Description

Technical Field

[0001] The present invention relates to the technical field of bridge deck paving structures, and particularly to a directional heat-conducting bridge deck paving structure. Background Art

[0002] Bridge deck paving refers to the protective layer paved on the bridge deck to prevent the wheel from directly wearing the bridge deck, disperse the wheel load, and provide a flat and anti-slip driving surface for vehicles. Its structure is diverse, and the common ones are asphalt concrete paving layers and cement concrete paving layers. The asphalt concrete paving layer is mostly used for urban expressways, main road bridges, etc., and is composed of upper fine-grained and lower medium-grained asphalt concrete, with characteristics such as anti-slip, wear-resistant, and load-bearing. The cement concrete paving layer has high strength, strong wear resistance, and good stability, but more joints may affect driving comfort. The selection and construction quality of the bridge deck paving structure are crucial for the durability, driving safety, and comfort of the bridge.

[0003] The patent document with Chinese publication number CN105803884B discloses a thin-layer steel bridge deck paving structure. The bridge deck paving structure is a layered composite structure, and the layered composite structure from bottom to top is successively an anti-corrosion layer, a waterproof layer, a buffer layer, and a paving layer. The paving layer includes an upper paving layer and a thin-layer wear-resistant layer, and the wear-resistant layer is composed of thermoplastic rosin and bauxite clinker. This bridge deck paving structure has the advantages of light weight, high strength, excellent flexibility, good non-deformation of the steel plate, fatigue resistance, and durability.

[0004] In the bridge deck paving structure in the above patent document, when the temperature is relatively low on rainy and snowy days in winter, ice is likely to appear on the surface of the bridge deck paving structure. At present, the main methods for deicing the bridge deck include mechanical methods and chemical melting methods. Although the mechanical deicing method can effectively remove the ice layer on the bridge deck to a certain extent, it has obvious hysteresis and is difficult to respond to sudden ice conditions in a timely manner. The chemical melting method, especially the use of deicing salts, can quickly melt ice and snow, but it is easy to cause environmental pollution and corrosion to the bridge structure. Therefore, a directional heat-conducting bridge deck paving structure is proposed. Summary of the Invention

[0005] In view of the above problems, a directional heat-conducting bridge deck paving structure is provided. While the transmission shaft rotates, it drives the propeller to rotate, so that the propeller drives the heat exchange liquid inside the U-shaped tube to flow. At the same time, the heated heat exchange liquid inside the liquid storage tube enters the U-shaped tube, causing the temperature of the U-shaped tube to rise. The hardening layer is heated through the U-shaped tube, thereby melting the ice and snow on the bridge deck paving structure. The problem that the surface of the bridge deck paving structure is prone to icing in winter is solved.

[0006] To solve the problems of the existing technology, the present invention provides a directionally heat-conducting bridge deck pavement structure, which includes a bridge main body, a bridge deck pavement layer provided on the upper end surface of the bridge main body, a U-shaped pipe provided inside the bridge deck pavement layer for conducting heat, and a liquid storage pipe provided on one side of the bridge main body and capable of being connected to the input end of the U-shaped pipe. The bridge deck pavement layer includes a hardening layer; the U-shaped pipe is cast inside the hardening layer;

[0007] Inside the input end of the U-shaped pipe, a rotatable transmission shaft is horizontally arranged, and a driven gear is fixed at one end of the transmission shaft;

[0008] At the end of the U-shaped pipe away from the driven gear, a plurality of propellers for driving the heat exchange liquid to flow are equidistantly installed;

[0009] On the outer wall of the liquid storage pipe near the top, a number of heat conversion plates capable of converting sunlight into heat are longitudinally and equidistantly arranged. The heat conversion plates can heat the exchange liquid inside the liquid storage pipe;

[0010] At the center of the inside of the liquid storage pipe, a rotatable shaft that can rotate unidirectionally is longitudinally arranged, and a driving gear that can mesh with the driven gear is fixed at the bottom end of the rotatable shaft;

[0011] The output end of the U-shaped pipe is fixed with a return pipe, and the top end of the return pipe can be fixedly connected to the input end of the liquid storage pipe near the top.

