Grout can also be pumped from the centre of the bearing plate where it spreads to the outside equally on all sides. A peristaltic pump is used for resin grouts and a diaphragm or worm pump for cement grouts. Alternatively, for large grouting areas, a grout lance is placed through the gap to the other side and withdrawn slowly as pumping proceeds.
Cause A – GROUT DISINTEGRATION. Very often when the grouting is not up to specification the vibration from the mill tends to disintegrate the grouting. In most instances the disintegration starts between the sole plate and the top surface of the grouting near or at the vertical centerline of the mill.
Vertical steel pipes were driven with the pile driver down to the bedrock interface around the outside of the sheet pile perimeter and a thick cement grout was injected to compact disturbed soil conditions and create stable lenses of cement grout at the overburden/rock interface.
