The response piles are mounted from your take a look at pile in a bare minimum length, Micropile design specifications so the reaction piles never influence the loading from the take a look at pile. On a standard compression exam, the reaction beam is cribbed a distance off of the ground to accommodate the take a look at jack and load mobile between the check pile and The underside of the examination beam. The compressive load is then placed on the pile in the test jack reacting towards the bottom on the beam. The prestress drive within the reaction piles hold the beam from rolling.
