Abstract

The invention relates to the technical field of road construction, in particular to an aerogel low-temperature anti-freezing viaduct that comprises a box-type beam bridge floor and a supporting body for supporting the box-type beam bridge floor; aerogel heat preservation layers wrap the left side, the right side and an outer surface of the lower portion of the box-type beam bridge floor; heating cables are evenly laid on the upper surface of a hollow position of the box-type beam bridge floor, and an aerogel suspended ceiling is arranged below the heating cables. The problem that in the priorart, the low-temperature heat preservation capacity of the viaduct is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an airgel low-temperature antifreeze viaduct. Background technique [0002] With the continuous development of the city, in order to alleviate the traffic pressure, there are more and more viaducts. Because the viaduct is in an overhead state, there is no geothermal heat underneath, and the air circulation is fast, and the low-temperature insulation capacity is poor. It is very easy to freeze in cold weather, and it is difficult to melt snow, which brings great hidden dangers to driving safety. [0003] In order to solve the problem of driving safety of viaducts under low-temperature climate conditions, Chinese patent CN105926436A discloses an elevated pavement structure that is safe to drive under low-temperature conditions. By laying heating cables in the concrete waterproof layer at the bottom of the road surface, the road surface of the viaduct is heated to melt ice...
