PROBLEM TO BE SOLVED: To provide a concrete casting frame for a steep incline earth and sand collapse preventive measure capable of increasing the strength by a new structure and assembly of a frame (wire netting) used for an earth and sand collapse preventive measure in a steep incline, at the same time, promoting work efficiency and reducing a construction cost. SOLUTION: The concrete casting frame for the steep incline earth and sand collapse preventive measure is so constituted that both ends of a vertical steel wire rod of 3 of the frame (wire netting) 1 consisting of a horizontal steel wire rod of a drawing 2 and the vertical steel wire rod of 3 are bent at 30 deg. to 50 deg. to fill the frame (wire netting) as a side shape of the drawing 2 and a side shape of the drawing 3 having a projection of a drawing 4 with the concrete or the mortar like drawings 4, 5 and 6. By the method, the assembly can be easily made to promote work efficiency, the strength is also increased, and a construction cost can be reduced.
