DEMOLITION OF HIGHRISE'S FOUNDATION PILE BY CONTROLLED BIASTING

The paper introduces the demolition of highrise's foundation pile by controlled blasting.The amount of explosive can be controlled to match the breaking energy through the selection of blasting plan,determination of blasting parameters,application of blasting network and safety measures,so as to reduce the scattering stones and vibration and guarantee the safety.The residual pile heads are not damaged and the reinforcement bars are not snapped off,attaining the expected blasting performance and satisfying the construction requirements.
