An on-site cleaning method of contaminated soil using pipe propulsion is provided to increase the cleaning efficiency of contaminated soil, substantially reduce a period required for cleaning the contaminated soil, and prevent expansion of the contaminated area due to outflow of the cleaning solution by remarkably improving the recovery ratio of a cleaning solution injected into a contaminated area. In an on-site treatment method for cleaning of contaminated soil by injecting a cleaning solution into the ground and recovering the cleaning solution, an on-site cleaning method of contaminated soil using pipe propulsion comprises: a base constructing step(S10) of vertically excavating the ground near the contaminated soil and temporarily constructing an underground wall to form an excavated base(50); an upper pipe propulsion step(S20) of pressing a casing(60) from the constructed excavated base toward the contaminated soil and digging earth and sand in the casing at the same time; an upper penetration object forming step(S30) of simultaneously filling a permeable material into the casing penetrated through the upper pipe propulsion step and drawing out the casing to an inner side of the excavated base to form an upper penetration object(30); a lower pipe propulsion step(S40) of pressing the casing from the excavated base to a lower part of the contaminated soil-distributed ground and digging earth and sand in the casing at the same time in such a way that a predetermined slope is formed from a front end of the casing to the excavated base; and a lower penetration object forming step(S50) of simultaneously filling a permeable material into the casing penetrated through the lower pipe propulsion step and drawing out the casing to the inner side of the excavated base to form a lower penetration object(40). Further, the on-site cleaning method additionally comprises a injection well installing step of installing the injection well at an upper part of the upper penetration object.
