PURPOSE:To form an uneven surface on a sloped ground by strongly laying a columnar block having a crosswise groove extending in the longitudinal direction on its left and right-handed both sides and a plate block having connected recessions on its four side faces. CONSTITUTION:An angular columnar block 1 has a crosswise groove 4 continuously extending in the longitudinal direction of its left and right both sides and a vertical groove 8 connecting to its both ends. Also, a plate block 10 has a tiered portion 15 connecting to its four side faces and recessions 16 connecting to each other with a depth deeper than the tiered portion 15. The plural blocks 1 are set by positioning vertically its crosswise groove 4 to the slope, the plate block is set between the blocks 1 by facing the recessions 16 to the crosswise groove 4. A solidifying agent 23 is packed into the spaces 22 between the recessions 16 and the crosswise groove 4 to form a revetment for river. |
