The invention discloses a prefabricated member semi-grouting sleeve connection structure, which comprises a barrel body, wherein a through groove is formed in the barrel body, a slurry feeding openingand a slurry discharging opening which penetrate through the through groove are arranged on an outer lateral wall of the barrel body, a threaded installation hole is formed at one end of the barrel body, a rubber sealing ring is arranged at the other end of the barrel body, a stirring part is arranged in the barrel body, the stirring part is in a hollow sleeve shape, a first fixed rod and a second fixed rod are arranged in the lateral direction of the stirring part, the first fixed rod extends out of the slurry feeding opening, the second fixed rod extends out of the slurry discharging opening, and the first fixed rod and the second fixed rod are used for driving the stirring part to rotate. As the stirring part is arranged in the semi-grouting sleeve, cement in the barrel body can be even by rotating the stirring part, and the barrel body can be fully filled with the cement; the first fixed rod or the second fixed rod serves as a driving part of the stirring part, and the first fixedrod and the second fixed rod extend out of the slurry feeding opening and the slurry discharging opening; thus, convenience is brought to operation when the first fixed rod and the second fixed rod are driven.
