The invention provides a use of a pile-forming machine for dual-round-head piles. Soil outside six stirring heads, and in a left round head frame and a right round head frame is cut under the left-right mutual movement of cutter teeth I and cutter teeth II in the left round head frame and the cutter teeth I and cutter teeth II in the right round head frame; the cut soil is mixed with high pressure water; the mixture is stirred into mud; the mud flows through a hole; a hole body with a biconcave round head at the front end and a biconvex round head at the back end is formed during the downward pressing movement of a drill rod; a reinforcing cage is arranged in the hole body; concrete is poured to form a concrete dual-round-head pile. A plurality of the concrete dual-round-head piles can be in plug-in connection for combination in such a manner that the biconcave round head at the front end of one concrete dual-round-head pile sleeves the biconvex round head at the back end of an adjacent concrete dual-round-head pile; the combined structure is used for cutting off seepage of underground water in a foundation pit of a building foundation.
