DRAINAGE PIPE BURYING DEVICE AND DRAINAGE PIPE BURYING METHOD
To remove a corrugated pipe from a buried head simply by pulling the buried head out of the ground.SOLUTION: A drainage pipe burying device comprises a first arm 10 connected to a traction mechanism 2, provided rearward and movable in the vertical direction, a second arm 12 provided downward from the first arm, a buried head 20a provided at a lower end of the second arm, the front end of which is closed, the rear end of which is opened by an opening 24a, and having a tubular portion 21a in which one end of a corrugated pipe 3 is mounted on the opening. The opening comprises an upper arc portion 25a extending rearward, one or more upper claw portions 26a protruding in the inner peripheral direction from the upper arc portion, a first lower arc portion 27a located relatively in front of the upper arc portion, and one or more first lower claw portions 28a protruding in the inner peripheral direction from the first lower arc portion.SELECTED DRAWING: Figure 1
【課題】埋設ヘッドを地中から引き上げるだけで埋設ヘッドから波形管を取り外すことができるようにする。【解決手段】牽引機構２に連結され、後方に向かって設けられ上下方向に可動可能な第１アーム１０と、前記第１アームから下方に向かって設けられる第２アーム１２と、前記第２アームの下端に設けられ、前端が閉じられるとともに後端が開口部２４ａによって開口され、前記開口部に波形管３の一端が装着される管状部２１ａを備える埋設ヘッド２０ａと、を備え、前記開口部は、後方に向かって延伸される上円弧部２５ａ、前記上円弧部から内周方向に突出した１つ以上の上爪部２６ａ、前記上円弧部より相対的に前方に位置する第１下円弧部２７ａ、及び前記第１下円弧部から内周方向に突出した１つ以上の第１下爪部２８ａを備える。【選択図】図１
