JOINT MEMBER FOR BURIED PIPE IN PRECAST CONCRETE WALL AND USE THEREOF
To easily connect buried pipes to each other even when the distance between buried pipe end parts of a pair of adjacent precast concrete walls is limited.SOLUTION: A joint member 30 of a precast concrete wall buried pipe, a first precast concrete wall 2 in which a first buried pipe 4 is buried, and a second precast concrete wall 2 'in which a second buried pipe 4 ' is buried are prepared; a joint pipe 6 is inserted into a second diameter-enlarged end part 22 so that a compression coil spring 7 is pushed into and accommodated therein, and then secured to prevent it from slipping out; the first precast concrete wall 2 and the second precast concrete wall 2 'are arranged so that a first protruding end part 10 and the second diameter-enlarged end part 22 face each other; the first protruding end part 10 and the second diameter-enlarged end part 22 are connected in a state that the joint pipe 6 secured to prevent it from slipping out is opened and pushed back by the compression coil spring 7.SELECTED DRAWING: Figure 1
【課題】隣接する一対のプレキャストコンクリート壁の埋設管端部間の距離が限られている場合であっても、容易に埋設管同士を接続できるようにする。【解決手段】プレキャストコンクリート壁内埋設管の継手部材３０と、第１埋設管４が埋設された第１プレキャストコンクリート壁２及び第２埋設管４’が埋設された第２プレキャストコンクリート壁２’を準備し、継手管６を、第２拡径端部２２に圧縮コイルバネ７を押し込んで収容するようにして挿入した上で抜け止めし、第１突出端部１０と第２拡径端部２２とが対向した位置になるように、第１プレキャストコンクリート壁２と第２プレキャストコンクリート壁２’とを並べ、抜け止めしていた継手管６を開放して圧縮コイルバネ７に押し戻された状態で、第１突出端部１０及び第２拡径端部２２を接続する。【選択図】図１
