Description

Technical Field

[0001] The invention relates to a road structure and a snow removal method, and more particularly to a heating floor structure and a road snow removal method. Background Art

[0002] Accumulated ice and snow make the road slippery, resulting in a significant reduction in the friction coefficient of the road surface, especially in some special sections, such as bridges, curves, steep slopes and other sections, where traffic accidents are prone to occur. Existing solutions for road snow removal are not perfect, and the snow removal efficiency is poor. For example: Chinese Patent Announcement No. CN114319011A, Announcement Date April 12, 2022, the invention name is a complete set of snow and ice melting equipment for highway pavement and its deicing method. The application discloses a snow removal device, which is achieved by laying an outer protective casing underground on the highway, and laying a heating cable inside the outer protective casing. The heating cable can be protected by the outer protective casing. After the heating cable is heated, the heat is transferred to the copper outer protective casing, and the highway pavement is heated through the outer protective casing, so that the highway pavement temperature rises above the freezing point, thereby melting snow and ice on the highway pavement; this scheme is not only complex in structure, but also obviously insufficient in snow removal efficiency.

[0003] Some foreign countries have also explored road snow melting technology. For example, Canada's Warmly Yours company adopted the concept of floor heating and laid wires underground to melt snow. When snow falls on the ground, the sensors in the heating system will detect the temperature and humidity. When the temperature is too low, that is, when the road is frozen, the heating switch is automatically turned on to perform snow removal operations. To this end, our company has established a research project on "A PAE heating floor system and its application in snow melting and ice removal on special sections of highways". The research and development of optimized new materials and road heating systems are combined and applied to snow removal technology to design a solution with simple structure and high snow removal efficiency. Summary of the invention

[0004] The present invention overcomes the problem of low snow melting efficiency on existing highways and provides a heating floor structure and a road snow removal method. The heating floor structure of this scheme is simpler and has higher snow removal efficiency, which greatly improves the traffic safety of special dangerous sections in rainy and snowy weather.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a heating floor structure, including a base layer, a snowmelt layer is laid on the base layer, the snowmelt layer includes a heating layer, a road surface layer and a thermal insulation layer are respectively provided on the upper and lower sides of the heating layer, a plurality of first temperature sensors are provided in the thermal insulation layer, and a plurality of second temperature sensors are provided in the road surface layer. In this solution, a snowmelt layer is laid on the highway, and the snowmelt layer mainly generates heat by the internal heating layer to melt the snow on the surface of the highway, wherein a road surface layer is laid on the heating layer, and the road surface layer is paved with asphalt, and the road surface layer can protect the heating layer, and the thermal insulation layer at the bottom of the heating layer can insulate the heat generated by the heating layer, and prevent the heat from being conducted to the ground and lost, resulting in reduced snow removal efficiency. The first temperature sensor and the second temperature sensor can respectively detect the temperature in the thermal insulation layer and the temperature in the road surface layer, and are used to transmit temperature signals to the control system, so as to timely control the heating work of the heating layer.

[0006] Preferably, it also includes an adhesive layer, which is arranged above the base layer, a leveling layer is arranged above the adhesive layer, and a snow melting layer is arranged above the leveling layer. The adhesive layer provides preliminary protection for the upper structure and strengthens the ground foundation, seals water vapor, penetrates the tiny gaps in the ground, creates a better adhesion interface for the subsequent coating structure, improves the bonding strength with the upper coating structure, and reduces the adverse factors that may occur in the subsequent construction. The leveling layer has excellent crack resistance and impact resistance, and provides a flat adhesion base surface for leveling the upper layer structure, making the subsequent layer structure more flat, and plays an important role in compression resistance, crack resistance and enhancement.

[0007] Preferably, the insulation layer and the heating layer are both made of asparagine polyurea material and its derivative application materials. Asparagine polyurea material has the advantages of high strength, high toughness, good impact resistance and crack resistance, and can effectively reduce the damage and replacement frequency of the heating layer, thereby reducing the use cost.

[0008] Preferably, the heating layer is provided with a plurality of parallel distributed carbon heating fillers, and the carbon heating fillers are connected in parallel in the circuit. The heating element in the heating layer is a carbon heating filler, which has the characteristics of low power consumption, low cost, and high heating efficiency, and is suitable for application scenarios requiring rapid heating and uniform heating distribution. In addition, the carbon heating filler also has good flexibility and dynamic stability, and has the advantages of being environmentally friendly and non-toxic.

