DEMOLITION METHOD OF TOWER-LIKE STRUCTURE
PROBLEM TO BE SOLVED: To provide a demolition method of a tower-like structure that readily prevents scattering of dusts, reduces frequency of use of heavy machinery, reduces labor for environmental measures in a surrounding, and enables efficient demolition work.SOLUTION: The following steps are executed in a demolition method of a tower-like structure: a vertical-direction cutout unit 40 is installed inside a chimney 10, the vertical-direction cutout unit having a vertical-direction injection nozzle 43 for injecting high pressure water W; the vertical-direction injection nozzle 43 is moved in the vertical direction while injecting the high pressure water W, to form a vertical-direction cutout part 51 penetrating through a wall body 11 of the chimney 10 in a thickness direction; then, a circumferential-direction cutout unit having a circumferential-direction injection nozzle is installed; the circumferential-direction injection nozzle is moved in the circumferential direction while injecting the high pressure water W to form a circumferential-direction cutout part penetrating through the wall body 11 of the chimney 10 in the thickness direction, thus forming a cutout part continuing from an opening at a top of the wall body 11; and a demolition piece in an area surrounded by the cutout parts is made to fall inside of the chimney 10.SELECTED DRAWING: Figure 5
【課題】塵埃の飛散を容易に防止できるとともに重機の使用頻度を低減できて、周辺環境対策にかかる手間を低減しつつ効率よく解体作業を行うことが可能になる。【解決手段】煙突１０の内部に高圧水Ｗの縦方向噴射ノズル４３を有する縦方向切込みユニット４０を設置し、高圧水Ｗを噴射しつつ縦方向噴射ノズル４３を縦方向に移動させ、煙突１０の壁体１１を厚さ方向に貫通した縦方向切込み部５１を形成した後、周方向噴射ノズルを有する周方向切込みユニットを設置し、高圧水Ｗを噴射しつつ周方向噴射ノズルを周方向に移動させ、煙突１０の壁体１１を厚さ方向に貫通した周方向切込み部を形成することで壁体１１の上部の開口から連続する切込み部を形成し、切込み部によって囲まれた領域の解体片を煙突１０の内部に落下させるようにした塔状建築物の解体方法を提供する。【選択図】図５
