Problems solved by technology

In addition, in cold regions, shotcrete and lining concrete will be damaged and deteriorated under the action of freeze-thaw cycles, which will affect the durability of the structure, and seriously lead to the scrapping of the tunnel structure and major safety accidents during operation
[0005] Especially the freezing and thawing damage is more obvious at the leaking water location. However, most of the current solutions to this kind of problems are adding insulation layers, designing portals and other measures to keep the tunnel insulated. The cost is too high and the effect is low.

Abstract

The invention discloses a cold region tunnel heat production and water collection device which comprises a water collection member and a heat production and water collection member, wherein the water collection member guides and collects water seepage of a tunnel lining; a part of water collected by the water collection member is drained by a tunnel drainage pipe; the other part of water collected by the water collection member flows into the heat production and water collection member and reacts with quicklime contained in the heat production and water collection member to generate heat; and the heat is transferred to the interior of the tunnel lining through the water collection member for heating a tunnel. In winter, a stationary member guides the water seepage of the tunnel into the water collection member and a heat production member, and by employing the principle that quicklime reacts with water to generate a large amount of heat, local heating and heat preservation of the tunnel are carried out; in summer, only the stationary member and the water collection member are mounted, and the water seepage in the tunnel is drained. With the adoption of the measures, the problem of frost heaving due to the fact that ground water freezes on a leakage passage of the lining can be solved effectively; a use method is simple; and the cold region tunnel heat production and water collection device is low in cost, and is economical, safe and practical.

Description

technical field [0001] The invention relates to the field of tunnels, in particular to a heat-generating and water-collecting device for tunnels in cold regions. Background technique [0002] When building tunnels in cold regions, engineering circles often worry about various hazards that frost heave will bring to tunnels. Frost heave refers to the expansion of the volume of water in an aqueous medium when it freezes. Divided into microscopic frost heave and mesoscopic frost heave: microscopic frost heave refers to the phenomenon of frost heave that occurs when water infiltrates into the lining concrete under the action of relatively large pressure or capillary pressure. Repeated freezing and thawing will reduce the strength of lining concrete over time. If remedial measures are not taken or improper measures are taken, the lining structure will start from local damage and eventually develop into overall instability. [0003] Mesoscopic frost heave refers to the phenomeno...
