the Pressure Grouting Lining Method
-
摘要: 提出了一种解决爆炸空腔支护和防渗的新方法——压力注浆衬砌技术。探讨了压力注浆衬砌技术的基本机理,试验选用了BR防水剂增加抗渗能力,确定了基本的注浆参数,并进行了注浆衬砌支护对比试验。试验表明:注浆衬砌支护是解决支护和防渗较为可行的新方法。Abstract: Puting forward a pressure grouting lining method for shoring and preventing seepage in blasted cavity soils, discussing its essential mechanism,using the BR preventing seepage to reduce seepage rate,determining the basic grouting parameters,through the contrast test,its feasibility is proved.
