本発明は、縮径部分を有する管内において、ライニング
用や通線用の弾性の物体を流体圧により移動させる管内
での物体送り方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for feeding an object within a pipe, in which an elastic object for lining or wire passage is moved by fluid pressure within a pipe having a diameter-reduced portion.
従来、第３図（イ）に示すように、管（１）の−端部か
ら物体（３）を入れて、その一端部に送風機（１０）を
接続し、送風機（１０）による加圧のみで物体（３）を
移動させていた。Conventionally, as shown in Fig. 3 (A), an object (3) is put into the - end of the pipe (1), a blower (10) is connected to one end of the tube, and pressure is applied only by the blower (10). was moving object (3).
しかし、第３図（ロ）に示すように、縮径部（１ｃ）に
おいて背圧により物体（３）が管（１）に強く押付けら
れる状態に変形し、殊に縮径が大きいと、物体移動が困
難あるいは不可能になる危険性があった。However, as shown in Figure 3 (B), the object (3) is deformed to a state where it is strongly pressed against the tube (1) due to the back pressure at the reduced diameter part (1c), and if the reduced diameter is particularly large, the object There was a risk that movement would be difficult or impossible.
本発明の目的は、たとえ縮径が大きくても、縮径部にお

動させることにあり、その作用効果は次の通りである。The characteristic means of the present invention is to move an object by fluid pressure inside a pipe whose diameter is reduced, by inserting the object from one end of the pipe, connecting the discharge path of a pump to the one end, and A suction passage of a pump is connected to the other end of the pipe, and the object is moved to this side of the diameter reduction part by fluid pressure, and at least when the object passes through the diameter reduction part, the inside of the pipe is moved by the suction passage. The purpose is to reduce the diameter of the object by reducing the pressure and applying a suction force to the object, and then move the object to the other end of the pipe using fluid pressure, and its effects are as follows. It is.
物体が縮径部を通過する時に、管内のうち物体の前方側

に縮径変形させることができ、第３図（ロ）に示す従来
の不都合な現象を確実に防止でき、物体の締径部通過を
円滑に実現できる。When the object passes through the diameter reduction section, the pressure in the front side of the object inside the tube is reduced and a suction force is applied to the object, so that the object can be deformed smoothly into diameter reduction, as shown in Fig. 3 (b). The conventional inconvenient phenomenon described above can be reliably prevented, and objects can be smoothly passed through the tightened diameter section.
その結果、ライニングや通線のための弾性の物体を、た
