ROAD TRACK BUILT UNDER COMPLICATED TERRAIN CONDITIONS

摘要

The road track can be applied, in particular for a railway line, which may be a double line. It reduces excavation works and building costs, as well as the maintenance of the railway lines. The road track has a recess, made in an inclined terrain, reinforcement facility with embankment (14) and a trench (15) for discharging waters. The reinforcement facility is a trestle consisting of columns (5), laid in strong foundations and interconnected with a longitudinal girder (13), on which a road plate (8) with a console (9) is mounted on the side of the river (11) with parapet (10). Their interconnection is by vertical anchor bolts (12), and to the inclined terrain - by horizontal anchor bolts (13). Between the road plate and the trench and over the intact soil base an asphalt-concrete surfacing (16) is made on which a horizontal diaphragm (17) is stuck. On it a ballast prism (18) with rail-and-sleeper grating (19) is fitted. Along the whole section in the embankment (14) a diaphragm (22) is mounted with an arc-shaped projecting section along the direction of the recess. 12 claims, 11 figures
