Problems solved by technology
[0002] The airport runway is an important facility of the airport. In the cold winter season and special weather conditions, the surface of the runway is prone to frost or ice, which seriously affects the safety of aircraft takeoff and landing. Therefore, flight delays are often directly caused by weather reasons.
At present, the method of melting ice at airports is to use chemical methods to spray snow melting agents, or to use snow removal equipment to clean after snow. No matter which method is used, it is implemented after frost or ice is formed, which has caused damage to the normal operation of the airport. In addition, the existing deicing and defrosting costs are extremely high, and it is labor-intensive and time-consuming

Embodiment Construction
[0011] Such as figure 1 As shown, on the cement concrete base 1 lay a steel pipe 2 connected to the heating device in circulation, on the steel pipe 2 lay a load-bearing heat-conducting layer made of a steel plate 3, and finally lay cement concrete on the steel plate 3 surface layer4.
[0012] Such as figure 2 As shown, on the cement concrete base 1' lay a steel pipe 2' connected to the heating device, on the steel pipe 2' lay a load-bearing heat-conducting layer made of a mesh steel material layer 3', and finally in A cement concrete surface layer 4' is laid on the mesh rigid material layer 3'.
[0013] The invention can control the heating temperature and the flow rate of the heating device to achieve the best use effect.

The invention discloses a deicing system for an airfield runway, which relates to the technical field of construction of airfield runways. A rigid pipeline circularly connected with a heat supply device is paved between a cement concrete substrate and a cement concrete surface layer; and a load bearing heat conducting layer is paved between the rigid pipeline and the cement concrete surface layer. When possible frosting or icing of the airfield runway caused by rain or ice or frost is predicted, the heat supply device can be started and hot air or water is supplied to the rigid pipeline, so that higher temperature of the cement concrete substrate is achieved, moisture on the surface of the cement concrete substrate is heated and volatilized, and defrosting or icing phenomenon can be avoided. By adopting the deicing system, the rigid pipeline can be protected from the weight pressure of a plane. Moreover, heat in the rigid pipeline can be uniformly distributed through the load bearing heat conducting layer, so that the surface temperature of the cement concrete substrate above and in a certain range around the entire paved load bearing heat conducting layer is raised and the paving density of the rigid pipeline can be lowered.
