STRUCTURE FOR DEMOLITION WORK AND DEMOLITION WORK METHOD

摘要

PROBLEM TO BE SOLVED: To provide a structure for demolition work which securely prevent powder dust generated by demolishing a structure to be demolished from scattering to peripheral environment, is easy in the construction and removal, and has a high dust removal effect.;SOLUTION: The structure for demolition work comprises: a powder-dust shielding building constructed by surrounding the whole structure to be demolished; a suction port arranged on a side wall of the powder-dust shielding building; a suction means for being connected to the suction port through a dust removing means, sucking out the air inside of the powder-dust shielding building, and making negative pressure inside of the powder-dust shielding building; a slit-like opening arranged on a side wall other than the side wall in which the suction port is arranged; a shielding sheet for negative pressure adjustment for covering the whole slit-like opening from the inside of the powder-dust shielding building and opening depending on the negative pressure of the inside of the powder-dust shielding building; and a negative-pressure monitoring means for monitoring the negative pressure inside of the powder-dust shielding building, so as to make the inside of the powder-dust shielding building negative against the outside.;COPYRIGHT: (C)2010,JPO&INPIT
