Abstract

The invention discloses a method, device, equipment and medium for determining the temperature of a central drainage ditch of a tunnel. The method includes calculating the first characteristic parameter, the second characteristic parameter and the third characteristic parameter, and combining the starting point water temperature and the length to be measured to obtain the measured The end water temperature of the drainage ditch, when the end water temperature is lower than the temperature critical value, the corresponding supplementary insulation layer thickness is selected according to the difference between the end water temperature and the temperature critical value, and the effective insulation layer is obtained according to the initial insulation layer thickness and the supplementary insulation layer thickness. layer thickness, when the effective insulation thickness is not greater than the insulation thickness threshold, the effective insulation layer thickness is taken as the initial insulation layer thickness, and the steps of obtaining the initial insulation layer thickness, the measured length of the drainage ditch to be measured, and the starting water temperature are repeated. If the thickness is greater than the thermal insulation thickness threshold, an electric heating system start command is sent to turn on the electric heating system to improve the thermal insulation effect of the central drainage ditch.

Description

technical field [0001] The invention relates to the field of tunnels, in particular to a method, device, equipment and medium for determining the temperature of a central drainage ditch in a tunnel. Background technique [0002] In recent years, more and more alpine regions and seasonally frozen regions have begun to plan and build tunnels to improve the convenience of local transportation. However, due to the unique low temperature and water-rich conditions in cold regions and seasonal frozen land regions, the linings of many completed tunnels have problems such as cracking, ice hanging and frost heave, which bring great safety to tunnel operation. hidden danger. As an important part of the tunnel drainage system, the central drainage ditch can effectively reduce the water pressure behind the lining. Therefore, how to determine the water temperature in the central drainage ditch and how to realize the thermal insulation of the central drainage ditch is an important issue t...
