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

[0040]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 7 and the pavement layer 8, the heating cable layer includes a plurality of evenly distributed heating areas formed by at least one heating cable 62 arranged on the heat insulating layer 3, and reinforcements are left between adjacent heating areas. A fixed gap 61, a temperature-sensing probe is arranged between the heating cables in each heating area, and a uniform heat gap 63 is left between the temperature-sensing probe and the heating cable, and a gap 63 is provided between the heating cable layer and the heat-insulating layer. The heat dissipation layer 5 in which the heat emitted by the heating cable layer spreads evenly. Eac...

Embodiment 2

[0046] The difference from the above embodiments is that 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. 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 connected in parallel.

Embodiment 3

[0048] 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 heat dissipation layer. 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.

Abstract

The invention belongs to the field of roads, and particularly relates to a novel anti-freezing pavement. The pavement comprises a damp-proof layer, a heat insulation layer, a heating cable layer, a pavement cushion layer and a pavement layer. The damp-proof layer, the heat insulation layer, the heating cable layer, the pavement cushion layer and the pavement layer are sequentially laid on a leveled and cleaned pavement foundation layer from bottom to top. The heat insulation layer prevents heat from conducting and being lost downwards, and the pavement cushion layer and the pavement layer are used for fixing and protecting the heating cable layer. The heating cable layer comprises multiple evenly distributed heating areas, and each heating area is formed in the mode that at least one heating cable is distributed on the heat insulation layer. Reinforcing and fixing gaps are reserved between adjacent heating areas. A temperature sensing probe is arranged between the heating cables of each heating area. Heat uniforming gaps are reserved between the temperature sensing probes and the heating cables. A cooling layer used for evenly dispersing heat generated by the heating cable layer is further disposed between the heating cable layer and the heat insulation layer. The structure completely solves the pavement freezing problem, a pavement is heated before the pavement is frozen, and it is guaranteed that the pavement can not be frozen; meanwhile, the performance of a road body is improved, and the situation that road performance is affected and the service life of the road body is shortened due to pavement freezing is prevented.

Description

technical field [0001] The invention belongs to the field of roads, and in particular relates to an antifreeze road surface which can prevent the road surface from freezing in cold weather. Background technique [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. Take precautions before pavement. The most commonly used deicing agent can also damage the performance of the existing pavement, and has problems such as slow snow melting speed, low intelligence, low efficiency, and high energy consumption. Contents of the invention [0003] The object of the present invention is to provide an antifreeze road surface with high intelligence degree, which can completely solve the ...
