Driving process complications might be connected to small hammer efficiency or cushion which is too comfortable. The soil might have increased energy, increased damping ration, or larger sized soil quakes than Original testing anticipated.

Where by the blow count is much decreased than anticipated, critique the soil borings. If there's no indicator of soft layers, the pile could possibly be damaged beneath the grade.
The instruments which can be to be used to the pile Basis should be explicitly integrated into the programs.
In cases like this, ram friction could be the induce. If the noticed blow count is under calculated, soil resistance is probably going reduce than at first approximated. If they are similar, use decrease combustion tension to align the hammer stroke.

In diesel pile drivers, a piston compresses the air and fuel inside a cylinder on an effect block, developing an explosion. The ensuing power pushes the pile beneath down into the bottom and moves the piston again up within the housing to reset before coming down once again.
You will have to do restrike screening in the case of lower soil resistance. This requires creating the set up aspect and driving to some lessen capacity. Assess hammer functionality and make changes, if required.
The wave equation — or stress-wave theory — tackled a lot of of these concerns. Australian David Victor Isaacs drive piles for foundation researched using the dynamic formula with concrete piles, and produced a mathematical design that took into consideration the successive transmission and reflection of waves.
When employing a wave Examination software program program to forecast pile behavior, chances are you'll operate into knowledge challenges. If the particular hammer that pile driver job description you are employing isn't stated when you find yourself moving into wave Evaluation facts, utilize a hammer of precisely the same style. It should have the same Electrical power ranking and ram weight.
