PURPOSE:To prevent the run-off soil in a slope frame by a method in which the angle between the rising side and bottom of the valley side of constituent pieces in the vertical direction of a slope, among slope frame materials, is made into an acute angle. CONSTITUTION:Two constituent pieces 4 of a trapezoildal form are joined into V-shaped right angle in such a way that the angle between the rising side 5 and bottom side 6 of the valley side of the constituent pieces 4 becomes 75 deg. to form a slope frame material. The joined ends of the slope frame material are positioned on each side and fixed to th slope with anchor pins, etc., and the ends of the valley side of the next row are lapped with the ends of the mountain side and fixed. When the slope frames of an angle theta of 75 deg., a rising wall of about 70 deg. to the horizontal face is obtained to effectuate a good soil holding effect. |
