Problems solved by technology

[0003] The current bridge deck pavement structure is easy to form an ice layer on the surface under the conditions of rainy and snowy weather and a sudden drop in temperature in winter, which leads to a significant reduction in its anti-skid ability, causing skidding of vehicles or pedestrians, and reducing the safety of the road. Safety performance is also prone to vicious traffic accidents, and in severe cases, it will endanger the safety of life and property

Embodiment 1

[0029] Such as figure 1 As shown, the present invention provides an active anti-ice and snow bridge deck asphalt pavement structure, comprising an asphalt composite layer 9, a carbon fiber composite layer 10 and a concrete layer 11 laid sequentially on the bridge deck foundation structure from top to bottom, and also includes Multiple sets of anti-condensation components uniformly arranged for anti-ice and snow.

[0030] Such as figure 2 and image 3 As shown, the structure of the anti-condensation assembly specifically includes an external air compressor 1, which is used to inhale and compress external air into the first booster device 2, and the first booster device 2 The inlet end communicates with the outlet of the air compressor 1, and is used to increase the compressed air pressure, and the increased air pressure is 2-2.5 atmospheres.

[0031] A horizontally arranged main metal pipe 6 is buried in the concrete layer 11, and the main metal pipe 6 is vertically arrange...

Embodiment 2

[0045] Furthermore, in order to further increase the compressed air pressure and make the formed air film structure more stable, a plurality of second booster devices 3 for pressurization are also arranged on the branch metal pipe 7, and the second booster The pressure device 3 is arranged between two adjacent first connecting pipes, so that a plurality of air film structure surfaces are connected in sequence to form the entire protective surface.

Embodiment 3

[0047] Further, in order to enhance the air flow rate and improve the working efficiency, a Laval tube 5 for increasing the air flow rate is arranged on the first connecting pipe.

[0048] The Laval tube 5 can maximize the air velocity and make the air film structure more stable.

[0049] Compared with the prior art, the present invention provides an active anti-ice and snow bridge deck asphalt pavement structure, which can remove ice and snow on roads and bridges in time, greatly reduce the occurrence of traffic accidents, ensure driving safety, and have good practicability , especially suitable for areas with ice and snow on roads in winter, it is worth popularizing.

Abstract

The invention belongs to the technical field of road bridge engineering, and relates to bridge deck asphalt pavement structure capable of actively resisting ice and snow. The structure comprises an asphalt composite layer, a carbon fiber composite layer and a concrete layer which are sequentially arranged from top to bottom, and further comprises a plurality of sets of anti-condensation assemblies which are evenly distributed. Each anti-condensation assembly comprises an air compressor; a first supercharging device in which the inlet end is communicated with the outlet of the air compressor; a main metal pipe which is buried in the concrete layer, wherein the middle section of the main metal pipe is communicated with the outlet end of the first supercharging device; at least one branch metal pipe which is embedded in the concrete layer, wherein one end of the branch metal pipe is communicated with the main metal pipe; multiple nozzles which are arranged above the branch metal pipes and embedded in the asphalt composite layer, wherein the upper surfaces of the nozzles are flush with the upper surface of the asphalt composite layer, and the nozzles communicate with the branch metal pipes through first connecting pipes; and a heating device which is arranged on the main metal pipe and heats the air flowing through the main metal pipe. Ice and snow can be removed in time, traffic accidents are reduced, and driving safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of road and bridge engineering, in particular to a bridge deck asphalt pavement structure that actively resists ice and snow. Background technique [0002] Bridge deck pavement refers to the protective layer paved on the bridge deck with asphalt concrete, cement concrete, high molecular polymer and other materials in order to protect the bridge deck and distribute the concentrated load of the wheels. [0003] The current bridge deck pavement structure is very easy to form an ice layer on the surface under the conditions of rainy and snowy weather and a sudden drop in temperature in winter, which leads to a significant reduction in its anti-skid ability, causing skidding of vehicles or pedestrians, and reducing the safety of the road. Safety performance is also prone to vicious traffic accidents, and in serious cases, it will also endanger the safety of life and property. Contents of the invention [0004]...
