REMOVAL METHOD AND REMOVAL DEVICE OF ASBESTOS-CONTAINING LAYER
To remove an asbestos-containing layer formed on a surface of a structure without providing a shield space, without necessity for a worker to wear a protective clothing, in a shorter time than the time required in a conventional one.SOLUTION: A removal device D of an asbestos-containing layer L includes laser irradiation means 1 and gas injection means 2. The laser irradiation means 1 irradiates the asbestos-containing layer L with laser light to melt the asbestos-containing layer L. The gas injection means 2 includes a first nozzle 22 that injects a gas to an irradiation spot SP of laser light and removes a molten material from a surface of a structure S, and a second nozzle 23 that eliminates a flying object including a molten material jetted onto an optical path of the laser light from the optical path. The irradiation spot SP of the laser light is movable relative to the structure S.SELECTED DRAWING: Figure 1
【課題】構造物の表面に形成されたアスベスト含有層を、遮蔽空間を設けることなくまた作業者が防護服を着用することなく従来よりも短時間で除去すること。【解決手段】アスベスト含有層Ｌの除去装置Ｄは、レーザー照射手段１と気体噴射手段２とを有し、レーザー照射手段１はアスベスト含有層Ｌにレーザー光を照射してアスベスト含有層Ｌを溶融し、気体噴射手段２は、レーザー光の照射スポットＳＰに気体を噴射して構造物Ｓの表面から溶融物を除去する第１ノズル２２と、レーザー光の光路上に噴出した溶融物を含む飛翔物を光路上から排除する第２ノズル２３とを備え、レーザー光の照射スポットＳＰは構造物Ｓに対して相対移動可能である。【選択図】図１
