Problems solved by technology

The concrete resistivity of the conductive asphalt concrete method is not easy to control and is made very small. If the laying thickness is small, only the upper and lower power supply can ensure the safety of power supply, and the laying of metal mesh electrodes requires high flatness, and the construction is difficult
[0009] The heating cable method is to lay steel mesh first, and then fix the heating cable on the steel mesh. It is necessary to ensure the integrity of the insulation of the heating cable to ensure the effectiveness of heating and the safety of electricity. The installation is complicated and it is not suitable for large-scale mechanical paving.
[0010] Available prior art, such as publication number 101806028A discloses an invention patent of "layer-distributed steel fiber conductive asphalt concrete". The conductivity of conductive emulsified asphalt makes the pavement heat. In actual construction, the steel fiber is not easy to spread evenly, resulting in uneven resistance and uneven heating. It is also difficult to control the heating power of the pavement.
[0011] Another example is that the publication number is 101235621A, which discloses an invention patent of "electric heating for melting snow and ice on cement concrete bridge deck". This patent uses a silicone-covered carbon fiber heating wire, which is erected by a steel mesh. In actual construction, the laying is complicated and requires high insulation. , it is not easy to ensure the safety of electricity use, and it is not suitable for large-scale mechanical pavement

specific Embodiment approach

[0025] The implementation of the technical solution proposed by the present invention is to achieve the goals of simple construction, uniform heating and safe electricity use by rationally designing the resistance network structure, laying method and power supply mode. The specific implementation is as follows:

[0026] A resistance net facility for deicing and snowing on road surfaces, wherein the resistance net is laid between the road surface layer and the surface bearing layer or in the concrete surface layer, and the resistance net is a strip-shaped resistance wire 12 and a columnar metal fixed The distance rods 13 are welded in an orthogonal manner, the distance between the resistance wires 12 is 3~10cm, the distance between the metal distance rods 13 is 4~100cm, and the two ends of the resistance wire 12 are welded with copper wires or copper strips in the orthogonal direction constitute.

[0027] The laying method is that the direction of the resistance wire 12 in the...

Abstract

The invention discloses a resistance network facility for removing snows and ices from a road and a laying and power-supplying method thereof. The resistance network facility adopts the structure that a resistance network is laid between a surface layer and a surface bearing layer of the road, or inside the concrete surface layer; and the resistance network is formed by orthogonally welding belt-shaped resistance wires and cylindrical metal spacer bars and orthogonally welding copper wires at two ends of the directions of the resistance wires. The laying and power-supplying method comprises the following steps: along the directions of the resistance wires, dividing the resistance network into three sections or into the sections with the number of multiple of three along the running direction of vehicles on the road; suspending midpoints of three output phases of a power-supplying isolation transformer; and connecting a first output end U, a second output end V and a third output end W in the isolation transformer with ends of three sections of copper strips respectively. The resistance network facility can uniformly remove the snows and thaw the ices, is high in efficiency, good in stability, safe to use electricity and easy in laying, and is applicable to large-area laying and mechanical operation.

Description

technical field [0001] The invention relates to a heating structure for melting snow and ice on the road surface and a laying method thereof, in particular to a resistance network structure and a laying power supply method for melting snow and ice on the road surface by using a resistance network. Background technique [0002] Existing snow and ice removal equipment mainly includes snowplows, deicing vehicles and ice melting vehicles. Snow removal, deicing and ice melting are carried out through road surface operations. The workload of removing ice and snow is large and the efficiency is low; [0003] Existing methods for removing ice and snow mainly contain chemical ice and snow melting method and heating ice and snow melting method. [0004] The chemical ice and snow melting method is mainly to sprinkle deicing agent on the road before and after snowfall. Its main component is chlorine salt, which melts ice and snow quickly, but it seriously corrodes bridges, roads, vehicl...
