To prevent intrusion of sediment to a bottom part of a groove formed by excavation and secure a predetermined cross section, and efficiently lay a water suction pipe and perform filling with a hydrophobic material.SOLUTION: A culvert formation device for drainage includes an excavating implement 10, a water absorption pipe guide part 20, and a hydrophobic material filling part 30, wherein a shank 13 forming the excavating implement has a blade 11 and a culvert drilling body 12 and has a sediment removal part 15 provided on a front side upper end, a rear end is formed so as to be inclined toward a front lower side, and marks 16a to 16d displaying a height of a groove are provided on a rear side face. The water absorption pipe guide part has: a pipe insertion path 24 which communicates with a pipe insertion port 21 opened at a position of the sediment removal part on the upper end of the shank and extends toward the rear side; and a pipe delivery port 23 that communicates with a lower end of the pipe insertion path through an enlarged part 22. The hydrophobic material filling part has a hydrophobic material charging hole 31 that is continuously arranged in an auxiliary hopper 4A and is opened from the vicinity of the rear end of the shank toward the pipe delivery port side.SELECTED DRAWING: Figure 2
【課題】掘削により形成された溝の底部への土砂等の侵入を阻止して所定の断面を確保し、吸水パイプの敷設と疎水材の充填を効率よく行えるようにすること。【解決手段】掘削具１０、吸水パイプガイド部２０、疎水材充填部３０を具備する排水用暗渠形成装置において、掘削具を形成するシャンク１３は、ブレード１１と暗渠穿孔体１２を有し、前方側上端に、土砂排除部１５が設けられ、後方端部が、前方側下方に向かって傾斜状に形成され、後方側面に溝の高さを表示する目印１６ａ～１６ｄが設けられる。吸水パイプガイド部は、シャンクの上端部の土砂排除部の位置に開設されるパイプ挿入口２１に連通して後方側に向かって延びるパイプ挿通路２４と、パイプ挿通路の下端部に拡開部２２を介して連通するパイプ送出口２３を有する。疎水材充填部は、補助ホッパ４Ａに連設され、シャンクの後端近傍からパイプ送出口側に亘って開設される疎水材投入穴３１を有する。【選択図】 図２
