INTEGRATED DESIGN OF LONGITUDINAL AND TRANSVERSE PROFILE HUMPS

Abstract

Quality and safety disbandment process formulations humps depend on many factors. When integrated design of the longitudinal and transverse profile hump yards must be considered quite controversial issues requiring in each case decisions using sound technical and operational and economic calculations. Cross-section of sub grade marshalling parks designed, usually a saw tooth. In the distance between the tracks the lowest marks arranged longitudinal drainage trays. Slopes cross members sub grade depend on soil type and clay soils are 0.02. Height difference roadbed along the axis of the beam extreme ways of eight tracks is thus 0.74 m. Applying the same within one beam gable profile sub grade to reduce said difference will lead to the need to accommodate the longitudinal drainage trays between the beams, which will significantly increase the cost of construction. The maximum difference in height of the rail heads extreme one beam paths can be achieved at the maximum slopes of elements on one of them and minimum differently. This difference is of the order of 0.14 m. The slope of the transverse elements Compliance sub grade elevations and rail heads marshalling lines within a single beam leads to the necessity of increasing the thickness of the ballast layer with increasing difference between the mark and the mark of the railhead sub grade. Transferring the park brake position is closer to the last separating arrows necessitates their placement in the general pit. At this level of the rail head cross-sectional areas of paths in retarders must be identical. To implement such a solution must be on the top of the sub grade layer stack draining soil with characteristics that allow you to have a horizontal surface. This allows you to minimize the cost of drainage facilities and to design ways of sorting the latest dividing arrows with the same marks on the rail head.
