PROBLEM TO BE SOLVED: To provide a culvert drain pipe laying apparatus capable of continuously supplying a hydrophobic material on a culvert drain pipe at the same time while laying the culvert drain pipe in soil, and accurately laminating the thickness of each hydrophobic material.SOLUTION: The culvert drain pipe laying apparatus 2 laminating a first hydrophobic material and a second hydrophobic material on the culvert drain pipe includes a horizontal transfer conveyor receiving the first hydrophobic material from a first hydrophobic material hopper 7, and an excavating body 11 disposed at the lower part of the horizontal frame 3 to form a vertical ditch. The rear part of the excavating body 11 is provided with a culvert drain pipe guide part 15 guiding the culvert drain pipe to deliver it into the vertical ditch, and the carry-out side of the horizontal transfer conveyor is connected to a cylindrical hydrophobic material supply chute 19. A vertical transfer conveyor 20 vertically conveying the hydrophobic material downward is arranged in the hydrophobic material supply chute 19. A hydrophobic material discharge port 21 of the hydrophobic material supply chute 19 is provided with a thickness adjusting plate 22 of the first hydrophobic material, and a second hydrophobic material discharge port 25 of a second hydrophobic material hopper 8 is provided with a thickness adjusting plate 26 of the second hydrophobic material.COPYRIGHT: (C)2011,JPO&INPIT【課題】土中に暗渠排出管を敷設しつつ、その上に疎水材を同時に連続的に供給して各疎水材の厚みを正確に積層可能な暗渠排水管敷設装置を提供する。【解決手段】暗渠排水管に第1の疎水材と第2の疎水材を積層していく暗渠排水管敷設装置2において、第1疎水材ホッパー7から第1の疎水材を受けて水平搬送コンベヤが設けられ、水平フレーム3の下部に、縦溝を形成する掘削体11が配設され、掘削体11の後部に暗渠排水管を案内して縦溝内に繰り出す暗渠排水管案内部15が設けられ、水平搬送コンベヤの搬出側は、筒状の疎水材投入シュート19に接続され、疎水材投入シュート19には疎水材を下方へ垂直搬送する垂直搬送コンベヤ20が配置され、疎水材投入シュート19の疎水材排出口21に第1の疎水材の厚さ調整板22が設けられ、第2疎水材ホッパー8の第2疎水材排出口25に第2疎水材の厚さ調整板25が設けられている。【選択図】図3
