Three-dimensional rotary-cut mixing pile
The invention discloses a three-dimensional rotary-cut mixing pile and belongs to the technical field of soft foundation treatment construction. A bevel gear is arranged in a stirring drill bit and meshed with a bevel gear at one end of a stirring shaft. The vertical stirring drill bit has the beneficial effects that the core rod in the stirring drill bit is meshed with the horizontal stirring shaft with the bevel gear through the bevel gear, so that the stirring blades on the stirring shaft are driven to rotate in the vertical direction, and the vertical crossed stirring function is realized under the combined action of horizontal stirring of the stirring blades on the stirring drill bit; in addition, the gas pipe attached in the drill rod pumps high-pressure gas into the stirring soil body, the gas explosion effect is achieved in the stirring soil body, and the stirring effect on the soft foundation soil body is further enhanced.
一种立体旋切搅拌桩，属于软基处理施工技术领域。它的搅拌钻头内设有锥形齿轮，与搅拌轴的一端锥形齿轮啮合。本发明的有益效果是：搅拌钻头中的芯杆通过锥形齿轮与带有锥形齿轮的水平搅拌轴啮合，从而带动搅拌轴上的搅拌叶片做竖直方向转动，与搅拌钻头上搅拌叶片的水平搅拌共同作用，实现立体交叉的搅拌功能，再加上钻杆中所附气管向搅拌土体中泵入高压气体，在搅拌土体中起到气爆作用，进一步增强对软基土体的搅拌作用。
