Background technology
As everyone knows, at Cold Winter, in the time that cement concrete bridge deck freezes because of snowfall, will bring and have a strong impact on traffic safety to bridge is unimpeded, and even cause bridge to close, and make troubles to passenger-cargo communications and transportation, bring massive losses to national economy.
Now widely used bridge deicing method has: 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 environmental protection solve the deicing or snow melting difficult problem of bridge, 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 bridge deck 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 bridge deck deicing or snow melting that the utility model provides, comprise power supply, bridge floor layer and bridge steel structure layer, between described bridge floor layer and bridge steel structure layer, be provided with asphalt concrete layer, overcoat, waterproofing course and leveling layer, described bridge floor layer, asphalt concrete layer, overcoat, waterproofing course, leveling layer and bridge steel structure layer superpose and join successively; Also embedding in described overcoat have a line with heating function, and described line with heating function is connected with described power supply.
In technique scheme, described overcoat is that 2cm concrete C50 adds glue overcoat.
In technique scheme, described in the line with heating function that is embedded in overcoat be carbon fiber heating cable.
In technique scheme, described leveling layer is the thick C50 cement concrete of 8cm leveling layer.
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 overcoat, carbon fiber cable heating after energising, heat is phoresied in overcoat and savings, and then heat is by carbon fiber by light radiation, and overcoat slowly evenly discharges to surrounding by thermal-radiating form, heat conducts in bridge floor layer and heats, thereby reaches the object of deicing or snow melting.
The utility model, for the carbon fiber heating system of concrete bridge deck 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.
Referring to Fig. 1, the utility model, for the carbon fiber heating system of concrete bridge deck deicing or snow melting, comprises power supply (not shown), bridge floor layer 1, bridge steel structure layer 2, asphalt concrete layer 3, overcoat 4, waterproofing course 5, leveling layer 6 and line with heating function 7.
Described bridge floor layer 1, asphalt concrete layer 3, overcoat 4, waterproofing course 5, leveling layer 6 and bridge steel structure layer 2 superpose and join successively, and described overcoat 4 adds glue overcoat for 2cm concrete C50, and described leveling layer 6 is the thick C50 cement concrete of 8cm leveling layer.Also embedding in described overcoat 4 have a line with heating function 7, and described line with heating function 7 is connected with described power supply, and in the present embodiment, described line with heating function 7 is carbon fiber heating cable.
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.
The content not being described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
