Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to a modular splicing road with a special structure. Background Technology

[0002] Currently, highways are mainly constructed of two types: concrete-poured roads and asphalt concrete roads. Construction is slow, requires a large amount of earthwork and specialized equipment, resulting in high construction costs and long construction periods. Both types of roads are prone to cracking, collapse, unevenness, and wave-like defects during use, affecting vehicle safety. Some road surfaces also have weak subgrade foundations, requiring extensive earthwork for backfilling, and are susceptible to water erosion, posing safety risks. Furthermore, the subsequent maintenance costs are relatively high. To address these issues, we have proposed a modular splicing road with a special structure. Utility Model Content

[0003] This application provides a modular splicing road surface with a special structure, which completely solves the problems that currently exist in roads, such as unevenness, undulation, collapse, cracking, and the extensive use of earthwork in the roadbed.

[0004] This application provides a modular splicing road with a special structure, including a bottom impermeable layer, a concrete cushion layer above the impermeable layer, a hollow reinforced concrete structure above the concrete cushion layer, and a reinforced concrete sealing layer above the hollow reinforced concrete structure. The hollow reinforced concrete structure and the reinforced concrete sealing layer are both spliced ​​together.

[0005] Preferably, it also includes a vacuum high-strength wear-resistant layer disposed on the reinforced concrete sealing layer.

[0006] Preferably, the vacuum high-strength wear-resistant layer is provided with steel reinforcement bars.

[0007] Preferably, the bottom of the vacuum high-strength wear-resistant layer is provided with an arched groove.

[0008] Preferably, a wire is provided inside the arched groove.

[0009] Preferably, the wire is a heat-conducting coil or a temperature-sensing wire.

[0010] Preferably, the hollow reinforced concrete structure includes a steel reinforcement keel, concrete filling poured on the steel reinforcement keel, and multiple rectangular hollow grooves with equal spacing.

[0011] Preferably, anchoring bars are provided at the edges of the hollow reinforced concrete structure, the reinforced concrete sealing layer, and the vacuum high-strength wear-resistant layer; a connecting filling part is provided between adjacent hollow reinforced concrete structures, the reinforced concrete sealing layer, and the vacuum high-strength wear-resistant layer; the anchoring bars are located in the connecting filling part, and the connecting filling part is filled with concrete.

[0012] Preferably, the length-to-width ratio of the rectangular hollow groove on the hollow reinforced concrete structure is the golden ratio, and the length direction of the rectangular hollow groove is set along the length direction of the road surface.

[0013] Preferably, it also includes slope protection on both sides.

[0014] As can be seen from the above technical solutions, this application provides a modular splicing road with a special structure. According to the road plan, after the base course is compacted, a layer of rammed earth is first laid to form an anti-seepage layer, and then C20 concrete is poured to form a concrete cushion layer. The hollow reinforced concrete structure is hoisted onto the concrete cushion layer, and the hollow reinforced concrete structure is laid and aligned. The concrete cushion layer and the hollow reinforced concrete structure are connected by cement. Then, the connection between the hollow reinforced concrete structure and the hollow reinforced concrete structure is filled with concrete, and then a reinforced concrete sealing layer is laid. The laying of the reinforced concrete sealing layer is the same as the laying of the hollow reinforced concrete structure, thus completing the installation of the road surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up an impermeable layer and a concrete cushion layer, the foundation pit can be hardened, soil loss in the roadbed can be reduced, and the road surface can be leveled to facilitate subsequent installation.

[0017] 2. By using a hollow reinforced concrete structure, the road surface strength is improved while the amount of cement used is reduced. Furthermore, it exhibits excellent resistance to deformation under large temperature differences, thereby improving the quality of the roadside.

[0018] 3. By setting up a reinforced concrete sealing layer, the weight and impact force of the vehicle are evenly transferred to the hollow reinforced concrete structure. It plays a key role in connecting the upper and lower layers, ensuring that the vehicle does not fall into the hollow reinforced concrete structure, which has a special structure, and also ensuring the integrity of the road, the strength and smoothness of the road surface, and the protection against rainwater intrusion into the structural layer.

