WATER COLLECTING STRUCTURE AND WATER COLLECTING STRUCTURE CONSTRUCTION METHOD

To collect underground water with a water collecting pipe without arranging a vertical drain on both ends of the water collecting pipe extending in a lateral direction along a bottom surface of a bottom part of a building.SOLUTION: A water collecting structure 100 includes: a shaft 110 having a drainage facility 112 for draining underground water; a culvert 102 which extends underneath a bottom part 20 of a building 10 from the shaft 110 and flows the underground water to the shaft 110; and a plurality of first water collecting pipes 150 which extend in a lateral direction along the bottom surface 20A of the bottom part 20 of the building 10 from the culvert 102 and collect the underground water to the culvert 102.SELECTED DRAWING: Figure 1 【課題】建物の底部の底面に沿って横方向に延びる集水管の両端部に鉛直ドレーンを配置することなく、地下水を集水管で集水する。【解決手段】集水構造１００は、地下水を排水するための排水設備１１２を備えた立坑１１０と、立坑１１０から建物１０の底部２０の下に延び地下水を立坑１１０へ流すカルバート１０２と、カルバート１０２から建物１０の底部２０の底面２０Ａに沿って横方向に延び地下水をカルバート１０２に集水する複数の第一集水管１５０と、を備えている。【選択図】図１
