Description
<実施例>
図3は土槽および地盤の寸法図を示したものである。図3(1)は上面図、(2)は横断面図、(3)は縦断面図である。図3に示されるように、土槽8内に2枚一組で中立状態になるように継手を嵌合した長さ2mの遮水用鋼矢板6を建て込み、5号珪砂を1300mmの深さまでホッパーから約1mの高低差で自然落下させ、井戸水を1000mmの深さまで注水して地盤7を作成した。
2 爪底部
3 止水材
4 土砂
5 ベントナイトスラリー(粘性流体)が浸透した土砂
6 U形鋼矢板(鋼矢板)
7 地盤
8 土槽
9 継手
Claims (1)
- 断面視で継手の爪底部内面側に止水材が充填される凹溝が形成された鋼矢板を打設嵌合した後に、前記凹溝にベントナイトスラリーを注入して継手内の異物を除去し、その後、前記凹溝から前記ベントナイトスラリーよりも大きな比重を持つベントナイトペースト止水材を充填することを特徴とする鋼矢板の継手の止水方法。
