... and remains in a homogeneous mass that displaces the surrounding soils through a distinct grout-soil interface. This results in a controlled densification of the surrounding soils. The grout material may be formed as globular bulbs injected into discrete soil zones or as compaction grout piles. The compaction...

... ABSTRACT Intermittent compaction grout piles were used to improve foundation soils of Tokyo International Airport against liquefaction at the intersection area of the two runways A and B. The compaction grouting works were performed in five working stages. The grouting works of the fifth stage...

... to investigate the effectiveness of treatment by compaction grout piles. The test consisted of eighty-seven compaction grout piles injected in three cases of different pile diameters and spacings. The results of treatment by the three cases are comparatively discussed for the shallow injections and significant...

... technical understanding of the deformation and treatment mechanisms. This paper presents analyses of the results of a field test on compaction grout piles, with emphasis being given to the effect of soil compressibility on the grouting performance. The test consisted of thirty-seven compaction grout piles...

... ABSTRACT Although compaction grouting has been developed empirically with little technical understanding of the associated grouting mechanisms and improvements, its applications are numerous. Compaction grout piles, usually formed by a volume-controlled staging up method, have been extensively...
