▎ 摘  要

NOVELTY - The method involves providing molds to form the first side (11), the second side (12), the third side (13), and the fourth side (14). The molds are constructed to form a central hole in each hinge element (24). A material suitable for molding and placing the material in molds is provided to form the sides. The sides are removed from the molds after the curing of the material in the molds. The sides are assembled to form the foldable plastic (10), while the sides are still hot from the molding process. The hinge pins (26) are inserted into the central holes of the spaced-apart hinge elements to form the hinges to prevent the sides from warping during cooling. The composite is a glass fiber-reinforced thermoplastic composite and polymer-graphene composite. The thermoplastic is polypropylene. The plastic is a polymer. USE - Method for forming a foldable plastic for providing protection for below ground devices, such as water meters, valves and telecom hardware. ADVANTAGE - The foldable plastic takes up reduced space when folded. It is durable, lightweight, and capable of being located in roadways or driveways and withstanding heavy loads. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of foldable plastic for providing protection for below ground devices. Foldable plastic (10) First side (11) Second side (12) Third side (13) Fourth side (14) Hinge element (24) Hinge pins (26)
