Description

Technical Field

[0001] The invention relates to a pavement structure. Background Art

[0002] It is difficult for vehicles to drive on roads in poor conditions, such as when the road is soft and prone to dents. For example, there is seasonal frozen soil on roads in some parts of my country. Under such road conditions, the frozen soil will expand when the temperature is low in winter, and will melt and shrink when the temperature is high in summer, forming local cavities, making the soil muddy, the foundation easy to sink, become bumpy, and prone to foundation settlement. In order to prevent the melting of the frozen soil roadbed in summer, phase change materials are used to adjust the temperature inside the roadbed in some sections in different seasons, that is, hot rods are used. Although the hot rod is a natural refrigerator and does not require power, the production cost of the hot rod for the entire highway is very high. At the same time, if the temperature changes drastically between summer and winter, the liquid ammonia inside the hot rod may be completely vaporized. At this time, the foundation is very likely to melt, resulting in a road condition where vehicles cannot pass. Summary of the invention

[0048] The honeycomb connection unit 6 is provided with a first tensile layer 4, specifically, the first honeycomb subunit 61, the second honeycomb subunit 62, the third honeycomb subunit 63 and the first tensile layer 4 are combined with each other along the axial direction of the honeycomb hole to form the honeycomb connection unit 6. In this embodiment, Figure 5 As shown, the first honeycomb subunit 61, the third honeycomb subunit 63 and the second honeycomb subunit 62 are sequentially arranged from top to bottom along the axial direction of the honeycomb hole, and the first anti-tension layer 4 is arranged between the first honeycomb subunit 61 and the third honeycomb subunit 63, between the third honeycomb subunit 63 and the second honeycomb subunit 62, and on the upper surface of the first honeycomb subunit 61 and the lower surface of the second honeycomb subunit 62, so as to form a honeycomb connection unit 6. The first anti-tension layer 4 is connected to each honeycomb subunit 61, 62, 63 by bonding.

[0049] like Figure 1 As shown, this embodiment also includes a connecting mechanism, which is used to connect any two honeycomb connection units 6. The connecting mechanism includes an edge sealing profile, which is arranged at the end of the honeycomb connection unit 6. The edge sealing profile includes a first edge sealing profile 7 and a second edge sealing profile 8 that can cooperate with each other. The first edge sealing profile 7 and the second edge sealing profile 8 are respectively connected to different honeycomb sub-units 61, 62, and 63.

[0050] In the present embodiment, the edge-sealing profile is arranged at the end of the third honeycomb subunit 63, and a plurality of edge-sealing profiles can be arranged according to the honeycomb height of the third honeycomb subunit 63. The shapes of the ends of the first edge-sealing profile 7 and the second edge-sealing profile 8 are matched, and the connection methods include bonding or connection by locking. The first tensile layer 4 on the honeycomb subunit can be extended in advance so that the first tensile layer 4 extends to the surface of the corresponding edge-sealing profile. A honeycomb connecting block 9 is arranged on the first tensile layer 4 of the two edge-sealing profiles connected to each other, so that a honeycomb connecting block 9 is arranged above and below the edge-sealing profile to which the two edge-sealing profiles are connected. The honeycomb connecting block 9 is a honeycomb structure. The honeycomb connecting block 9 in the present embodiment has a honeycomb pore density greater than 150kg / m 3 High-density honeycomb structure, for example, the honeycomb hole density is 160kg / m 3 , 180kg / m 3 , 200kg / m 3 , 250kg / m 3 , 280kg / m 3 or 300kg / m 3 The honeycomb holes of the honeycomb connection block 9 are axially consistent with the honeycomb holes of the honeycomb subunits 61, 62, and 63. A second tensile layer 10 is provided on the upper surface and / or lower surface of the honeycomb connection block 9, and the setting method is bonding. A bolt connector 11 is provided in the honeycomb connection block 9, and the bolt connector 11 is used to connect the two honeycomb connection blocks 9 above and below the edge sealing profile.

[0051] The material of the first tensile layer 4 and / or the second tensile layer 10 is fiber-reinforced resin. Fiber-reinforced resin is a composite material of fiber and resin. Fiber includes one or more of glass fiber, basalt fiber, aramid fiber, ceramic fiber, bamboo fiber, cloth, carbon fiber, metal fiber, boron fiber, asbestos fiber, Orlon fiber, polyester fiber, nylon fiber, vinylon fiber, polypropylene fiber, polyimide fiber, cotton fiber and sisal. Resin includes one or more of vinyl resin, epoxy resin, phenolic resin, polyurethane resin, benzoxazine resin, polyimide resin, bismaleimide resin, urea-formaldehyde resin, melamine resin, unsaturated polyester resin, silicone resin and polyurethane.

