岩石及混凝土的破碎和拆除以往都是采用炸药、机械或人工的方法。人工凿除费时费工,劳动强度大,机械拆除往往机械损耗严重,噪声大。费用昂贵;目前广为采用的控制爆破方法虽然有很多优点,但由于炸药在远输、保管使用方面都有很多不安全因素,特别在繁华的市区和环境复杂的施工地点有不少问题是很难处理的。近两年国内研制出一种新型破碎材料 Rock and concrete crushing and demolition used to be explosives, mechanical or manual methods. Manual chiseling time-consuming and laborious, labor-intensive, mechanical disassembly is often a serious mechanical loss, noise. Costly; currently widely used method of controlled blasting, although there are many advantages, but because of the long-distance transport of explosives, the use of storage has many unsafe factors, especially in the bustling urban areas and complex construction sites have many problems Hard to deal with. The past two years developed a new type of broken material