[0012] As a technical solution of the present invention, on both sides of the top of the U-shaped pipe, a number of heat exchange rods are equidistantly fixed. The heat exchange rods are used to transfer the heat inside the U-shaped pipe to the inside of the hardening layer.

[0013] As a technical solution of the present invention, an installation frame is installed inside the input end of the U-shaped pipe, and the transmission shaft is rotatably installed at the center of the installation frame.

[0014] As a technical solution of the present invention, a sealing cover for sealing is installed at the top end of the liquid storage pipe, and a one-way bearing is installed at the center of the sealing cover.

[0015] As a technical solution of the present invention, the rotatable shaft is installed inside the one-way bearing; a windmill that can rotate with the air flow is fixed at the top end of the rotatable shaft.

[0016] As a technical solution of the present invention, the bridge deck pavement layer further includes an anti-corrosion layer laid on the upper end surface of the bridge main body, and a first bonding layer for increasing the connection strength between the hardening layer and the anti-corrosion layer is laid on the upper end surface of the anti-corrosion layer.

[0017] As a technical solution of the present invention, an elastic buffer layer with certain resilience and elongation characteristics is laid on the upper end surface of the hardening layer. A waterproof layer is laid on the upper end surface of the elastic buffer layer, and a drainage groove for guiding accumulated water to flow to both sides is opened on the upper end surface of the waterproof layer.

[0018] As a technical solution of the present invention, a second bonding layer is laid on the upper end surface of the waterproof layer.

[0019] As a technical solution of the present invention, a paving base layer for protecting its surface is laid on the upper end surface of the second bonding layer.

[0020] As a technical solution of the present invention, an anti-skid wear layer for bearing wheel loads is laid on the upper end surface of the paving base layer.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. In this application, multiple heat conversion plates arranged outside the liquid storage pipe convert sunlight into heat energy, so that the heat energy of the heat conversion plates is conducted to the liquid storage pipe, and then the liquid storage pipe heats the heat exchange liquid inside it. Then, while the transmission shaft rotates, it drives the propeller to rotate, so that the propeller drives the heat exchange liquid inside the U-shaped pipe to flow. At the same time, the heated heat exchange liquid inside the liquid storage pipe enters the U-shaped pipe, causing the temperature of the U-shaped pipe to rise. The hardening layer is heated through the U-shaped pipe, solving the problem that the surface of the bridge deck paving structure is prone to icing in winter.

[0023] 2. In this application, a return pipe is fixedly connected to the output end of the U-shaped pipe, and the output end of the return pipe is connected to the input end at the top of the liquid storage pipe, so that the cooled heat exchange liquid inside the U-shaped pipe can flow back into the liquid storage pipe through the return pipe for reheating. The heat exchange liquid is recycled, thus saving the usage cost.

[0024] 3. This application utilizes the air flow to drive the windmill to rotate around the central axis of the rotating shaft. When the windmill rotates, it can drive the rotating shaft to rotate synchronously. At the same time, the rotating shaft drives the driving gear to rotate synchronously. Then, while the driving gear rotates, it drives the transmission shaft to rotate through the driven gear meshing with it, thereby providing kinetic energy for the rotation of the propeller. The directional heat-conducting bridge deck paving structure is more environmentally friendly and energy-saving. Description of the Drawings

Detailed implementation mode

[0036] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation modes.

[0037] See Figure 1 - Figure 10 As shown in

[0038] The directionally heat-conducting bridge deck pavement structure includes a bridge main body 1, a bridge deck pavement layer 2 provided on the upper end surface of the bridge main body 1, a U-shaped tube 3 provided inside the bridge deck pavement layer 2 for conducting heat, and a liquid storage tube 4 provided on one side of the bridge main body 1 and capable of connecting to the input end of the U-shaped tube 3. The bridge deck pavement layer 2 includes a hardened layer 22; the U-shaped tube 3 is cast inside the hardened layer 22;

[0039] A rotatable transmission shaft 33 is horizontally arranged inside the input end of the U-shaped tube 3, and a driven gear 35 is fixed to one end of the transmission shaft 33;

[0040] A plurality of heat conversion plates 41 capable of converting sunlight into heat are longitudinally and equidistantly arranged on the outer wall of the liquid storage pipe 4 near the top. The heat conversion plates 41 can heat the exchange liquid inside the liquid storage pipe 4.

