Description of the Related Art There is a ductile cast iron pipe buried in the ground for piping such as water supply, and there is a deformed pipe as a joint for connecting the ductile cast iron pipe. The deformed pipe has, for example, the form shown in FIG. 5, and its inner surface is coated for anticorrosion and the like, and blasting is performed as a pretreatment. In general, the blasting process is performed by inserting a blast nozzle into a deformed pipe and ejecting a blast material such as a steel ball cut in half from a nozzle called a grit (see Examples).

2.5 degree bend, 11.25 degree bend, 5.625 bend 6
There are several types and structures, such as NS type, SII type, A type, K type, etc., and the number of dedicated support jigs corresponding to these various shaped tubes W is very large. In addition, the jig must be replaced every time the blast processing of the various shaped pipes W is performed, and the replacement work is troublesome.

ある。SUMMARY OF THE INVENTION In order to achieve the above object, the present invention first supports a rotary table. Since the blast nozzle is inserted straight into the deformed pipe, if the deformed pipe is a curved pipe, turn the rotary table so that the receiving port and the insertion port of the deformed pipe face the nozzle respectively to facilitate the insertion. To get it.

This is because, in the case of a curved tube, unless the intermediate portion is supported, the intermediate portion rotates downward, and the tube axis cannot be positioned substantially on a horizontal plane. At this time, the three-point support portion is set so that the pipe axis is substantially horizontal, and the axial center of the receiving portion and the insertion portion is substantially equal to the table diameter even when the table is rotated. In the direction, the nozzle can be inserted. Further, the support of the receiving portion and the insertion portion is prevented from rolling as fitting.

In, on the rotary table,
The supporting member of the receiving portion of the deformed tube, the supporting member of the insertion portion, and the supporting member of the intermediate portion are provided along the radial direction of the table, and the deformed tube mounted on each member is removed from the upper surface. A member for holding down and fixing to each member is provided, and the supporting member for the receiving portion is formed with a V-shaped concave portion in which the receiving portion is fitted from above, and the supporting member for the inserting portion is provided with the insertion member. The mouth has a concave portion fitted from above and is movable and fixable in the circumferential direction of the table according to the shape of the deformed pipe, and when the receiving port and the insertion port are supported by the support member, The axis of the receiving portion and the insertion portion are substantially the same height, and the deformed pipe is in contact with the intermediate support member from above, and the contact height is the intermediate portion of the deformed pipe. So that the height of the center of the shaft is substantially the same as the height of the center of the receiving portion and the insertion portion. It can be adopted going on configuration.
