REINFORCED SOIL STRUCTURE HAVING LONG-TERM DURABILITY ON SLOPE SURFACE, AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a reinforced soil structure having high long-term durability on a slope surface, and a construction method thereof.SOLUTION: A reinforcing material 3 is disposed in a cement-based injection material 4 and stiff-consistency mortar 6 filled in a hole 2 drilled in a ground from a slope surface 1. A pressure plate 8 having a through-hole 8a in a plate thickness direction is positioned leaving a prescribed interval from the slope surface and around the reinforcing material 3. A fixing member 9 is fitted on a head part of the reinforcing material 3 through the through-hole 8a of the pressure plate 8. A wire net 10 is installed along the slope surface 1 at a position to be hooked to the fixing member 9 or the head part of the reinforcing material 3. A mortar layer comprising a leveled mortar layer 7 and a sprayed mortar layer 11 is formed on the slope surface 1 to a height sufficient for covering the fixing member 9.SELECTED DRAWING: Figure 1
【課題】長期耐久性に優れた斜面の補強土構造とその施工方法を提供する。【解決手段】斜面１から地盤に穿孔した穴２に充填したセメント系注入材４及び固練りモルタル６内に補強材３を配置し、板厚方向に挿通孔８ａを有する受圧板８を前記斜面との間に所定の隙間を形成すると共に前記補強材３の位置にあわせて配置し、受圧板８の挿通孔８ａを介して補強材３の頭部に固定部材９を取り付け、固定部材９または補強部材３の頭部に係止される位置で斜面１に沿って金網１０を配置し、斜面１から固定部材９が埋設される高さまでモルタル均し層７、モルタル吹付け層１１からなるモルタル層を形成する。【選択図】図１
