Loads acting on the equipment’s destructive elements for removing the reinforced concrete piles’ ends

Abstract

Cutting off the reinforced concrete piles’ column heads is an important technological operation in the pile foundation construction. High-quality reinforced concrete piles column heads cutting should be performed at a given mark, without cracking concrete below the cut level. At the same time, reinforcing rods of the pile together with concrete are not removed. The rational equipment design for cutting the reinforced concrete piles’ column heads is complicated by the lack of information on the required forces developing on the working body of the machine. The theoretical justification of these forces is not possible, due to the lack of appropriate guidelines. To this end, the article presents the experimental studies’ results to determine the loads on cutting elements when cutting a reinforced concrete pile of square cross section. The experimental work technique is described, the conclusions of the study are presented.