[0019] In summary, this application, through customized modular production in the factory, enables rapid assembly of highways. Furthermore, it saves raw materials, exhibits strong resistance to deformation, good integrity, high road surface smoothness, and is resistant to cracking and collapse. It can also be used in areas with large temperature differences, as the hollow reinforced concrete structure can offset deformation. Moreover, the hollow reinforced concrete structure forms a unified whole after paving, ensuring road integrity even after soil erosion, thus solving problems such as road cracking and collapse. Additionally, the road surface of this application has high smoothness, resulting in high vehicle safety and comfort. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] See Figure 1-5This application describes a modular splicing road with a special structure. It is applicable to the paving and installation of roads with weak subgrades, especially those experiencing severe road settlement and gravel roads. After installation, this road offers high flatness, smooth and safe driving, and a superior driving experience. Specifically, it includes a bottom impermeable layer 1, which is laid using a mixture of lime, sand, and clay to improve the stability of the road subbase. The impermeable layer 1 can be laid to a thickness of 200-400mm. Above the impermeable layer 1 is a concrete subbase 2, with a thickness that can be set within the range of 100±20mm. This subbase is used to level hardened road pits. The concrete subbase 2 can be constructed using C2 cement. 0. Concrete paving; The hollow reinforced concrete structure 3 located above the concrete subbase 2 is the main support for the pavement in this application. Therefore, the hollow reinforced concrete structure 3 is constructed using C30 concrete and a steel reinforcement skeleton, with a thickness of 300-600mm. The specific thickness can be set according to the road's weighing specifications. This structure can be manufactured in a factory and transported to the paving point for installation during the pavement construction phase; alternatively, a simple factory can be built on the roadside to produce a section of the pavement, enabling faster completion of the road paving; Reinforced concrete sealing located above the hollow reinforced concrete structure 3. Layer 4, the reinforced concrete sealing layer 4, is constructed by pouring C35 concrete, with a thickness of 100-350mm. Like the hollow reinforced concrete structure 3, it is centrally produced in a factory and transported to the construction site for installation. The connections between the concrete sub-layer 2, the hollow reinforced concrete structure 3, and the reinforced concrete sealing layer 4 are all secured with cement mortar. Furthermore, both the hollow reinforced concrete structure 3 and the reinforced concrete sealing layer 4 are spliced ​​together. After paving, the road surface exhibits good integrity, reducing earthwork and concrete usage while ensuring structural strength. Moreover, the road surface paved according to this application is less prone to cracking. Problems such as cracking, collapse, bulging, unevenness, and undulation may occur. It is especially suitable for poor roadbeds with gravel and loose soil, reducing the difficulty of paving and improving the service life of the road. It should be understood that in addition to using the original cement surface of the reinforced concrete sealing layer 4 as the road surface, concrete can also be laid on the road surface of this application as a concrete road surface. When laying the concrete road surface, emulsified asphalt needs to be laid on the reinforced concrete sealing layer 4 to increase the adhesion of the asphalt. When the reinforced concrete sealing layer 4 is directly used as the upper layer structure of the road surface, the thickness can be increased to 200-350mm.

[0029] In this utility model, on some special wear-resistant pavements, a vacuum high-strength wear-resistant layer 5 is also provided on the reinforced concrete sealing layer 4. The vacuum high-strength wear-resistant layer 5 is made of C35 concrete and has high wear resistance, which can improve the service life of the road. When the vacuum high-strength wear-resistant layer 5 is provided on the reinforced concrete sealing layer 4, the thickness of the reinforced concrete sealing layer 4 can be set at 100-150mm. The reinforced concrete sealing layer 4 and the vacuum high-strength wear-resistant layer 5 provide support together. The thickness of the vacuum high-strength wear-resistant layer 5 can be set at 50-200mm.

[0030] Furthermore, the vacuum high-strength wear-resistant layer 5 is equipped with steel reinforcement 51, which can provide the road surface with high load-bearing capacity and is suitable for heavy load road surfaces.

[0031] Furthermore, the bottom of the vacuum high-strength wear-resistant layer 5 is provided with an arched groove 6, which can reduce the amount of concrete used and the heat dissipation effect without affecting the load-bearing capacity of the vacuum high-strength wear-resistant layer 5.

[0032] Furthermore, the arched groove 6 is equipped with a conductor 8, which can be laid below the road surface for other purposes. Specifically, the conductor 8 is a heat-conducting coil or a temperature-measuring conductor. On special road surfaces, such as those with heavy snow accumulation, where manual cleaning is costly and disrupts normal traffic, a heat-conducting coil can be installed to heat the road surface, accelerate the melting of ice and snow, and ensure the smooth flow of traffic. The heat-conducting coil is located on the surface, resulting in high heating efficiency. In areas with abnormal road surface temperatures, a temperature-measuring conductor can also be installed to monitor the road surface temperature, allowing road maintenance personnel to promptly understand the road temperature information. Moreover, the temperature-measuring conductor is located inside the road, making the measurement more accurate. When the arched groove 6 is not equipped with a conductor 8, the thickness of the vacuum high-strength wear-resistant layer 5 can be set to 150-200mm. When the arched groove 6 is equipped with a conductor 8, the thickness of the vacuum high-strength wear-resistant layer 5 can be set to 50-100mm, reducing the thickness from the road surface.