[0009] Preferably, the first temperature sensors are evenly spaced in the insulation layer, and the second temperature sensors are evenly spaced in the pavement layer. The first temperature sensors are spaced in the insulation layer to detect the temperature of each position in the insulation layer, so as to timely feedback the real-time temperature inside the layer structure. Similarly, the second temperature sensors are spaced in the pavement layer to detect the temperature of each position in the pavement layer, so as to timely feedback the real-time temperature of the pavement.

[0010] A road snow removal method is implemented using the above-mentioned heating floor structure system, and also includes a temperature control device, the heating layer is electrically connected to the temperature control device, the temperature control device is connected to a distribution box, and the distribution box is connected to a wind and solar power generation machine and a power grid; a first temperature sensor and a second temperature sensor transmit the temperature signal of the snow melting layer to the temperature control device, and the temperature control device controls the heating layer to generate heat. In this solution, the heating work of the heating layer is controlled by the temperature control device, and the distribution box and the power grid provide energy for the temperature control device and the heating layer, etc., providing energy guarantee for snow removal.

[0011] Preferably, the carbon-based heating fillers are distributed in a curved shape, and are divided into K groups, wherein the serial numbers of the carbon-based heating fillers in the Kth group are K(n-1)+1, K(n-1)+2, …, K(n-1)+K; K≥2, n≥1, K and n are both integers. In this solution, the carbon-based heating fillers are distributed in a curved shape, which can increase the length of the heating element as a whole, thereby effectively increasing the heat generated by the heating element and improving the snow removal efficiency. The carbon-based heating fillers are also divided into several groups, and the carbon-based heating fillers in each group are staggered and distributed at intervals from each other, so that on the one hand, the heating of the heating layer can be made more uniform, and on the other hand, the effect of graded heating can be achieved, which effectively utilizes energy and reduces energy consumption.

[0012] Preferably, the temperature control device has K temperature intervals, and when the temperature signal received by the temperature control device is in the Kth temperature interval, the Kth group of carbon-based heating fillers enters the heating working state. When the road temperature drops to a certain range, ice and snow will accumulate on the road surface. At this time, it is necessary to start the corresponding heating element in the heating layer to work. The temperature of the road surface is gradually reduced, so the heating layer will start heating from the first group of carbon-based heating fillers, and finally start heating from the Kth group of carbon-based heating fillers to provide sufficient heat.

[0013] Preferably, the heating temperature range of the carbon heating material is between 40-80° C. Since the temperature detected by the sensor is the temperature in the road surface layer rather than the actual ice and snow temperature or outdoor temperature, the heating temperatures from the first group to the Kth group will be adjusted in real time to ensure timely heating and snow removal.

[0014] Preferably, the temperature signal received by the temperature control device is the average value of the temperatures detected by all the first temperature sensors and the average value of the temperatures detected by all the second temperature sensors. In order to ensure that the control of the temperature control device is more stable and accurate, the temperature signal received by the temperature control device needs to be the average value of the temperatures detected by all the first temperature sensors and the average value of the temperatures detected by all the second temperature sensors.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) the heating layer is evenly arranged on the road, which can improve the efficiency of road snow removal; (2) the snow removal method adopts a graded manner, and snow is removed according to the corresponding road snow conditions, which reduces unnecessary energy consumption, saves labor costs and improves the efficiency of snow and ice removal; (3) it is environmentally friendly and non-toxic, and improves the safety of road traffic in rainy and snowy weather.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0022] Example 1: Figure 1 to Figure 2A heating floor system shown in the figure includes a base layer 1, and above the base layer 1 are a bonding layer 8, a leveling layer 7 and a snowmelt layer from bottom to top; the snowmelt layer includes a thermal insulation layer 2, a heating layer 3 and a pavement layer 4 from bottom to top; the bonding layer 8 provides preliminary protection for the upper structure and strengthens the ground foundation, seals water vapor, penetrates the tiny gaps in the ground, creates a better adhesion interface for the subsequent coating structure, improves the bonding strength with the upper coating structure, and reduces the adverse factors that may occur in the subsequent construction. The leveling layer 7 has excellent crack resistance and impact resistance, and provides a flat adhesion base surface for the upper layer structure, making the subsequent layer structure more flat, and plays an important role in compression resistance, crack resistance and enhancement. Among them, the bonding layer 8 is generally laid between 0.2 and 0.4 mm, the leveling layer 7 is laid between 1.0 and 1.2 mm, the thermal insulation layer 2 is laid between 1.0 and 1.5 cm, the heating layer 3 is laid between 1.2 and 1.5 mm, and the pavement layer 4 is laid between 4.0 and 6.0 cm.

