To provide a drain tube inserted after drilling with a double tube, causing no co-lifting.SOLUTION: Provided is a drain tube 1 remaining in a hole H drilled by using a double tube on a slope, after drawing out an outer tube D of the double tube. The drain tube has multiple joint cylinders 10 of prescribed length having slits 11 communicating inner and outer circumferences with each other and extending by connecting in the axial direction, a joint 30 for inserting each of two joint cylinders 10 so as to butt with each other, and a lid 20 being a bottomed cylinder fitted into the topmost joint cylinder 10, with a bottom part net-likely formed. On a side periphery of the joint cylinder 10 and/or the joint 30 and/or lid 20, three or four legs 22, 32 expanded backward in the insertion direction and falling and restoring following a diameter of the hole H and rotation symmetrical in relation to a shaft are provided.SELECTED DRAWING: Figure 2
【課題】二重管削孔後に挿入する、共上がりしない水抜き管を提供すること。【解決手段】斜面に二重管を用いて削孔された穴Ｈに、二重管の外管Ｄを抜脱したあと存置させる水抜き管であって、軸方向に継いで延伸させていく、内外周を連通する切れ込み１１を設けた所定長さの複数の継ぎ筒１０と、二つの継ぎ筒１０が突き合うようにそれぞれを内挿させるジョイント３０と、最先端の継ぎ筒１０にはめる有底筒であって、底部が網様に形成されている蓋２０と、を具備し、継ぎ筒１０および／またはジョイント３０および／または蓋２０の側周に、差し込み方向の後ろ側に広がり、穴Ｈの径に追従して倒伏および復帰する、軸に対して回転対称な３本または４本の足２２，３２を設けたことを特徴とする水抜き管１。【選択図】図２