[0041] A rotatable shaft 51 that can rotate unidirectionally is longitudinally arranged at the center inside the liquid storage pipe 4. A driving gear 52 that can mesh with the driven gear 35 is fixed to the bottom end of the rotatable shaft 51.

[0042] The output end of the U-shaped pipe 3 is fixed with a return pipe 6, and the top end of the return pipe 6 can be fixedly connected to the input end of the liquid storage pipe 4 near the top.

[0043] The sunlight is converted into heat energy through a plurality of heat conversion plates 41 arranged outside the liquid storage pipe 4, so that the heat energy of the heat conversion plates 41 is conducted to the liquid storage pipe 4. Then, the liquid storage pipe 4 heats the heat exchange liquid inside it. Then, by using the rotation of the rotatable shaft 51, the driving gear 52 rotates synchronously while the rotatable shaft 51 rotates, and the driven gear 35 meshes with the driving gear 52 to drive the transmission shaft 33 to rotate. When the transmission shaft 33 rotates, the propeller 34 rotates synchronously. The rotation of the propeller 34 drives the heat exchange liquid inside the U-shaped pipe 3 to flow. When the heat exchange liquid inside the U-shaped pipe 3 flows, the heated heat exchange liquid inside the liquid storage pipe 4 enters the U-shaped pipe 3. At this time, the heat of the heated heat exchange liquid is first transferred to the surface of the U-shaped pipe 3, and then the U-shaped pipe 3 transfers the heat to the inside of the hardening layer 22. At this time, the temperature of the hardening layer 22 rises accordingly. Thus, the bridge deck paving layer 2 can melt the ice and snow on its surface. Effectively avoid the phenomenon of icing on the bridge deck. At the same time, while the heat exchange liquid flowing through the U-shaped pipe 3 continues to flow, the temperature of the heat exchange liquid inside the U-shaped pipe 3 gradually decreases, and then the heat exchange liquid enters the inside of the return pipe 6 from the output end of the U-shaped pipe 3. Finally, the cooled heat exchange liquid inside the U-shaped pipe 3 returns to the liquid storage pipe 4 through the return pipe 6 for circulation.

[0044] See Figure 4 、 Figure 5 and Figure 6 As shown, a plurality of heat exchange rods 31 are equidistantly fixed on both sides of the top of the U-shaped pipe 3. The heat exchange rods 31 are used to transfer the heat inside the U-shaped pipe 3 to the inside of the hardening layer 22.

[0045] To improve the heat diffusion efficiency of the U-shaped pipe 3, a plurality of heat exchange rods 31 are horizontally fixed on both sides of the top of the U-shaped pipe 3, so that the heat on the U-shaped pipe 3 diffuses to both sides through the heat exchange rods 31, thereby increasing the heat dissipation area of the U-shaped pipe 3.

[0046] See Figure 7 As shown, an installation frame 32 is installed inside the input end of the U-shaped pipe 3. The transmission shaft 33 is rotatably installed at the center of the installation frame 32.

[0047] To ensure the stability of the transmission shaft 33, the mounting bracket 32 is fixed inside the input end of the U-shaped tube 3, and then the transmission shaft 33 is inserted into the center of the mounting bracket 32, so that the transmission shaft 33 can rotate around the central axis of the mounting bracket 32, effectively ensuring the stability of the transmission shaft 33 and preventing the transmission shaft 33 from displacing horizontally during rotation.

