PRESSURE RECEIVING PLATE BACKFILLING MATERIAL AND SLOPE REINFORCING STRUCTURE
To provide a pressure receiving plate backfilling material and a slope reinforcing structure that are easy to construct, have high construction accuracy, and can uniformly transmit an axial force of a tensile material applied to the pressure receiving plate to a slope.SOLUTION: A pressure receiving plate backfilling material 1 of the present invention comprises at least: a bag body 10 having a flat bag main body 11 having a filling space S inside, a filling port 12 connecting the outside of the bag main body 11 and the filling space S, and an insertion hole 13 penetrating both sides of the bag main body 11 without communicating with the filling space S; and a porous spacer 20 made of synthetic resin disposed within the bag main body 11. A slope reinforcement structure A of the present invention includes at least: a pressure receiving plate a1 arranged on the slope; a tensile member a2 whose head is connected to the pressure receiving plate a1 and whose tip penetrates into a drilled hole in the slope; an injection material a3 injected around the tensile material a2 in the drilled hole; a pressure receiving plate backfilling material 11 inserted between a back surface and the slope of the pressure receiving plate a1 by inserting the tensile material a2 into the insertion hole 13; and a curable filler a5 filled in the filling space S of the pressure receiving plate backfilling material 11.SELECTED DRAWING: Figure 1
【課題】施工が容易で施工精度が高く受圧板にかかる引張材の軸力を斜面へ均一に伝達可能な受圧板裏込材及び斜面補強構造を提供すること。【解決手段】本発明の受圧板裏込材１は、内部に充填空間Ｓを有する扁平な袋体本体１１と、袋体本体１１の外部と充填空間Ｓとを接続する充填口１２と、充填空間Ｓと連通せずに袋体本体１１の両面を貫通する挿通孔１３と、を有する袋体１０と、袋体本体１１内に配置した合成樹脂製の多孔性スペーサ２０と、を少なくとも備える。本発明の斜面補強構造Ａは、斜面に配置した受圧板ａ１と、頭部を受圧板ａ１と連結し先端を斜面の削孔に貫入した引張材ａ２と、削孔内における引張材ａ２の周囲に注入した注入材ａ３と、挿通孔１３内に引張材ａ２を挿通させて、受圧板ａ１の背面と斜面の間に介挿した受圧板裏込材１１と、受圧板裏込材１１の充填空間Ｓ内に充填した硬化性の充填材ａ５と、を少なくとも備える。【選択図】図１
