Blow counts are calculated beforehand. In case the blow count is different in the sector, there’s likely an issue. Here's prevalent troubles and answers associated with blow count:
Driving method challenges can be connected with very low hammer effectiveness or cushion that is definitely too comfortable. The soil might have greater power, increased damping ration, or larger soil quakes than Original tests predicted.

If Earlier mounted piles transfer laterally when new piles are driven, soil displacement may be the possible culprit. Nonetheless, the failure of soil within an adjacent slope can be the result in.
Compaction grouting or jet grouting could be completed under The underside from the pipe whether it is surrounded or coated by soil. Additionally, the pipe is usually partially withdrawn although getting crammed with grout which is pressured to supply a bond zone.
Wherever the blow count is much reduce than anticipated, assessment the soil borings. If there is absolutely no indicator of soft layers, the pile might be ruined beneath the grade.

If you are however here owning a concern, compute the stress over the pile head. Reduce the hammer stroke for small blow counts; raise for high blow counts. Even so, you may have to select another hammer – even a different pile kind.
Other employs of micropiles are to supply structural support, underpin foundations to eliminate settlement, boost soil and slope security, and transfer masses to a secure soil strata.
The difficult aspect of working with soil presents many different troubles that may be anticipated. The project’s possibility mitigation prepare can look at very likely issues to generally be encountered. Options can be A part of contingency preparing – preventing Value overruns.
