Description

Technical Field

[0001] This invention relates to the field of roadbeds, and more particularly to a concrete roadbed for municipal engineering and its paving method. Background Technology

[0002] The roadbed is the foundation of a railway track or pavement, a geotechnical structure formed through excavation or filling. Its primary function is to provide the necessary conditions for track or pavement laying and train or vehicle operation, and to bear the static and dynamic loads of the tracks, rolling stock, pavement, and traffic, while simultaneously transferring and dispersing these loads deeper into the ground. In longitudinal profile, the roadbed must ensure the required elevation of the line; in horizontal plane, it connects with bridges and tunnels to form a complete and continuous railway line. In civil engineering, the roadbed occupies a significant position in terms of construction volume, land area, and investment.

[0003] For example, patent application number 201811290377.X discloses a roadbed structure and a roadbed construction method, including a substrate; a fill body disposed on the substrate; a first isolation layer disposed at a first preset depth of the fill body; and a second isolation layer disposed at a second preset depth of the fill body. The roadbed construction method is applied to the construction of the aforementioned roadbed structure. The first preset depth is below the maximum freezing depth, and the second preset depth is above the maximum freezing depth. The first isolation layer at the first preset depth prevents lower moisture from migrating towards the frozen area, and the second isolation layer at the second preset depth prevents surface moisture from migrating towards the frozen area. This effectively prevents the impact of moisture migration on the frozen area, prevents the "boiler effect," reduces the incidence of roadbed disasters, and lowers maintenance costs.

[0004] The roadbed and similar roadbed structures do not have heating functions. When the road surface freezes in winter, the ice can only be removed manually or by machine, which is not only time-consuming and laborious, but also affects traffic. Improvements are needed. Summary of the Invention

[0009] Preferably, a second umbrella-shaped cover plate is fixedly sleeved on the upper end of the heat pipe, and a third umbrella-shaped cover plate is provided above the second umbrella-shaped cover plate.

A plurality of heat dissipation holes are opened on the third umbrella-shaped cover plate, and a waterproof and breathable membrane is laid on the top surface of the third umbrella-shaped cover plate.

[0010] Preferably, the cavity is provided with a plurality of lower heat-conducting plates, the bottom surface of the lower heat-conducting plates is fixed with a plurality of heat-conducting sheets, the top surface of the heat-conducting plates is fixedly connected to the bottom end of the heat-conducting rod, and the upper end of the heat-conducting rod passes through the third umbrella-shaped cover plate and the waterproof and breathable membrane and extends above the waterproof and breathable membrane.

[0023] Example 1

[0024] like Figure 1-4 As shown, a concrete roadbed for municipal engineering includes a roadbed body 21. A pipe 2 is horizontally embedded inside the roadbed body 21. Several heating devices are installed inside the pipe 2 along the length of the pipe 2. Several maintenance pipes 4 are fixed at the top of the pipe 2 along the length of the pipe 2. The upper end of the maintenance pipe 4 extends to the road surface. A concrete cover plate 6 is provided on the top of the maintenance pipe 4.

[0025] An electric wire 10 is installed inside the pipe 2 along its length. The heating device includes a heater 3, which is electrically connected to the electric wire 10. A first umbrella-shaped cover plate 7 is installed above the heater 3. The edge of the first umbrella-shaped cover plate 7 is connected to the upper end of an arc-shaped baffle 11 via a hinge 16. The top of the arc-shaped baffle 11 is connected to the first umbrella-shaped cover plate 7 via a spring 15. A heat-conducting pipe 1 is fixedly installed in the center of the first umbrella-shaped cover plate 7. The upper end of the heat-conducting pipe 1 passes through the top of the pipe 2 and extends above the pipe 2. A second umbrella-shaped cover plate 14 is fixedly fitted on the upper end of the heat-conducting pipe 1. A third umbrella-shaped cover plate 19 is installed above the second umbrella-shaped cover plate 14. The edges of the second umbrella-shaped cover plate 14 and the third umbrella-shaped cover plate 19 are fixedly connected to form a cavity 22 between them. Several heat dissipation holes 17 are opened on the third umbrella-shaped cover plate 19. A waterproof and breathable membrane 20 is laid on the top surface of the third umbrella-shaped cover plate 19. Multiple lower heat-conducting plates 18 are installed inside the cavity 22. Several heat-conducting sheets 8 are fixed on the bottom surface of the lower heat-conducting plates 18. The top surface of the heat-conducting plates 18 is fixed to the bottom end of the heat-conducting rod 12. The upper end of the heat-conducting rod 12 passes through the third umbrella-shaped cover plate 19 and the waterproof and breathable membrane 20 and extends above the waterproof and breathable membrane 20. Several upper heat-conducting plates 23 are fixed on the top of the heat-conducting rod 12.

[0026] Working principle: When the road surface is icy, the wire 10 is energized, which causes the heater 3 to start heating. Since the heater 3 is surrounded by the arc-shaped baffle 11, the heat is concentrated in the space enclosed by the arc-shaped baffle 11 and conducted to the cavity 22 through the heat conduction pipe 1. Then, the heat is dissipated through the heat dissipation hole 17 and conducted to the road surface to heat the road surface. At the same time, the heat in the cavity 22 heats the heat conduction plate 8, and then the heat in the cavity 22 is conducted to the road surface through the heat conduction rod 12 and the upper heat conduction plate 23.

[0027] Example 2

[0028] like Figure 1-4 As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the bottom of the concrete cover plate 6 is fixedly connected to the upper end of the connecting rope 5, and the lower end of the connecting rope 5 is fixedly connected to the sleeve 9, with the sleeve 9 fitted onto the wire 10. The concrete cover plate 6 is removed, and the concrete cover plate 6, through the connecting rope 5, carries the wire 10 and the nearby heater 3 out through the inspection pipe 4, allowing for maintenance of the heater 3 near the inspection pipe 4.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
