Inverted-cup-shaped mixing pile, mixing pile drill bit and mixing pile construction method
The invention discloses an inverted-cup-shaped mixing pile, a mixing pile drill bit and a mixing pile construction method.The inverted-cup-shaped mixing pile is of a concentric cement mixing pile structure with the solid top and the hollow bottom, and the corresponding mixing pile drill bit comprises a drill bit body which is in a circular tube shape; the fixed blade is fixedly mounted on the outer side of the drill bit body; the movable blades are hinged to the inner side of the drill bit body through one-way hinges, the drill bit body rotates forwards to enable the movable blades to contract, and the drill bit body rotates reversely to enable the movable blades to extend; the grouting pipe is embedded in the drill bit body, and the end of the grouting pipe is exposed out of the end of the drill bit body. A tubular pile body can be constructed through the tubular drill bit body, and the internal movable blades can be controlled to contract or stretch by changing the rotating direction of the drill bit body, so that transition between a solid pile and a hollow pile is achieved, and one-time pile forming is achieved. The invention relates to the technical field of civil engineering.
本发明公开了一种倒杯型搅拌桩，一种搅拌桩钻头以及搅拌桩施工方法，倒杯型搅拌桩为顶部实心而底部空心的同心水泥搅拌桩结构，相对应的搅拌桩钻头包括钻头本体，其呈圆管状；固定叶片，其固定安装在钻头本体的外侧；活动叶片，其通过单向铰链铰接在钻头本体的内侧，钻头本体正向旋转能够使活动叶片收缩，钻头本体反向旋转能够使活动叶片伸展；注浆管，其内嵌在钻头本体中，注浆管的端部从钻头本体的端部露出。本发明通过管状的钻头本体能够施工管状桩体，而且通过改变钻头本体的旋转方向，可以控制内部的活动叶片进行收缩或伸展，从而实现实心桩和空心桩的过渡，一次成桩。本发明涉及土木工程技术领域。
