摘要： A cattle guard for highways and other thoroughfares, as an extension of a fence line to prevent cattle from crossing into forbidden areas, is made up of concrete slab sections faced with sheet steel and placed end-to-end across the thoroughfare. The sheet steel facing for each section is fabricated by interconnecting in side-by-side relationship a series of trough-like lengths of sheet steel or the like pre-bent to provide alternate, up-facing valleys and ridges and an undersurface to serve as a form having reverse valleys and ridges into and onto which is poured wet concrete to provide a structural concrete base for the section. The trough-like lengths are preferably interconnected by flanges extending integrally from respective sides of the valleys and overlapped to provide double thick, sheet steel traction surfaces for the upfacing ridges. Tie plates are provided to interconnect the slab sections and to facilitate handling and placement of the individual sections.
