To provide a joint device for a drainage channel, which can easily perform a water filling test.SOLUTION: A joint device 8 comprises a joint 9, a lid member 10, and a closing member 11. The joint 9 is disposed at a top portion located in the middle of a drainage channel 5, and an upstream drainage pipe 6 and a downstream drainage pipe 7 forming the drainage channel 5 are connected to the joint 9. The joint 9 comprises an internal space 9a, an opening 9b that faces the internal space 9a to the outside, a drainage inflow part 9c, and a drainage outflow part 9e. The lid member 10 is attached so as to close the opening 9b. The closing member 11 can be attached so as to close the drainage inflow part 9c. Therefore, at the time of the full water test, by closing the drainage inflow part 9c with the closing member 11, it is prevented that water entering the internal space 9a through the opening 9b so as to flow through the drainage outflow part 9e to the downstream drainage pipe 7, flows back to the upstream drainage pipe 6 through the drainage inflow part 9c.SELECTED DRAWING: Figure 3 【課題】満水試験を簡単に行うことができる、排水路用の継手装置を提供する。【解決手段】継手装置８は、継手９と蓋部材１０と閉塞部材１１とを備える。継手９は、排水路５の途中に位置する頂部部分に配置され、排水路５を形成する上流側排水管６および下流側排水管７が接続される。この継手９は、内部空間９ａと、その内部空間９ａを外部に臨ませる開口９ｂと、排水流入部９ｃと、排水流出部９ｅとを備える。蓋部材１０は、開口９ｂを閉鎖するよう取り付けられる。閉塞部材１１は、排水流入部９ｃを閉塞するよう取付け可能である。そこで、満水試験時に、閉塞部材１１で排水流入部９ｃを閉塞することで、排水流出部９ｅを通って下流側排水管９ｅへと流れるように開口９ｂから内部空間９ａに入れられた水が、排水流入部９ｃを通って上流側排水管６へと逆流するのが防止される。【選択図】 図３
