A pile test (also referred to as low strain dynamic test, sonic echo test, and low strain integrity test) is one of the means for measuring the form of piles or tubes. It is cost effective and not very time consuming.
During the building of deep foundations, there are diverse conditions that are probable to affect the final form of piles, incline to touch the planned depth, cross section and material value. For quality control assurance of these basics pile test is frequently used.
It is a technique that contains the influence of a hammer on the head of the pile, producing low strain density waves that spreads along the pile and later is reproduced at the bottom of the pile, or where there are changes connected with deviations in the cross section or density of the material.
Prominence of Piling pipe integrity tester plays an effectual role during or after construction. Construction planning construes of well-planned policies and methods, and its effect also. Another testing factor is included in the construction zone i.e. Crosshole sonic Logging.
Crosshole Sonic Logging (CSL) is the most precise and dependable method for measuring the integrity of deep foundation features built on-site from concrete or grout. This method is generally used as a quality assurance (QA) method for newly located bored tubes and auger cast piles, but can also be used in slurry walls, mat foundations, and solid mass pours.
Secant pile walls are molded by a sequence of intertwining bored tubes. Primary piles without support are made first. The openings are occupied by secondary reinforced piles, which overlay the primary ones. The concrete of the primary pile is often preferred to be weaker than for ordinary piles to enable boring.
Standard pile boring rigs used for building Crosshole Sonic Logging (CSL), was till now restricted to be functional within the reinforcement cage of a single pile. So, there is no option to check the reliability of the primary piles before mining.