[0052] like Figure 1 and Figure 5 As shown, when in use, the first honeycomb subunit 61, the third honeycomb subunit 63, the second honeycomb subunit 62 and the first tensile layer 4 are bonded to each other to form a plurality of honeycomb connection units 6, and the first honeycomb subunit 61, the third honeycomb subunit 63 and the second honeycomb subunit 62 are as shown in FIG. Figure 1 and Figure 5As shown, they are arranged sequentially from top to bottom. The ends of two adjacent third honeycomb subunits 63 are respectively provided with a first edge-sealing profile 7 and a second edge-sealing profile 8, that is, one of the first edge-sealing profile 7 and the second edge-sealing profile 8 is provided at the end of one third honeycomb subunit 63, and the other is provided at the end of another third honeycomb subunit 63. The first edge-sealing profile 7 and the second edge-sealing profile 8 are connected by a lock connection and / or bonding, so that the two honeycomb connection units 6 are connected. The first tensile layer 4 provided on the upper and lower surfaces of the third honeycomb subunit 63 is pre-extended so that the first tensile layer 4 extends to the upper and lower surfaces of the first edge-sealing profile 7 or the second edge-sealing profile 8. A honeycomb connection block 9 is provided on the first tensile layer 4 above the first edge-sealing profile 7 and the second edge-sealing profile 8, and a honeycomb connection block 9 is provided under the first tensile layer 4 below the first edge-sealing profile 7 and the second edge-sealing profile 8, and the upper and lower honeycomb connection blocks 9 are tightened by bolt connectors 11. In order to further increase the splicing strength of adjacent honeycomb connection units 6, a second tensile layer 10 is provided on the upper surface of the honeycomb connection block 9 located above, and a second tensile layer 10 is provided on the lower surface of the honeycomb connection block 9 located below. In this way, after the adhesive glue is cured, all the spliced ​​honeycomb connection units 6 are integrated and subjected to force as a whole. Then, a protective body 12 is laid on the above-mentioned completed structure.

[0053] The protective body 12 can also be pre-set, that is, the protective body 12 is set on the first tensile layer 4 above the first honeycomb subunit 61. When connecting, if there is a gap between the protective bodies 12 corresponding to the two honeycomb connecting units 6, such as Figure 6 As shown, the gap, that is, Figure 6 As shown, an asphalt protective body or a quartz sand resin layer 5 is filled on the second tensile layer 10 located on the top.

[0054] like Figure 1 As shown, this embodiment takes the connection of two cellular connection units 6 as an example. The cellular connection unit 6 is generally a rectangular parallelepiped. When multiple cellular connection units 6 are connected, the connection mechanism is arranged on the left and right sides of the cellular connection unit 6 and Figure 1 The front and back sides of the paper make the entire structure extend in all directions along the radial direction of the honeycomb holes.

[0055] Alternatively, the end of the third honeycomb subunit 63 is bonded to the edge sealing profile, and the two edge sealing profiles are connected by locking and / or bonding, so that the two third honeycomb subunits 63 are connected, and then the first honeycomb subunit 61 and the second honeycomb subunit 62, the first tensile layer 4, the honeycomb connecting block 9, the second tensile layer 10, the protective body 12 and other structures are arranged to finally form a force-bearing integral structure.

[0056] The honeycomb holes of the honeycomb subunits 61, 62, 63 and / or the honeycomb connecting blocks 9 are filled with foam material. The foam material can be selected from foam materials with heat preservation performance according to actual conditions. In this embodiment, polyurethane foam, polyphenyl foam or phenolic foam is selected.

[0057] like Figure 7 As shown, a geotextile-wrapped sand layer 13 is arranged below the honeycomb structure. The geotextile-wrapped sand layer 13 is a geotextile containing sand inside. When in use, the honeycomb structure and the geotextile-wrapped sand layer 13 are directly laid on a swamp or soft soil layer, without laying a riprap roadbed and a fill layer, to build a permanent road or a temporary road.

[0058] like Figure 8 As shown, a sand layer 14 can be provided as required below the geotextile-wrapped sand layer 13. When paving, the soft soil on the road surface can be leveled first, and then the sand layer 14 and the geotextile-wrapped sand layer 13 are laid, so that the traditional road foundation structure can be omitted.

[0059] Example 2

[0060] like Fig. 9 As shown, this embodiment includes a filling layer 16, and the filling layer 16 is arranged below the honeycomb structure. Another embodiment is, as Fig.10 As shown, the honeycomb structure, the geotextile-wrapped sand layer 13 and the fill layer 16 are arranged in sequence from top to bottom.

