Ice and snow melting device for PC rail beam, paving method and PC rail beam

The invention discloses an ice and snow melting device for a PC rail beam. The ice and snow melting device comprises a heat-conduction cover plate, a bottom plate which is connected with the heat-conduction cover plate in a dismountable manner, a heat tracing band component which is arranged between the heat-conduction cover plate and the bottom plate and used for supplying heat to the heat-conduction cover plate, and a connection component for connecting the heat-conduction cover plate and the bottom plate with beam concrete on the ground. Through the adoption of the ice and snow melting device disclosed by the invention, ice and snow on the PC rail beam can be rapidly and effectively melted, the trains can be further guaranteed to normally run, and the stop or delay of the trains can be avoided; besides, the ice and snow melting device is convenient to mount and dismount, and is convenient and flexible to maintain and replace. In addition, the invention further provides a paving method and the PC rail beam based on the ice and snow melting device for the PC rail beam.
