Abstract
Introduction. At present, the connection of precast concrete pile sections using Leimet ABB+ 350 pile joints becomes very popular. The main advantages of this joint include low labor intensity (relative to the widely used welded joints) for connecting pile elements, high installation speed, as well as the absence of welding works, concreting, etc. The wide application of this joint is currently limited by the insufficient study of its parameters and, in particular, strength characteristics.
Aim. Experimental testing of the strength indices of the Leimet ABB+ 350 pile joint under the compression, tension, transverse shear, and bending.
Methods and materials. The studies were performed on the series of samples represented by two fragments of the 1.011.1-10 standard precast reinforced pile sections connected by the Leimet ABB+ 350 four-lock pin joint. Loading tests of the samples were carried out in accordance with the GOST 8829-2018.
Results. The quantitative and qualitative destruction parameters of the samples are obtained.
Conclusions. The Leimet ABB+ 350 pile joint was concluded to be of the uniform strength to the pile concrete bodies under considered impacts. The obtained results on the strength of the pile pin joint can be used in the design development and the solution of practical engineering problems.
