HANDBOOK FOR THE CORRECTION OF RAILWAY TRACK ON HEAVING GROUND
INSTRUKTSIIA PO ISPRAVLENIIU ZHELEZNODOROZHNOGO PUTI NA PUCHINAKH
A heaving is considered to be a local intense rise of a deformation of the position of the track in transverse and longitudinal profile, arising as the result of the heaving of frozen soils of the roadbed and the ballast layer. Heaving develops as the result of increases in the volume of the frozen soil of the roadbed or the ballast layer as the result of freezing of water in it and the formation of icy impurities in the form of a lens, interlayer, or streak. The icy impurities are formed from water contained in the soil or in the ballast layer below the freezing and advancing into the freezing layer from the contiguous zones of the uniform soil. The chapters cover such topics as the technical requirements for the correction of the track on heaving, heaving blocks and spikes, regulations for the application of heaving blocks and spikes, fundamental rules for the correction of the track on heavings, means for the correction of the track, composition of the measuring work (with ranging rods), work procedures during heaving; work procedures during settlement of the heavings by means of gradual lowering, and finally, work procedures during settling of the heaving by means of incrementation.
