A rail-shaped guide 6 is provided in the gate frame 3 parallel to the wall surface 2a of the sound insulating wall body 2. This guide 6
are provided parallel to both the inner and outer wall surfaces 2a of the wall 2, and for example, when the wall 2 is curved, the guide 6 is also curved in the same way.

Reference numeral 7 in the figure indicates a cleaning device movably installed on the guide 6. As shown in FIG. A flexible cover 9 is attached, a cleaning roller 10 made of a sponge roll, a brush roll, etc. is rotatably provided inside the cover 9, and the cleaning roller 10 is connected to a driving electric motor 11 attached to an end of the cover 9. The cleaning roller 10 had its circumferential surface located on the opening surface of the cover 9, and an end of a cleaning water injection hose 12 was connected to the cover 9 via a spray nozzle 19, and an end of a suction hose 13 was connected to the cover 9.

The gate frame 3 has an auxiliary frame 3a on the side of the road 1 to increase the width of that side, and a cleaning liquid tank 14, a waste liquid tank 15, and the drive device 18 are installed inside this auxiliary frame 3a, so that the center of gravity is on this side. Position it to the side. Further, the cleaning liquid tank 14 is connected to the injection hose 12 via a drawing pump 16, and the waste liquid tank 15 is connected to the suction hose 13 via a suction pump 17.

By the way, various engagements between the guide 6 and the cleaning device 7 can be considered. For example, if guide 6 is easy,
The cleaning device 7 may be provided with a gear meshing therewith, or the guide 6 may be a chain, and the base of the cleaning device may be attached to this so that the cleaning device 7 moves as the chain moves. In any case, the driving force for moving the cleaning device 7 can be provided with its own electric motor or the driving device 18 for traveling can be used.
