C-pile testing

Hello civil engineers,

What was it again?

The C-piles we talked about earlier last month have been tested! And it went alright. The C-pile is a micropile where there is a strip of steel “cut out” in the side of this making it the form of a C. On the other side of this cut out strip there is T part welded to the micropile making it able to connect to each other.

The test was to make a C-pile wall with 6m and 8m piles. The piles went in nicely and there were no problems found here.

Drilling them in

Drilling the piles into the ground was no problem. The soil consisted of moraine, this means there were some big rocks in the layers under the surface. When one of the rocks was encountered the drilling continued without any problems. The piles were connected one by one by shoving the T part in to the to the empty space where the strip of steel was removed. The piles weren’t bent or showed any sign of damage after the drilling. For the future there will be more optimisations to ensure speed and working effect.

The test.

The test of the piles went very well! The wall was tested with an excavation of 3 by 4 meters. The testing was done by filling the CT piles with sand an poles where set in to the pile so there was a starting point for the measurement. Measuring was done by surveying the distance by hand. As you will see on the photos. A very good result was obtained and further testing can be done. The testing was done during 4 hours so this is a very short period of time. A next test would be that this time period would be 4 days to see how the piles would take the pressure. Also the lock system of the piles worked very well, and never broke during the tes
