Background technology
As everyone knows, at Cold Winter, in the time that cement concrete pavement freezes because of snowfall, to bring and have a strong impact on to road or the unimpeded and traffic safety of bridge, even cause road and bridge and socked-in, make troubles to passenger-cargo communications and transportation, bring massive losses to national economy.
Now widely used road or bridge deicing method have: manually remove method, mechanical removal method, chemical thaw ice etc., the drawbacks such as that these methods all exist is time-consuming, effort or not environmental protection.How can be effective, laborsaving, save time and the deicing or snow melting difficult problem of environmental protection ground solving road, this is the problem that the utility model will be studied.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, and a kind of carbon fiber heating system for concrete road deicing or snow melting is provided, and makes it have simple in structure, environmental protection and energy saving, the feature that safe and reliable, structure is light and handy.
A kind of carbon fiber heating system for concrete road deicing or snow melting that the utility model provides, comprise power supply, earth's surface, intermediate layer and roadbed, described earth's surface, intermediate layer and roadbed superpose and join successively, described intermediate layer is layer of concrete, described layer of concrete contains reinforcing bar and wire gauze, and described wire gauze is connected with reinforcing bar by welding; Also embedding in described layer of concrete have a line with heating function, and line with heating function is connected with described wire gauze, and one end of line with heating function is connected with described power supply.
In technique scheme, described line with heating function is embedded in the layer of concrete apart from earth's surface 68~72mm.
In technique scheme, described line with heating function is embedded in the layer of concrete apart from earth's surface 70mm.
In technique scheme, described line with heating function is carbon fiber heating cable.
In technique scheme, described wire gauze is that diameter is 6mm weld metal silk screen.
Heating system described in the utility model, it is carbon fiber far infrared heating system, its operating principle is: will be connected with power supply and be embedded in the carbon fiber heating cable in concrete or cement mortar, carbon fiber cable heating after energising, heat is phoresied in concrete or cement mortar and savings, and then heat is by carbon fiber by light radiation, and concrete slowly evenly discharges to surrounding by thermal-radiating form, heat conducts in earth's surface and heats, thereby reaches the object of deicing or snow melting.
The utility model, for the carbon fiber heating system of concrete road deicing or snow melting, has following beneficial effect:
(1) simple in structure: easy to use, without occupation of land, without equipment room;
(2) environmental protection and energy saving: no waste discharge, electric conversion rate is up to 98.2%, the 5 seconds heat generating wire cable surface temperatures of switching on reach 65 ℃, than metal electric heating material energy-saving 30% left and right, than air-conditioning and other mode of heating energy-conservation nearly 1/3rd, and by the acting of Based Intelligent Control and batch (-type), make the usage charges can be lower;
(3) safe and reliable: the stable performance of carbon fiber own, again through multilayer protection and shielding, the not starting the arc of power-off, there will not be electric leakage, mistake electrical phenomena, forms and has eliminated Electrostatic Hidden Troubles overall time with structure;
(4) service life identical with structure, later maintenance is simple, can be benefited for a long time;
(5) compared with other mode of heating, without indirect use cost, unmanned expenses of labour of later stage and plant maintenance expense;
(6) Heat stability is good, can be not sometimes hot and sometimes cold, inactivity decay, be so far the most efficiently, the most energy-conservation one is for hot product, heat stores in concrete, is difficult for scattering and disappearing;
(7) system architecture is not produced to any impact;
(8) lightweight: can effectively to alleviate construction weight, thereby improve the technical performance of member, the tensile strength of reinforcement table body.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Embodiment 1
Referring to Fig. 1, the utility model, for the carbon fiber heating system of concrete road deicing or snow melting, comprises power supply (not shown), earth's surface 1, roadbed 2, is intermediate layer, reinforcing bar 4, wire gauze 5 and the line with heating function 6 of layer of concrete 3.
Described earth's surface 1, layer of concrete 3 and roadbed 2 superpose and join successively, described layer of concrete 3 contains reinforcing bar 4 and wire gauze 5, described wire gauze 5 is connected with reinforcing bar 4 by welding, in the present embodiment, described wire gauze 5 for diameter be 6mm weld metal silk screen.Also embedding in described layer of concrete 3 have a line with heating function 6, described line with heating function 6 is 68mm with the distance on earth's surface 1, and line with heating function 6 is connected with described wire gauze 5, and one end of line with heating function 6 is connected with described power supply, in the present embodiment, described line with heating function 6 is carbon fiber heating cable.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, and its difference is: described line with heating function 6 is 70mm with the distance on earth's surface 1.
Embodiment 3
The present embodiment is substantially the same manner as Example 1, and its difference is: described line with heating function 6 is 72mm with the distance on earth's surface 1.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
