The present invention relates to a soundproof wall installed on the side of the road to block noise, and more specifically, the inner surface of the soundproof wall as well as the outside of the inaccessible soundproof wall using a high-pressure water spraying station installed at the tip of the boom bent at multiple angles. It is possible to clean the soundproof wall neatly by spraying high pressure water in the state close to the side, and selectively remove the auxiliary boom to reduce the overall length of the boom to effectively clean the tunnel wall even inside the tunnel where the working radius is narrow. It relates to a soundproof wall cleaning device that can be parallel.

In general, soundproof walls are used for the purpose of blocking noise and are mostly installed on roadsides. Such soundproof walls have a sound absorbing material such as glass wool inside, and a plurality of sound absorbing holes for absorbing noise are formed on the outer circumferential surface thereof.

However, since the soundproof wall is composed of an opaque plate made of metal, when it is installed at a certain height on the side of the road, there is a disadvantage that the driver cannot see the outside view of the road while driving the road.

Such transparent soundproof walls have a problem of making aesthetic appearance when it is contaminated by rain or dirt, etc., so these soundproof walls must be cleaned regularly.

Conventionally, a cleaning vehicle equipped with a rotary brush or the like is used to clean the soundproof wall, but in this case, the brush is easily worn due to the characteristics of the soundproof wall formed with the uneven portion, but the outer surface of the soundproof wall is not accessible. Limited cleaning was possible on the inner side.

In other words, during the cleaning process, the inner and outer surfaces of the soundproof wall must be cleaned at the same time. However, in the case of the soundproof walls installed on the overpass and tracks, it is almost impossible to clean the outer surface of the soundproof wall because the vehicle cannot access the outer surface.

In order to solve this problem, there is a method of installing the soundproof wall in a rotatable state instead of a fixed state, and cleaning the soundproof wall temporarily while cleaning the outer surface. The shielding power to block is lowered, causing a cumbersome problem of rotating the sound insulation board during operation.
