PRESSURE RECEIVING PLATE BACKFILLING MATERIAL AND SLOPE REINFORCING STRUCTURE

Japanese Patent JP2023128292

A

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
