Guide limiting block for pipe shoe and installation method of guide limiting block

The invention discloses a guide limiting block for a pipe shoe and an installation method of the guide limiting block. The contour of the cross section of the guide limiting block is in a trunk shape, and the guide limiting block comprises a connecting edge, an inwards-concave section, a guide edge, a limiting edge and an outer contour edge which are connected end to end in the clockwise direction; the connecting edge, the inwards-concave section, the guide edge, the limiting edge and the outer contour edge extend in the thickness direction to form a connecting face, an inwards-concave face, a guide face, a limiting face and an outer contour face respectively; the guide limiting block is of a trunk-shaped structure, the connecting face is used for fixing, the inwards-concave face enlarges the gap between the guide limiting block and a pipe shoe bottom plate, welding and coating are facilitated; the guide face and the limiting face are arranged to limit the movement direction of the pipe shoe bottom plate and
