ルパイル余剰液の再利用プラントに関する。[Detailed Description of the Invention] The present invention is widely applied to the construction of mountain retaining walls and water-stop walls because it is easy to construct, has low construction costs, and is a low-pollution construction method. In order to reuse the surplus liquid mixed with soil, water, cement, bentonite, etc. that is unavoidably generated during the fill pile creation process, the surplus liquid generated during the soil pile creation is recycled. The present invention relates to a fill pile surplus liquid reuse plant that is provided with a separation device that separates and removes components, and a 31-mixer that mixes the recycled liquid containing the separated cement components with additional cement.
