PURPOSE:To easily set slope frames of uniform quality by a method in which steel pipes are set crosswise on a slope, a metal netting is provided on the periphery of the piles, and then cement mortar is sprayed onto the metal netting. CONSTITUTION:Plural vertical steel pipes 1 are set from upside to down side of a slope along the inclination of the slope, and plural cross steel pipes 2 are set in the direction of crossing the vertical steel pipes 1. The vertical and cross steel pipes are fixed to the slope by burying anchors 3 piercing these pipes in the slope. A metal netting 9 for protection and cement mortar-spraying purposes is covered on these vertical and transversal steel pipes 1 and 2, and then cement mortar is sprayed onto the periperies of these pipes 1 and 2. |
