Problems solved by technology

The deep-buried drainage pipe is to bury the drainage pipe below the freezing line to prevent the water in the drainage pipe from freezing and blocking the drainage channel, and the groundwater cannot be discharged in time, which will cause the water pressure after the lining to increase, and frost heaving will threaten the lining structure. Its burial depth requires detailed temperature field investigation according to local conditions to prevent failure of insufficient depth or waste of investment caused by too deep burial

Abstract

The invention discloses a cold region tunnel thermal insulation system and an installation method thereof. According to the thermal insulation system, heat (cold) wind is continuously injected into anarch insulation device which is fixed on the inner wall of the tunnel, the characteristics of good thermal insulation performance and poor thermal conductivity of air are used, and the single thermalinsulation time of the system can be prolonged when the energy consumption of thermal insulation is reduced. The cold region tunnel thermal insulation system can prevent tunnels in permafrost regionsfrom freezing thawing, and can also prevent tunnels in seasonal cold regions from frost heaving, so that the tunnels are kept from frozen damage. The cold region tunnel thermal insulation system hashigh reliability, modular parts facilitate installation and maintenance, and the cold region tunnel thermal insulation system can be used not only for a newly built tunnel, but also for the thermal insulation reconstruction of an existing tunnel.

Description

Technical field [0001] The invention relates to the field of tunnels in cold regions, in particular to an insulation system and installation method for tunnels in cold regions. Background technique [0002] 44% of China's districts belong to cold areas, and the tunnels built in these areas are cold area tunnels. The biggest problem faced by tunnels in cold regions is tunnel frost damage. In recent years, my country’s investment in cold-region tunnel frost damage treatment has continued to increase. Even so, many tunnels are still suffering from frost damage and even abandoned. Cold-region tunnels are becoming tunnels. Important research topics in the world. The main reasons for freezing damage of tunnels in cold regions are freeze-thaw and frost heave: Freeze-thaw refers to a phenomenon in which the self-supporting capacity of the surrounding rock decreases due to the ablation of the frozen surrounding rock due to the increase in temperature in the tunnel, which changes the stres...
