Design and construction of hydraulic blasting demolition of high-strength pre-stressed pipe piles
Underwater concrete demolition and steel bar cutting usually require workers to dive,which is highly dan-gerous,time-consuming and costly.In order to solve the above mentioned problems,an introduction is made on the hydraulic blasting demolition method of high-strength pre-stressed pipe piles which is adopted by a shipping com-pany,including the technical principles,demolition layout,blasting conditions,parameter design,blasting plan se-lection etc.This method has significant advantages in safety,controlling flying rock,improving construction efficien-cy,shortening construction period and saving cost.
