Stirring drilling tool
The invention provides a stirring drilling tool, and belongs to the field of building machinery. The column array type underground diaphragm wall is widely applied to building foundation pit supporting engineering in China, the column array type underground diaphragm wall is formed in the mode that a set of drill rods are driven by a special multi-shaft drilling machine, cement grout can be injected into loosened soil through the ends of drill bits in the drilling process, and a cement soil wall body is constructed. However, in the prior art, drill holes formed during rotation of a drill rod are circular, and the effective width of a groove body formed by a plurality of continuous drill holes is smaller than the diameter of the drill holes, so that the effective thickness of a constructed wall body is smaller than the design requirement. The invention provides a stirring drilling tool which comprises a power source, a transmission device, a drill rod set and a cutting device, the drill rod set comprises a plurality of drill rods, protruding sections are arranged on the drill rods, the cutting device is rotationally connected to the protruding sections of the drill rods through a buffer device, and when the drill rods rotate, the protruding sections form a cam mechanism to drive the cutting device to do reciprocating motion to cut and widen a groove body. The effective thickness of the continuous wall is increased.
本发明提供一种搅拌钻具，属于建筑机械领域。柱列式地下连续墙在我国建筑基坑支护工程中应用广泛，柱列式地下连续墙是由专用的多轴钻机驱动一组钻杆，钻进过程中钻头端部可以向搅松的土壤中注入水泥浆液，构筑成一段水泥土墙体。但是现有技术中，钻杆回转时形成的钻孔为圆形，多个连续钻孔形成的槽体有效宽度小于钻孔直径，致使构筑成的墙体有效厚度小于设计要求。本发明提供一种搅拌钻具，包括动力源、传动装置、钻杆组和切割装置，钻杆组包括多根钻杆，钻杆上设置有凸出段，切割装置通过缓冲装置转动连接在钻杆的凸出段，钻杆转动时，凸出段形成凸轮机构带动所述切割装置往复运动，切平扩宽槽体，增加连续墙有效厚度。
