The invention provides a mounting technology of a box body on the masonry wall surface. The mounting technology comprises the following steps that square steel is determined; a box body auxiliary frame is manufactured; treatment of reserved holes is conducted; the box body bottom elevation is determined; previous preparation for fixing the box body auxiliary frame is conducted; hole punching is conducted on a wall body; the box body auxiliary frame is fixed; template sealing is conducted; the holes are blocked; and a template is dismantled, and repeated use is achieved. According to the mounting technology of the box body on the masonry wall surface, by manufacturing the box body auxiliary frame, the problem of box body deviation is effectively solved, the influence on the moving directionof subsequent pipeline mounting is reduced, and materials and manpower are effectively saved; and by treating the reserved holes, the concave-convex quality defects of the box body are made up, thusthe holes around the box body are compactly sealed, vibrating is conducted after the holes are blocked, the phenomenon that after the template is dismantle, voids and pits occur is prevented, and theperceptual quality of the pre-buried box body is improved.
