示されている。このような方法により得たものを築堤と
することが考えられる。
入れ、積み重ねて盛土を行うと、脱水に伴う大きな沈下
のため所定の高さの築堤を粘土の入った袋を主体として
作成することが困難であった。
である。
た築堤方法は、高含水比状態の粘土を入れた多数の透水
性の袋を積み重ねる工程と、上記各袋から脱水せしめた
後上記各袋内に上記粘土を少なくとも１回再注入する工
程と、これら袋の上に盛土を行なう工程とより成ること
を特徴とする。
る。
比状態の粘土１を透水性の袋２に入れて積み重ね、この
積み重ねた状態で放置し、自重圧密と天日乾燥により粘
土１内の水を脱水する。この脱水に伴って、粘土層の厚
さは図２に示すように最終的に初期の高さの約１／２以
下になる。
うに上記袋２から脱水された水の量と略等しい量の上記
粘土１を上記各袋２の注入口３から再度注入する。ま
た、この放置による脱水と粘土の再注入を繰り返し行
い、最終的に粘土の注入がほぼ出来なくなった時点で、
図４に示すように袋２の上に盛土４を行なって築堤を形
成する。
端部上側に粘土１の注入口３を設けるのが好ましい。
記のとおりであるから下記のような効果が得られる。
は、一般に大量の粘土を現地で処分しなければならない
場合が多いが、本発明によれば一個の袋の中に従来の
１．５〜２．０倍の量の粘土を注入できるので、従来に
較べて、粘土の処理土量を大幅に増加させることが出来
る。
るので、従来と同数の袋を用いて所定の築堤の高さを確
保する際に、上部の盛土の厚さを従来より少なくするこ
とができる。
