Description

Technical Field

[0001] This utility model relates to the field of road base material technology, and in particular to a water-resistant structure for a low-temperature molding road base material made of phosphogypsum. Background Technology

[0002] As an industrial byproduct, large-scale stockpiling of phosphogypsum not only occupies land resources but may also cause environmental pollution. With the continuous development of resource comprehensive utilization technology, the application of phosphogypsum in the field of road engineering has gradually attracted attention. Among them, low-temperature molding road base material of phosphogypsum, as a new type of environmentally friendly building material, has shown good application prospects in road construction because it can effectively utilize phosphogypsum resources, reduce production costs, and has certain mechanical properties.

[0003] Previously, most low-temperature molding road base materials made of phosphogypsum on the market focused on optimizing the mechanical properties of the materials and improving the low-temperature molding process. However, research and improvement on their water resistance performance were relatively lagging behind. Traditional phosphogypsum road base materials are usually prepared using simple physical mixing and compaction processes. During long-term use, external moisture such as rainwater and groundwater can easily seep into the road base through these pores and cracks, causing the base material to soften and its strength to decrease. This can lead to road damage such as frost heave and subsidence, seriously affecting the service life of the road and driving safety. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that in areas with frequent rainfall or high groundwater levels, road base materials are susceptible to water erosion. To address this, we propose a water-resistant structure for low-temperature molding of phosphogypsum road base materials.

[0005] To achieve the above objectives, this application adopts the following technical solution: a water-resistant structure for a low-temperature molded phosphogypsum road base material, comprising a road base material body, wherein an upper base layer is disposed inside the road base material body, an anti-seepage isolation layer is disposed inside the upper base layer, a lower base layer is disposed inside the anti-seepage isolation layer, and a bottom base layer is disposed inside the lower base layer. The surface material of the road base material body is a polymer-modified phosphogypsum composite material.

[0006] Preferably, the road base material body has a number of drainage holes inside.

[0007] Preferably, the top of the road base material body is provided with several drainage grooves.

[0008] Preferably, the material of the upper base layer is cement-stabilized phosphogypsum crushed stone.

[0009] Preferably, the material of the seepage-proof isolation layer is bentonite waterproof blanket.

[0010] Preferably, the material of the lower base layer is crushed stone.

[0011] Preferably, the material of the subbase is phosphogypsum stabilized soil.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the internal multi-layer material configuration effectively enhances the water resistance of the road base material. The upper base layer uses cement-stabilized phosphogypsum crushed stone, allowing water to quickly penetrate and drain through drainage holes, effectively preventing water accumulation inside the road base and ensuring the stability and durability of the entire road base structure. At the same time, the polymer-modified phosphogypsum composite material on the surface of the road base material has good weather resistance and wear resistance, which can extend the service life of the road.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a water-resistant structure for a low-temperature molded phosphogypsum road base material, comprising a road base material body 1, an upper base layer 3 disposed inside the road base material body 1, a seepage-proof isolation layer 4 disposed inside the upper base layer 3, a lower base layer 5 disposed inside the seepage-proof isolation layer 4, and a subbase layer 6 disposed inside the lower base layer 5. The surface material of the road base material body 1 is a polymer-modified phosphogypsum composite material. The arrangement of multiple layers of materials inside 1 effectively enhances the water-resistant performance of the road base material. The upper base layer 3 uses cement-stabilized phosphogypsum crushed stone material, allowing water to quickly penetrate and be discharged through drainage holes 2, effectively preventing water accumulation inside the road base and ensuring the stability and durability of the entire road base structure. At the same time, the polymer-modified phosphogypsum composite material on the surface of the road base material body 1 has good weather resistance and wear resistance, which can extend the service life of the road.

[0021] Reference Figure 2 and Figure 4 As shown in this embodiment, the road base material body 1 has several drainage holes 2 inside. The presence of several drainage holes 2 inside the road base material body 1 facilitates the drainage of water inside the road base material body 1, preventing water from staying inside the road base material body 1 for a long time. This prevents damage to the road base material body 1 caused by prolonged immersion in water, and improves the water resistance and service life of the road base material body 1.

[0022] Reference Figure 2 and Figure 4 As shown in this embodiment, the top of the road base material body 1 is provided with several drainage grooves 7. By providing several drainage grooves 7 on the top of the road base material body 1, the water that has penetrated into the road base material body 1 can be quickly discharged through the drainage grooves 7, avoiding the accumulation of water inside the road base material body 1, thereby effectively improving the water resistance of the road base material.

