Method for testing integrity of concrete shafts

摘要: A method for detecting and locating foreign inclusions in a drilled cylindrical shaft includes the steps of positioning at least one logging tube within parallel relation to longitudinal axis shaft, providing temperature sensing means, identifying plurality locations along extent tube, pouring concrete into covering monitoring real time various depths radial directions during hydration phase curing. Temperature readings that differ from expected are deemed positioned vicinity an anomalous inclusion. The range over which these detected, magnitude variance, orientation used predict size location anomalies prior full curing concrete.
