Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and more specifically to a road paving module and a modular road surface using the same. Background Technology

[0002] Currently, highway pavement structures are typically paved with asphalt concrete. In cold winter regions, the shrinkage of asphalt materials due to low temperatures can easily cause pavement cracking. In hot summer regions, the asphalt materials soften due to heat, reducing pavement strength and making the surface prone to unevenness under frequent vehicle traffic.

[0003] Asphalt concrete pavements experience frequent winter-summer transitions, causing the asphalt to lose its adhesive properties and the material particles to loosen, resulting in pavement damage. Repairing this damage is necessary, and the conventional method is to temporarily seal the damaged area, remove the damaged pavement, and repave with asphalt concrete. This method not only affects normal traffic flow but also results in a repaired pavement that cannot achieve the same smoothness as the original pavement, creating seams at the junction of the old and new asphalt concrete, and increasing the cost of pavement operation and maintenance.

[0004] Therefore, how to provide a modular construction method for road surface construction and reduce road maintenance costs is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a road paving module and a modular road surface using the same. The road surface structure is assembled by the modules in a prefabricated manner, which increases the efficiency of road construction, makes the construction process more environmentally friendly, effectively reduces the generation of construction waste, and shortens the construction cycle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A road paving module includes a square block and an assembly block;

[0008] The square block has a first surface and a second surface arranged opposite to each other, and an assembly groove is formed in the middle of the first surface; four corresponding assembly blocks are integrally formed at the four corners of the first surface of the square block; the square block has multiple threaded holes in the bottom wall of the groove corresponding to the assembly groove; and anchoring holes are formed in the middle of the multiple assembly blocks.

[0009] The beneficial effects of this utility model are that the square block structure is simple and easy to manufacture. The square blocks can be assembled in layers, making construction simple and more efficient.

[0010] Preferably, the second surface of the square block has a groove corresponding to the circumferential direction of the threaded hole.

[0011] Preferably, the number of threaded holes is the same as the number of assembly blocks.

[0012] Preferably, the assembly slot is circular or square, and the assembly block is fan-shaped or square.

[0013] The square block is embedded with a steel reinforcement frame; the square block is integrally cast and its side walls are fixed with nameplates.

[0014] This utility model also provides a modular pavement for road construction, which uses the pavement module in the above-mentioned technical solution for road construction, and includes a honeycomb metal frame; the square blocks are provided in multiple layers; the first surfaces of the multiple square blocks in the upper and lower layers are arranged opposite each other; and the assembly block of the same square block in the lower layer is correspondingly embedded in the assembly groove of the adjacent square block in the upper layer; the two layers of square blocks are connected by locking members; a groove for bonding lane lines is reserved on the second surface of the square block in the upper layer; the honeycomb metal frame is laid on the subgrade layer, and concrete is poured into the honeycomb holes of the honeycomb metal frame; a screw is embedded in the concrete, and the screw passes through the threaded hole on the lower square block to fasten the honeycomb metal frame to the lower square block.

[0015] The beneficial effects of the above technical solution are that the road surface thickness is ensured by two layers of square blocks, which are interlocked by assembly blocks and assembly slots and locked by locking components, effectively ensuring the stability of the road surface; a honeycomb metal frame is set on the top surface of the subgrade layer, and concrete is poured into the honeycomb holes of the honeycomb metal frame as the road base layer, which effectively ensures the stability and strength of the road base layer; the concrete is connected to the lower square blocks by pre-embedded bolts, so that the base layer and the road structure layer form an integral and stable structure.

[0016] Preferably, the four assembly blocks corresponding to the four square blocks in the lower layer are all embedded in the assembly slot of one of the square blocks in the upper layer. This ensures the interlocking effect between the upper and lower square blocks and guarantees the quality of road construction.

[0017] Preferably, the combined shape of the four assembly blocks is adapted to the shape of the assembly slot.

