[0002] The ice and snow phenomenon in northern regions in winter has a great impact on the normal traffic on the roads. Snow and ice on the road often become one of the main causes of traffic jams and frequent accidents. Long-term ice and snow weather may even cause important transportation facilities such as airport runways, highways, and railways to be closed, seriously affecting people's normal travel and production and living needs.

[0003] Common methods for melting snow and ice on the road include manual or mechanical snow removal, chemical snow melting, geothermal method and electric heating method. Manual and mechanical snow removal requires a lot of manpower and material resources, and there is a lag, so it is difficult to quickly remove snow on the road. The chemical snow melting method refers to the use of snow melting agents to melt snow. Although snow melting agents have the advantages of being easy to use and economical, the use of snow melting agents will shorten the service life of the road, cause groundwater pollution, steel corrosion, and soil compaction. The carbon fiber heating cable snow melting technology melts ice and snow by heating the road surface. It has the characteristics of preheating the road surface in advance, fast and environmentally friendly, and has broad application prospects.

However, uneven glue coating is prone to occur during manufacturing, resulting in road leakage. In addition, the heating core is a continuous heating wire. In order to form a geogrid, the fiber bundle is a plurality of short wires, and adjacent fiber bundles are disconnected, resulting in cumbersome wiring of the geogrid.

In addition, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0025] Please also read Figures 1 to 3 , the hybrid heating geogrid provided by the present invention is now described. The hybrid heating geogrid includes a plurality of glass fiber bundles, a plurality of silicone wires 2 and a plurality of heating cables 3. The plurality of glass fiber bundles are arranged at intervals along the second installation direction, each glass fiber bundle extends along the first installation direction, each glass fiber bundle includes two twisted and connected glass fibers 1, and the first installation direction is perpendicular to the second installation direction; the plurality of silicone wires 2 are arranged at intervals along the first installation direction, each silicone wire 2 extends along the second installation direction, and the plurality of silicone wires 2 and the plurality of glass fibers 1 cross to form a mesh structure; each heating cable 3 is fixed on the mesh structure in a serpentine bending manner, and the plurality of heating cables 3 are spaced apart along the second installation direction, and the heating cable 3 includes a carbon fiber bundle 32 and an insulating sleeve 31 sleeved on the outer periphery of the carbon fiber bundle 32.

[0026] It should be noted that the heating cable 3 is arranged in a serpentine shape, and has multiple first cables extending along the second installation direction and second cables whose two ends are respectively connected to two adjacent first cables. The second cable is an arc cable. The multiple first cables are arranged at intervals along the first installation direction, and the multiple silicone wires 2 are arranged on the glass fiber at intervals along the first installation direction. The silicone wires 2 can cooperate with the glass fiber 1 to form a mesh structure to improve the stability of the heating cable 3.

[0027] In the specific implementation, the carbon fiber tow 32 adopts large tow carbon fiber, specifically 48k and above carbon fiber. After bending, the safety voltage adopted by the heating cable 3 is 48V, which reduces the potential safety hazard.

[0028] It should be noted that the silicone wire 2 inserted between two adjacent first cables reduces the usage of the heating cable 3 and saves the cost of raw materials.

[0029] It should be noted that the insulating sleeve 31 is a sleeve structure, which is stronger than the existing coating structure and will not cause uneven coverage.

[0030] It should be noted that Figure 1 The direction represented by the dotted arrow is the first installation direction. Figure 1 The direction represented by the solid arrow in FIG. 1 is the second installation direction.

[0031] The mixed heating geogrid provided in the present embodiment changes the assembly method of the geogrid compared with the prior art. The glass fiber 1 is used as the foundation, and the heating cable 3 is fixed on the glass fiber 1. The heating cable 3 is arranged in a snake shape, and the silicone wire 2 is arranged between adjacent heating cables 3 to form a grid-like grid structure. The glass fiber 1 and the silicone wire 2 are all inserted as a whole, with high structural strength and low installation difficulty, which is conducive to the assembly of the geogrid; the silicone wire 2 can cooperate with the glass fiber 1 to form a mesh structure, which improves the stability of use, and the heating cable 3 can be compactly bent, reducing the operating voltage and increasing work safety; the outer periphery of the heating cable 3 is provided with an insulating sleeve 4, and the insulating sleeve 4 has a wide coverage area, and there will be no uneven coverage phenomenon, which reduces the danger of use.

[0032] In some embodiments, see Figure 1 The two ends of the heating cable 3 are connected to the neutral wire and the live wire respectively, and the two ends of the heating cable 3 are located on the same side of the mesh structure. The carbon fiber tow 32 is energized to generate heat, and the two ends are connected to the neutral wire and the live wire respectively to connect the current and realize the heating function of the heating cable 3. The neutral wire and the live wire are arranged on the same side of the mesh structure, which is convenient for installation and reduces the difficulty of installation. The neutral wire and the live wire are arranged on the same side to reduce the occupied area. When laid on the road, the heating cable 3 can be repaired and connected on the same side of the mesh structure, which reduces the difficulty of repair and connection.

