DEMOLISHING METHOD OF CONCRETE STRUCTURE AND PLASMA SHOCK WAVE INJECTOR USED THEREFOR

PROBLEM TO BE SOLVED: To provide a demolishing method for a concrete structure capable of reducing energy consumption required for demolition of the concrete structure, miniaturizing a device and effectively demolishing it with a little energy in a short time. SOLUTION: In the demolishing method for a concrete structure 2, a part of internally existing reinforcements or steel frames is exposed out of the concrete structure 2 and shock waves simultaneously or stepwise generated by plasma discharging or blasting are imparted in two directions of the axial direction C and the direction D orthogonal to the axis to the same reinforcements 3 or the steel frame with every time interval.
