EARTH RETAINING WALL STRUCTURE MEMBER, CONSTRUCTION METHOD FOR EARTH RETAINING WALL, AND UNDERGROUND CUTTING METHOD

To provide an earth retaining wall structure member that makes it possible to perform a cutting process of an earth retaining wall more easily.SOLUTION: An earth retaining wall structure member includes a core material 8a, and a hanger 10a provided on an upper end of the core material 8a. The core material 8a is a composite in which inorganic fibers are mixed in a resin form. The hanger 10 is attachably and detachably bonded to the core material 8a. Alternatively, an earth retaining wall structure member includes a core material 8a and a hanger provided on one end in a surface direction of the core material 8a. The core material 8a is a composite in which inorganic fibers are mixed in a resin form, and the hanger is a composite in which inorganic fibers are mixed in a resin form.SELECTED DRAWING: Figure 1 【課題】より容易に土留め壁の切削工程を遂行することができる土留め壁構造部材。【解決手段】芯材８ａと、前記芯材８ａの上端に設けられた吊り具１０ａと、を有し、前記芯材８ａは、発泡樹脂中に無機繊維を混在させた複合体であり、前記吊り具１０ａは、前記芯材８ａに着脱可能に接合されていることよりなる。また、芯材８ａと、前記芯材８ａの面方向の一端に設けられた吊り具と、を有し、前記芯材８ａは、発泡樹脂中に無機繊維を混在させた複合体であり、前記吊り具は、発泡樹脂中に無機繊維を混在させた複合体であることよりなる。【選択図】図１
