固定连接，所述钻杆上设有破土刀片，所述破土刀片的延伸方向与竖直方向形成夹角，所述破土刀片的延伸方向朝钻头转动的方向倾斜。本申请在钻具旋转钻进的过程中，破土刀头对钻头下方的岩土进行冲击和破碎，减小土质中碎石结构以及硬质土块对搅拌杆的阻力和损伤效果，提高钻具钻进的流畅程度。
