注浆工程属隐蔽工程。注浆前岩、土体的性状探测对于制定正确的注浆设计、选择合理的注浆参数、防止浆液过量耗损等均有重要的作用。而对注浆后的施工质量评价、效果鉴定等,对于改进注浆工艺、设备,完善注浆技术,避免工程质量事故等,则更有意义。目前注浆工程常用的主要检测手段是抽水或压水试验、取芯分析和注浆施工记录分析等。这些方法是比较可靠有效的也是必要的,但耗时较长、工作量较大,且不能直观地反映出注浆前后岩土体性状的情况,因
Grouting works are concealed projects. Pre-grouting rock, soil properties detection for the development of the correct grouting design, selection of a reasonable grouting parameters, to prevent excessive wear and tear and so have an important role. The grouting after the construction quality evaluation, the effect of identification, etc., for improving the grouting process, equipment, improve grouting technology, to avoid engineering quality accidents, more meaningful. At present, the main testing methods commonly used in grouting engineering are pumping or water pressure test, coring analysis and grouting construction record analysis. These methods are more reliable and effective and necessary, but they take a long time and require a lot of work load. They can not directly reflect the characteristics of rock and soil before and after grouting
