I am currently exploring the possibility of using vibro hammer for the installation end-bearing steel H-piles due to environmental concern. Does anyone has any experience using vibro hammer for the installation of end-bearing piles? If yes, what are the pile performance (capacity and load-settlement)? What are the measures taken to ensure proper seating? Many thanks in advance.
I might add to Rainer's comments that if the pile is installed using vibratory methods because of environmental concerns, it may be acceptable to give the pile a small number of impacts with a pile driving hammer in its installed position. Much of the energy will be transmitted to the soil at depth, and the surface effects may be significantly reduced and acceptable. Stress-wave measurements would then be performed to ensure compliance with acceptance criteria. Of course, static load testing is another (expensive but vibration-free option).
