specific Embodiment approach 1
[0028] Specific implementation mode 1: An intelligent control electric heating road surface deicing and snowing process of this embodiment, for asphalt pavement, the described deicing and snowing process is completed by the following steps:
[0029] 1. Embed heating ribs in the asphalt pavement; the specific embedding steps are as follows:
[0030] a. Treat the underlayment at 5cm-7cm below the road surface: for the newly paved asphalt pavement, use a road roller to level it; for the old road surface, level it by milling or use new asphalt concrete to level it ;
[0031] b. Spread sticky layer oil: spread a layer of sticky layer oil on the lower bearing layer treated in step 1 (strengthening interlayer bonding);
[0032] In this embodiment, the viscous layer oil can be liquid asphalt or emulsified asphalt, if the underlying layer is an asphalt layer, the amount of liquid asphalt is 0.3L / m 3 ~0.5L / m 3 , the amount of emulsified asphalt is 0.3L / m 3 ~0.6L / m 3 ; If the underl...
specific Embodiment approach 2
[0040] Specific embodiment 2: In this embodiment, in step 1-c, the distance between two adjacent steel bars is 15cm-20cm (used to fix the heating bars). This can not only avoid the waste of resources caused by too dense steel mesh, but also avoid the uneven heat dissipation of the heating ribs caused by too thin steel mesh, and it is also conducive to the interlayer bonding of the road surface. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0041] Specific embodiment three: In the c of step one in this embodiment, the steel mesh is fixed on the road surface that is sprinkled with sticky layer oil with several steel nails through the nodes of the steel mesh, and the distance between two adjacent steel nails is adjacent. An integer multiple of the spacing between two steel bars. So designed, the nodes of the steel mesh can be fixed to effectively stabilize the steel mesh on the road. Other steps are the same as in the first embodiment.

Abstract
The invention discloses an intelligent controlled electric heating pavement ice and snow removing process, and relates to an electric heating pavement ice and snow removing process. The process solves the problems of pavement corrosion and water resource pollution easily caused in chemical ice and snow removal, high investment in mechanical ice and snow removal and high energy consumption in traditional electric heating. The first scheme comprises that heating ribs are embedded into an asphalt pavement, and specifically the process comprises the following steps of: treating a lower bearing layer in 5 to 7 centimeters below the pavement, scattering adhesive oil, paving a reinforcement fabric, pre-treating the heating ribs, binding the heating ribs and a pavement temperature sensor, mechanically spreading concrete, and curing the pavement; arranging an atmospheric temperature sensor and an intelligent temperature controller; and setting intelligent temperature control parameters. The second scheme comprises that heating ribs are embedded into a cement pavement, and specifically the process comprises the following steps of: treating a lower bearing layer in 5 to 7 centimeters below the pavement, paving a reinforcement fabric, binding strutting pieces, pre-treating the heating ribs, binding the heating ribs and a pavement temperature sensor, mechanically spreading concrete, and curing the pavement. The other schemes are the same. The process is used for ice and snow removal of the pavement.
Description
technical field [0001] The invention relates to an electric heating type road surface deicing and snow removal process, which belongs to the technical field of road surface maintenance. Background technique [0002] The minimum temperature of the road surface in subtropical regions will drop to about 0°C in winter, while the minimum temperature of the road surface on the mountainous road sections with higher altitudes and the road sections that are greatly affected by the cold air of the canyon can often reach below 0°C. Once there is rain or snowfall, these road sections are very easy to freeze. If there are no timely and appropriate measures to remove ice and snow, it will bring great hidden dangers to driving safety. At present, my country's road deicing technology mainly includes three categories: chemical deicing technology, mechanical deicing technology and physical deicing technology. The use of chemical deicing technology is likely to cause serious corrosion of the ...
