Six, temperature-sensing probe is set: hard sleeve is set between the heating cable laid, and hard sleeve is fixed, again temperature-sensing probe is located in hard sleeve, and the external temperature controller (10) of temperature-sensing probe and road is electrically connected, then away from the one end at body edge, road, shutoff is carried out to hard sleeve;
Seven, paving fills out bed course, and spreading the thickness filled out is 2-5cm;
Eight, road surface pavement layer.
Heat insulation layer: in order to block heat transmission, reduces the techonosphere of unavailable heat loss; Damp-proof course: for preventing the techonosphere of moisture through ground of building lot or soil.
The heat conduction that the application adopts heating cable to produce is to supercrust, and arranging heat road surface conduction upward as much as possible by heat insulation layer, improve heating efficiency.
The conduction depending heat self radiation and bed course alone there will be slow or heat radiation inequality of dispelling the heat, the problems such as temperature-sensing probe data are inaccurate, the application adopts the heat dissipating layer be pressed against on heating cable layer to be scattered as quickly as possible by heat, guarantee pavement temperature is even, reduces the temperature error of temperature-sensing probe.
As preferably, described reflecting layer is be glued at the aluminium foil layer on described heat insulation layer.
As preferably, described heat dissipating layer is metal net layer, crimping or connected by conductor between adjacent metal stratum reticulare.
Metal net layer as heat dissipating layer, thus makes sub-surface to penetrate on insulating layer, and wraps wire lath and heating cable thus can play the effect of better fixing metal net and heating cable, guarantees that heat radiation evenly.Also can reduce road surface because of the setting of interlayer simultaneously and cause the risk of staggered floor, improve the steadiness on road surface.
As preferably, described wire lath is connected with grounding wire.
As preferably, described temperature-sensing probe leaves even temperature gap between described cable cable.
The setting of even temperature gap is guaranteed can not closely get close between temperature-sensing probe and heating cable, thus the data that the heat that the data of guarantee gained are heating cable generations obtains after heating layer evenly scatters, for temperature control provides reliable reference, guarantee that the temperature on road surface is in control range as much as possible, reduce unnecessary energy consumption, raise the efficiency.
Collect by temperature controller the temperature data that temperature-sensing probe gathers constantly, road pavement temperature is analyzed, reach that temperature controller specifies open the temperature of heating cable time, namely temperature controller sends the energising of instruction heating cable and starts heating.
As preferably, described bed course is the cement bed course of backfill.
As preferably, described cement bed course is cement mortar or pea gravel concrete.
As preferably, after step 7 completes, detect whole heat-generating system in 24-48 hour and before road surface pavement layer, problem points is repaired.
As preferably, described connector is staple.
As preferably, described heating cable layer comprises and uniform is multiplely arranged in the hot zone that described reflecting layer is formed by least one heating cable.
As preferably, described heating cable is roundabout to be back and forth arranged on described reflecting layer, and the outer side edges of described heating cable layer near sub-surface limit is 8-12cm to the distance on described sub-surface limit.
The thickness of bed course, when 2-5cm, can ensure that the heat of heating cable is fully utilized, and ensures again that bed course can protect heating cable layer well simultaneously.Heating cable layer back gauge sub-surface limit 8-12cm, whole road surface is heated evenly, and ensures again sub-surface simultaneously and has enough wide joint face between cement bed course and supercrust, ensureing the intensity of road body.
For guaranteeing that heating is effectively carried out in practice, can on sub-surface uniform multiple hot zone, each hot zone arranges one group of heat-generating system, often the circuit organized between heat-generating system is independent circuits, in parallel between independent circuits, wherein one group breaks down because of unpredictable situation, can not have influence on the duty of other system.
The heating cable of the application adopts filament carbon fibre cable, have very high safety, heating-up temperature also can not be too high, and too high temperature body performance of satisfying the need equally impacts, what can extend road body by the design of the application road body makes the life-span, improves the safety on road surface.
In sum, the present invention has following beneficial effect:
1, the application extensively can apply to winter temperature lower ground district, may be used on speedway or common road solving speedway, common road is icy on road causes running car generation traffic accident problem; Also may be used on outdoor public place to solve concrete structure road surface (square) and freeze and cause pedestrian's safety hidden danger to ask to carry; For some manufacturing enterprises, the structure of the application solution plant area temperature in outdoor winter also can be used to cross low concrete cargo handling platform and to freeze, cause factory's handling operation security hidden trouble.
2, the application's structure is simple, intelligence degree is high, energy consumption is low, long service life.
3, the application thoroughly solves problem icy on road, and namely road pavement heats before icy on road, ensures the performance turn improving road body while road surface can not freeze, and prevents road surface from freezing affect road body performance, shortening road body application life.
