CONSTRUCTION METHOD OF SOIL RETAINING WALL
PROBLEM TO BE SOLVED: To prevent sediment from rising to the ground surface when extracting steel material.SOLUTION: A construction method of a soil retaining wall includes the steps of: forming a continuous wall 10 in the ground from a ground surface G to a first predetermined depth h1; forming a burying hole 13 penetrating the continuous wall 10 and extending from the ground surface G to a second predetermined depth h2 deeper than the first predetermined depth h1, injecting a filler into only a region from the ground surface G of the burying hole 13 to the first predetermined depth h1, and filling the region with a mixture 14 mixed with excavated soil and filler in the burying hole 13; forming an intervening layer 16 on the surface of a steel material 15; burying the steel material 15 having the intervening layer 16 formed thereon in the burying hole 13 so that the intervening layer 16 is interposed between the mixture 14 and the steel material 15 so that a soil retaining wall constructed; and pulling out the steel material 15 from the burying hole 13 while scraping off sediment adhering to the surface of the steel material 15 by an edge portion of a through hole formed in a steel material support portion 17 in which the mixture 14 is cured after using the soil retaining wall.SELECTED DRAWING: Figure 1D
【課題】鋼材の引き抜きの際に地表に土砂が上がるのを防止すること。【解決手段】地表面Ｇから第一所定深さｈ１までの地盤に連続壁１０を形成する工程と、連続壁１０を貫通して地表面Ｇから第一所定深さｈ１よりも深い第二所定深さｈ２に至る埋設穴１３を形成し、この埋設穴１３の地表面Ｇから第一所定深さｈ１までの領域のみに充填剤を注入し、埋設穴１３内の掘削土砂と充填剤を混合した混合物１４で前記領域を満たす工程と、鋼材１５の表面に介在層１６を形成する工程と、介在層１６が形成された鋼材１５を、介在層１６が混合物１４と鋼材１５との間に介在するように埋設穴１３に埋設して土留め壁を構成する工程と、土留め壁の使用後に、混合物１４を硬化させた鋼材支持部１７に形成された透孔の縁部によって、鋼材１５の表面に付着していた土砂を削ぎ落としながら、鋼材１５を埋設穴１３から引き抜く工程と、を備えた土留め壁の施工方法を構成する。【選択図】図１Ｄ
