CONSTRUCTION METHOD FOR SAND CONTROL WEIR
PROBLEM TO BE SOLVED: To reinforce strength and reduce a construction cost.SOLUTION: A construction method for a sand control weir (100), which has a pair of overflow prevention sections (10a and 10b) which prevents mudflow, flowing down from an upstream side of a river, from overflowing the same and a permeate section (20) which is arranged between the overflow prevention sections and allows water to flow therethrough, comprises the processes to: construct upstream wall sections (1a and 1b); construct downstream wall sections (2a and 2b); connects side wall sections (3a and 3b) to the downstream wall sections at a side of the permeate section; connect curved wall sections (4a and 4b) which are partially curved to the upstream wall sections and the side wall sections; fill a space surrounded by these wall sections with filling materials (5a and 5b); construct the permeate section (20), which traps soil and stones and allows water to flow therethrough, between the pair of overflow prevention sections; and construct slopes (F1 and F4), at the upstream wall sections and the curved wall sections, with downward slopes from upper edges to lower edges toward an upstream side.SELECTED DRAWING: Figure 1
【課題】強度の向上を図ると共に、コストの低減を図ること。【解決手段】上流側から流れ込む土石流の越流を阻止する一対の非越流部（１０ａ，１０ｂ）と、非越流部の間に設けられ、流水を透過する透過部（２０）とを備える砂防堰堤（１００）の施工方法であって、上流壁部（１ａ，１ｂ）を構築する工程と、下流壁部（２ａ，２ｂ）を構築する工程と、透過部側で下流壁部に連続する側壁部（３ａ，３ｂ）を構築する工程と、上流壁部と側壁部とに連続し、少なくとも一部が曲面状に形成された湾曲壁部（４ａ，４ｂ）を構築する工程と、これらの壁部に囲まれた空間内に中詰材（５ａ，５ｂ）を充填する工程と、一対の非越流部の間に土石を捕捉すると共に流水を透過する透過部（２０）を構築する工程と、上流壁部及び湾曲壁部に、上端から下端に向かうにつれて上流側に向けて下方に傾斜する法面（Ｆ１，Ｆ４）を形成する工程と、を有する。【選択図】図１
