Piles are repeatedly veteran next to immense cost and effort, as consequences are significant in verifying foundation plan parameters and formulating counteractive measures when desired. Because such, the data has to subsist recorded with a towering amount of accuracy and integrity. 

Benefits of Pile Testing

Increased class assurance
Cost effective
Can experiment a greater number of piles
Operate to standards
Tests are approved absent quickly

A pile integrity test (also acknowledged as lowstrain dynamic test, sonic echo experiment, and low strain integrity test) is one of the methods for assessing the condition of piles or shafts. It is cost efficient and not extremely point in time consuming.

During the construction of profound foundations there are dissimilar state of affairs that are expected to affect the concluding figure of piles that tend to involve the planned deepness, irritated segment and material superiority. For quality be in charge of pledge of these elements pile integrity investigation (PIT) is repeatedly used.

Pile Integrity Test (PIT) as a method that involves the impact of a hammer lying on the head of the pile generating a low strain compression wave that propagates down the pile and afterwards is reflected next to the bottom of the pile, before where present are changes of impedance connected with variations in irritated segment otherwise density of the material.

Importance of Pile integrity tester the stage an competent position throughout before after construction.

The Pile Integrity Tester is available in 4 models, with one (PIT-X and PIT-V) or two (PIT-X2 and PIT-FV) channels of data acquisition:

PIT-X and PIT-X2 are tiny and light, and understand maringo statistics from wireless accelerometers.

PIT-X2, old in 2 velocity mode, enables the tester to investigate information from 2 accelerometers; this may live functional designed for seminal indefinite foundation length.

PIT-FV reads data from one (traditional) accelerometer and one instrumented hammer before from two accelerometers. It permits force and velocity analysis in the Frequency Domain for a added thorough evaluation of the integrity of the foundation and allows the investigation of defects by the pile pinnacle. PIT-FV may also live worn to assess of the depth of an unidentified foundation.

Construction setting up adopts a completeness with a wll designed strategies and techniques, allowing for the equipment effect in addition. An another taxing thing is concerned in the construction neighborhood i.e Crosshole sonic Logging.

Crosshole Sonic Logging (CSL) is the most correct and steadfast practice designed for assessing the integrity of profound foundation rudiments constructed on-site as of tangible or else grout. The crosshole sonic lo gging method is usually functional as a quality declaration (QA) technique intended for newly positioned drilled shafts and auger cast piles, excluding can as well be alive useful to slurry walls, rug foundations, and mass tangible pours.

Secant heap ramparts are fashioned by a series of interlocking drilled shafts. Primary piles lacking reinforcement are built initial. The gaps are filled  by less important unbreakable piles, which overlap the primary ones . The tangible of the primary mountain is often selected to subsist weaker than for usual piles to facilitate drilling.

Standard heap drilling rigs are used meant for construction Crosshole Sonic Logging (CSL) was until currently partial to live functional surrounded by the reinforcement cage of a single heap. Thus there is no likelihood to confirm the integrity of the primary piles previous to dig. Even if elevated standards are practical, the construction from time to time fails, e.g. next to unexpected soil in homogeneities.
