棄物処理車で処分場に搬送するようにしている。In the above method of spraying refractory material, a part of the refractory material sprayed from the nozzle toward the steel frame falls and accumulates on the floor surface.
This needs to be cleaned. Cleaning work on fireproof material (generally called fallen cotton) that has fallen on the floor surface can be done, for example, in the evening of the spraying work by collecting dust and sweeping it with a broom and putting it in a bag such as a plastic bag. When a certain amount has accumulated, they are transported to a first-floor or underground working base using a construction elevator or the like, and then transported to a disposal site by an industrial waste disposal vehicle.
