Soil removing device for CFG pile

The utility model belongs to the technical field of CFG pile construction, and particularly relates to a CFG pile soil removing device. Through the arrangement of the conveying mechanism and the soil collecting cylinder, the drilling muck is conveyed out of a site to be stacked in a centralized mode, the number of the drilling muck stacked around a drilled hole is effectively reduced, the construction procedure is optimized, and it is avoided that soil between piles is cleaned in the later period. And meanwhile, the quantity of drilling residue soil falling into the mixture from the drill hole is greatly reduced, the mixture is effectively prevented from being polluted, and the integrity of a pile foundation is greatly improved. The pile foundation pile-forming quality is further improved, the service life of roadbed engineering is prolonged, and engineering safety is guaranteed. Drilling residue soil generated during work of the spiral drilling machine is scraped through the soil scraping mechanism and colle
