Chemical Grouting And Effect Checking On Rocky Foundation

As a kind of technology, chemical grouting has widely been applied in many fields such as civil engineering, city planning, hydraulic and power, transportation and energy, underground building etc. Currently, it has become a disciplinary that aggregated with high molecule chemistry, geotechnical mechanics, mechanic, automation technology, computer technology together. Based on study achievement, this paper simply has introduced basic contents of chemical grouting, and probed intensively grouting theory, and concluded equations relating on chemical grouting, and introduced effect check ways after grouting on rocky foundation. According to several engineering examples, this paper has probed and contrasted quantitatively the effect of chemical grouting. Based on Longyang canyon and Lijia canyon, the author has concluded that chemical grouting attained satisfactory effect on strengthening fault so long as choose suitable grout ratio. Based on Wanjiazhai engineering^ the author has assayed the cause that the effect wasn't reasonable, that has the order before grouting and quantity during grouting etc. Therefore, some reasonable proposals have been tabled in relations to the grouting methods and quantity methods. As a whole, from several examples we have known that we must research varying grout and engineering geological conditions of strengthened rock because of rock existence environment hi order to attain anticipatory aim, or else, you would not have been success even though depleted a lot of people and substance.
