UNDERGROUND DRAINAGE TOOL AND UNDERGROUND DRAINAGE STRUCTURE
To provide an underground drainage tool and an underground drainage structure allowing underground water to be smoothly discharged without causing clogging with particles such as sediment.SOLUTION: An underground drainage tool 1 for discharging the underground water penetrating the ground is provided with hollow pipe members 2, 3 and a connection pipe 4 in a hollow cylindrical shape connecting the pipe members to each other, wherein the connection pipe comprises a first connection part 10 into which the pipe member is inserted to be connected at one end side in a pipe axis direction as well as a second connection part 11 into which the other pipe member is inserted to be connected at the other end side in the pipe axis direction, and a conduit 15 having an inflow inlet 16 opened in a direction to the underground outward from the connection pipe between the first connection part and the pipe member to communicate the inside of the pipes with the ground is formed in the first connection part. The underground drainage structure uses the underground water drainage tool, the underground water drainage tool being arranged in a way the inflow inlet of the conduit and the pipe members are inserted into the ground in an attitude inclined downward and a downward tip of the pipe member is exposed on the ground surface from the underground as an inserted terminal.SELECTED DRAWING: Figure 6
【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】地中に浸透している地下水を排出する地中排水具１は、内部中空の管材２，３と、管材同士を接続する中空筒状の接続管４とを備え、接続管は、管軸方向の一端側に、管材が挿入されて接続される第１接続部１０を有すると共に、管軸方向の他端側に、他の管材が挿入されて接続される第２接続部１１を有し、第１接続部には、第１接続部と管材との間に、接続管外方の地中に向けて開口される流入口１６を有する、管材の内部を地中に連通させるための流路１５が形成されている。地中排水構造は、上記地中排水具を用い、地中排水具は、流路の流入口及び管材が斜め下向きとなる姿勢で地中に挿入され、管材の斜め下向き先端は、挿入終端として地中から地盤面に露出されるように配置される。【選択図】図６
