| description | The invention discloses prefabricated box culverts and a quick positioning and constructing method. The box culverts are prefabricated in a factory and transported to a construction site. A groove with a rectangular section is excavated underground in the construction site, and steel plates are arranged on the two side walls of the groove; a bottom plate is arranged on the bottom face of the groove, H-shaped steel pieces are arranged longitudinally along the two sides of the bottom plate to form a longitudinal rail, and multiple steel wheels are evenly arranged on the upper surfaces of the H-shaped steel pieces; a move-in port is formed in the upper portion of the groove, and the box culverts are put on the longitudinal rail through the move-in port and transported to construction stations one by one through a dragger; the contact surfaces of all the box culverts are painted with epoxy resin glue, the box culverts are bonded through the epoxy resin glue in the contact process, and longitudinal prestressed bar |
