EROSION CONTROL WEIR
PROBLEM TO BE SOLVED: To prevent leakage of soil cement when casting fluid soil cement inside a weir, without compromising workability and ensuring strength to withstand a lateral pressure load.SOLUTION: An erosion control weir (1) is constructed on a river, and includes an upstream side protective wall part (3) installed on an upstream side to face a stream, a downstream side protective wall part (4) installed on a downstream side to face the stream, a fluid filling material (5) cast in a space (S) formed between the upstream side protective wall part (3) and the downstream side protective wall part (4), and reinforcing members (7,9) installed in the space (S) on at least either of the protective wall parts (3,4) for reinforcing the protective wall parts (3,4).SELECTED DRAWING: Figure 1
【課題】堰堤の内部に流動性を有するソイルセメントを打設する際に、施工性を低下させることなく、側圧荷重に耐えることができ、ソイルセメントの漏れを防ぐこと。【解決手段】河川に設けられる砂防堰堤（１）であって、上流側に対向するように設けられる上流側保護壁部（３）と、下流側に対向するように設けられる下流側保護壁部（４）と、上流側保護壁部（３）と下流側保護壁部（４）との間に形成される空間（Ｓ）内に打設される流動性を有する中詰材（５）とを備え、空間（Ｓ）内において少なくとも一方の保護壁部（３，４）に設けられ、当該保護壁部（３，４）を補強する補強部材（７，９）を備える。【選択図】図１
