压密灌浆(Compact Grouting)是美国独特的加固土层的新方法,它是由美国格雷夫(Craf)于1989年提出来的。尽管这一方法至今已有20年的历史,但是,在前10多年中,并未得到推广,仅在美国南部地区得到应用,那时仅作为修复补救措施。最近几年在应用压密灌浆的实践中,进一步认识到压密灌浆与传统的基础加固灌浆或其他补救方案相比,在经济性,易于施工和与建筑物干扰少等方面有着很大的优越性。如1982
Compact Grouting is a unique new method for strengthening soil in the United States. It was proposed by the United States in 1989 by Craf. Although this method has been in existence for 20 years, it has not been popularized in the first 10 years and it has only been applied in the southern United States. At that time, it was only a remedial measure. In recent years, in the practice of compaction grouting, it has been further recognized that compacted grouting has great advantages in economy, ease of construction, and less interference with buildings compared with traditional foundation grouting or other remedial solutions.
