SAND CONTROL WEIR
PROBLEM TO BE SOLVED: To provide a sand control weir which: ensures safety during construction; preserves a natural environment and landscape; and reduces time, effort and a cost of the construction while securing necessary strength.SOLUTION: A sand control weir comprises: a pair of overflow prevention sections (10a and 10b) which prevent mudflow, flowing down from an upstream side of a river, from overflowing the same; a permeate section (20) which is arranged between the overflow prevention sections and allows water to flow therethrough; and artificial mounds (30a, 30b, 30c and 30d) which are constructed on planes, facing the upstream side and a downstream side, at sleeve portions of the overflow prevention sections next to the ground along the river. The artificial mounds respectively have protection wall sections (31a, 31b, 31c and 31d) which cover at least external faces of the artificial mounds facing the river. Or, the sand control weir comprises: the overflow prevention section (10); and the artificial mounds (30a, 30b, 30c and 30d) which are constructed on the planes, facing the upstream side and the downstream side of the river, at the sleeve portions of the overflow control section (10) next to the ground along the river and have the protection wall sections (31a, 31b, 31c and 31d) covering at least the external faces of the artificial mounds facing the river.SELECTED DRAWING: Figure 1
【課題】必要な強度を確保しつつ、施工時の安全性や自然環境、景観の確保及び施工の手間、施工コストの低減を図ること。【解決手段】河川の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、非越流部の、河川の地山に隣接する袖部における上流側及び下流側を臨む面に設けられた人工地山（３０ａ，３０ｂ，３０ｃ，３０ｄ）とを備え、人工地山は、少なくとも前記河川を臨む外面を覆う保護壁部（３１ａ，３１ｂ，３１ｃ，３１ｄ）を有する。また、河川の上流側から流れ込む土石流の越流を阻止する非越流部（１０）と、非越流部（１０）の、河川の地山に隣接する袖部における上流側及び下流側を臨む面に設けられた人工地山（３０ａ，３０ｂ，３０ｃ，３０ｄ）とを備え、人工地山は、少なくとも河川を臨む外面を覆う保護壁部（３１ａ，３１ｂ，３１ｃ，３１ｄ）を有する。【選択図】図１
