The reaction piles are set up from your examination pile at a minimum length, so the response piles usually do not impact the loading in the test pile. On a normal compression exam, the response beam is cribbed a length off บริษัทรับตอกเสาเข็ม of the bottom to support the take a look at jack and load mobile in between the check pile and the bottom of the test beam. The compressive load is then applied to the pile through the check jack reacting versus The underside of your beam. The prestress drive to the response piles preserve the beam from rolling.