[0033] See also Figure 1 , the neutral wire is N and the live wire is L.

[0034] It should be noted that the two ends of the multiple heating cables 3 are connected to the neutral wire and the live wire respectively, and the multiple heating cables 3 are connected in parallel. After the multiple heating cables are connected in parallel, the heating of each heating cable 3 is not related. When one of the heating cables 3 is damaged and cannot work, the other heating cables 3 can work normally, reducing the impact on the snow removal of the road surface, and there will be no large-scale paralysis of the heating cables 3, which will affect the snow removal work of the road surface.

[0035] In some embodiments, see Figure 2 , a plurality of fixing holes 11 and a plurality of mounting holes 12 are formed between two glass fibers 1 in the same glass fiber bundle, and the plurality of fixing holes 11 and the plurality of mounting holes 12 are alternately arranged in sequence along the first installation direction, and the fixing holes 11 are plugged in with the silicone wire 2, and the mounting holes 12 are plugged in with the insulating sleeve 31. The arrangement of the fixing holes 11 and the mounting holes 12 enables the glass fiber 1 to be connected to the silicone wire 2 and the heating cable 3 as a whole, respectively, thereby improving the structural stability. The plug-in matching method improves the connection strength between the glass fiber 1 and the silicone wire 2, and at the same time improves the connection strength between the glass fiber 1 and the heating cable 3. After the silicone wire 2 and the heating cable 3 are respectively inserted into the glass fiber 1, they are limited in the first installation direction, and the silicone wire 2 and the heating cable 3 can only be inserted or withdrawn in the second installation direction, thereby reducing the difficulty of installation.

[0036] This embodiment provides a method for forming the fixing hole 11 and the mounting hole 12, using two glass fibers 1 stacked up and down, placing the silicone wire 2 and the heating cable 3 in corresponding positions, and twisting the two glass fibers 1 up and down. The two glass fibers 1 are quickly twisted together to form the fixing hole 11 and the mounting hole 12. The processing method is simple and fast, which improves the overall weaving speed. The fixing hole 11 and the mounting hole 12 are formed by two connecting wires, and there is no need to work on the glass fiber 1, which reduces the labor.

[0037] It should be noted that the existing connection method between the heating cable 3 and the glass fiber 1 is to tie the heating cable 3 to the glass fiber 1 with the help of wire fasteners. The present application opens a mounting hole 12 on the glass fiber 1, so that the heating cable 3 is installed through the mounting hole 12, thereby improving the connection integrity between the glass fiber 1 and the mounting hole 12.

[0038] In some embodiments, the spacing between adjacent fixing holes 11 and mounting holes 12 is the same, so that the corresponding silicone wires 2 and heating cables 3 are fixed with the same spacing, ensuring heating stability.

[0039] In some embodiments, the heating cable 3 further includes a graphene conductive material mixed in the carbon fiber tow 32. The graphene conductive material has high conductivity, ultra-high conductivity, and excellent thermal conductivity. The conductivity threshold of graphene is very low, and a small amount can improve the electrode performance. The carrier mobility of the graphene conductive material is 15000 cm² / Vs. The graphene conductive material is mixed in the carbon fiber tow 32, which greatly improves the conductivity of the carbon fiber tow 32, reduces the operating voltage, and improves the safety of use.

[0040] In a specific implementation, the graphene conductive material accounts for only 5% of the heating cable 3. The graphene conductive material and the carbon fiber tow 32 are evenly mixed.

[0041] In some embodiments, see Figure 1 , a node is formed between the glass fiber 1 and the silicone wire 2, and the hybrid heating geogrid also includes a plurality of fasteners 4, which correspond one to one to the nodes at the two ends of the mesh structure, and the fasteners 4 include binding belts, which connect the glass fiber 1 and the silicone wire 2. The fasteners 4 can bind and fix the silicone wires 2 and the corresponding plurality of glass fibers 1 at both ends of the mesh structure, perform preliminary fixation of the mesh structure, and facilitate twisting of the two connecting wires, so that the silicone wire 2 and the heating cable 3 can be fixed on the glass fiber 1. After the fasteners 4 are used, the plurality of glass fibers 1 can remain relatively fixed along the second installation direction, and will not move along the second installation direction when twisting, thereby reducing the difficulty of weaving.

[0042] In specific implementation, the binding belt is an insulating high temperature resistant binding belt. The heating cable 3 generates heat after being powered on. The high temperature resistance of the binding belt can extend the service life, extend the service life of the mesh structure, and reduce the number of inspections of the binding belt. The binding belt can initially fix multiple glass fibers 1 to facilitate the formation of the mesh structure.

[0043] In some embodiments, the outer periphery of the glass fiber 1 and the silicone wire 2 is coated with a protective layer. The protective layer can isolate the glass fiber 1 and the silicone wire 2, reduce the impact of the external environment on the glass fiber 1 and the silicone wire 2, prevent the glass fiber 1 and the silicone wire 2 from being eroded by wind and sand, and prevent the glass fiber 1 and the silicone wire 2 from being directly damaged by collision. The protective layer can extend the service life of the glass fiber 1 and the silicone wire 2, reduce the damage suffered, and improve the safety of use.

