BANKING STRUCTURE, CONSTRUCTION METHOD OF BANKING STRUCTURE, AND REPAIR METHOD OF BANKING STRUCTURE
To provide a banking structure capable of efficiently discharging water in a banking.SOLUTION: A banking structure configured to form an oblique plane 11 is provided with: a capillary barrier layer 3 with a predetermined thickness D formed with coarse-grained soil and generally horizontally extending from the oblique plane 11 toward an inner part of the banking with a predetermined length L; a water retaining area 5 formed with grain soil having a diameter smaller than that of the coarse-grained soil, and arranged to abut an upper surface of the capillary barrier layer 3; and a discharging pipe 4 with open holes extending to a boundary between the capillary barrier layer 3 and the water retaining area 5 and collecting water penetrated in the water retaining area 5, and having a discharging opening 41 arranged in the oblique plane 11. Water drainage set units 2 with the capillary barrier layer 3, the discharging pipe 4 with open holes, and the water retaining area 5 taken as one set are placed apart from each other in a height direction of the oblique plane 11.SELECTED DRAWING: Figure 1
【課題】効率的に盛土内部の水を排水させることが可能な盛土構造を提供する。【解決手段】傾斜面１１が形成される盛土構造であって、所定の厚さＤで傾斜面１１から盛土内部に向けて略水平に所定の長さＬで延伸される粗粒土によって形成されたキャピラリーバリア層３と、キャピラリーバリア層３の上面に接して設けられる粗粒土より粒径が細かい土粒子によって形成された保水域５と、キャピラリーバリア層３と保水域５との境界付近に延伸されて、保水域５に浸透した水を取り込むとともに傾斜面１１に吐出口４１が設けられる有孔排水管４とを備えている。そして、キャピラリーバリア層３、有孔排水管４及び保水域５を１組とする排水組部２は、傾斜面１１の高さ方向に間隔を置いて複数設けられる。【選択図】図１