[0048] See Figure 4 、 Figure 6 、 Figure 7 and Figure 8 As shown in

[0049] To prevent the heat exchange liquid inside the liquid storage tube 4 from leaking, the sealing cover 45 is fixed to the top of the liquid storage tube 4, so that the sealing cover 45 can seal the top of the liquid storage tube 4. Effectively prevent the heat exchange liquid inside the liquid storage tube 4 from evaporating due to heat.

[0050] See Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown in

[0051] To ensure that the rotating shaft 51 can rotate in a fixed direction, a one-way bearing 451 is installed at the center of the sealing cover 45, and then the rotating shaft 51 is sealed and installed inside the one-way bearing 451, so that the rotating shaft 51 can only rotate in a fixed direction. Prevent the reverse rotation of the rotating shaft 51 from causing the flow of the exchange liquid inside the liquid storage tube 4 to be blocked. To enable the rotating shaft 51 to rotate, a windmill 53 is fixed to the top of the rotating shaft 51. When the air flows, it can push the windmill 53 to rotate around the central axis of the rotating shaft 51. When the windmill 53 rotates, it can drive the rotating shaft 51 to rotate synchronously, making the directional heat-conducting bridge deck paving structure more environmentally friendly and energy-saving.

[0052] See Figure 2 and Figure 4 As shown in

[0053] In order to protect the surface of the bridge main body 1, an anti-corrosion layer 21 is laid on the upper end surface of the bridge main body 1. The anti-corrosion layer 21 is made of fiber-reinforced composite material. By virtue of the good corrosion resistance of the anti-corrosion layer 21 and its good ability to co-deform with steel, the anti-corrosion layer 21 can well protect the bridge main body 1. The anti-corrosion ability of the bridge main body 1 is effectively improved, thereby enhancing the durability and safety of the bridge main body 1. To improve the connection stability between the anti-corrosion layer 21 and the hardening layer 22, a first bonding layer 211 with a thickness of 2 cm is laid on the upper end surface of the anti-corrosion layer 21, so that the first bonding layer 211 can enhance the bonding force between the anti-corrosion layer 21 and the lower end surface of the hardening layer 22, effectively preventing the hardening layer 22 from detaching from the anti-corrosion layer 21 under the action of vehicle loads and the natural environment. Thus, the connection stability between the anti-corrosion layer 21 and the hardening layer 22 is improved.

[0054] See Figure 2 and Figure 4 As shown, an elastic buffer layer 23 with certain resilience and elongation characteristics is laid on the upper end surface of the hardening layer 22. A waterproof layer 24 for blocking water seepage is laid on the upper end surface of the elastic buffer layer 23. Drainage grooves 241 for guiding accumulated water to flow to both sides are provided on the upper end surface of the waterproof layer 24.

[0055] By laying an elastic buffer layer 23 with a thickness of 4 cm to 6 cm on the upper end surface of the hardening layer 22, and the main material of the elastic buffer layer 23 being rubber asphalt sand glue, by virtue of the characteristics of high resilience, large elongation rate, and high strength of the elastic buffer layer 23, it can effectively absorb and disperse the impact of vehicle loads on the bridge deck, reducing the stress and deformation of the paving layer. When a heavy vehicle travels on the upper end surface of the bridge paving layer 2, in order to avoid water seepage in the bridge paving layer 2, a waterproof layer 24 with a thickness of 3 cm is laid on the end surface of the elastic buffer layer 23. When water permeates through the anti-skid wearing layer 27, the paving base layer 26, and the second bonding layer 25, the water is blocked by the waterproof layer 24 and stops further penetration. At the same time, the already penetrated water will enter the interior of the drainage grooves 241 preset on the upper end surface of the waterproof layer 24, and finally the water flows out through the drainage grooves 241. This avoids the accumulation of water inside the bridge paving layer 2, preventing the bridge paving layer 2 from being damaged due to long-term water immersion. The service life of the bridge paving layer 2 is effectively extended.

[0056] See Figure 2 and Figure 4 As shown, a second bonding layer 25 is laid on the upper end surface of the waterproof layer 24, and a paving base layer 26 is laid on the upper end surface of the second bonding layer 25.