[0018] Preferably, the locking element is a bolt, the threaded end of which is screwed into the threaded hole of the upper square block and anchored in the anchoring hole of the lower square block. The bolt enhances the strength of the connection between the upper and lower square blocks.

[0019] Preferably, the upper square block has multiple drainage grooves on its sidewall away from the assembly slot; the length direction of the drainage grooves is parallel to the driving direction. The drainage grooves not only facilitate road drainage, but also provide anti-skid functionality for the vehicle due to their parallel length direction to the driving direction.

[0020] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a road paving module and a modular road using the same. The road construction is carried out by interlocking between the square blocks set in the upper and lower layers. The prefabricated construction method is adopted, which eliminates environmental pollution and construction waste, improves construction efficiency, shortens the construction period, and reduces the maintenance cost of the road.

[0021] The road surface features grooves aligned with the direction of travel, which helps to prevent water accumulation on the road surface and water mist generated by the tires during rainy weather, thus preventing vehicle skidding and ensuring driving safety. At the same time, it reduces the contact area between the tires and the road surface, lowers tire noise, and extends tire life. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] This utility model embodiment discloses a road paving module, including a square block 1 and an assembly block 3;

[0033] like Figure 1 , 2 As shown in Figure 4, the square block 1 has a first surface and a second surface arranged opposite to each other. An assembly groove 2 is provided in the middle of the first surface. Four assembly blocks 3 are integrally formed at the four corners of the first surface of the square block 1. Multiple threaded holes 5 are provided on the bottom wall of the groove corresponding to the assembly groove 2 of the square block 1. Anchoring holes 6 are provided in the middle of the multiple assembly blocks 3.

[0034] In this embodiment, a steel reinforcement frame is embedded inside the square block 1; the square block 1 is integrally cast and its side wall is fixed with a nameplate.

[0035] The steel reinforcement cage can improve the overall strength performance of the square blocks, and the integrated standardized casting method can ensure the overall performance of the square blocks; the nameplate can display basic information such as the number, production date, and specifications of the square blocks, which facilitates the traceability of the square blocks.

[0036] To further optimize the above technical solution, the assembly slot 2 includes, but is not limited to, circular and square shapes, and the assembly block 3 includes, but is not limited to, fan-shaped and square shapes.

[0037] The shape of the assembly slot is adapted to the shape of the assembly block, specifically, the shape of at least four assembly blocks after splicing can be completely embedded in the assembly slot. Figure 1 and Figure 2 The assembly slot shown is circular, so the four assembly blocks are four sector-shaped structures. The four sector-shaped assembly blocks can be spliced ​​together to form a circle, and the four assembly blocks can be completely embedded in the assembly slot. The arc surface of the sector-shaped structure allows for some minor disturbances between the spliced ​​square blocks. Figure 4 The assembly slot shown is square, so the four assembly blocks are also square. Using square shapes can improve the splicing efficiency of square blocks, making construction more convenient and faster.

[0038] To further optimize the above technical solution and ensure the overall robustness of the assembled modules, the number of threaded holes 5 is the same as the number of assembly blocks 3.

[0039] In this embodiment, a groove 4 is provided on the side wall of the square block 1 away from the assembly groove 2 and circumferentially opposite to the threaded hole 5.

[0040] Example 2:

[0041] like Figure 3 and 5 As shown, this utility model embodiment discloses a modular pavement for road paving, which uses the modules in embodiment 1 for prefabricated pavement construction, and also includes a honeycomb metal frame 7; multiple square blocks 1 are provided and have upper and lower layers; the first surfaces of the multiple square blocks 1 in the upper and lower layers are arranged opposite each other; and the assembly block 3 of the same square block 1 in the lower layer is correspondingly embedded in the assembly groove 2 of the adjacent square block 1 in the upper layer; the two layers of square blocks 1 are connected by locking members; a groove for bonding lane lines is reserved on the second surface of the upper square block 1; the honeycomb metal frame 7 is laid on the subgrade layer, and concrete 8 is poured into the honeycomb holes of the honeycomb metal frame 7; a screw 9 is embedded in the concrete 8, and the screw 9 passes through the threaded hole 5 on the lower square block 1 to fasten the honeycomb metal frame 7 to the lower square block 1.

