UNDERGROUND DRAINAGE IMPLEMENT AND UNDERGROUND DRAINAGE STRUCTURE
To provide an underground drainage implement and an 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 connects in series drainpipes 2, 3 that are inserted obliquely downward into the ground to get underground water w to circulate. The connection pipe comprises: an annular water passage 8 formed along the inner periphery of the connection pipe; an underground water drainage opening 10 that is made on the water passage on one side in the radial direction of the connection pipe making the water passage communicate with the inner side of the connection pipe; and an inflow passage 11 that has an underground water flow-in opening 12 that opens facing the underground, and connects to the water passage on the other side in the radial direction of the connection pipe. With the drainpipes being inserted into the ground, the water drainage opening is positioned at the upper side of the connection pipe while the inflow passage is positioned at the bottom side of the connection pipe.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を直列接続する中空筒状の接続管４を有し、接続管には、当該接続管の内周に沿って形成された環状の通水路８と、接続管の径方向一方側で通水路に開口され、通水路を接続管内方へ連通させる地下水の排水開口１０と、地中に面して開口された地下水の流入開口１２を有し、接続管の径方向他方側で通水路に接続される流入路１１とが備えられ、排水管の地中への挿入により、接続管の上側に排水開口が位置され、接続管の下側に流入路が位置される。【選択図】図３
