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
The present invention relates to field, tunnel, particularly relate to a kind of tunnel in cold area heat production captation.
Background technology
When tunnel is built in cold district, engineering circles often worries that frost heave can bring all harm to tunnel.Frost heave refers to that water-bearing media moisture freezes the phenomenon of volume expansion.Be divided into microcosmic frost heave and carefully see frost heave: microcosmic frost heave refers to that moisture infiltrates the frost heaving of lining concrete inside and generation under the effect of larger pressure or under the effect of capillary pressure.Multigelation, year in and year out, lining concrete intensity reduces.If do not adopt remedial measures or improper measures, liner structure just by local failure, finally can develop into overall collapse.
Thin sight frost heave refers to that underground water freezes and the frost heaving of generation on the leakage passage of lining cutting.Just freeze in these holes to percolating water in winter, frost-heave force can destroy fragile cement structure, makes cement structure between aggregate loose, affects the bulk strength of liner structure.
In the country rock in tunnel, in the sprayed mortar of preliminary bracing, in the gap of preliminary bracing and secondary lining and lining concrete, all possible moisture, in cold season when moisture spot temperature is lower than 0 DEG C, the frost heaving of moisture all can occur.In addition, in cold district, sprayed mortar and lining concrete can produce damage deterioration under Frozen-thawed cycled effect, have an impact to the durability of its structure, and serious meeting causes tunnel structure to be scrapped and serious accident occurs during runing.
Especially percolating water position freeze-thaw damage is more obvious, but at present for this kind of problem mostly adopt be add insulation layer, the measures such as design portal are to tunnel insulation, and high cost, produces effects low.
