Stirring blade structure for large-diameter stirring pile construction drilling tool
The stirring blade structure for the large-diameter stirring pile construction drilling tool comprises a drill bit center rod, at least one stirring blade unit is arranged in the radial direction of the drill bit center rod, and each stirring blade unit is arranged in the axial direction of the drill bit center rod; the stirring blade unit comprises stirring blade assemblies which are distributed up and down in the axial direction of the drill bit center rod. The stirring blade assembly comprises stirring wing plates and flow guide plates, the flow guide plates are arranged on the upper plate surfaces and/or the lower plate surfaces of the stirring wing plates, the stirring wing plates are fixed to the drill bit center rod, and the number of the stirring wing plates is at least two, and the stirring wing plates are distributed at equal intervals in the radial direction of the drill bit center rod; through forced flow guide disturbance of the structure on a soil layer, the repeated cutting and stirring effect of the pile body in the horizontal direction can be improved, the pile body quality and construction efficiency of the stirring pile are effectively improved, the dosage of a curing agent is reduced, and meanwhile the stirring pile has the characteristics of self bending moment and moment balance and the like.
本发明涉及一种用于大直径搅拌桩施工钻具的搅拌叶片结构，包括钻头中心杆，钻头中心杆的径向上设有至少一组搅拌叶片单元，且每组搅拌叶片单元均沿钻头中心杆的轴向布置；搅拌叶片单元包括沿钻头中心杆轴向并呈上下分布的搅拌叶片组件；搅拌叶片组件包括搅拌翼板和导流板，导流板设置在搅拌翼板的上板面和/或下板面上，搅拌翼板固定在钻头中心杆上，且搅拌翼板至少设有两块并围绕钻头中心杆的径向呈等间距分布；本发明通过结构对土层的强制导流扰动，能够增加桩身水平方向上的反复切割搅拌效果，有效地提高搅拌桩桩身质量和施工工效、降低固化剂用量等特点，同时具有自身弯矩、力矩平衡等特点。
