Embodiment 2
[0026] In linear engineering, large-area line surface cooling is required to realize heat flow control in different directions between the environment and the protected object. We can continuously lay this unit device on the roadbed according to requirements (such as image 3 As shown), the shell material is generally selected from plastics with small thermal conductivity and good waterproof performance to make a sealed shell. The water-absorbing material is made of foam glass and diatomaceous earth, and 87% of the volume of the shell is added to the shell,
[0027] The present invention can be realized in the permafrost subgrade engineering by the following two approaches, one, can be as figure 2 The shown shell unit device is buried on the roadbed according to a certain density, such as image 3 In the plane layer shown, dense filling soil is laid on the layer; secondly, it can be built with concrete blocks or hollow bricks, such as Figure 4 The rhombus-shaped skeleton ...
