PURPOSE:To prevent the degradation of sloped ground by a method in which a flow path through which water coming down the side of the main frame is directed to inside is porovided in a connector, and an opening through which water is drained to the outside of the sloped ground is provided in the connector on the lowest end. CONSTITUTION:Main frames 2 having vertical walls 4 on the upside of its main body 2 of a rectangular cross section are connected in an inclined grid form by connectors 6-11. The connectors 6-11 have flow paths through which water coming down the side of the main frame 2 is directed to inside, and the connectors 7 and 11 on the lowest end have openings 45 through which water coming down in the main frame 2 is drained to the outside of the slope. The connector 6 also has holes 19 for inserting the main frames 2, having an X-shaped planar form, and the connector 7 has the first holes 34 and the second holes 37 for inserting the main frames 2. Even in the case of the connectors 8-11, holes for inserting the main frames 2 are likewise provided, and each of the connectors 6-11 have cover respectively. |
