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

[0051] A road body construction method with cold protection function, comprising the following steps:

[0052] 1. Conduct a power-on test before the heating cables to be laid enter the site to check whether each heating cable can work normally, and level and clean the pavement base 1;

[0053] 2. Laying the moisture-proof layer 2, the moisture-proof layer can choose PVC moisture-proof film;

[0054] 3. Lay the heat insulating layer 3 and the reflective layer 4, the reflective layer is an aluminum foil layer glued on the heat insulating layer;

[0055] 4. Laying the heat dissipation layer 5. In this application, metal mesh is used as the heat dissipation layer. Adjacent metal mesh layers are crimped or connected by conductors. The conductors can be copper wires, and the metal mesh is grounded. The metal mesh includes primary heat dissipation strip sections 51 with dense mesh wires and secondary heat dissipation strip sections 52 with sparse mesh wires arranged at intervals in se...

Embodiment 2

[0064] The difference from the above embodiment is that the thickness of the pavement cushion layer 7 is 5 cm, and the distance from the outer side of the heating cable layer close to the side of the pavement base layer to the side of the pavement base layer is 12 cm.

Embodiment 3

[0066] The difference from the above embodiment is that the thickness of the pavement cushion layer 7 is 3 cm, and the distance from the outer side of the heating cable layer close to the side of the pavement base layer to the side of the pavement base layer is 10 cm.

[0067] This application completely solves the problem of icing on the road surface, and heats the road surface before the road surface is icy, so as to ensure that the road surface will not freeze and at the same time improve the performance of the road body, prevent the road surface from freezing to affect the performance of the road body, and shorten the service life of the road body. At the same time, carbon fiber cables are used, which have high safety, and the heating temperature will not be too high. Excessive temperature will also affect the performance of the road body. Through the design of the road body in this application, the service life of the road body can be extended and the road surface can be im...

Abstract

The invention belongs to the field of road construction, and particularly relates to a road body construction method with a cold preventing function. The road body construction method comprises the following steps: 1, conducting a power-on test on heating cables to be paved before approach; 2, paving a damp-proof layer; 3, paving a heat insulating layer and a reflecting layer; 4, paving a heat dissipation layer; 5, paving a heating cable layer; 6, punching the reflecting layer, the heat insulating layer and the damp-proof layer: punching the reflecting layer, the heat insulating layer and the damp-proof layer from top to bottom corresponding to the clearances of the well distributed heating cables to form clearance cylindrical holes; 7, arranging temperature sensing probes: arranging hard sleeves among the paved heating cables, fixing the hard sleeves, arranging the temperature sensing probes in the hard sleeves, and electrically connecting the temperature sensing probes with a temperature controller outside the road body, and then blocking the ends, away from the edge of the road body, of the hard sleeves; 8, paving a road surface cushion layer; 9, paving a road surface layer. Through the adoption of the road body construction method, not only can road surface icing be avoided, but also the performance of the road body can be improved.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a road body construction method with the function of keeping out cold. 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 purpose of this invention is to provide a kind of road body construction method that has the function of keeping out the cold in view of the abov...
