Embodiment Construction
[0008] Prefabricated cement boards (1) are spliced together to make the road surface, and the inside thereof is a cylindrical hollow (2), which communicates with each other, and communicates with an underground drainage pipe (4) by using a pipe (3). There is a gasket at the joint to prevent air leakage. In summer, after the road surface is heated by the sun, the air in the hollow (2) expands, enters the drainage pipe (4), exchanges heat with the cold air in the interior, and then returns to cool down the road surface, preventing the wheels from blowing out due to overheating. In winter, underground heat enters the hollow (2) of the road surface through the pipes to heat up the road surface and melt snow on the road surface.

The invention discloses a temperature-adjusted concrete pavement, which consists of precast hollow floor slabs in split joint. The hollow floor slabs are communicated with urban underground drainage pipelines through pipes. The temperature of the pavement is adjusted by using the temperature difference between the ground and shallow subsurface soil.
Description
technical field [0001] The invention is a temperature-adjustable prefabricated concrete pavement. Background technique [0002] The current concrete pavement is poured at the construction site, and the construction is easily affected by the weather. After pouring, there will be a period of health preservation before it can be opened to traffic, which delays time. Contents of the invention [0003] The invention provides a new road surface, which can shorten the construction period and can also adjust the temperature of the road surface. [0004] The technical scheme adopted in the present invention is: use prefabricated hollow cement board as road surface, and its hollow is cylindrical. The cement boards are spliced with each other, the hollow is connected and communicated with the underground drainage pipe through the pipe, and there is a gasket at the splice to prevent air leakage. Because there is a certain temperature difference between the shallow soil and the gr...
