THREE-DIMENSIONAL SCREEN FOR DUST REMOVAL
To secure water permeability at a higher level while appropriately capturing a contaminant in flowing water.SOLUTION: A three-dimensional screen S1 includes: a screen body part 2 having a plurality of first water passages 3A penetrating in a thickness direction; and projection water pipe parts 4 which project toward the upstream side at positions adjacent to the first water passages 3A of an upstream side face U2 of the screen body part 2, and have second water passages 3B penetrating in the thickness direction. Out of the first water passages 3A and the second water passages 3B, at least the second water passages 3B are formed so that passage cross-sectional areas on the downstream side are relatively larger than passage cross-sectional areas on the upstream side.SELECTED DRAWING: Figure 4
【課題】流水中の夾雑物を適切に捕捉しながら、通水性をより高度に確保する。【解決手段】立体スクリーンＳ１は、厚み方向に各々貫通する複数の第１通水路３Ａを有するスクリーン本体部２と、このスクリーン本体部２の上流側面Ｕ２の前記第１通水路３Ａに隣接する位置において各々上流側に向かって突出し、かつ厚み方向に貫通する第２通水路３Ｂを有する突き出し通水管部４と、を備える。第１通水路３Ａ及び第２通水路３Ｂのうち、少なくとも第２通水路３Ｂは、上流側の通路断面積よりも相対的に下流側の通路断面積が大きくなるように形成されている。【選択図】図４
