Problems solved by technology

[0002] The existing commonly used road surface snow melting and deicing methods mainly include manual or mechanical removal method, snow melting agent method, etc. The effect of snow melting and deicing is not ideal, and snow can only be melted when there is ice and snow on the road surface, and it cannot be used when ice and snow accumulate on the road. prevention before pavement
The most commonly used deicing agent can also damage the performance of the existing pavement, and has problems such as slow melting speed, low intelligence, low efficiency, and high energy consumption.

Embodiment 1

[0034] An antifreeze pavement, comprising a moisture-proof layer 2 laid sequentially from bottom to top on a pavement base 1 that has been leveled and cleaned, a heat insulating layer 3 to prevent heat from being transmitted and lost downwards, a heating cable layer 6, and a layer for fixing and protecting the heating cable layer The pavement cushion layer 7 and the pavement layer 8, a uniform heat margin protection gap is provided between the edge of the heating cable layer and the edge of the heat insulating layer, and the heating cable layer 6 includes heating cables arranged on the heat insulating layer 3 cables, a temperature-sensing probe is arranged between the heating cables, and a uniform heat gap is left between the temperature-sensing probe and the heating cable. The pavement cushion is a cement cushion.

[0035] Between the heating cables in the heating cable layer, there is a hard casing 9 with one end going deep into the heating cable layer, the other end extendi...

Embodiment 2

[0040] The difference from the above embodiment is that a heat dissipation layer 5 pressed against the heating cable layer for diffusing the heat emitted by the heating cable layer 6 is also provided between the heating cable layer 6 and the pavement cushion layer 7. The heat dissipation layer 5 is a metal mesh layer or a metal plate layer. The thickness of the pavement cushion layer 7 is 5 cm, and the distance from the edge of the heating cable layer to the edge of the pavement base layer is 12 cm.

[0041] The metal mesh is also connected with a grounding wire, and each piece of the metal mesh is connected with a bare metal wire to ensure better thermal conductivity of the metal mesh. The heating cable is fixedly connected with the heat insulating layer through a fixed connector, and the heating cable can be fixed on the heat insulating layer by punching holes on the heat insulating layer, and the heating cable layer The heating cable is divided into several sections and co...

Embodiment 3

[0043] The difference from the above embodiment is that a reflective layer 4 for reflecting the heat emitted by the heating cable layer 6 to the road surface is provided between the heat insulating layer 3 and the heating cable layer 6 . The reflective layer 4 is an aluminum foil layer. The thickness of the pavement cushion layer 7 is 3 cm, and the distance from the edge of the heating cable layer to the edge of the pavement base layer is 10 cm.

[0044]When laying the road surface, level and clean the base layer of the road surface, then lay the moisture-proof layer and heat insulation layer first, and lay the aluminum foil reflective layer on the heat insulating layer, and then lay carbon fiber heating cables evenly and firmly on the reflective layer according to the designed power and spacing. The layer is solid, and holes need to be drilled on it to fix the carbon fiber heating cable with carbon U-shaped nails or high-temperature-resistant PVC material U-shaped nails. In ...

Abstract

The invention belongs to the field of roads, and particularly relates to an anti-freezing road capable of preventing icing in cold days. The anti-freezing road comprises a moistureproof layer, a heat insulating layer, a heat-generating cable layer, a road cushion layer and a road layer which are laid on a road base layer sequentially from bottom to top, the road base layer is leveled and cleaned, the heat insulating layer prevents heat from being transmitted and lost downwards, the road cushion layer fixes and protects the heat-generating cable layer, a uniform heat allowance protecting gap is arranged between the edge of the heat-generating cable layer and the edge of the heat insulating layer, the heat-generating cable layer comprises heat-generating cables arranged on the heat insulating layer, temperature sensing probes are arranged among the heat-generating cables, and uniform heat gaps are reserved between the temperature sensing probes and the heat-generating cables. By the anti-freezing road, the problem of road icing is solved thoroughly, and a road is heated before icing of the road, so that the road is ensured not to ice while performance of the road is improved, and influence on road performance and shortening of service life of the road due to road freezing are prevented. By the designing mode, service life of the road can be prolonged, and safety of the road can be improved.
