The response piles are installed through the test pile at a minimum amount distance, And so the reaction piles tend not to impact the loading of the test pile. On an average compression take a look at, the response beam is cribbed a distance off of the bottom to support the test jack and load cell amongst the exam pile and The underside from the examination beam. The compressive load is then applied to the pile with the examination jack reacting Small diameter piles versus The underside from the beam. The prestress power about the response piles retain the beam from rolling.
