Mistakes to Avoid While Approaching Pile Foundation Construction!
Pile driving is often a cost-effective and time-effective way to get piles into the earth. But because you work with soil and other hidden elements on Earth, there's an unknown element, and things don't always go like they were scheduled. Whether you drive concrete, steel or timber batteries, there are a number of prevalent issues faced by hand piling specialist.
Not surprisingly, driving problems are usually linked to adverse or unexpected conditions, leading to piling damage, hammer-pile alignment problems and other problems. In many situations, it helps the specialist to detect the most likely cause of the problem by stopping work, testing, revisiting boreholes or calculations, and inspecting the equipment.
Blow Count Is Above Pile Penetration Requirements:
Soil assessment should correctly predict the number of blows necessary in order to move a pile into its intended depth and suggests an issue with either the driving scheme, the soil or both when the amount of blows is significantly greater than anticipated.
Confirm that the pile is drivable enough and that the driving scheme matches the pile type. Check that the hand piling specialist control system operation is in conformity with the manufacturer's rules if the battery and driving system is properly matched.
Piles Are Driving Significantly Deeper Than Estimated:
If the piles drive significantly deeper than expected, they can be caused by a low driving resistance of the soil or by better driving efficiency. Ask hand piling specialist to Conduct restricted tests to assess changes in soil strength after a suitable waiting period.
Check Driver Efficiency and Limit Ability:
Using dynamic measurements when the last capacity based on a restricted blow count is still small. The soil circumstances likely are weaker than expected if the drive system output is as expected and the capacity restricted is small. Fundamental piles will likely have to be driven deeper than initially estimated, or extra load-supporting piles are needed. To recognize the appropriate design modifications, contact the engineer/designer from hand piling specialist.
Abruptly Change or Decrease the Blow count for the Piling Group:
If you discover that the blow count changes or reduces unexpectedly, inspect the soil circumstances with the use of borings first. If a weathered profile does not show borings above the base/bearing layer, the pile tip is probable to be damaged. With the help from piling specialist, Reflect the light in the stacking toe for stacks that enable inner inspection and check for harm signs.
Blow Count is considerably smaller than anticipated:
If the blow count is much smaller than anticipated, the boring of the soil should be reviewed first. The issue may be that the stack is harmed below degree if it does not show smooth layers. Ask hand piling specialist to re-assess the splice detail and field processes for possible splice failures.
Installed batteries show side movement:
When new piles are driven, often due to land displacement. The alternatives can include redirecting the piles installed, altering the installation sequence or drilling the pile places to decrease the ground movement. The lateral pile movement in the adjoining path can also be triggered by ground failure.
