RETAINING WALL AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To make a retaining wall block hard to be dislocated even in a destructive earthquake, and to make a crushed stone hard to flow out backward even when a slope face in the rear of a retaining wall sinks.SOLUTION: A plurality of retaining wall blocks 10 are juxtaposed so that mutual front side surface plates 11 are laterally adjacent and mutual rear side brace plates 17 laterally separate more than a size quantity of a crushed stone 40. A front side guard material 20 having a mesh smaller than the crushed stone 40 is installed on a rear surface of laterally continuing two surface plates 11, and a rear side guard material 30 having a mesh smaller than the crushed stone 40 is installed on a front face of laterally juxtaposed two brace plates 17. At this time, upper side ends 20a and 30a of the front-rear guard materials 20 and 30 are separated in the longitudinal direction. Lower side ends 20b and 30b are also desirably separated in the longitudinal direction. A retaining wall 1 is constructed by filling the crushes stone 40 in a space S between the surface plates 11 and a slope face 8.SELECTED DRAWING: Figure 1
【課題】破壊的な地震等においても擁壁用ブロックをずれにくくすると共に、擁壁の背後の法面が陥没した場合にも、砕石を後方に流出しにくくする。【解決手段】複数の擁壁用ブロック１０を、前側の表面板１１どうしが左右に隣接し、後側の控板１７どうしが左右に砕石４０の大きさ分よりも離間するように並べる。そして、左右に連なる２つの表面板１１の後面に、砕石４０よりも小さい網目を備えた前側防護材２０を設置し、左右に並ぶ２つの控板１７の前面に、砕石４０よりも小さい網目を備えた後側防護材３０を設置する。このとき、前後の防護材２０，３０の上部側の端２０ａ，３０ａは、前後方向に離間させる。さらに、下部側の端２０ｂ，３０ｂも、好ましくは、前後方向に離間させる。そして、表面板１１と法面８との間の空所Ｓに砕石４０を充填して擁壁１を構築する。【選択図】図１
