PURPOSE:To prevent the degradation of a slope by a method in which main frames having a vertical wall are connected in a slant lattice form to the upside of the main part with a rectangular cross section by the first connector and the main frame at the lowermost end is connected with the second connector with an opening for draining to promote the draining work. CONSTITUTION:Main frames 2 are laid between first connectors 6 fixed to a slope by turning its water arresting part upwards. Also, the second-fourth connectors 7-9 are fixed to the lower, left and right, and upper sides of a drain frame 28, the ends of the main frames 2 are penetrated into the ground, and the frame 28 is buried by covering it with soil until the upper end of the vertical wall 4 of the main frames 2 is leveled with the ground surface. Water present in the surface layer of the slope flows down along the upside of the main frame 2, goes into the entrance paths of the first-third connectors 6-8, and further goes down inside the main part 3 of the other main frame 2. The arrested water is collected in the main part 3 and discharged from the opening of the second connector 7 at the lowermost end to the outside of the slope. |
