＼本発明の効果＼
本発明は以上説明したようになるので、次のような効果
を期待することかできる。\Effects of the Present Invention\ Since the present invention has been described above, the following effects can be expected.
（イ＼’４ｒＹｉ来のように、土嚢を積め上げて壁体を
構築Ａるだけては、土嚢壁間に投入した土圧によって１
、嚢壁が倒れて、盛土が崩壊するおそれがある。(As in I\'4rYi, building a wall by piling up sandbags is only possible if the earth pressure applied between the walls of the sandbags increases.)
, there is a risk that the cap wall will collapse and the embankment will collapse.
それに列して本発明は、土嚢に補強シートを取り付け、
その補強シート＋、に盛土材料を投入する構造である。In line with this, the present invention attaches a reinforcing sheet to the sandbag,
The structure is such that embankment material is put into the reinforcing sheet +.
即ち、盛土材料内に補強シートが埋設されるため、摩擦
抵抗によって補強シートが盛土材料内に定着される。That is, since the reinforcing sheet is buried within the embankment material, the reinforcing sheet is fixed within the embankment material due to frictional resistance.
従って、補強シートが引き抜けることがないため、土嚢
か倒れるのを防止することができ、安定した盛土を築造
することができる。Therefore, since the reinforcing sheet cannot be pulled out, the sandbags can be prevented from falling over, and a stable embankment can be constructed.
さらに、剛体壁と土嚢を連結金具によって結合すること
により、より−・層盛土の安定性を向上することができ
る。Furthermore, by connecting the rigid wall and the sandbag with a connecting fitting, the stability of the layered embankment can be further improved.
〈口）剛体壁と土嚢の結合を、特殊なリンク結合とする
ことにより、盛土部の沈下変形による補強シートの切断
を防止することかできる。(Explanation) By connecting the rigid wall and the sandbag with a special link connection, it is possible to prevent the reinforcing sheet from being cut due to sinking deformation of the embankment.
くハ〉剛体壁と土嚢部との間には、砂利等のυ１水材を
充填する。Kuha〉Fill υ1 water material such as gravel between the rigid wall and the sandbag part.
そのため、剛体壁背面の排水を可能にすることができる
。Therefore, it is possible to drain water from the rear surface of the rigid wall.
従って、剛体壁が浸水によって脆弱になったり、水圧で
崩壊するなとのおそれかない。Therefore, there is no fear that the rigid wall will become brittle due to water intrusion or collapse under water pressure.
、二〉従来の土嚢は、袋体に人力で砂等の充填材を充填
