虽然爆破是破碎岩体的有效方法，但该方法会产生巨大的冲击波和噪声。由于最近住宅区附近岩石开挖的增加，对替代开挖方法以避免过度噪音污染的需求不断增长。为了满足这种需求，开发了一种新的利用加压流体进行岩石开挖和混凝土结构拆除的静态压裂方法。本文介绍了该方法所使用的压裂机和压裂系统的概要、该机的功能检验实验以及该方法在岩质边坡开挖和混凝土桩顶拆除中的适用性。证实该方法对岩体和混凝土结构具有足够的破碎功能。
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.
