Embodiment 1

[0030] This embodiment provides a plug-in road ice and snow melting heat pipe, such as figure 1 As shown, it includes a lower heat pipe 1 , an upper heat pipe 2 and a plug-in heat exchange structure 3 , and the lower heat pipe 1 and upper heat pipe 2 are connected through the plug-in heat exchange structure 3 .

[0031] The lower heat pipe 1 is a complete heat pipe made of cold-drawn (rolled) seamless steel pipe, and its interior is a cavity. The lower heat pipe 1 is provided with a gaseous inorganic heat-conducting medium 3-2 inside, and the lower heat pipe 1 has a complete evaporation section, a conveying section and a condensation section.

[0032] The lower heat pipe 1 is divided into upper and lower parts, and its lower part is an evaporation section and a delivery section with a tubular structure of equal diameter, which are used to absorb and transport geothermal heat. The upper part of the lower heat pipe 1 has a condensing section with a circular platform structure, ...

Embodiment 2

[0042] This embodiment provides a construction method of a plug-in road ice and snow melting heat pipe. The main implementation process is: fixed-point setting out→drilling→lifting, installation, and fixing of the lower heat pipe 1→refilling and maintenance of cement mortar in the evaporation section of the lower heat pipe 1 →The upper heat pipe 2 is in place and the plug-in heat exchange structure 3 is connected →Adjust the telescopic adjustment device 4 of the conveying section of the upper heat pipe 4, and make the elevation and slope of the condensation section of the upper heat pipe 2 meet the design requirements →Fix the upper heat pipe 2 →Apply the lower heat pipe 1 Insulation of the transmission section, plug-in heat exchange structure 3 and upper heat pipe 2 transmission section → backfilling and maintenance of the condensation section of the upper heat pipe 2 → construction of the upper pavement structure.

[0043] In addition, in order to avoid causing troubles to th...

Abstract

The invention discloses a plug-in type road ice and snow melting heat pipe and a construction method thereof. The heat pipe is characterized by comprising a lower heat pipe and an upper heat pipe, wherein the lower heat pipe and the upper heat pipe are connected through a plug-in heat exchange structure; and the plug-in heat exchange structure is formed by inserting a lower heat pipe condensationsection and an upper heat pipe evaporation section. According to the heat pipe, the problems that the maintenance of the road provided with the heat pipe is difficult and the heat pipe cannot be reused are solved, and the maintenance cost of the hot pipe road surface is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of road ice and snow removal, in particular to a plug-in heat pipe for melting ice and snow on roads and a construction method. Background technique [0002] Rain and snow disasters in winter increase the probability of road traffic congestion and traffic accidents, and bring great safety hazards and huge economic losses to expressway operations. At the same time, rainwater infiltrates into the pavement and causes frost heave, which also seriously affects the service life of the pavement. [0003] The prior art discloses a heat pipe-type geothermal snow-melting structure, which uses the vertical evaporation section of the heat pipe to collect the geothermal heat in the underground rock and soil layer, and transfers it to the horizontal condensation section buried in the ground through the conveying section, so as to realize the green active melting of ice and snow on the ground. It embeds the horizontal con...
