Apparatus for testing, in situ, the static load capacity of a pile comprises a jack (20) supported by the pile (21) and a reaction beam (13) supported by blocks or trestles (24), the jack is raised to come into contact with the reaction beam (13) via a spherical seating (22) and a spreader plate (23). The reaction force from the jack is counteracted by an anchor arrangement at each end of the reaction beam (13) via secondary beams (15) themselves anchored down to anchor piles (25) via threaded steel tendons or bars (14). The reaction beam (13) is made up a number of constituent parts (10, 11, 12) which bolt together to make one reaction beam (13), the weight and size of each constituent part enable this apparatus to be erected in restricted access without the need for craneage. |
