PURPOSE: A prefabricated synthetic resins ridge between rice fields is provided to perfectly prevent a leakage by connecting a connection unit in a multi-layer and to be strongly connected without movements. CONSTITUTION: A prefabricated synthetic resins ridge between rice fields (1) comprises an upper plate (1a), an accommodation groove, a connection piece (1e), and a connection groove unit. The upper plate comprises a ridge body, a sliding prevention surface, and a reinforcing member. A horizontal partition and a vertical partition are installed in the accommodation groove so that the accommodation groove partitions an opening part. The connection piece is formed on the surface of a left wall in the accommodation groove and forms a short protrusion (1e') on the center of a protrusion end. The connection groove unit is formed on the surface of a right wall of the accommodation groove and is formed to be concave so that the connection piece is connected. A protrusion is formed on the connection groove unit and forms a connection unit so that the short protrusion of the connection piece is connected. |
