Description

The present invention relates to a tunnel ceiling surface cleaning method and a tunnel ceiling surface cleaning device, and more particularly to a tunnel ceiling surface cleaning method and a tunnel ceiling surface cleaning device for cleaning the ceiling surface of a box culvert type railway tunnel.

For example, many box culvert type tunnels have been constructed on roads such as the Metropolitan Expressway and railway lines such as the subway, and many of them have been in service for more than 30 years. For this reason, various repair works are being carried out on the old box culvert type tunnel, including prevention of peeling of concrete pieces. As a repair work for a box culvert type road tunnel or railway tunnel, for example, when performing surface treatment work (ground adjustment work) by cleaning the inner wall surface of the tunnel, such surface treatment work by cleaning is performed for at least one lane. Since it is necessary to carry out while controlling road traffic while the road is in service, or to carry out at night when the railway line is out of business hours, it will be possible to work speedily, efficiently and in a short time. Is desirable.

Further, for example, if an attempt is made to manually clean the inner wall surface of a box culvert type tunnel using a known sweeping device, the work will be performed while the ceiling surface of the tunnel is facing upward. Not only is it a painful task, but it also requires a lot of labor and it is difficult to work efficiently. For these reasons, the applicant of the present application has developed a tunnel ceiling surface cleaning device that enables speedy and efficient cleaning of the ceiling surface of a box culvert type road tunnel. (See, for example, Patent Document 1 and Patent Document 2). According to the sweeping device of Patent Document 1 and the sweeping method of Patent Document 2, the tunnel ceiling surface sweeping device includes an outrigger portion, a gantry portion, a dry sweeper, a moving rail portion of the dry sweeper, and the like. The rails are loaded on the loading platform of the transport vehicle, and are appropriately moved by the transport vehicle to just below the cleaning point on the ceiling surface of the tunnel. In addition, at the cleaning point on the ceiling surface, after adjusting the pedestal part to be horizontal by the outrigger part, the moving rail part installed on the upper part of the pedestal part is adjusted so that it is arranged parallel to the ceiling surface, and it is a dry type. The ceiling surface is cleaned while moving the sweeper back and forth and left and right along the moving rail.
