CONTINUOUS FIBER-REINFORCED EARTH METHOD
PROBLEM TO BE SOLVED: To provide a continuous fiber-reinforced earth method, capable of restraining an increase in soil hardness and a rise of pH to a necessary minimum limit, while improving strength of continuous fiber-reinforced earth, by mixing an additive such as cement with sandy soil.SOLUTION: The additive is added so that uniaxial compression strength of a mixture of the sandy soil and the additive becomes within a range of 30kN/m-150kN/m. Long fiber, for example, polyester fiber is used as continuous fiber. Normal Portland cement, highly-early -strengthening cement, a lime calcium-based solidification material, cement lime, gypsum and magnesium can be applied as the additive.
【課題】砂質土にセメント等の添加材を混合して連続繊維補強土の強度を向上させつつ、土壌硬度の増加とｐＨの上昇を必要最低限に抑制することが出来る連続繊維補強土工法の提供。【解決手段】添加材は砂質土と添加材の混合物の一軸圧縮強度が３０ｋＮ／ｍ２〜１５０ｋＮ／ｍ２の範囲内となるように添加される。連続繊維としては、長繊維、例えばポリエステル繊維等を用いる。添加材としては、普通ポルトランドセメント、早強セメント、石灰、カルシウム系固化材、セメント石灰、石膏、マグネシウム等が適用可能である。【選択図】図３
