The invention belongs to the field of building construction tools, and particularly relates to a sleeve grouting warehouse sealing tool for a fabricated shear wall. The sleeve grouting warehouse sealing tool comprises an arc-groove-type tile-plate-shaped warehouse sealing arc plate and a handle convenient to hold in hand. The handle is in an inverted U shape, the two end portions of the handle are fixedly welded to the inner side cambered surface of the warehouse sealing arc plate, a plumb line symmetrical plane is made along the axis of the warehouse sealing arc plate to subdivide the warehouse sealing arc plate in a half-and-half mode, and the handle is located on the plumb line symmetrical plane. The sleeve grouting warehouse sealing tool for the fabricated shear wall has the advantages of being firm and reliable in construction, convenient in operation and low in manufacturing cost, further has good controllability and can ensure that the overall waterproof quality of a wall can meet the needs of design.