[0023] The snow melting layer mainly generates heat by the internal heating layer 3 to melt the snow on the road surface. A pavement layer 4 is laid on the heating layer 3 to protect the heating layer 3. The thermal insulation layer 2 at the bottom of the heating layer 3 can insulate the heat generated by the heating layer 3 to prevent the heat from being conducted to the ground and lost, which would reduce the snow removal efficiency.

[0024] A first temperature sensor 5 is provided in the thermal insulation layer 2, and there are a plurality of first temperature sensors 5, which are evenly laid in the thermal insulation layer 2. A second temperature sensor 6 is provided in the pavement layer 4, and there are a plurality of second temperature sensors 6, which are evenly laid in the pavement layer 4. The first temperature sensor 5 is mainly used to detect the temperature in the thermal insulation layer 2, and feed back the real-time temperature of the thermal insulation layer 2 to the temperature control device 10, which plays a role of feedback regulation for the temperature control device 10; the second temperature sensor 6 is mainly used to detect the temperature in the pavement layer 4, and feed back the real-time temperature of the pavement layer 4 to the temperature control device 10, which plays a role of feedback regulation for the temperature control device 10.

[0025] Specifically, the pavement layer 4 is located at the top and is in direct contact with the accumulated snow, while the insulation layer 2 is located at the bottom of the heating layer 3. Therefore, the temperature value detected by the second temperature sensor 6 located in the pavement layer 4 will be lower than the temperature value detected by the first temperature sensor 5 located in the insulation layer 2, so that there will be a temperature difference between the two. In the actual snow removal process, the snow water temperature is generally below zero degrees Celsius, so the temperature detected by the second temperature sensor 6 will be lower than zero degrees Celsius, and the temperature at the bottom of the heating layer 3 will be retained by the insulation layer 2, so that the temperature in the insulation layer 2 will be greater than zero degrees Celsius; when the temperature detected by the second temperature sensor 6 is greater than 0°C, it indicates that the pavement (the surface of the pavement layer 4) is in a rainwater state, and no snow or ice has been formed. At this time, the heating layer 3 does not perform heating work; when the temperature detected by the second temperature sensor 6 is less than 0 degrees Celsius, This indicates that the road surface (surface of the road surface layer 4) has accumulated snow or has become frozen. At this time, the signal is transmitted to the temperature control device 10, and the temperature control device 10 starts the heating layer 3 to perform heating work and starts snow and ice removal operations; at this time, the first temperature sensor 5 will also detect the temperature in the insulation layer 2 in real time. The temperature detected by the first temperature sensor 5 is generally greater than 0°C during the snow removal process. If the temperature detected by the first temperature sensor 5 is too low, it indicates that the heating layer 3 is insufficient in heat supply. The temperature signal of the first temperature sensor 5 is fed back to the temperature control device 10, and the temperature control device 10 controls the heating layer 3 to increase the output heat; if the temperature detected by the first temperature sensor 5 is too high (far greater than 0°C), it indicates that the heating layer 3 is overheated. The temperature signal of the first temperature sensor 5 is fed back to the temperature control device 10, and the temperature control device 10 controls the heating layer 3 to reduce the output heat.

[0026] The heating layer 3 has a number of heating elements, which are carbon heating fillers 11. The carbon heating fillers 11 mainly include carbon-based materials, such as carbon nanotubes, carbon fibers, graphene, etc. It has unique physical and chemical properties and can improve the thermal conductivity and electrothermal performance of the material. The carbon heating filler 11 also has the characteristics of rapid heating performance and low driving voltage, and has good flexibility and dynamic stability. Specifically, the carbon heating filler 11 can be made of a UV-cured conductive graphene coating disclosed in Patent No. CN114716905B or combined with asparagine polyurea material.

[0027] Several strips of carbon-based heating fillers 11 are provided, and all of the carbon-based heating fillers 11 are arranged in parallel in the circuit. Similarly, the carbon-based heating fillers 11 are evenly distributed in the heating layer 3. The carbon-based heating fillers 11 are laid out in strips and arranged in parallel. Arranging each carbon-based heating filler 11 in parallel can ensure the heating effect of the carbon-based heating filler 11. When one of the carbon-based heating fillers 11 is damaged, it will not affect the heating work of the remaining carbon-based heating fillers 11, and can ensure uniform heating of the heating layer 3.

