HOLLOW CONTROL LAYER OF CHANNEL TYPE FOR COOLING OF SLOPE OF ROADBED FROM FROZEN SOIL Russian patent published in 2020 - IPC E01C3/06 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to mechanics of frozen soils for cooling slope of roadbed from frozen soil. Hollow control layer of the channel type for cooling of the slope of the roadbed from frozen soil, in which the hollow control layer of the channel type is laid on the slope of the roadbed with both its ends located near the upper and lower edge of the slope of the roadbed. Hollow control layer of the channel type has the first ventilation hole near the upper edge of the slope and the second ventilation hole near the lower edge of the slope. First ventilation opening communicates with second ventilation opening to form tunnel for bidirectional air transfer from upper to lower edge of slope and / or from lower to upper edge of slope, to accelerate convective heat transfer of air in hollow control layer of channel type for cooling slope of roadbed. Channel-type hollow control layer comprises several hollow tubes arranged parallel to each other in single- or multilayer structure.

EFFECT: technical result consists in improvement of efficiency of convective heat transfer for slope of roadbed in different conditions, including both positive wind field and reverse wind field.