[0042] In this embodiment, the four assembly blocks 3 corresponding to the four square blocks 1 located in the lower layer are all embedded in the assembly groove 2 of one of the square blocks 1 located in the upper layer. The combined shape of the four assembly blocks 3 is adapted to the shape of the assembly groove 2.

[0043] As shown in the figure, the sidewalls of the square blocks abut each other and have two layers, with the lower layer of assembly blocks facing upwards and the upper layer of assembly slots facing downwards. Every four square blocks abut each other and their four assembly blocks form a group that can be combined to form a shape that fits the assembly slot. The four assembly blocks corresponding to the four square blocks can be completely embedded in the assembly slot of one of the upper square blocks. The upper and lower square blocks are connected by interlocking. At the relative edge of the road surface, a combination module that fits the design curve can be individually processed according to the design curve requirements. The standard module in this embodiment can be used at the middle of the road surface. The modular splicing method can improve construction efficiency and shorten the construction cycle. At the same time, the modular assembly does not generate construction waste, achieving standardized construction and making it more energy-saving and environmentally friendly.

[0044] See Figure 3 The upper and lower square blocks interlock and are connected by locking components to form the road structure layer. After concrete is poured inside the honeycomb metal frame, the road base layer is formed. The honeycomb metal frame is laid on the road subbase. By setting reserved screws in the honeycomb holes of the honeycomb metal frame, the connection between the lower square frame and the honeycomb metal frame is realized, thereby realizing the effective connection between the subgrade foundation and the road structure layer. This ensures the overall performance and stability of the road structure. When the subgrade is eroded and hollowed out, the road can still maintain normal traffic capacity due to the presence of the honeycomb metal frame.

[0045] In addition, when the road surface is damaged, it can be replaced simply by removing the square block corresponding to the damaged location, which reduces the road maintenance cost. Furthermore, since each square block has a nameplate, the same module can be traced back to its source for replacement.

[0046] When the road surface is demolished, the modules can be collected and reused. The modules in this embodiment can not only be used for road surface construction, but also for the prefabricated construction of roadbeds, guardrails, medians, curbs, etc., which can lead to a major trend in the field of civil engineering construction.

[0047] This embodiment has been tested and found that the overall maintenance cost of modular pavement is reduced by about 80% compared to traditional asphalt concrete pavement.

[0048] To further optimize the above technical solution, the locking component is a bolt, and the threaded end of the bolt is screwed into the threaded hole 5 of the upper square block and anchored in the anchoring hole 6 of the lower square block 1.

[0049] The threaded holes are evenly distributed along the bottom wall of the assembly groove, and the threaded holes of the upper assembly groove are arranged corresponding to the anchoring holes of the lower assembly block. The upper square block is connected to the four template bodies of the lower layer by bolts. The bolt nuts are located in the groove. The bolt nuts can be covered by a cap. The upper surface of the cap is flush with the upper surface of the road surface, which greatly ensures the quality of road construction.

[0050] To further optimize the above technical solution, multiple drainage grooves are provided on the second surface of the upper square block 1; the length direction of the drainage grooves is parallel to the driving direction.

[0051] Drainage channels ensure the road surface's drainage performance, reduce water mist generated by water accumulation between tires and road surface, and prevent vehicle skidding by extending the length of the drainage channels parallel to the vehicle's direction of travel. Furthermore, drainage channels reduce the contact area between the tires and the road surface, thereby reducing driving noise.

[0052] In other specific embodiments, refractory materials are added when making square blocks to improve the fire resistance of the road surface, which can effectively prevent the road surface from being burned by fire caused by traffic accidents.

[0053] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