[0028] It should be noted that in this solution, the bonding layer 8, the leveling layer 7, the insulation layer 2, and the heating layer 3 are all made of asparagine polyurea materials. The insulation layer 2 is foamed from asparagine polyurea resin coating. The specific technology can refer to a PAE polyurea foamed flame-retardant thermal insulation high-strength coating disclosed in patent number CN113150662B, or the formula can be optimized and adjusted, which has good thermal insulation effect, flame retardant and fireproof properties, and high strength and hardness; the specific material in the leveling layer 7 can refer to or adopt a coating made of a polyaspartic acid ester disclosed in patent number CN113548974A; the specific material in the bonding layer 8 can refer to or adopt a coating made of a low-viscosity and high-permeability polyaspartic acid ester disclosed in patent number CN113354792B. Asparagine polyurea material has the advantages of high strength, high toughness, good impact resistance and crack resistance, and can effectively reduce the damage and replacement frequency of the heating layer, thereby reducing the cost of use.

[0029] Specifically, firstly, an adhesive layer 8 is laid on the base layer 1, and then a leveling layer 7 is laid on the adhesive layer 8, and then an insulation layer 2 is laid on the leveling layer 7; in the process of the insulation layer 2, a plurality of first temperature sensors 5 are evenly inlaid and arranged inside the insulation layer 2, and the wire of each first temperature sensor 5 is exposed and connected to the temperature control device 10; copper foil wires are arranged at intervals on the upper surface of the insulation layer 2, and then carbon heating fillers 11 are evenly coated, and one end of each copper foil wire is fixedly connected with a spiral joint, and the spiral joint is connected to the temperature control device 10; the temperature control device 10 is connected to the distribution box 9 through the wire, and the distribution box 9 is connected to the wind and solar power generation machine 13 and the power grid 12; in the heating layer 3 The upper surface is paved with a pavement layer 4, and then a plurality of second temperature sensors 6 are installed at equal intervals in the pavement layer 4, and each second temperature sensor 6 is connected to the temperature control device 10 through a wire; the first temperature sensor 5 detects and feeds back the temperature near the insulation layer 3 in real time, that is, the temperature inside the layer structure, and the second temperature sensor 6 detects and feeds back the temperature of the pavement layer 4 in real time, that is, the temperature on the outer surface of the layer structure. Both the first temperature sensor 5 and the second temperature sensor 6 transmit the real-time temperature to the temperature control device 10. When the temperature is lower than the set threshold temperature, the temperature control device 10 controls the heating layer 3 to start working and generate heat energy, and when the temperature is higher than the set threshold temperature, the temperature control device 10 controls the heating layer 3 to stop working. When the heating layer 3 stops working and the ice and snow on the road surface melt into water, manual work is arranged to sweep and remove water from the surface water on the road surface to prevent the water from freezing into ice on the road surface again due to the low temperature, which will affect the road surface condition again.

[0030] It should be noted that the heating layer 3 can heat within a range of 40°C to 80°C under the real-time control of the temperature control device 10. In the process of handling ice and snow on the road, the high efficiency of technology and the initiative of human labor are organically combined, thus complementing each other and solving the problem of removing ice and snow on the road.

[0031] Example 2: Figure 1 , Figure 3 A heating floor structure shown includes a base layer 1, and above the base layer 1 are a bonding layer 8, a leveling layer 7 and a snowmelt layer from bottom to top; the snowmelt layer includes a thermal insulation layer 2, a heating layer 3 and a pavement layer 4 from bottom to top; the bonding layer 8 provides preliminary protection for the upper structure and strengthens the ground foundation, seals water vapor, penetrates the tiny gaps in the ground, creates a better adhesion interface for the subsequent coating structure, improves the bonding strength with the upper coating structure, and reduces the adverse factors that may occur in the subsequent construction. The leveling layer 7 has excellent crack resistance and impact resistance, and provides a flat adhesion base surface for the upper layer structure, making the subsequent layer structure more flat, and plays an important role in compression resistance, crack resistance and enhancement. Among them, the bonding layer 8 is generally laid between 0.2 and 0.4 mm, the leveling layer 7 is laid between 1.0 and 1.2 mm, the thermal insulation layer 2 is laid between 1.0 and 1.5 cm, the heating layer 3 is laid between 1.2 and 1.5 mm, and the pavement layer 4 is laid between 4.0 and 6.0 cm.

