Pile testing with vertical static load using injection anchor piles.
This pile test method implemented using radially spaced, drilled injection anchor piles under an angle. Injection anchor pile number and length determined by calculation, taking into account the test load and geological conditions. Injection anchor piles are joined by a special metal construction, carrying out support functions of the hydraulic jack.
Pile testing is done gradually increasing load on the hydraulic jack assistance according to the pile-testing program, as certified by the designer. For pile testing use a calibrated hydraulic jack, which is installed in the test pile at the top (between the piles and metal construction). Pile top is reinforced with metal shells. Around the test piles is installed a special metal frame, on which is mounted special calibrated measuring tools (tensiometer), by which measure pile settlement. Reaching the maximum test load, carry out gradual pile unload. This is followed by a report with a graph depicting which shows a pile test results.
This test method acceptable to test piles with load till 1000 t.
IMPORTANT: During the test cannot carry out construction works, which creates dynamic load and vibration near testing pile area. This may adversely affect measuring instrument readings (tensiometer), which can lead to inaccurate pile test results.
