Abstract

The invention discloses a drilling and stirring punch, which comprises a first driving assembly, a horizontal excitation assembly, a second driving assembly and a drilling and stirring assembly which are sequentially connected, wherein the first driving assembly is used for driving the horizontal excitation assembly to generate horizontal excitation force, and the second driving assembly is used for driving the drilling and stirring assembly to perform cutting and stirring operation. The drilling and stirring punch is provided with two operation modes, namely a horizontal vibration operation mode generated by a horizontal vibration assembly and a drilling and stirring guiding and hole forming operation mode generated by a drilling and stirring assembly. When the hole is formed, the two operation modes of horizontal excitation and drilling and stirring guiding hole forming are combined, so that the penetrating power is high and the hole forming efficiency is high. When the pore-forming is completed and the pile-forming stage is carried out by filling the filler section by section, the horizontal vibration excitation mode can be adopted independently, the high-efficiency vibration extrusion of the dense pile body is facilitated, and the formed pile body is better in quality. Therefore, different modes can be selected for construction according to the construction step, and the flexible and flexible adaptability is high.
