Description
Technical field
The invention belongs to road field, and in particular to a kind of to prevent antifreeze road surface icy on road in cold weather.
Background technology
Existing conventional pavement snow melting de-icing method is mainly including manually or mechanically removing method, spreading Snow Agent method etc., snow melt
Deicing effect is all undesirable, and snow melt can only be again carried out in the case where there is ice and snow road, it is impossible in ice and snow product on road surface
Before prevented.The existing Snow Agent for most commonly using can also damage existing Pavement Performance, and Snow-melting speed is slow, intelligence degree
The problems such as low, efficiency is low, energy consumption is big.
The content of the invention
The purpose of the present invention is directed to above mentioned problem, and to provide a kind of intelligence degree high, can thoroughly solve road surface freezing, prevents
The only antifreeze road surface of road surface freezing.
Above-mentioned technical purpose of the invention technical scheme is that：
A kind of antifreeze road surface, including it is laid on the protection against the tide on sub-surface that is levelling and cleaning out successively from the bottom to top
Floor, prevent heat from down conducting the heat insulation layer of loss, heating cable floor, bed course and road fixed and that protect heating cable floor
Surface layer, the heating cable layer includes that uniform multiple is arranged in the hair formed on the heat insulation layer by least one heating cable
Hot-zone, to leave between adjacent hot zone and be provided with temperature-sensing probe between reinforcement fixed interval (FI), the heating cable of each hot zone, described
Even temperature gap is left between temperature-sensing probe and heating cable, is additionally provided with for that will send out between the heating cable layer and heat insulation layer
The even heat that electric heating cable layer sends spreads apart the heat dissipating layer for coming.
Heat insulation layer：It is used to stop heat transfer, reduces the techonosphere of invalid thermal losses；Damp-proof layer：For preventing building ground
Techonosphere of the moisture of base or soil through ground.
The application is conducted to supercrust using the heat that heating cable is produced, and heat to the greatest extent may be used by setting by heat insulation layer
Can ground road surface conduction upward, raising heating efficiency.
The setting of even temperature gap ensures closely be got close between temperature-sensing probe and heating cable, so as to ensure the number of gained
According to being the data that are obtained after heating layer uniformly scatters of heat that heating cable is produced, reliably referred to for temperature control is provided, it is ensured that