[0044] During specific implementation, a protective layer is also provided on the periphery of the heating cable 3, which reduces the impact of sand, gravel, rain and snow on the geogrid and improves the protective effect of the geogrid.

[0045] In some embodiments, the protective layer is formed by mixing white latex and emulsified asphalt mixed coating. After mixing, the white latex and emulsified asphalt mixed coating can form a hard and airtight protective shell that is corrosion-resistant and high-temperature-resistant, can shield debris from the geogrid, and reduce uncertainties.

[0046] Specifically, the emulsified asphalt, white latex and water of the present application are uniformly mixed in a ratio of 3:4:4, and the obtained protective layer is of high quality.

[0047] As a processing method for the protective layer of this embodiment, emulsified asphalt, white latex and water are evenly mixed in a ratio of 3:4:4, and then evenly mixed using a mixer, so that the mixed liquid is maintained at a certain temperature, the geogrid is completely immersed in the mixed liquid, and after being taken out, it is quickly dried to form a protective layer.

[0048] Based on the same inventive concept, the present application also provides a hybrid heating geogrid processing technology for manufacturing a hybrid heating geogrid as any of the above-mentioned embodiments, comprising the following steps: laying glass fiber 1, heating cable and glass fiber 1 in sequence from bottom to top, the heating cable is arranged in a serpentine shape, and the bottom layer of glass fiber 1, the heating cable and the top layer of glass fiber 1 respectively maintain a certain tension; twisting the two glass fibers 1 between the heating cables; inserting silicone wire 2 at the twisting point, so that the silicone wire 2 and the heating cable are arranged alternately in sequence; repeating the above steps to combine the glass fiber 1, the heating cable and the silicone wire 2 to form a grid mesh structure; coating the grid mesh structure.

[0049] The processing technology of the mixed heating geogrid provided in this embodiment changes the assembly method of the geogrid. The glass fiber 1 is used as the foundation, and the heating cable 3 is fixed on the glass fiber 1. The heating cable 3 is arranged in a snake shape. The silicone wire 2 is arranged between adjacent heating cables 3 to form a grid-like grid structure. The glass fiber 1 and the silicone wire 2 are all inserted as a whole, with high structural strength and low installation difficulty, which is conducive to the assembly of the geogrid; the silicone wire 2 can cooperate with the glass fiber 1 to form a mesh structure, which improves the stability of use. The heating cable 3 can be bent compactly, reduce the operating voltage, and increase work safety; the outer periphery of the heating cable 3 is sheathed with an insulating sleeve 4, and the insulating sleeve 4 has a wide coverage area, and there will be no uneven coverage phenomenon, which reduces the danger of use. By twisting the glass fiber 1 located in the upper and lower layers of the heating cable 3, the heating cable 3 is fixed between the two glass fibers 1, which improves the structural strength, the heating cable 3 will not be deformed, and the stability of use is improved; the setting of the coating can extend the service life and reduce the long-term production cost.

[0050] In some embodiments, see Figure 2The two glass fibers 1 in the same glass fiber bundle are twisted to form a storage space for the silicone wire 2, and the twisting direction of the storage space is opposite to the twisting direction of the glass fibers 1. The twisting direction is opposite, so that after the silicone wire 2 or the heating cable is inserted, the fixing hole 11 or the mounting hole 12 will not be deformed during use, thereby increasing the stability of use. And after the silicone wire 2 is inserted, the two twisted glass fibers 1 are always in a twisted state and will not recover.

[0051] The following is a specific processing method of the mixed heating geogrid provided by the present invention: Use an iron mold and brush release oil on it to facilitate the subsequent demoulding of the grille.

[0052] The glass fiber 1 is wound on the mold in sequence, and the tightening motor is started to maintain a certain tension.

[0053] The heating cable 3 is then wound on the glass fiber 1 in sequence, and the tension is also maintained by a tightening motor.

[0054] Then wind the glass fiber 1 around the heating cable 3 in the same manner as 2 .

[0055] A hollow metal tube is used to twist between two adjacent heating cables 3. After twisting, the silicone wire 2 is inserted into the metal tube, straightened and then withdrawn from the metal tube to complete the weaving work of one node.

[0056] Complete the mesh weaving work as described above.

[0057] Mix emulsified asphalt, white latex and water in a ratio of 3:4:4 and use a mixer to stir at a speed of 2300r / min for 5 minutes.

[0058] Pour the prepared mixed solution into the immersion tank and maintain the temperature at 40°C.

[0059] The woven grille and the mold are placed in a soaking tank, taken out and placed in a 145°C oven for baking for 5 minutes.

[0060] Take out the baked grid and apply polyethylene resin on its surface with a glue brush.

[0061] After drying, the heating grille is packaged and rolled to obtain the finished product.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