[0057] To improve the connection stability between the waterproof layer 24 and the paving base layer 26, a second bonding layer 25 with a thickness of 2 cm to 3 cm is laid on the upper end surface of the waterproof layer 24, so that the second bonding layer 25 can enhance the bonding force between the waterproof layer 24 and the lower end surface of the paving base layer 26, effectively preventing the waterproof layer 24 from separating from the paving base layer 26. Thus, the connection stability between the waterproof layer 24 and the paving base layer 26 is improved.

[0058] See Figure 2 and Figure 4 As shown, the paving base layer 26 is made of asphalt high-modulus mixture.

[0059] Utilizing the good thermal stability, durability and good anti-fatigue performance of the paving base layer 26, it can not only correct the unevenness of the bridge deck structure, thereby improving the flatness and driving comfort of the entire bridge deck paving. It can also effectively improve the anti-permanent deformation ability of the entire bridge deck paving structure, reduce the occurrence of diseases such as ruts. During the process of the bridge deck paving structure repeatedly bearing vehicle driving, the paving base layer 26 can maintain the integrity of the bridge deck paving structure, resist the repeated impact and vibration of vehicles, and avoid fatigue damage of the road. It solves the deformation diseases such as ruts caused by insufficient pavement strength and poor high-temperature performance of the anti-skid wear layer 27.

[0060] See Figure 2 and Figure 4 As shown, an anti-skid wear layer 27 is laid on the upper end surface of the paving base layer 26.

[0061] Utilizing the anti-skid, wear-resistant and wheel load dispersing properties of the anti-skid wear layer 27, it ensures that vehicles can effectively prevent skidding and losing control when the anti-skid wear layer 27 is in rainy days or on slippery roads. It improves the driving stability and safety of vehicles in rainy days. The anti-skid wear layer 27 is made of materials such as asphalt concrete or colored resin with excellent wear-resistant performance, so that the anti-skid wear layer 27 can offset the wear between the vehicle tires and the anti-skid wear layer 27 during driving, thereby extending the service life of the bridge deck paving structure. At the same time, the flat anti-skid wear layer 27 can also provide a smooth driving surface for vehicles, reduce bumps and vibrations, and improve the comfort of driving and riding.

[0062] Working principle of the present invention: Through a plurality of heat conversion plates 41 arranged outside the liquid storage pipe 4, the heat conversion plates 41 can effectively convert sunlight into heat energy, and the heat conversion plates 41 conduct this heat energy to the liquid storage pipe 4. The liquid storage pipe 4 then heats the heat exchange liquid inside it. Then, while using the air flow, it pushes the windmill 53 to rotate around the central axis of the rotating shaft 51. When the windmill 53 rotates, it can drive the synchronous rotation of the rotating shaft 51. When the rotating shaft 51 rotates, it drives the synchronous rotation of the driving gear 52. At this time, the driving gear 52 drives the transmission shaft 33 to rotate through the driven gear 35 meshed with it. The rotation of the transmission shaft 33 drives the rotation of the propeller 34 at the same time. When the propeller 34 rotates, it promotes the flow of the heat exchange liquid inside the U-shaped pipe 3. During the flow of the heat exchange liquid inside the U-shaped pipe 3, the heated heat exchange liquid inside the liquid storage pipe 4 is introduced into the U-shaped pipe 3. The heated heat exchange liquid first transfers the heat to the surface of the U-shaped pipe 3, and then the U-shaped pipe 3 further transfers the heat to the inside of the hardened layer 22, resulting in an increase in the temperature of the hardened layer 22. This temperature change enables the bridge deck paving layer 2 to effectively melt the ice and snow on its surface. At the same time, during the continuous flow of the heat exchange liquid flowing through the U-shaped pipe 3, the temperature of the heat exchange liquid gradually decreases. The heat exchange liquid then enters the return pipe 6 from the output end of the U-shaped pipe 3 and finally returns to the inside of the liquid storage pipe 4 through the return pipe 6 to complete the entire cycle process.

[0063] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
