Abstract
【解決手段】高含水比粘土を袋体に注入し袋詰め脱水する布帛製の袋詰脱水袋において、袋体への注入部を、袋体に取り付けた筒状体から構成し、該筒状体の内部への突出長が30cm以上500cm以下となり、かつ筒状体の端部径が注入口の径の1.5倍以上となるように袋体の内外部に突出するように形成した構造とすること、さらに袋体として特定のカバーファクターの織物を使用することにより安定に効率よくろ過する。
【選択図】なし
Description
径の比が1.5よりも小さい場合はホースより注入する際、ホース出口から注入口先までの間に高含水比土壌が通過すると、筒状注入口が暴れ、効率よく注入を行うことができない。
CF=(DWp/1.1)1/2×MWp+(DWf/1.1)1/2×MWf
ここで、DWpは経糸総繊度(dtex)、MWpは経糸織密度(本/3.79cm)、DWfは緯糸総繊度(dtex)、MWfは緯糸織密度(本/3.79cm)である。また織組織、層数は特に限定されるものではない。例えば、織組織としては平組織、綾組織、サテンなどが好適に例示されるがこれらに限定されるものではない。また、層数も単層でもよいし2層以上の多層であってもよい。
土壌の作成:霞ヶ浦粘土を含水比300%の泥水状に調整した。
袋体の作成:ポリエステル製の平織物を縫製し、周長8m、長さ20mの袋材を作製した。
Claims (10)
- 高含水比粘土を袋体に注入し袋詰脱水する布帛製の袋詰脱水用袋体において、袋体への注入部が該袋体の内外部に突出するように形成された筒状体であり、該筒状体の袋体内部への突出長が30cm以上500cm以下、かつ該筒状体の外部へ突出した端部に設けられた注入口と内部へ突出した端部に設けられた排出口の口径比が1.5倍以上となるように形成された構造であることを特徴とする袋詰脱水用袋体。
- 袋詰脱水用袋体が合成繊維のマルチフィラメント糸織物からなる袋体であって、該合成繊維のマルチフィラメント糸織物のカバーファクターが1900〜2700の範囲である請求項1記載の袋詰脱水用袋体。
- 該合成繊維のマルチフィラメント糸が、ポリエステル、ナイロン、ビニロン、およびポリプロピレンの群から選ばれた少なくとも1種の合成繊維からなるマルチフィラメント糸である請求項2記載の袋詰脱水用袋体。
- 該ポリエステルのマルチフィラメント糸が、再生ポリエステルからなるマルチフィラメント糸である請求項2、3記載の袋詰脱水用袋体。
- 該再生ポリエステルが、回収ペットボトルより再生されたポリエステルである請求項4記載の袋詰脱水用袋体。
- 該再生ボリエステルが、回収ポリエステル繊維より再生されたポリエステルである請求項4記載の袋詰脱水用袋体。
- 該再生ポリエステルが、回収ポリエステルフィルムより再生されたポリエステルである請求項4記載の袋詰脱水用袋体。
- 該合成繊維のマルチフィラメント糸が、ボリ乳酸繊維からなるマルチフィラメント糸である請求項2記載の袋詰脱水用袋体。
- 水を含む土壌を、透水性の袋体内に入れた後、該袋体内の土壌に含まれる水分を袋体外に透過させて脱水するとともに、土壌を袋体内に残留させて、袋体内に封じ込めるに際し、該袋体として、請求項1〜8のいずれか1項に記載の袋詰脱水用袋体を使用することを特徴とする含水土壌の封じ込め方法。
- 土壌がさらに有害物質を含み、土壌とそれに含まれる有害物質を袋体内に残留させて、袋体内に封じ込める請求項9記載の含水土壌の封じ込め方法。