[0033] In this utility model, the hollow reinforced concrete structure 3 includes a steel keel 33 and a concrete filling 32 poured on the steel keel 33, which can further improve the structural strength of the hollow reinforced concrete structure 3; and multiple rectangular hollow channels 31 with equal spacing. The setting of the rectangular hollow channels 31 not only saves materials, but also reduces the stress generated by the temperature of the concrete, and avoids road cracking.

[0034] Furthermore, anchoring bars 9 are provided at the edges of the hollow reinforced concrete structure 3, the reinforced concrete sealing layer 4, and the vacuum high-strength wear-resistant layer 5. A connecting filling part 7 is provided between adjacent hollow reinforced concrete structures 3, reinforced concrete sealing layers 4, and vacuum high-strength wear-resistant layers 5. The anchoring bars 9 are located in the connecting filling part 7, and the connecting filling part 7 is filled with concrete. During paving, a connecting filling part 7 is left between adjacent hollow reinforced concrete structures 3, reinforced concrete sealing layers 4, and vacuum high-strength wear-resistant layers 5 for pouring concrete. The connection relationship at the joint is strengthened by the anchoring bars 9, so that the road forms a whole. When the road surface and subgrade quality is poor, the road load can be distributed, thereby reducing the problems of road surface collapse, bulging, unevenness, and undulation. When the road surface is washed by rainwater and small-scale soil loss occurs, the road surface can also be kept flat, reducing the possibility of sudden road surface collapse, thus ensuring the safety of drivers.

[0035] In some embodiments, such as Figure 3 As shown, the connecting filling part 7 is set at the edge of the hollow reinforced concrete structure 3. During the pouring, the two sides are sealed and the pouring is completed in one go. The installation speed is fast. In order to maintain the consistency of the hollow reinforced concrete structure 3, it is necessary to reduce the thickness at the connecting edge of the hollow reinforced concrete structure 3 so that its thickness after pouring is consistent with other positions.

[0036] In some embodiments, such as Figure 4 As shown, the hollow reinforced concrete structure 3 is poured normally to ensure consistent thickness at each location. The anchoring connecting bar 9 extends outward by the length of a rectangular hollow groove 31 (which can complete a small portion of the pouring at the edge of the rectangular hollow groove 31). During the splicing process, a space of the length of a rectangular hollow groove 31 is left in the middle. The space of the rectangular hollow groove 31 is left at the pouring location for pouring other locations, completing the connection pouring of the hollow reinforced concrete structure 3, making it more consistent and the connection more stable.

[0037] Furthermore, the length-to-width ratio of the rectangular hollow channel 31 on the hollow reinforced concrete structure 3 is the golden ratio, that is, the length-to-width ratio of the rectangular hollow channel 31 satisfies the golden ratio. This structure has a strong load-bearing capacity, and when installed, the length direction of the rectangular hollow channel 31 is set along the length direction of the road surface, and the length direction is consistent with the driving direction. The hollow reinforced concrete structure 3 is optimal and can further improve the load-bearing capacity of the road.

[0038] This utility model also includes slope protection 10 on both sides to protect both sides of the road, protect the road sides and roadbed, and improve the service life of the road.

[0039] As can be seen from the above technical solution, according to the road plan, after the subgrade is compacted, a layer of rammed earth is first laid to form a seepage-proof layer 1, and then C20 concrete is poured to form a concrete cushion layer 2. The hollow reinforced concrete structure is hoisted onto the concrete cushion layer 2, and the hollow reinforced concrete structure 3 is laid and aligned. The concrete cushion layer 2 and the hollow reinforced concrete structure 3 are connected by cement. Then, the connection between the hollow reinforced concrete structure 3 and the hollow reinforced concrete structure 3 is filled with concrete, and then a reinforced concrete sealing layer 4 is laid. The laying of the reinforced concrete sealing layer 4 is the same as the laying of the hollow reinforced concrete structure 3, thus completing the road installation.