[0032] The snowmelt layer mainly generates heat by the internal heating layer 3 to melt the snow on the road surface. The snowmelt layer includes an insulation layer 2, a heating layer 3 and a pavement layer 4 from bottom to top. The pavement layer 4 is laid on the upper side of the heating layer 3 to protect the heating layer 3. The insulation layer 2 at the bottom of the heating layer 3 can keep the heat generated by the heating layer 3 warm and prevent the heat from being conducted to the ground and lost, which would reduce the snow removal efficiency.

[0033] A first temperature sensor 5 is provided in the thermal insulation layer 2, and there are a plurality of first temperature sensors 5, which are evenly laid in the thermal insulation layer 2. A second temperature sensor 6 is provided in the pavement layer 4, and there are a plurality of second temperature sensors 6, which are evenly laid in the pavement layer 4. The first temperature sensor 5 is mainly used to detect the temperature in the thermal insulation layer 2, and feed back the real-time temperature of the thermal insulation layer 2 to the temperature control device 10, which plays a role of feedback regulation for the temperature control device 10; the second temperature sensor 6 is mainly used to detect the temperature in the pavement layer 4, and feed back the actual temperature of the thermal insulation layer 2 to the temperature control device 10, which plays a role of direct regulation for the temperature control device 10.

[0034] Specifically, the pavement layer 4 is located at the topmost position of the base layer 1 and is in direct contact with the accumulated snow, while the thermal insulation layer 2 is located at the bottom position of the heating layer 3. Therefore, the temperature value detected by the second temperature sensor 6 located in the pavement layer 4 will be lower than the temperature value detected by the first temperature sensor 5 located in the thermal insulation layer 2, so that there will be a temperature difference between the two. In the actual snow removal process, the snow water temperature is generally below zero degrees Celsius, so the temperature detected by the second temperature sensor 6 will be lower than zero degrees Celsius, and the temperature at the bottom of the heating layer 3 will be retained by the thermal insulation layer 2, so that the temperature in the thermal insulation layer 2 will be greater than zero degrees Celsius; when the temperature detected by the second temperature sensor 6 is greater than 0°C, it indicates that the pavement (the surface of the pavement layer 4) is in a rainwater state and no snow or ice has been formed. At this time, the heating layer 3 does not perform heating work; when the temperature detected by the second temperature sensor 6 is less than When the temperature is 0 degrees Celsius, it indicates that the road surface (surface of the road surface layer 4) has accumulated snow or has become frozen. At this time, the signal is transmitted to the temperature control device 10, and the temperature control device 10 starts the heating layer 3 to perform heating work and starts snow and ice removal operations; at this time, the first temperature sensor 5 will also detect the temperature in the insulation layer 2 in real time. The temperature detected by the first temperature sensor 5 is generally greater than 0°C during the snow removal process. If the temperature detected by the first temperature sensor 5 is too low, the heat supply of the surface heating layer 3 is insufficient, and the temperature signal of the first temperature sensor 5 is fed back to the temperature control device 10, and the temperature control device 10 controls the heating layer 3 to increase the output heat; if the temperature detected by the first temperature sensor 5 is too high, it indicates that the heating layer 3 has excessive heat supply, and the temperature signal of the first temperature sensor 5 is fed back to the temperature control device 10, and the temperature control device 10 controls the heating layer 3 to reduce the output heat.

[0035] The heating layer 3 has a number of heating elements, which are carbon heating fillers 11. The carbon heating fillers 11 mainly include carbon-based materials, such as carbon nanotubes, carbon fibers, graphene, etc. It has unique physical and chemical properties and can improve the thermal conductivity and electrothermal performance of the material. The carbon heating filler 11 also has the characteristics of rapid heating performance and low driving voltage, and has good flexibility and dynamic stability. Specifically, the carbon heating filler 11 can be made of a UV-cured conductive graphene coating disclosed in Patent No. CN114716905B or combined with asparagine polyurea material.

