Abstract

The invention discloses a temperature strain monitoring system for a fluid heating snow melting pavement, and relates to the field of temperature strain monitoring of the fluid heating snow melting pavement. The invention solves the problem of pavement safety caused by the fact that traditional fluid heating snow melting pavement only pays attention to the snow melting effect and neglects the temperature strain generated by the heat flow impact action. The temperature strain monitoring system for a fluid heating snow melting pavement comprises a heating system, a circulating pump, an environment box, a pavement system and a monitoring system, wherein the heating system comprises a heating water tank, a distribution box and an electric heating pipe; the electric heating pipe is arranged inthe heating water tank; the pavement system is arranged in the environment box; the pavement system comprises a cement concrete pavement and a pipeline; the pipeline is horizontally embedded in the cement concrete pavement and is connected with the heating water tank through a connecting pipe; the connecting pipe is provided with the circulating pump and a control valve; a temperature sensor and aresistance strain gauge are arranged inside the cement concrete pavement; and a digital speckle instrument acquisition device is erected on one side of the cement concrete pavement. The invention isused for testing the temperature strain of the airport snow melting road surface.

Description

technical field [0001] The invention relates to the field of monitoring the temperature and strain of a fluid-heated snow-melting road surface, in particular to a temperature-strain monitoring system for a fluid-heated snow-melting road surface. Background technique [0002] Snow and ice removal from road surfaces has become a typical safety issue in airport operations. The traditional deicing methods for runways mainly use snow removal machinery and deicing salt. However, these two methods have low deicing efficiency when the temperature is low and the snowfall is large, and they have negative effects on the surface structure and the environment. [0003] At present, the circulating fluid heating system has become an effective alternative method for deicing and snowing the airport pavement. Its working principle is: use the circulating fluid to transfer the heat of the underground soil to the pipeline inside the pavement, and then transfer the heat to the surface through t...
