At present, the pile drivers on the market mainly consist of the following components: drop hammer pile driver, steam hammer pile driver, diesel hammer pile driver, hydraulic hammer pile driver and screw pile driver. The spiral pile driver is a pile driving device which drives a drill rod drill bit to form a hole on an underground drilling machine through a power head. The screw pile driver can be divided into two parts: a pile frame and a drilling section.

In the spiral piling equipment in the prior art, in the process of drilling a hole into the ground by a drill bit, a dry soil layer has the problem of dust emission during drilling, so that the standard of environment-friendly construction cannot be met, and meanwhile, when the drill bit faces a soil layer with high hardness, the drill bit is greatly blocked deeply, so that the drilling efficiency is reduced; in addition, when the drilling part of the spiral piling equipment continuously drills deep, because an effective lubricating structure of the drilling part is not provided, when the drilling structure is deeply drilled into the soil layer and contacts with hard objects, the continuous drilling efficiency and the durability of the drill bit are reduced.
