Refined use method of snow-melting agent

Abstract

The invention discloses a refined use method of a snow-melting agent. The method comprises the following steps: firstly, through freezing point testing, solving an inverse function to obtain a function of the concentration C of the snow-melting agent solution relative to the temperature t; according to the relationship between the pavement snow-melting agent concentration C and the spreading areaS, the ice and snow thickness h, the ice and snow density rho and the spreading mass m of the snow-melting agent; and further deducing the relationship between the spreading mass m of the snow-meltingagent and the ice and snow thickness h as well as the external temperature t, i.e., accurately calculating the spreading amount of the snow-melting agent per kilometer according to the external environment temperature and weather conditions in winter. According to the invention, the problem that a road management and maintenance department cannot reasonably determine the spreading amount of the snow-melting agent according to the environment temperature and weather conditions is solved; the use amount of the snow melting agent used for snow removal in winter is reduced to a great extent, theroad maintenance cost is saved, the snow removal efficiency of the road in winter is improved, pollution to the surrounding environment of the road is reduced, and efficient, economical, environment-friendly and high-operability technical support is provided for a road management and maintenance department.

Description

technical field [0001] The invention belongs to the technical field of snow melting and deicing for urban roads, airport roads and highways, and in particular relates to a refined use method of snow melting agent. Background technique [0002] In most parts of our country, there will be road icing or snow accumulation in winter, especially when highways and urban roads are affected by ice and snow weather, not only will it cause traffic congestion, but also prone to traffic accidents, causing serious economic losses and property loss. Therefore, in order to ensure the smooth flow of the road and driving safety, it is necessary to remove the snow on the road in time and effectively. At present, the method of melting snow and deicing widely adopted in my country is exactly to spread deicing agent on the road. Compared with other snow removal methods, this method is easy to operate, has a wide source of snow removal materials, low cost, and significant snow melting and deicin...

Problems solved by technology

Although this patent can determine the amount of de-icing and snow-melting agent that should be used on icy roads under different external temperatures, different wind speeds, and different ice thicknesses, etc., it limits the ice layer and the bottom of the salt solution layer during the ice-melting process. Consistent, the thickness of the deicing salt to be used is mainly determined according to the thickness of the ice layer, and the amount of deicing agent and the driving speed of the deicing agent spreading vehicle cannot be accurately obtained

Patent CN201910242841.6 discloses a road icing early warning and automatic disposal system control method. First, the icing trend is estimated according to the early warning information, and then the amount of deicing agent spraying, spraying interval and spraying time are adjusted according to the current meteorological data and road surface conditions. The number of times; the amount of deicing agent sprayed at one time is set according to the coefficient of performance of the deicing agent, the concentration of the deicing agent, the length of the management section, the width of the road surface, and the thickness of the water film. However, there are many data to be collected, and the parameter adjustment The process is more complicated
