PROBLEM TO BE SOLVED: To provide a portable slope which is light in weight and easy to carry, can be easily manufactured at a low cost in an optimum size with excellent workability, is excellent in a fixing performance, is not easily broken by a high impact resistant performance of a slope edge part and a derailing prevention wall, and has an excellent repair performance.SOLUTION: A portable slope includes at least two pieces of plywood for which plate materials made of fiber reinforced plastic (FRP) are bonded to both front and back surfaces of a square core material composed of a foamable resin. The pieces of plywood have tapered structures 4 and 5 for dissolving the level difference of the pieces of plywood themselves at respective upper and lower ends in a passing direction and have a structure for which an outer side face to the passing direction is fitted by a frame member 9, two or more pieces of plywood are arranged side by side with respect to the passing direction, opposed side faces of the pieces of plywood are connected by a sheet material 6, and the pieces of plywood are made foldable so as to overlap with each other. Further, an impact absorber 7 is mounted on the outer periphery of a part to be fitted to the tapered structure of the plywood, in a frame member. |
