CULVERT PIPE LAYING DEVICE
To provide a culvert pipe laying device capable of simultaneously performing formation of a drain groove and laying of a culvert pipe, while maintaining a structure of a farm field.SOLUTION: A culvert pipe laying device comprises: a culvert pipe guide part 15 guiding a culvert pipe toward a bottom of a groove formed in a groove forming part 13; and a cylindrical filter material filling part 17 inserted in the groove behind the culvert pipe guide part and filling a filter material in the groove above the culvert pipe laid in the bottom of the groove. The groove forming part comprises: a sediment scooping part 27 scooping upward sediment in a part forming at least a lower half part of the groove to be formed; and a cutting part 28 sequentially connected to the sediment scooping part and expanding the sediment scooped by the sediment scooping part to both sides in a width direction. The sediment scooping part comprises an arc curved surface 30 in which an upper end is located behind a lower end on a front part side in a groove forming direction, and is provided at a position which does not exceed a height position of a rear end part RH of the lower end of the filter material filling part to allow adequate maintenance to be carried out.SELECTED DRAWING: Figure 5
【課題】圃場の構造を維持しながら排水溝の形成と同時に暗渠管を敷設することが可能な暗渠管敷設装置を提供する。【解決手段】暗渠管敷設装置は、溝形成部１３で形成した溝の底部に向けて暗渠管をガイドする暗渠管ガイド部１５と、該暗渠管ガイド部の後方で溝内に挿入され、溝の底部に敷設された暗渠管の上方の溝内に疎水材を充填する筒状の疎水材充填部１７とを備え、前記溝形成部は、形成する溝の少なくとも下半部を形成する部分の土砂を上方に掻き上げる土砂掻き上げ部２７と、該土砂掻き上げ部に連設され、土砂掻き上げ部で掻き上げた土砂を幅方向両側に押し拡げる切削部２８とからなり、前記土砂掻き上げ部は、溝形成方向前部側の下端に対して上端が後方に位置した円弧曲面３０を有し、疎水材充填部の下端後端部ＲＨの高さ位置を超えない位置に設けられることにより適切な整備ができる。【選択図】図５
