Abstract

The invention relates to the field of transport construction, in particular to the construction of the carriageway of tram crossings. The aim of the invention is to increase the operational reliability of the coating. The covering of the tram crossing includes reinforced concrete slabs 5 laid on the base between the tracks, the inter-rail space and on the roadsides, each of which is made with openings 6 under the corresponding route 7 of the tram track 8. The plates 5 laid on the sides of the tramway are aligned parallel to the axis of the tramway by bevel 9 in the upper part and a vertical protrusion 10 located on its end portion. The plates 5 can be made with a protrusion on one of the ends and a ledge on the other, while the adjacent plates and 5 are connected between fight over the length of the tram moving with the help of fasteners. 1 hp f-ly, 5 ill. 3 (L

Description

f

The invention relates to transport construction, and in particular to the construction of the carriageway of tram crossings,

The purpose of the invention is to increase the operational reliability of the coating.

Figure 1 shows the floor of the tram crossing, plan; FIG. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB in FIG. 1; FIG. 4 is a section B-B in FIG. 1; in FIG. 5, node I in FIG. 4,

The covering of the tramway crossing includes reinforced concrete slabs 5 laid on base 1 in interpath 2, inter-rail space 3 and on the roadsides 4, Each slab 5 is made with openings 6 for the corresponding sleeper 7 of the tram way 8, Plates 5 laid on the roadsides 4, made with a bevel 9 aligned in parallel with the tramway axis in the upper part and with a vertical projection 10 located on its end portion.

The plates 5 can be made with a protrusion 11 on one of the ends and a ledge I2 on the other, and the adjacent plates 5 are interconnected along the length of the lap overlap by means of fasteners 13,

The width of the openings 6 must be 10–15 mm greater than the width of the sleepers 7, and the height of the openings 6 is greater than the height of the sleepers by 30–40 mm to ensure freedom of deformation of the plates 5.

The peculiarity of the configuration of the plates 5, laid on the shoulders 4, is due to the fact that the end portion of the plate is under the pavement 14 and performs the function of the transition element from

pavement 14 with less rigidity to the design of the plate 5 with greater rigidity.

The protrusion 10 prevents the pavement layer 14 from sliding to deform the latter.

To prevent contamination of the base 1, under the plates 5, a rubber bar 15 is placed between the rails of the tramway 8,

In the proposed construction, an isolated operation of the road surface and the track is ensured, which increases the operational reliability of the crossing.

Claims (2)

Invention Formula 1, Tram level covering, including reinforced concrete slabs laid on the ground between the track, the inter-rail space and on the roadsides, due to the fact that, in order to improve operational reliability, each slab is complete with openings in the lower part under the corresponding sleepers of the tramway, and the plates laid on the sides, are made with a bevel in the upper part parallel to the axis of the tramway and located on the end portion of the vertical projection, 2. Covering pop, 1, differs with the fact that the slabs are made with a protrusion on one end and a ledge on the other, with the adjacent plates interconnected along the length of the lap overlap with the help of fasteners, ABOUT 0-d Editor A.Dolinich Compiled by V.Gonik Tehred A.
