The invention discloses a method for fixing an underground corrugated pipe. The method comprises the steps that S1. a plurality of fixing elements (2) are arranged along the axial direction of a corrugated pipe (1) at intervals and are mounted at the position of a trough (3) of the corrugated pipe (1); S2. the corrugated pipe (1) provided with the fixing elements (2) descends in a shaft; and S3. in the expansion process of the corrugated pipe (1), the fixing elements (2) are inserted into a well wall due to the wall of the corrugated pipe (1) for a certain depth. The method provided by the invention has the beneficial effects that the corrugated pipe can be fixed at the desired position in a drilling process, a well repairing process and other operation processes; the fixing effect is good; and the target stratum can be effectively sealed. The method has the advantages that the realization is easy, the reliability is high and the construction convenient; the fixing elements mounted in the trough in the transp
