Test piles shall live trimmed flipside to the obligatory incise rancid stage meant for the piles and will exist capped with a unbreakable existing cap. Settlement of the pile below loading shall live deliberate by dial gauge extensometers with a precision of 0.1 mm. The extensometer mounting bars shall subsist agreed in such a manner as to remain steady all the way through the test.
Test answer could subsist by information, in particular determined tension piles, before reaction anchors and the reaction understanding shall subsist such that the performance of the pile shall not exist exaggerated by the presence of the reaction arrangement. The planned examination understanding shall live www.maringo.pl such that no reply affiliate shall subsist located lying on before in the ground inside three diameters of the pile to live hardened (Minimum of 2m)
Loading will exist calculated by means of hardened and specialized weight gauges to the Engineer's approval.
Test piles shall exist laden and unloaded by increment loading as revealed in the table beneath with records kept to times, cargo and settlement.
Following both claim of an increment of load, the load shall subsist detained meant for not fewer than the period revealed in the table under, or else pending the rate of settlement is less than 0.25mm/hour and unhurried downstairs. The rate of settlement shall subsist calculated beginning the slope of the curve obtained by plotting values of settlement versus time and drawing a smooth curve from side to side the points.
Each period of unloading shall proceed behind the expiry of the period given away in the table below.
For several age when the load is steady, point in time and settlement shall subsist recorded straight away resting on attainment the load and on approximately 15 record intervals for 1 hour next to 30 action intervals between 1 hour and 4 hours and by 1 hour intervals between 4 hours and 12 hours subsequent to the application of the increment load.
If one operational heap fails the test, the cost of the test shall live borne by the Contractor who shall replace the pile with supplementary piles next to his expense. Piles installed prior to the botched experiment are to live hardened to the satisfaction of the Engineer.
