Abstract
A subway station bearing column heat dissipation system and a heat dissipation method applying loop heat pipes belong to the field of underground space safety. The invention uses the tunnel bearing column as a carrier, uses the tunnel emergent fire as a background, and applies the loop heat pipe and the phase-change material to solve the problem that the bearing column collapses because of the strength reduction caused by the short-time large-scale heating of the emergent fire. The main components comprise a liquid compensator, an evaporator, a liquid pipeline, a condenser coiled pipe, a phase change material layer and an underground municipal water supply network branch. When a fire disaster happens to the tunnel, the phase change material layer covered on the pillar absorbs instant heat; meanwhile, the heat absorbed by the working medium in the evaporator buried in the phase-change material layer is transferred to the condenser in the soil layer, the coiled pipe of the condenser is connected with a municipal pipe network branch, and the heat is taken away by water flow flowing in the pipe network. The system can delay or even avoid collapse of the bearing column of the subway station due to fire during fire, provide precious time for subsequent fire extinguishing and disaster relief work, and reduce property loss and casualties.

Background
In recent years, the traffic industry is rapidly developed, the per-capita automobile conservation quantity is greatly improved, and along with the influence of automobile congestion on life, road traffic is difficult to meet the requirement of people going out. The problems of traffic transportation are greatly relieved due to the underground tunnel and the urban rail transit, and the urban rail transit becomes the first choice for urban resident trip. Therefore, the safety problems of subways and tunnels are also of great importance.
At present, fire is a main factor influencing and threatening the safe operation of a tunnel, and in addition to endeavoring to take fire-fighting measures to avoid the fire, people pay more and more attention to how to extinguish the fire and ensure the safety of the tunnel when the fire occurs. The tunnel heel post is first when making a rush in the conflagration, and the tradition mixes earth post and because of the material problem, is heated and collapses easily and cause the disaster. In 2018, in the event of collapse of Guangzhou subway, when workers work, fire disasters are caused due to short circuit of welding wires, and in the rescue process, the palm surface is unstable, so that collapse is caused, and 3 people die and a large amount of economic loss are caused; for example, in the event of a fire accident in a Cloux tunnel in France, the tank train explodes and fires, so that the tunnel part collapses, and the vehicle can be driven through the refurbished tunnel for 96 days. In this case, if it is ensured that the temperature of the load-bearing column does not rise and the strength does not fall in the event of a fire, there is a chance that the load-bearing column will not collapse, which in turn reduces casualties and economic losses. The prior literature is reviewed to find no solution to the problem of thermal collapse of the load bearing column. The utility model discloses towards the heel post, increased phase change material and loop heat pipe on the basis of the earth post is mixed to the tradition and resisted and eliminate outside heat, improved the survivability of heel post in the conflagration, degraded fire hazard greatly, provide more valuable time for follow-up relief of disaster.
The system operates during sudden fire, on one hand, the phase-change material attached to the outer part of the bearing column absorbs the instantaneous heat of the fire, and the bearing column is prevented from being heated instantaneously, and concrete expands to collapse; on the other hand, a loop heat pipe in the phase-change material receives heat to the evaporator, the working medium in the evaporator is heated and evaporated, the steam enters the condenser along with the pipeline, is liquefied in the condenser and releases heat, and returns to the compensator under the action of capillary force generated by the capillary core in the evaporator; in addition, the snakelike condenser is connected with a city pipe network phase branch, and heat emitted by the condenser is absorbed by water flow in the pipeline and taken away along with the water flow, so that heat of the bearing column accepted by the phase-change material is absorbed and emitted circularly, and the phase-change material is ensured to be recycled.
