The invention discloses a process for reserving a groove for post-pipe-burying of a cast-in-place concrete wall. The process comprises the steps that (1) a semicircular steel pipe with a certain length is cut firstly, then a semicircular steel pipe mold is manufactured in a sectioned mode, and a thread screw is welded to the back face of the semicircular steel pipe mold; (2) after a reinforcementskeleton of a concrete wall body is bound, a wall formwork on the other side is erected temporarily, a sleeve sleeves the thread screw, the thread screw and the sleeve penetrate through the wall bodyand then penetrate through the formwork, a spacer and a nut are fixed to the reinforcement skeleton of the concrete wall body and the wall formwork on the other side, a semicircular steel pipe mold opening is adjusted to be parallel to the wall surface, a formwork on the side, wall formwork vertical purlines and wall formwork transverse purlines are mounted, and the formworks on the two sides arefixed through wall-penetrating bolts, spacers I and fastening nuts; and (3) after wall body concrete is cast to the strength, the wall body formworks are dismantled firstly, then the semicircular steel pipe mold is dismantled, and thus the reserved groove is formed. The quality of the reserved groove in the concrete wall surface is ensured, the mounting requirements of a buried pipeline are met, the overall perception effect of the wall is ensured, the labor intensity is reduced, and meanwhile, the construction period is shortened.
