Investigation of boring pile integrity of road systems in engineering-geological condition of Kazakhstan

Abstract

The paper considers the testing of pile foundations for continuity at the Atbasar pipeline facility. For testing monolithic concrete and reinforced concrete structures, a variety of the pit (pile integrity test) method is used – low-deformation dynamic tests. This is the most modern technique in the world practice of recent years. It allows you to check the continuity of all types of monolithic concrete and reinforced concrete structures, including concrete (reinforced concrete) piles, to identify defects in them. Based on the obtained pile data, as a result of testing for the continuity of foundations, the number of non-defective piles and defective piles are reflected and solutions are proposed to ensure the reliability and safety of the pipeline operation. A total of 10 bored piles, which were located in 4 separately standing foundations, were investigated in the work. The results showed that 3 piles could have defects in the form of cracks or narrowing of the cross-section of the bored piles.
