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

[0042] A road body structure, including a moisture-proof layer 2 laid on the leveled and cleaned road base 1 sequentially from bottom to top, a thermal insulation layer 3 to prevent heat from being conducted and lost downwards, a heating cable layer 6, and a heating cable layer that is fixed and protected The pavement cushion layer 7 and the pavement layer 8, the heating cable layer includes a plurality of uniformly distributed heating areas, and a number of heating cables 62 arranged in parallel are connected in parallel on the heating areas, and a uniform heat increase is formed between adjacent heating cables. Friction gap 64, a reinforced fixed gap 61 is left between adjacent heating areas, and a temperature sensing probe is arranged between at least one pair of adjacent heating cables in each heating area, and a uniform heat is left between the temperature sensing probe and the heating cable. Gap 63, a heat dissipation layer 5 for evenly diffusing the heat emitted by the h...

Embodiment 2

[0048] The difference from the above embodiment is that the heat insulation layer and the reflective layer are glued and fixed, and there is a layer between the heating cable layer and the pavement cushion layer to prevent the heating cable in the heating cable layer from arching or The twisted mesh presses against the layer 51 . The reflective layer 4 is an aluminum foil layer, and the heat dissipation layer 5 is a metal mesh layer or a metal plate layer. The application selects a metal mesh layer, and the reflective layer or reflective layer and heat insulation layer or reflective layer, heat Reinforcement fixing holes 71 are provided for infiltrating into the pavement cushion material to form the reinforcement fixing columns of the anti-staggering 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.

[0049] The metal mesh layer is also connected with a groun...

Embodiment 3

[0051] The difference from the above embodiment is that 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 road body structure. The structure 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 multiple parallel heating cables are connected in parallel on the heating areas. Heat uniforming and friction increasing gaps are formed between adjacent heating cables. Reinforcing and fixing gaps are reserved between adjacent heating areas. A temperature sensing probe is arranged between at least one pair of adjacent heating cables of each heating area. Heat uniforming gaps are reserved between the temperature sensing probes and the heating cables. 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 body 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 a road body structure capable of preventing road surfaces 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 a road body structure with a high degree of intelligence, which can completely solve the prob...
