PURPOSE:To prevent the degradation of sloped ground by a method in which plural long vertical slits are drilled in the steel tube on the upper end of each anchor rod, and each arc-shaped soil pressing plate between the slits is tensely connected to the plates of the adjacent anchor rods. CONSTITUTION:In the stabilization work of sloped ground, an anchor rod 5 used is made up of a steel pipe 7, long vertical slits 8, arc-shaped soil pressing plates 9, and connectors 6. The upper end of each anchor rod 5 is made of the steel pipe 7, and the long vertical slits 8 are formed in plural arc-shaped soil pressing plates 9. The plates 9 of the adjacent anchor rods 5 are tensely connected with connectors 6 and opened radially to widen the pressure propagating area. All the underground area where the anchor rods 5 are driven can thus be integrated to provide sufficient resistance to degradation of the sloped ground. |
