Title of the articleThe vertical planning of the street and road network (SRN) – the main component of drainage
Abstract.The vertical layout of the road network is the backbone of improvement in the cities and towns. Create a relief project contributes to: 1) improve the conditions of the traffic, as the accepted optimal longitudinal and transverse slopes on the roadway; 2) improvement of pedestrian traffic, the adoption of a more gentle slope within 10-15 ‰; 3) planning and dividing strips of lawn with taking into account the terrain; 4) the preservation of optimum conditions for the foundations of adjacent buildings , the slope of the blind area must be not less than 150 ‰; 5) maintenance of surface drainage through the formation of longitudinal and transverse slope to the trays carriageways and on to a rain water intake wells. The latter figure is determined by two main items: 1) the provision of drainage should be determined taking into account the possible flow of storm and meltwater, which is based on the regional characteristics of the countryside from the standpoint of climate and nature of the proposed surface topography, and 2) the transverse and longitudinal slope and width of the individual elements of the planning structure. A particularly large number of defects observed on the straight and wide areas of roadways in trade and public and administrative buildings. In these areas should create additional watersheds «combs» which form the cross- flow on the flat and wide sections of roadways. Avoid zero longitudinal slope, as this makes it difficult to runoff culvert devices. When drafted, in this case, you need the tray along the roadway to arrange «sawtooth» longitudinal profile.
Keywords.Road network, project relief, aquaplaning, drainage, priest river gradients, paving, line construction.
