MULTIPLE-LANE RAILWAY CROSSING Russian patent published in 2000 - IPC

FIELD: transportation engineering. SUBSTANCE: multiple-lane railway crossing has roadway lying at level of wheels. Roadway is formed by self-bearing slabs. Provided are internal slabs which cover space between rails of each lane and they rest on these rails, and external slabs with their side resting against external side of rail of each lane. At other side, they are in thrust by supporting beam located next to rail. In intermediate space between two adjacent lanes, roadway is formed by self-bearing equalizing slabs. Both longitudinal edges of equalizing slabs are in thrust by supporting beams, which also support external slabs of corresponding roadway lanes. It is feasible to manufacture equalizing slabs from polymer-impregnated concrete and also from polyester concrete. Aforesaid embodiment of multiple-lane railway crossing allows for ensuring similar properties of roadway. It particularly relates to ensuring similar cohesion of roadway surface through entire section of crossing. Due to that, even after long period of service, level of upper surfaces of slabs is not changed. EFFECT: higher efficiency. 7 cl, 3 dwg