[0061] Some frozen soil roads may have wading phenomena in some seasons. In this case, a riprap layer 15 can be used. The riprap layer 15 provides heat preservation and ventilation functions. The riprap layer 15 is a riprap roadbed or a crushed stone roadbed. For example, Fig.11 As shown, the honeycomb structure, the geotextile sand layer 13, the fill layer 16 and the riprap layer 15 are arranged in sequence from top to bottom. Fig.12 As shown, the honeycomb structure, the soil filling layer 16 and the riprap layer 15 are arranged in sequence from top to bottom.

[0062] Example 3

[0063] like Fig.13 As shown, an elevated structure 17 is arranged below the honeycomb structure, and the elevated structure 17 includes columns. This is suitable for situations where frozen soil roads involve animal migration, ensuring the passage of animals, people or water.

[0064] Example 4

[0065] like Fig.14As shown, this embodiment is a simplified embodiment, and this embodiment includes a layer of honeycomb structure, namely, a first high-density honeycomb layer 1. The first high-density honeycomb layer 1 is formed by connecting a plurality of first honeycomb subunits 61, and the connection method includes connection by a connecting mechanism and bonding. A first tensile layer 4 is respectively provided on the upper surface and the lower surface of the first high-density honeycomb layer 1. A protective body 12 is provided above the first tensile layer 4 on the upper surface of the first high-density honeycomb layer 1. Similar to embodiments 1, 2, and 3, the lower part of the honeycomb structure can be provided as required. In this embodiment, a geotextile-wrapped sand layer 13 and a sand layer 14 are provided below the first high-density honeycomb layer 1.

[0066] Example 5

[0067] like Fig.15 As shown, this embodiment is a simplified embodiment, and this embodiment includes a two-layer honeycomb structure, namely a first high-density honeycomb layer 1 and a second high-density honeycomb layer 2, and the first high-density honeycomb layer 1 and the second high-density honeycomb layer 2 are bonded up and down. The first high-density honeycomb layer 1 is formed by connecting a plurality of first honeycomb subunits 61, and the second high-density honeycomb layer 2 is formed by connecting a plurality of second honeycomb subunits 62, and the connection method includes connection by a connecting mechanism and bonding. The first tensile layer 4 is respectively arranged on the upper surface of the first high-density honeycomb layer 1, between the first high-density honeycomb layer 1 and the second high-density honeycomb layer 2, and on the lower surface of the second high-density honeycomb layer 2. A protective body 12 is arranged above the first tensile layer 4 on the upper surface of the first high-density honeycomb layer 1. As in embodiments 1, 2, and 3, the lower part of the honeycomb structure can be arranged as required. In this embodiment, a geotextile sand layer 13 and a sand layer 14 are arranged below the second high-density honeycomb layer 2.

[0068] The present invention provides a honeycomb structure that can be used to disperse the load of automobile tires, dispersing the load of automobile tires from a stress point of the honeycomb structure to the entire honeycomb structure. In the multi-layer honeycomb structure, the first high-density honeycomb layer 1 directly bears the load of automobiles, forklifts or other heavy wheeled equipment, and the second high-density honeycomb layer 2 contacts the road below, such as stone loads, so the honeycomb density and strength of the two layers are set to be relatively large and can withstand a certain load; since the load has been dispersed when it reaches the middle layer medium-density honeycomb layer 3, from the perspective of cost saving, the medium-density honeycomb layer 3 is set to be smaller; the first tensile layer 4 and the second tensile layer 10 are used for force connection.

[0069] The present invention can effectively distribute the concentrated load of up to about 8 tons of a single tire of a vehicle that repeatedly passes on the road surface to the road surface below the present invention. The present invention can be applied to frozen soil roads. In the case of frozen soil roads, even if the frozen soil melts on a large scale or has potholes, the maximum contact pressure between the present invention and the frozen soil base is still less than 1.4 tons per square meter; under this uniform load state, even if the melted frozen soil is very soft, it can still be in an elastic deformation state, so the road surface using the present invention will not collapse as a whole, and when the vehicle tire load leaves, the slight deformation of the road surface can be completely restored. The honeycombs of the honeycomb subunits and / or honeycomb connecting blocks 9 are filled with foam material to increase the thermal insulation performance of the honeycomb material, which is more conducive to preventing the melting of frozen soil in summer in the case of frozen soil roads. The present invention can also be used for swamps or soft sections, urban municipal roads and highways.

[0070] The embodiments of the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutes that can be thought of by those skilled in the art are all within the protection scope of the present invention.
