Применение фибробетона при восстановлении подстилающего слоя основания рельсовых путей на подкрановых балках

Abstract

A subjacent bed of concrete upon the crane girder cracks during exploitation, therefore, its crumbling leads to a break-down state of a railway-track of the crane girder. The paper deals with the problem of the creation of the subjacent bed resistant to cracking. It was determined that the fibrous concrete subjacent bed used for railway bedding upon the crane girders showed itself resistant to cracking under dynamic loads. The rational composition of fibrous concrete for the bed was chosen and the recommendations for performing works of replacing of the subjacent bed are given. The exploitation of the restored subjacent bed showed its good quality.
