Claims (1)
- 壁体と地山、又は対向する壁体相互間に、板体の対向する面および下面を、U字状の合成樹脂フィルムで覆った板を設置し、該板の両側に発泡樹脂原料を吹き付け、発泡硬化させて発泡層を形成した後、
発泡層は、発泡樹脂原料の発泡反応による高温状態を経て常温まで自然冷却され、発泡層における気泡内の気体が収縮して発泡層が収縮することにより、U字状の合成樹脂フィルムが発泡層側へ引っ張られ、
発泡層の収縮後、板体を取り除き、更に、U字状の合成樹脂フィルムを発泡層から剥がし、該フィルムを取り除いて空間を形成させ、
その空間に発泡樹脂原料を吹き付けて、発泡硬化させることを特徴とする軽量盛土工法。
