PROBLEM TO BE SOLVED: To provide an investigation jig of gradient of piping and investigation method for gradient of piping which can confirm the vertical degree of piping by using only space of one side of the piping without inserting a checking/measuring devices in the piping.;SOLUTION: In a tank preparative nozzle 17, a laser emitter 41, a support 33 fixed in the piping 13 and hanging and moving the laser emitter 41, and a jig 27 for investigating the gradient of piping having a inclined transparent plate 32 placed on the upper end of a single pipe 31 with a transparent plate are provided. The jig 27 for investigating the gradient of piping properly moves the light source position of the laser emitter 41 by using a movable stage 45 moving in parallel on a beam 33 placed on the single pipe 31 with transparent plate, a rotation stage 47 rotationally moving on the moving stage 45 and a rotation rod 49 and a laser light 51 is irradiated vertically downward from the laser emitter 41. By observing the reflection light 53 of the laser light 51, the range 63 where the degree of perpendicularity of the piping 13 is kept is grasped.;COPYRIGHT: (C)2007,JPO&INPIT
