First, when the broken hole D penetrating the rubber undulating dam 3 is in a state of being formed, the uppermost (outer) rubber layer element centering on the broken hole D as shown in FIG. The surroundings are cut out in order from 32a using a cutter knife, and a patch receiving recess 35 for repair is formed. The rubber layer element 32a, the rubber layer element 32b, and the rubber layer element 32c are sequentially cut downward (inside the tube main body 30), so that the area to be cut becomes smaller. It is described that the receiving recess of the repair patch is formed in a concave staircase shape in a sufficiently wide range with respect to the damaged portion of the tube body of the undulation weir. Accordingly, in some cases, the rubber layer element 32c may be filled with a rubber filler or the like without intentionally opening the damaged hole D.

<3. Preparation of repair patch>
In this way, the patch receiving recess 35 is formed in the repaired site, and the repair patch 36 is prepared so as to match the patch receiving recess 35. For example, when the patch receiving recess 35 is formed in a concave staircase shape over three layers, the repair patch 36 is prepared in three stages according to the thickness of each patch. In this case, it is preferable that the end face to be cut to form the patch receiving recess 35 has a somewhat tapered angle so as to open upward. After processing according to the repair site in this way, an adhesive is applied to the entire contact surface of the patch receiving recess 35 with the repair patch 36, and depending on the adhesive, this may be appropriately dried for the next operation. Prepare. The broken hole D remaining in the lowermost rubber layer element 32d may be left open as it is, or may be filled with uncured rubber or the like.

<4. Excitation press>
In such a state, the repair patches 36 are sequentially fitted into the patch receiving recesses 35 and subjected to vibration pressing by a vibration device. Of course, it is preferable to perform the vibration pressing for each layer. In this case, when the patch receiving recess 35 is smaller than the rolling pressing attachment device 1, the pressing is performed using a simple rammer-like vibration attachment.
The pressure contact work using the rolling pressing attachment device 1 is performed by using the rolling of the pressing roller 15 while driving the vibrating drill body 2 to transmit the vibration to the rolling pressing attachment device 1. Adhesion is promoted while moving the surface to be moved.
At this time, since the pressing roller 15 is provided in the present invention, for example, when the rolling pressing attachment device 1 is operated so as to move in a certain direction from the end portion, the pressing roller 15 is bitten in the rubber coating layer. Since the received air is pressed while being pushed to one end, the pressed state can be obtained more reliably.

<5. Actual work mode>
In the preparation stage of the rolling pressing attachment device 1 of the present invention, the connecting rod 13 is first attached to the vibration chuck 23 of the vibration drill body 2 and then the rolling pressing attachment device, assuming that the connecting rod 13 is separated. 1 is described in the order of taper fitting, but when actually connected to the vibration drill body 2, the attachment connecting portion 130 of the tapered connecting rod 13 and the tapered connecting hole of the roller support frame 10A are used. The strong fitting with 120 is promoted, and the connecting rod 13 is substantially raised from the connecting portion 12 of the rolling pressing attachment device 1 and attached.
Therefore, in subsequent operations, the rolling pressing attachment device 1 and the connecting rod 13 are often handled in an integrated state. Of course, both may be fixed in advance by welding or the like.

  In such a vibration pressing operation by the rolling pressing attachment device 1, since the absorber layer 14 is formed over the frame main body 10 and the connection portion 12, the vibration drill main body 2 is attached to the frame main body 10. Excessive vibration transmitted from the vehicle can be avoided and generation of noise can be prevented. Further, when the absorber layer 14 is in contact with the roller shaft 16, excessive vibration transmission to the pressing roller 15 is suppressed, and noise that tends to occur in the pressing roller 15 can be prevented.

  Further, the rolling pressing attachment device 1 may be provided with a weight member W on the frame body 10. In this case, the weight member W absorbs fine vibrations and on the other hand amplifies vibrations. Also do. As a result, strong vibrations are effectively transmitted to the working member.
