Heat preservation equipment for tunnel in cold region

Abstract

The invention provides cold region tunnel heat preservation equipment. The equipment comprises a solar power supply device, a first temperature sensor, a heating device, a second temperature sensor, a heat preservation layer structure and a control device, wherein the solar power supply device is provided with a base body, a first support, a solar panel, an energy storage power supply module, a pitching driving structure and a light sensor, the pitching driving structure is used for adjusting a pitching angle of the first support, the first temperature sensor is arranged on the solar power supply device and used for sensing the environment temperature outside the tunnel; the heating device is attached to an inner surface of the tunnel; the second temperature sensor is used for sensing the temperature of an inner surface of the tunnel; and the heat preservation layer structure covers the inner surface of the tunnel. According to the cold region tunnel heat preservation equipment, intelligent control over heating can be achieved according to changes of the internal and external environment temperatures of the tunnel, and lining damage caused by freezing injury is avoided; in addition, a pitching angle of the solar panel can be adjusted according to the change angle and range of solar rays, and solar energy is efficiently utilized.

Description

technical field [0001] The invention belongs to the technical field of tunnel antifreeze, and in particular relates to thermal insulation equipment for tunnels in cold regions. Background technique [0002] The construction of tunnels can reduce the driving distance of vehicles and the cost of road construction, shorten the cost of roads and railways, the tunnel is closer to the straight-line distance between the two places, and can also play a role similar to that of bridges on water, that is, reducing travel time and increasing passenger traffic . [0003] As my country's railway network and highway network extend to high-altitude and other cold regions with harsh climates, the number of tunnels planned to be built in alpine regions has gradually increased. The side wall of the tunnel is made of lining. Freezing damage is common in tunnels in alpine regions. The main cause of freezing damage is that the surrounding rock of the tunnel is a three-phase porous medium compose...

AI Technical Summary

Problems solved by technology

The side wall of the tunnel is made of lining. Freezing damage is common in tunnels in alpine regions. The main cause of freezing damage is that the surrounding rock of the tunnel is a three-phase porous medium composed of solid, liquid and gas. Affected, many cracks will appear inside the surrounding rock, forming water passages. In a low temperature environment, the volume of water freezes will increase, which will generate additional frost heaving force on the tunnel lining structure, destroy the tunnel lining structure, and then cause traffic safety hazards.