[0036] Several strips of carbon heating fillers 11 are provided, and all carbon heating fillers 11 are arranged in parallel in the circuit. The carbon heating fillers 11 are divided into two groups, and the two groups of carbon heating fillers 11 are distributed in parallel in different circuits. The two groups of carbon heating fillers 11 are staggered together. Similarly, the carbon heating fillers 11 are evenly distributed in the heating layer 3. The carbon heating fillers 11 are laid in strips and arranged in parallel. The parallel arrangement of each carbon heating filler 11 can ensure the heating effect of the carbon heating filler 11. When one of the carbon heating fillers 11 is damaged, it will not affect the heating work of the remaining carbon heating fillers 11, and can ensure the uniform heating of the heating layer 3. Among them, the carbon heating filler 11 is also in a curved state, which can increase the length of the heating body to a certain extent, improve the heating effect, and is more conducive to the heating layer 3 to provide heat.

[0037] In addition, when two groups of carbon-based heating fillers 11 are used, graded heating operations can be performed. When the amount of snow is small, only the first group of carbon-based heating fillers 11 can be used for heating to reduce electricity consumption. When the amount of snow is large, the second group of carbon-based heating fillers 11 can be started for heating.

[0038] It should be noted that in this solution, the bonding layer 8, the leveling layer 7, the insulation layer 2, and the heating layer 3 are all made of asparagine polyurea materials. The insulation layer 2 is foamed from asparagine polyurea resin coating. The specific technology can refer to a PAE polyurea foamed flame-retardant thermal insulation high-strength coating disclosed in patent number CN113150662B, or the formula can be optimized and adjusted, which has good thermal insulation effect, flame retardant and fireproof properties, and high strength and hardness; the specific material in the leveling layer 7 can refer to or adopt a coating made of a polyaspartic acid ester disclosed in patent number CN113548974A; the specific material in the bonding layer 8 can refer to or adopt a coating made of a low-viscosity and high-permeability polyaspartic acid ester disclosed in patent number CN113354792B. Asparagine polyurea material has the advantages of high strength, high toughness, good impact resistance and crack resistance, and can effectively reduce the damage and replacement frequency of the heating layer, thereby reducing the cost of use.

[0039] Specifically, firstly, an adhesive layer 8 is laid on the base layer 1, and then a leveling layer 7 is laid on the adhesive layer 8, and then an insulation layer 2 is laid on the leveling layer 7; in the process of the insulation layer 2, a plurality of first temperature sensors 5 are evenly inlaid and arranged inside the insulation layer 2, and the wire of each first temperature sensor 5 is exposed and connected to the temperature control device 10; copper foil wires are arranged at intervals on the upper surface of the insulation layer 2, and then carbon heating fillers 11 are evenly coated, and one end of each copper foil wire is fixedly connected with a spiral joint, and the spiral joint is connected to the temperature control device 10; the temperature control device 10 is connected to the distribution box 9 through the wire, and the distribution box 9 is connected to the wind and solar power generation machine 13 and the power grid 12; in the heating layer 3 The upper surface is paved with a pavement layer 4, and then a plurality of second temperature sensors 6 are installed at equal intervals in the pavement layer 4, and each second temperature sensor 6 is connected to the temperature control device 10 through a wire; the first temperature sensor 5 detects and feeds back the temperature near the insulation layer 3 in real time, that is, the temperature inside the layer structure, and the second temperature sensor 6 detects and feeds back the temperature of the pavement layer 4 in real time, that is, the temperature on the outer surface of the layer structure. Both the first temperature sensor 5 and the second temperature sensor 6 transmit the real-time temperature to the temperature control device 10. When the temperature is lower than the set threshold temperature, the temperature control device 10 controls the heating layer 3 to start working and generate heat energy, and when the temperature is higher than the set threshold temperature, the temperature control device 10 controls the heating layer 3 to stop working. When the heating layer 3 stops working and the ice and snow on the road surface melt into water, manual work is arranged to sweep and remove water from the surface water on the road surface to prevent the water from freezing into ice on the road surface again due to the low temperature, which will affect the road surface condition again.

[0040] It should be noted that the heating layer 3 can heat within a range of 40°C to 80°C under the real-time control of the temperature control device 10. In the process of handling ice and snow on the road, the high efficiency of technology and the initiative of human labor are organically combined, thus complementing each other and solving the problem of removing ice and snow on the road.

