Problems solved by technology

Although this method can meet the design flow water elevation of the pipeline, due to the single size of the rectangular spacers and bricks and the inability to completely fit with various pipelines, it is easy to cause displacement of the pipeline under the influence of the concrete flow during the pouring of the subsequent concrete pipeline foundation, resulting in certain quality error, and even cause safety accidents, unable to meet the technical and safety requirements of pipeline foundation construction

Abstract

The invention discloses a municipal drainage concrete socket-and-spigot pipe pillow prefabricated plastic mold. The municipal drainage concrete socket-and-spigot pipe pillow prefabricated plastic moldcomprises a lower mold and an upper mold; the lower mold is of a frame structure with a hollow interior, and the bottom and the top of the lower mold are open; the interior of the frame structure isof a cuboid structure with a concave curved surface on one side face; a lower frame is arranged on the periphery of the bottom of the frame structure, and reinforcing ribs are evenly arranged on the side faces of the periphery of the frame structure; the upper mold is a sealing cover matched with the opening in the top of the lower mold; and reinforcing ribs are arranged on the upper surface of the upper mold, a demolding hole is formed in the middle of the upper mold, and an upper frame is arranged on the periphery of the upper mold. The plastic mold can prefabricate a pipe pillow, and installation of a socket-and-spigot pipe is facilitated.
