Snow melting service life predicting device for salt self-snow-melting road surface

Abstract

The invention discloses a snow melting service life predicting device for a salt self-snow-melting road surface, and the snow melting service life predicting device comprises an environment box, and an environment regulating unit and a testing unit which are placed in the environment box. The environment regulating unit comprises a heating lamp, a tap water spraying head, a temperature detecting device, a refrigerating system arranged at the bottom of the environment box and a ventilating system arranged on the side surface of the environment box; the testing unit comprises an electromagnetic flow meter and a sampling hole on a water outlet pipe; a liquid holding container comprising a cover plate with a hole is placed below the sampling hole; and a density measuring instrument is arranged in the liquid holding container. By using the snow melting service life predicting device, the precipitation process of the effective components of the salt self-snow-melting road surface can be simulated, and the snow melting service life predicting device is mainly used for predicting the snow melting service life of the salt self-snow-melting road surface.

Description

technical field [0001] The present invention relates to highway pavement test technology, in particular to a self-melting snow-melting pavement snow-melting life simulation and prediction device, which can be applied to simulate the precipitation of active components of self-melting snow pavement in various natural environments (sunshine, icing, rain, wind) process, evaluate the long-term snow-melting performance of self-snow-melting pavement, and estimate the snow-melting life of self-snow-melting pavement. Background technique [0002] Snow and ice on roads in winter has always been a problem that plagues road traffic safety. It usually requires a lot of manpower and material resources to remove ice and snow, so research on actively suppressing frozen roads has also begun. Active anti-freezing technology is to actively adopt related technologies in advance or add special materials to the mixture during engineering construction or overhauling the road surface to make the ro...

Problems solved by technology

Domestic related research, for example, Chang’an University has developed a long-term snow-melting performance evaluation device for salt self-melting road surface, which simulates soaking the test piece in a constant temperature water bath. The concentration of salinity in the medium is continuously increasing, and the precipitation of salinity is inhibited, which cannot simulate the situation of running water washing the road surface in the natural environment
