を特徴とする異形管の製造方法に存する。 A pipe with a resin mortar layer of irregular shape on the outer surface is
For example, it is useful as a power cable protection pipe that is buried underground using a multi-stage construction method. This was inconvenient because there was no suitable continuous manufacturing method available for manufacturing circular tubes. The present invention was made for the purpose of solving the conventional drawbacks as described above, and the gist thereof is to provide a core mold that rotates in the circumferential direction and moves in the axial direction, and a core mold that moves in the axial direction while rotating in the circumferential direction. The molding material is supplied between a rotatable roller that is in contact with the tensioned rotating cam and is provided so that the gap between it and the core mold changes periodically, thereby forming a layer of molding material with an irregular outer surface around the core mold. The present invention relates to a method for manufacturing a deformed tube, characterized by forming a deformed tube.
以下、本発明を実施例により図面を参照して説
明する。 Hereinafter, the present invention will be explained by way of examples with reference to the drawings.
１は芯棒の外周面に巻きつけられた帯状の厚紙

により、その外面と芯型１の外面との間に周期的
に周隙が変化するようにされている。 2 is a forming roller, which is located on the side of the core mold 1 so as to be parallel to the axial direction of the core mold 1, and is placed on a movable table 3 provided in a horizontal direction perpendicular to the axis of the core mold 1. Fixed. The roller 2 is pulled from the wall in the direction away from the core mold 1 by a tension mechanism 4 such as a spring, and contacts the surface of the rotating cam 5 at a certain point on the side opposite to the core mold 1, and the cam is Due to rotation, the circumferential gap between the outer surface and the outer surface of the core mold 1 changes periodically.
周方向に回転しつつ軸方向へ移動する芯型１の
まわりに適宜離形材６を巻き、芯型１とローラー

を通して硬化させた後、芯型１を抜去して異形管
を連続的に製造する。 A release material 6 is appropriately wrapped around the core mold 1 that rotates in the circumferential direction and moves in the axial direction, and a molding material 7' such as resin mortar is placed in the periodically changing gap between the core mold 1 and the roller. is supplied to form a molding material layer 7 with an irregularly shaped outer surface around the core mold 1, and then heated to a curing furnace 8.
After passing through and curing, the core mold 1 is removed to continuously manufacture irregularly shaped tubes.
叙上の如く、本発明異形管の製造方法は、周方
