The invention relates to dust-falling equipment for tunnel construction, in particular to movable type dust-falling equipment for tunnel construction. The movable type dust-falling equipment has the advantages that moving is convenient, the dust-falling effect is good, and the energy saving effect is achieved. The movable type dust-falling equipment comprises a bottom plate and the like; the bottom plate is in a rectangular shape, wheels are mounted around the bottom of the bottom plate, the right side of the top of the bottom plate is connected with a pushing handle, and driving devices are mounted on the front side and rear side of the right side of the bottom plate; and driving parts on the driving devices are connected with the outer sides of the wheels on the right side, the right side of the top of the bottom plate is connected with a bracket, and the bracket is located on the left side of the pushing handle. According to the movable type dust-falling equipment for tunnel construction, the wheels are driven to roll through the driving devices and a dust-falling device is driven to work, flying dust produced by tunnel construction is sprayed and covered, electricity is provided to the driving parts through an electricity generating device, and the effects of being convenient to move and capable of saving energy are achieved accordingly.
