Abstract
Although blasting is an effective method of fracturing rock mass, the method involves tremendous shock waves and noise. Due to recent increase in rock excavation near residential areas, there have been growing demands for alternative methods of excavation to avoid excessive noise pollution. A new static fracturing method of rock excavation and demolition of concrete structures using pressurized fluid was developed to satisfy such demands.
This paper describes the outline of fracturing machine and fracturing system used in the method, function check experiments of the machine and applicability of the method to rock slope excavation and demolition of top of concrete piles.
It is confirmed that the method shows sufficient function to fracture rock mass and concrete structures.
