Inclined Chimney Small Angle Incision Directional Blasting Demolition Technology
In order to safely demolish 42m inclined brick-concrete structure chimney with directional blasting technology,a small angle incision of 180° was determined through theoretical mechanics calculation and analysis,combined with engineering practice.Through the principle of force synthesis,the blasting center line and deviation correction angle of inclined chimney are calculated accurately.By using the small angle incision directional blasting demolition technology,the inclined chimney can fall to the ground according to the reverse tilt after rectification,and the blasting effect is good,which verifies the feasibility of the inclined chimney demolition by small angle incision directional blasting.