[0023] Reference Figure 3 As shown in this implementation scheme: the material of the upper base layer 3 is cement-stabilized phosphogypsum crushed stone. By setting the upper base layer 3 to be made of cement-stabilized phosphogypsum crushed stone, the road base material body 1 has higher strength and load-bearing capacity. At the same time, cement-stabilized phosphogypsum crushed stone also has good water resistance, which can effectively prevent water from penetrating into the interior of the road base material body, thereby improving the road's durability and service life. In addition, cement-stabilized phosphogypsum crushed stone also has good environmental performance, which can reduce the impact on the environment.

[0024] Reference Figure 3As shown in this embodiment, the material of the seepage-proof isolation layer 4 is bentonite waterproof blanket. By setting the seepage-proof isolation layer 4 to be made of bentonite waterproof blanket, it can effectively isolate water penetration and improve the water resistance of the road base material. Bentonite waterproof blanket has excellent waterproof performance and chemical corrosion resistance, and can maintain the stability and service life of the road for a long time. At the same time, bentonite waterproof blanket also has good flexibility and adaptability, and can adapt to the deformation and settlement of the road base material, further enhancing the overall stability and water resistance of the road base material.

[0025] Reference Figure 3 As shown in this implementation plan: the material of the lower base layer 5 is crushed stone. By setting the material of the lower base layer 5 as crushed stone, the permeability of the road base layer can be effectively improved, so that the road surface can drain water quickly in rainy weather, reduce water accumulation, and thus improve the driving safety and service life of the road. At the same time, the crushed stone lower base layer 5 also has good load-bearing capacity and stability, which can support the upper structure and prevent the road from collapsing or deforming.

[0026] Reference Figure 3 As shown in this implementation scheme, the subbase 6 is made of phosphogypsum-stabilized soil. By using phosphogypsum-stabilized soil for the subbase 6, the overall stability of the road base material 1 is enhanced. Simultaneously, phosphogypsum-stabilized soil has good water resistance, effectively preventing moisture from penetrating into the road base material 1, further improving the road's durability and service life. Furthermore, phosphogypsum-stabilized soil, as the material for the subbase 6, also has good environmental performance, meeting the requirements of sustainable development and contributing to the green development of the road construction industry.

[0027] Working Principle: The multi-layered internal structure (1) effectively enhances the water resistance of the road base material. The upper base layer (3) uses cement-stabilized phosphogypsum crushed stone, allowing water to quickly penetrate and drain through the drainage holes (2), effectively preventing water accumulation within the road base and ensuring the stability and durability of the entire road base structure. Simultaneously, the polymer-modified phosphogypsum composite material on the surface of the road base material (1) possesses excellent weather resistance and wear resistance, extending the road's service life. The numerous drainage holes (2) within the road base material (1) facilitate the drainage of accumulated water, preventing water buildup within the road base material itself. The water retention inside the base course material 1 for an extended period prevents damage caused by prolonged immersion in water, thus improving its water resistance and service life. The presence of several drainage channels 7 on the top of the base course material 1 allows water that has seeped into it to drain quickly, preventing water accumulation and effectively enhancing its water resistance. The use of cement-stabilized phosphogypsum crushed stone as the upper base course 3 further enhances the strength and load-bearing capacity of the base course material 1. Additionally, cement-stabilized phosphogypsum crushed stone also possesses excellent... Its excellent water resistance effectively prevents moisture from penetrating into the road base material, thereby improving the road's durability and service life. Furthermore, cement-stabilized phosphogypsum crushed stone also has good environmental performance, reducing its impact on the environment. The use of bentonite waterproof blankets as the seepage-proof isolation layer effectively isolates water penetration, improving the water resistance of the road base material. Bentonite waterproof blankets possess excellent waterproof performance and chemical corrosion resistance, maintaining the road's stability and service life for a long time. Simultaneously, bentonite waterproof blankets also have good flexibility and adaptability, accommodating deformation and settlement of the road base material, further enhancing the overall stability and resistance of the road base material. The permeability of the road base layer 5, made of crushed stone, is effectively improved, allowing for rapid drainage during rainy weather and reducing water accumulation. This enhances road safety and extends the road's lifespan. The crushed stone base layer 5 also possesses excellent load-bearing capacity and stability, supporting the superstructure and preventing road collapse or deformation. The subbase layer 6, made of phosphogypsum-stabilized soil, enhances the overall stability of the road base material 1.
