We drove fifty four″ OD and sixty six″ OD concrete cylinder piles for eighteen miles. With this distinct Picture, we have been jetting the piles right down to a predetermined depth then they have been concluded with big hydraulic and air hammers. Picture credit rating: APE Troubleshooting and customary Challenges

The casing may perhaps increase to the whole depth or may possibly terminate higher than the bond zone, Together with the reinforcing bar continuing to the full depth.

A few other probable will cause of this situation consist of a spliced pile, an obstruction, or uneven Get hold of with the toe. Inspect the toe region for any harm which will have transpired.

Blow counts are calculated in advance. When the blow depend is different in the field, there’s likely a problem. Listed below are typical issues and solutions linked to blow count:

Which has a shorter stroke, these hammers raise the blow charge once the ram is accelerated throughout the downstroke, and pile-driving pace increases.

There are many problems that can come up in the field. Planning and contingency organizing will be the essential to preserving a pile driving job on the right track and on spending budget.

Steel casing that has a tapered surface area, micropiles is usually grouted through Slice-outs while in the wall. The micropile functions like a design device that can assist the burden of the composition or undertaking on its own during curing.

The inherent challenge of pile driving is always that it specials with soil Which There are tons of possible problems with this set up. However, if you intend and look at many of the possible problems that come with pile driving, it is possible to be improved ready to mitigate them.

Issues can happen even in/under the best of situation. [=regardless of whether your situation is nearly as good as you possibly can]

Inspect the inside of the pile for harm to the pile toe. If You're not in a position to do an inside inspection you must Assess the issue this site making use of dynamic measurements. Or, you will have to extract the pile.

In which easy pile driving will cause partial horizontal cracks inside a concrete pile, Check out the hammer-pile alignment. An additional doable trigger is often a combined stress and bending that may be as well significant.

Template programs make certain precision in pile placement, which is important for structural integrity. They assist sustain the proper alignment and depth of piles, especially in hard environments, decreasing the chance of misalignment and structural failures.

You should also evaluate tensile stresses together the pile and compressive stresses for the toe. Other leads to could be a spliced pile, an obstruction, or perhaps the toe Make contact with is uneven. Check for toe destruction.
