WATER COLLECTION SEGMENT AND WATER COLLECTION FACILITY
To provide the water collection facility that has a large area of a water permeable layer with respect to an outer peripheral surface of the water collection segment and has a high water collecting efficiency and a simple structure.SOLUTION: The water collection segment 3 formed in a substantially circular arc plate shape comprises: a segment body 5 that is formed on an inner peripheral side and has water cut-off performance and proof strength; and a porous layer 6 having water permeability that is laminated on an outer peripheral side of the segment body 5 and is exposed at both ends in a circumferential direction and a width direction. The porous layer 6 is made of porous concrete, and water flowing in from the natural ground flows out from a lower end part in the circumferential direction. In a water collection tunnel in which the water collecting segments 3 are connected in the circumferential direction and an axial direction, the water that has penetrated into the porous layer 6 of the water collection segment 3 at an upper part of a segment ring flows down the porous layer 6 of the water collection segment 3 connected to a lower part and is collected in the water collection tunnel through an intake pipe at a bottom.SELECTED DRAWING: Figure 2
【課題】集水セグメントの外周面に対する透水層の面積を大きくとることができる上に、集水効率が高くて構造が簡単である。【解決手段】集水セグメント３は略円弧版状に形成され、内周側に形成された止水性及び耐力性を備えたセグメント本体５と、セグメント本体５の外周側に積層されて周方向及び幅方向の両端部に露出している透水性を有するポーラス層６と、を備えている。ポーラス層６はポーラスコンクリートからなり、地山から流入した水は周方向の下端部から流出する。集水セグメント３を周方向と軸方向に連結した集水用トンネルでは、セグメントリングの上部の集水セグメント３のポーラス層６に浸透した水が下方に接続した集水セグメント３のポーラス層６を流れ落ちて、底部の取水管を通して集水用トンネルに集水される。【選択図】図２
