Description
Technical field
The present invention relates to tunnel surrounding field, especially a kind of energy tunnel recombination formula ground temperature energy freeze-proof heating system, fit
The tunnel-liner for educating area for underground water agensis and owing can be extracted with inverted arch bottom country rock ground temperature behind, and to tunnel
Road surface and lining cutting are heated.
Background technology
In recent years, as China's transport development is fast-developing, the quantity of tunnel in cold area grows with each passing day, but in tunnel in cold area
Freeze injury problem becomes increasingly conspicuous, part newly built tunnels come into operation after soon, just there occurs freeze injury on a large scale, had a strong impact on tunnel
Traffic safety.Investigation discovery is carried out to the highway in cold region tunnel that has runed, in tunnel in cold area, has more than 80% all to there is freeze injury now
As wherein about 60% occurs the slight freeze injury phenomenon such as percolating water, and about 24% lining concrete peeling, cracking, slump, depression occurs
Deng serious cold damage problem.Tunnel in cold area can not chronically solve the frost heave of tunnel in cold area using conventional heater by service at present
With the disease problem such as freeze, and have the shortcomings that energy consumption is big, operation cost is high and show using the active heating measure of electrical heating method
Shape, is badly in need of the novel anti-freezing heating system of exploitation energy-conserving and environment-protective.
