White synchronization railway

Abstract

The invention relates to a technology for white synchronous railroad, which uses a glabrous white heat isolation layer to be coated on a railroad. A sleeper, in particular a steel sleeper, is coated with the glabrous white heat isolation layer, thereby substantially shortening the range of temperature change of the railroad, realizing the synchronous thermal expansion between the railroad and a roadbed, just like the synchronous thermal expansion between steel reinforcement and concrete in reinforced concrete, and completely solving the problem of the thermal expansion of the railroad.

Description

Technical field

[0001] The invention paints a smooth white heat insulation layer for the railway, greatly reduces the temperature range of the railway, realizes the simultaneous thermal expansion of the railway and the track bed, just like the synchronous thermal expansion of the steel bars and concrete in reinforced concrete, and completely solves the problem of thermal expansion of the railway. Background technique

[0002] The biggest problem in railway engineering is the thermal expansion of the railway. At present, there are two types of known railway thermal expansion control technologies, one is slotted railway, and the other is seamless railway;

[0003] The seamed railway uses expansion joints between adjacent rails to absorb the thermal expansion of the railway. Its advantages are: simple structure, easy construction, and low cost; the disadvantages are: the range of expansion joints is too large, and the impact of wheels and rails is serious. And thus produce a s...

Embodiment

[0031] A white synchronous railway, every two adjacent rails (3) and (4) are connected together and laid on channel steel sleepers (7), the feature is: the rails (3) and (4) are painted smooth White heat insulation layer (6); the sunshade edge (e) is used to block the sun and cold wind, suitable for railways without scattered objects, for example, suitable for closed train lines; the design of this train will take into account the sunshade edge; safety The section (M) and the safety edge (N) are painted with clean white; the two ends of the channel steel sleeper (7) are closed and painted with a clean white heat insulation layer; the contact surface (A) between the rail and the steel sleeper is derusted Fit to facilitate heat conduction between rail and sleeper.

[0032] When the whiteness of the railway surface is high and the finish is also high, both of them have a high anti-radiant heat effect. Although one of them is far from enough to reflect all the radiant heat, the su...
