ANCHOR PIPE AND SLOPE FACE REINFORCEMENT METHOD
To provide an anchor pipe that is suitable for being used in a slope face reinforcing construction work for preventing collapse of a slope face much generated in rainfall time, and a slope face reinforcement method performed using the anchor pipe.SOLUTION: An anchor pipe 1 includes a pipe 2 whose both ends are opened, a branch piece 5 formed in a tip side region 6 of the pipe 2, and a stuffing member 4 for expanding the branch pipe 5 in the ground G by being pressed into the tip side region 6 of the pipe 2 from a rear end opening 16 of the pipe 2. The pipe 2 is inserted into a prepared hole 21 formed on a slope face W from the tip side, and a stuffing member 4 is pressed into the pipe 2. Since the stuffing member 4 expands the branch piece 5 in the ground G, the pipe 2 is strongly fixed to the ground G. Therefore, the slope face is reinforced by arranging a slope face pressing member between the pipe and the slope face, and a reinforcement action maintains by draining ground water in the slope face through the pipe 2.SELECTED DRAWING: Figure 1
【課題】降雨時に多く発生する法面崩壊を防止するための法面補強工事に用いて好適なアンカーパイプと、このアンカーパイプを用いて行う法面補強工法を提供する。【解決手段】アンカーパイプ１は、両端が開口したパイプ２と、該パイプ２の先端側領域６に形成される分岐片５と、パイプ２の後端開口部１６からパイプ２の先端側領域６内へと圧入されることにより分岐片５を地盤Ｇ内で拡開させる詰め込み部材４と、を備える。法面Ｗに形成された下穴２１にパイプ２を先端側から挿入し、パイプ２内へと詰め込み部材４を圧入する。地盤Ｇ内で詰め込み部材４が分岐片５を拡開させるので、パイプ２が地盤Ｇに対して強固に固定される。よって、法面押圧部材をパイプと法面との間に配設することで法面が補強され、パイプ２を通して法面内の地下水を排水させることで補強作用が持続する。【選択図】 図１