[0041] Example 3: Figure 1 , Figure 3 as well as Figure 4The road snow removal method shown includes the following steps: first, laying an adhesive layer 8 on a base layer 1, then laying a leveling layer 7 on the adhesive layer 8, and then laying an insulation layer 2 on the leveling layer 7; in the process of the insulation layer 2, a plurality of first temperature sensors 5 are evenly inlaid and arranged inside the insulation layer 2, and the wire of each first temperature sensor 5 is exposed and connected to a temperature control device 10; copper foil wires are arranged at intervals on the upper surface of the insulation layer 2, and then carbon-based heating fillers 11 are evenly coated, and one end of each copper foil wire is fixedly connected with a spiral joint, and the spiral joint is connected to the temperature control device 10; the temperature control device 10 is connected to a distribution box 9 through a wire, and the distribution box 9 is connected to a wind and solar power generation machine 13 and a power grid 12 ; The pavement layer 4 is laid on the upper surface of the heating layer 3, and then a plurality of second temperature sensors 6 are installed at equal intervals in the pavement layer 4, and each second temperature sensor 6 is connected to the temperature control device 10 through a wire; the first temperature sensor 5 detects and feeds back the temperature near the insulation layer 3 in real time, that is, the temperature inside the layer structure, and the second temperature sensor 6 detects and feeds back the temperature of the pavement layer 4 in real time, that is, the temperature on the outer surface of the layer structure. Both the first temperature sensor 5 and the second temperature sensor 6 transmit the real-time temperature to the temperature control device 10. When the temperature is lower than the set threshold temperature, the temperature control device 10 controls the heating layer 3 to start working and generate heat energy. When the temperature is higher than the set threshold temperature, the temperature control device 10 controls the heating layer 3 to stop working. When the heating layer 3 stops working and the ice and snow on the road surface melt into water, manual work is arranged to sweep and remove water from the surface water on the road surface to prevent the water from freezing into ice on the road surface again due to the low temperature, which will affect the road surface condition again.

[0042] In order to achieve better snow removal efficiency and reduce snow removal energy consumption, snow removal adopts a graded heating mode. Specifically, the carbon-based heating filler is divided into K groups, which can be two groups, three groups or four groups, and generally not more than 4 groups. Figure 3 As shown, in this embodiment, the carbon-based heating fillers are divided into two groups, that is, K=2, and then the carbon-based heating fillers arranged side by side are numbered, wherein the carbon-based heating materials of the first group are 1 / 3 / 5 / 7... respectively; the carbon-based materials of the second group are 2 / 4 / 6 / 8... respectively; the carbon-based heating materials of the first group are evenly spaced, and the carbon-based materials of the second group are evenly spaced, and the first and second groups of carbon-based materials are staggered together. When the amount of snow accumulation is small, only the first group of carbon-based heating fillers 11 can be used for heating to reduce power consumption, and when the amount of snow accumulation is large, the second group of carbon-based heating fillers 11 can be started for heating. That is, feedback adjustment can be performed through the first temperature sensor 5.

[0043] When the temperature detected by the second temperature sensor 6 is greater than 0°C, it indicates that the road surface (surface of the road surface layer 4) is in a rainy state, and no snow or ice has been formed. At this time, the heating layer 3 does not perform heating work; when the temperature detected by the second temperature sensor 6 is between -3°C and 0°C, it indicates that the road surface (surface of the road surface layer 4) has snow or has become an ice state. At this time, the signal is transmitted to the temperature control device 10, and the temperature control device 10 starts the first group of carbon heating fillers 11 of the heating layer 3 to perform heating work and start snow and ice removal operations. In the state of heating work startup, when the temperature detected by the second temperature sensor is between 5°C and 8°C, it indicates that there is too much snow, and the temperature signal is transmitted to the temperature control device 10, and the temperature control device 10 starts the second group of carbon heating fillers 11 of the heating layer 3 to perform heating work, thereby improving the heating work efficiency and the snow removal efficiency. It should be noted that the temperature signal transmitted to the temperature control device 10 is the average value of the temperatures detected by all the second temperature sensors 6, ensuring that the control of the temperature control device 10 is more stable and accurate. When multiple groups (K>2) of carbon-based heating fillers 11 are used for heating, the starting temperature range from the 2nd to the Kth decreases step by step. For example, if three groups of carbon-based heating fillers 11 are used, the temperature of the third group of heating elements needs to be started between 3°C and 5°C. If four groups of carbon-based heating fillers 11 are used, the temperature of the fourth group of heating elements needs to be started between 2°C and 3°C to ensure that the heating value is adapted to the amount of snow.
