Abstract

PURPOSE:To prevent the push-out breakage of a slope by a method in which a latticed or netted flexible, corrosion-resistant synthetic polymer band is assembled into slope, and the frame is connected with a water-permeable material laid in the banking of the back side and set on the slope. CONSTITUTION:A slope frame 5 is made of a band 1 formed of a latticed or netted flexible, corrosion-resistant synthetic resin, etc., and the continuous long band 1 is rolled A before extension. A water-permeable material 2 made of a water-permeable and corrosion-resistant nonwoven fabric is attached to the back side of the frame 5, The band 1 is extended on the ground's surface under a condition that the edge of the band 1 is exposed in the front of the banking and the banking 4 is formed on the band 1 to a fixed height. The bent portions of the band 1 are connected and fixed to form the frame 5 on the front of the banking 4. The construction work of the slope frame can be effectively attained.
