Description
Technical field
It is special the present invention relates to subgrade engineering field, more particularly to the field of prevention and treatment seasonal frozen soil region roadbed frost damage disease
It is not that one kind can use solar energy supplement depth geothermal energy, guarantees that geothermal energy can be stablized to the maximum heat supply freezing deep layer and conveying
Device.
Background technique
Frozen soil refer to zero degrees celsius hereinafter, and various rocks and soil containing ice, the frozen soil area in China is vast, accounts for
The 53.5% of national territorial area, wherein about 75% traffic route is located at frost zone and in short-term permafrost region.Since frozen soil has
Rheological characteristic, long-term strength are far below instantaneous strength feature, and which results in build engineering structure in permafrost region must just face
Two is big dangerous: frost heave and thaw collapse, this property of frozen soil have seriously affected the traffic safety of railway, have substantially increased railroad maintenance
Cost hinders seasonal frost region economic development construction.Therefore, roadbed frost damage disease is effectively solved to anticipate with important society and economy
Justice.
Soil property, moisture, temperature are the three elements of roadbed frost damage, and fully controlling any one factor just can avoid roadbed
The generation of frost failure, control measure is concentrated mainly in soil property and moisture at present, such as is changed and filled out coarse-grained soil, setting discharge outlet,
But the result of actual measurement shows that above-mentioned measure still can not fundamentally solve roadbed frost damage disease.
In temperature control, it is mainly limited to passive protection, insulation board roadbed is such as laid with, fills thermal insulation berm, but due to the winter
Ji Luji relative atmospheric is in the condition of high temperature, and roadbed still can constantly distribute heat into atmosphere, and then can be due to heat waste is excessive
Cool down frost heave.
Though favorably using earth source heat pump at present, actively freeze deep layer to roadbed and convey heat, adjusts roadbed heat budget balance, keep away
Exempt from the device of roadbed cooling frost heave, but in actual use, endotherm section is because quickly absorbing surrounding geothermal energy, the ground on neighbouring stratum
Thermal energy recharge rate is insufficient, endotherm section can be made to form subzero temperature area, and then frost heave may occur for endotherm section, influence the smooth journey of roadbed
Degree, and such device can not play good working effect in the insufficient area of geothermal energy, have compared with big limitation.And China's season
Freeze area and be predominantly located at high latitude area, the solar energy in these areas is very sufficient.
Therefore, the geographical distribution situation based on China's geothermal energy and solar energy, can be using solar energy addedly using one kind
The separate type temperature regulating device of thermal energy, to solve the problems, such as that the roadbed frost damage disease of China seasonal frost region has broad application prospects.
Summary of the invention
The technical problem to be solved by the present invention is to only lean on single geothermal energy for current seasonal frost region roadbed frost damage control measures
Or the problem that single solar energy is ineffective, providing one kind can use solar energy compensation geothermal energy, and geothermal energy is stablized
It is delivered to roadbed maximum and freezes deep layer, to realize the one of prevention and treatment roadbed frost damage disease under the premise of guaranteeing that geothermal energy abundance is stablized
The monomer separation formula heating tube of kind seasonal frost region roadbed frost damage prevention and control.
