Chained multi-layer assembled prefabricated hollow slab heat dissipation roadbed structure and construction method

The invention relates to a chain type multi-layer assembled prefabricated hollow slab heat dissipation roadbed structure and a construction method. An existing frozen soil roadbed disease prevention and treatment technology has the problem that structural rigidity and investment cost cannot be considered at the same time. The structure comprises at least two layers of hollow roadbed plates, wherein each layer of hollow roadbed plate is formed by splicing a plurality of hollow plates in the same plane; the hollow plate is a long-strip-shaped rectangular plate, and ventilation holes are formed in the hollow plate. The hollow subgrade plates comprise longitudinal hollow subgrade plates and transverse hollow subgrade plates, hollow plates in the longitudinal hollow subgrade plates are longitudinally arranged, hollow plates in the transverse hollow subgrade plates are transversely arranged, and the longitudinal hollow subgrade plates and the transverse hollow subgrade plates are vertically arranged at intervals.
