Bulb grouting
WebApr 26, 2012 · Preliminary results indicate that the grout bulb development is a function of the overburden pressure, injection rate, and grout composition. When similar volumes of grout are injected, grouts with smaller clay content developed into smaller grout bulbs than greater clay content grouts. WebThe grout is then injected as the pipe is slowly removed in lifts, creating a column of overlapping grout bulbs. The expansion of the low mobility grout bulbs displaces surrounding soils. Compaction grouting increases the density, friction angle, and stiffness of surrounding granular soils.
