Description
Technical field
The present invention relates to tunnel surrounding field, the especially a kind of buried ground temperature energy freeze-proof heating system of energy tunnel layer, fit
The tunnel-liner for educating area for underground water agensis and owing can be extracted behind with inverted arch bottom country rock ground temperature, 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, freeze injury is just there occurs on a large scale, had a strong impact on tunnel
Traffic safety.Highway in cold region tunnel to having runed carries out investigation discovery, has more than 80% all to there is freeze injury in tunnel in cold area and shows
As wherein about 60% occurs the slight freeze injury phenomenon such as percolating water, about 24% lining concrete peeling, cracking, slump, depression occurs
Deng serious cold damage problem.At present tunnel in cold area can not chronically solve the frost heave of tunnel in cold area using conventional heater by service
With the disease problem such as freeze, and have the shortcomings that energy consumption is big, operation cost is high using the active heating measure of electrical heating method and show
Shape, is badly in need of the novel anti-freezing heating system of exploitation energy-conserving and environment-protective.
The soil moisture in earth superficial layer hundreds of meters is in increasing trend with depth, and depth often increases by 100 meter temperature rises
High about 3-5 DEG C, the ground temperature at 1000 meters of underground is about 40-50 DEG C, stores huge in the mountain tunnel country rock of buried depth hundreds of meters
Ground temperature energy.The ground temperature in tunnel surrounding can be utilized to be heated to the tunnel-liner positioned at hole end and road surface, can
Tunnel in cold area freeze injury is solved, tunnel in cold area heat supply " self-sufficient " is realized in also energy-conserving and environment-protective.
Ground temperature in the country rock of tunnel-liner behind can be directly collecting in tunnel surrounding by way of GEOTHERMAL WATER
To extract, it is also possible in tunnel double-lining and just bury heat-exchange tube between lining, by the heat transfer cycle medium in pipe and country rock it
Between the temperature difference extract tunnel surrounding ground temperature energy.But GEOTHERMAL WATER collection technique is only applicable to the area of rich groundwater, in underground water
Little or without underground water the area of amount then cannot apply.Huge ground temperature energy is also stores in the country rock of inverted arch bottom, due to residing position
The difference put, the ground temperature in the country rock of inverted arch bottom can then be difficult to be obtained by collecting GEOTHERMAL WATER, can be by inverted arch
