UNDERGROUND DRAINAGE IMPLEMENT AND UNDERGROUND DRAINAGE STRUCTURE
To provide an underground drainage implement and underground drainage structure that can smoothly discharge underground water without experiencing clogging caused with particle content of sediment and the like.SOLUTION: An underground drainage implement comprises a hollow cylindrical connection pipe 4 which, in order to connect in series drainpipes 2, 3 that are inserted obliquely downward into the ground to get underground water w to circulate, has the drain pipes inserted into it from its end part openings 4a, 4b in the longitudinal direction inward. The connection pipe has a spiral projecting stripe 15 formed on its inner periphery from its end part opening 4a inward. There is formed a spiral water passage 16 from the end part opening of the connection pipe inward, being demarcated by the projecting stripe and a first drainpipe 2 inserted into a first connection part 10 of the connection pipe. A drain part 16a that is the innermost end of the water passage in the connection pipe communicates with the inner side of the connection pipe, while an inflow part 16b that is the start end of the water passage at the end part opening of the connection pipe communicates with the underground.SELECTED DRAWING: Figure 3
【課題】土砂などの粒分によって目詰まりが生じることがなく、地下水を円滑に排出することが可能な地中排水具及び地中排水構造を提供する。【解決手段】地中に斜め下向きに挿入されて地下水ｗを流通させる排水管２，３を直列接続するために、端部開口４ａ，４ｂから長さ方向に内奥へ向けて、排水管が挿入される中空筒状の接続管４を備え、接続管の内周には、端部開口４ａから内奥へ向けて、螺旋状に凸条１５が形成され、凸条と接続管の第１接続部１０に挿入される第１排水管２とで区画して、接続管の端部開口から内奥へ向けて螺旋状の通水路１６が形成され、接続管の内奥に位置する通水路の終端である排水部１６ａが接続管内方に連通されると共に、接続管の端部開口に位置する通水路の始端である流入部１６ｂが地中と連通される。【選択図】図３
