Single-shaft stirring pile construction equipment with cutting stirring frame
The invention provides single-shaft stirring pile construction equipment with a cutting stirring frame, which comprises a pile frame, a drill rod arranged on the pile frame, drill rod blades arranged at the lower part of the drill rod, the stirring frame arranged on the drill rod, stirring blades arranged on the stirring frame, the stirring frame connected with the drill rod through a rotatable shaft sleeve, and the drill rod blades are of a multi-layer structure. A stirring blade layer is arranged between every two adjacent drill rod blade layers, at least one layer of beveled drill rod blades is arranged on the drill rod, and a layer of beveled stirring blades is also arranged at the corresponding position of the stirring frame. The beveled drill rod blades on the drill rod and the beveled stirring blades on the stirring frame form a beveled structure on the corresponding stirring plane. The beveled stirring blade and the drill rod blade move relatively to generate a beveled cutting effect, so that the undisturbed soil is crushed into fine particles to be fully mixed with the curing agent; and the strength and the water stopping effect of the mixing pile are greatly enhanced.
本发明提供一种带有切割搅拌架的单轴搅拌桩施工设备，包括桩架，桩架上设置有钻杆，钻杆下部设有钻杆叶片，钻杆上设置有搅拌架，搅拌架上设置有搅拌叶片，搅拌架通过可旋转轴套连接钻杆，钻杆叶片为多层结构，相邻钻杆叶片层之间设置有搅拌叶片层，钻杆上设置有至少一层对切钻杆叶片，所述搅拌架上对应位置处也设置有一层对切搅拌叶片；钻杆上的对切钻杆叶片与搅拌架上的对切搅拌叶片在对应搅拌平面上形成对切结构。对切的搅拌叶片与钻杆叶片相对运动，产生对切的切削作用，将原状土搅碎成细颗粒与固化剂充分混合；大大增强了搅拌桩的强度和止水效果。
