Pile lateral load test is usually conducted to estimate the lateral capacity of a pile. Piles are generally used to transmit vertical loads to the surrounding soil. However, they are also sometimes subject to lateral loads due to wind pressure, water pressure, earth pressure, earthquakes, etc. When the horizontal component of the load is small in comparison to the vertical load, it is generally assumed to be carried by vertical piles and no special provision for lateral load is made. Piles that are used under tall chimneys, towers, high rise buildings, high retaining walls, bridges and other concrete elevated structures are normally subjected to high lateral loads. These piles should resist not only to vertical loads but also to lateral loads. The interpretation of the test measures:
This non-destructive test method is a quick method to evaluate the shaft integrity of concrete piles. The test results provide information on
The test method is performed with a handheld hammer, a sensitive accelerometer, and the Pile Integrity Tester.
The accelerometer is attached to the top of the pile, and then a compressive wave is generated by tapping the pile head with a hammer. When the downward compression wave encounters a change in cross section or in concrete quality, it generates an upward tension wave that is later observed at the pile top.
The velocity recorded along with the subsequent reflections from the pile toe or pile discontinuities are graphically displayed.
The effectiveness of the system is limited to a pile length not exceeding 30 to 60 pile diameters depending on soil condition and concrete quality.
Gulf Foundation has the equipment and experience to monitor vibration intensity in and around a project site. This usually concerns vibration caused by vibratory or impact hammers during piling works, heavy machinery, or rock blasting works.
