The invention provides a cold region tunnel temperature field indoor experiment system which comprises a main controller and a tunnel model. The tunnel model is arranged in a freezing chamber. The main controller is outside the freezing chamber. The outer boundary temperature control belt of the tunnel model is provided with an electric heater. A surrounding rock temperature sensor is distributed in a surrounding rock. The lower part of a tunnel body is provided with a drainage ditch with the distribution of a water temperature sensor and a water flow sensor. The freezing chamber is also internally provided with a heat insulation water tank, a variable frequency air blower, an air conditioner fan and a room temperature sensor. The heat insulation water tank communicates with the drainage ditch via a water supply pump and a water supply pipe. The variable frequency air blower is at the opening of the tunnel model and faces the tunnel model. The surrounding rock temperature sensor, the water temperature sensor, the water flow sensor, the room temperature sensor, the variable frequency air blower, the air conditioner fan, the electric heater, the water heater and the power supply pump are connected to the main controller. The simulation test of the three-dimensional temperature field of outer air temperature, underground water temperature and surrounding rock temperature of a cold region tunnel is simulated.
Description
technical field [0001] The invention relates to the field of tunnels, in particular to an indoor experiment system for the temperature field of tunnels in cold regions. Background technique [0002] my country's cold regions are widely distributed, and the demand for transportation is strong. As an effective way to cross mountains and ridges, tunnel engineering is widely used. In winter, due to the negative temperature environment, tunnel frost damage occurs from time to time. On the one hand, it manifests as icing problems such as icicles, icicles, and ice plugs. question. How to effectively and scientifically study the temperature field of tunnels in cold regions is very important. [0003] At present, the related temperature field indoor simulation technology can simulate the tunnel structure and thermal insulation structure, but it is not effective in controlling the temperature boundary in a complex environment under the influence of multiple factors, and cannot effec...
