[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A bridge head-free cone slope retaining wall type roadbed structure comprises a limit plate, a retaining wall, a soil foundation and a mold, wherein retaining walls are arranged on both sides of the soil foundation, limit plates are installed on the retaining walls, a mold is laid on the soil foundation between the retaining walls through the limit plates, and the interior of the mold is filled with a lime soil layer, a lime cement stabilized gravel soil layer and a cement concrete layer in sequence.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a slide groove is provided on the retaining wall, a slider is provided on the limiting plate, and the limiting plate is installed on the retaining wall through the cooperation between the slider and the slide groove.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Reliable structure: The cooperation between the slider and the slide groove forms a limit installation mechanism, which enables the limit plate to be firmly installed on the retaining wall. This enhances the stability of the entire structure and prevents displacement or swinging during use.

[0010] Easy maintenance: The slider and the slide groove limit mode is adopted, which is convenient for maintenance and replacement. If the limit plate needs to be maintained or updated, it can be disassembled and installed relatively easily, reducing the complexity of maintenance work.

[0011] Strong adaptability: The design of the slider and the chute increases the adaptability of the system, allowing the retaining wall to remain stable under different conditions. This is especially important for projects facing different terrain or climatic conditions, as it can adapt to changes in various environmental factors.

[0012] Shock absorption effect: The cooperation between the slider and the slide can achieve a certain shock absorption effect. When facing earthquakes or other external shocks, this design can slow down the force transmission of the retaining wall through a certain degree of sliding, which helps to reduce the vibration of the structure and improve the seismic performance of the entire system.

[0013] Convenient construction: When installing the limit plate, the design of the slider and the slide groove makes it relatively easy to position and install. This helps to improve construction efficiency and reduce manpower and time costs during the construction process.

[0014] Furthermore, the limiting plate is provided with a pin column, and the mold is penetrated with a through hole, and the mold is limitedly installed between the retaining walls through the cooperation between the through hole and the pin column.

[0015] The beneficial effects of adopting the above further scheme are:

[0016] Solid structure: The cooperation between the pin and the through hole forms a reliable limit connection, so that the mold can be firmly installed between the retaining walls. This design helps prevent the mold from shifting or tilting during use and improves the stability of the entire roadbed structure.

[0017] Easy to disassemble: The pin and through-hole design facilitates the disassembly and replacement of the mold. This is of great significance for maintaining, repairing or changing the shape of the roadbed structure, reducing the difficulty and time cost of maintenance work.

[0018] Precise positioning: The mold can be precisely positioned by the pin and through-hole limiter, which is critical to ensure the accurate formation of the roadbed structure and maintain the shape required by the design, and helps improve the construction quality.

[0019] Strong adaptability: The design of pins and through holes increases the adaptability of the system, allowing the mold to be accurately installed in different engineering projects and terrain conditions. This improves the flexibility and versatility of the structure.

[0020] Reduce construction difficulty: When installing the mold, the position of the mold can be relatively easily positioned through the cooperation between the pin and the through hole. This helps to improve construction efficiency and reduce manpower and time costs during the construction process.

[0021] Furthermore, the cross-section of the retaining wall is trapezoidal.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] Enhanced stability: Retaining walls with trapezoidal cross-sections are more stable than those with flat cross-sections. The wider base of the trapezoid helps to distribute and withstand the forces from soil and water pressure, reducing the risk of the structure overturning.

[0024] Better anti-overturning performance: Due to the trapezoidal cross-section design, the bottom width of the retaining wall is larger, which provides better anti-overturning performance. When facing the thrust of the soil, the trapezoidal cross-section can more effectively resist the overturning force.

[0025] Reduce structural weight: Compared with a wall of uniform thickness, the retaining wall with a trapezoidal cross-section can reduce the material usage of the upper structure, thereby reducing the overall structural weight while maintaining sufficient strength.

[0026] Better water flow guidance: The shape of the trapezoidal cross-section helps to guide the water flow and reduce the impact of water pressure on the retaining wall. This is an important consideration for the geographical environment where the retaining wall is located, such as construction projects near water areas.

[0027] Aesthetic appearance: The trapezoidal cross-section is usually more aesthetically appealing and is easier to integrate into the surrounding environment compared to traditional flat cross-sections, improving the landscape aesthetics.

[0028] Simplify construction: The retaining wall with a trapezoidal cross-section is easier to handle and install during the construction process because its geometric shape can reduce some complexities and simplify the earthwork.

[0029] Furthermore, the mold is in a U shape.

[0030] The beneficial effects of adopting the above further scheme are:

[0031] Easy to fill and remove air bubbles: The U-shaped mold design helps the uniform filling of concrete or other materials and reduces the generation of air bubbles. This helps to improve the density and quality of the formed structure.

[0032] Convenient demolding: The U-shaped mold usually makes the demolding process easier. Due to the depression on the inner surface of the mold, the edge part of the formed structure can be more easily removed from the mold, reducing the risk of damage.

[0033] Form concave-convex structure: The U-shaped mold design can form a structure with concave-convex features. This is necessary in some engineering applications, such as building elements that require texture or special shapes.

[0034] Flexibility: The U-shaped mold shape is usually more flexible and can adapt to different design requirements. This design allows the manufacture of structures with different shapes and styles on the same mold.

[0035] Reduce material usage: The design of the U-shaped mold can reduce the mold material used to a certain extent, reducing the manufacturing cost. At the same time, the concave shape can reduce the weight of the mold, making it easier to handle and transport.

[0036] Aesthetics: The shaped mold can create a structure with a unique appearance, increasing the beauty of the building or landscape design. This is an advantage for some projects that require a high appearance.

[0037] Adapt to complex structures: U-shaped molds are usually suitable for manufacturing some more complex structures, such as curved or curved architectural elements. This design helps to achieve more complex and delicate structures.

[0038] Furthermore, the retaining wall is prepared by mixing cement, sand, foaming agent, clay particles and polypropylene fibers.

[0039] The beneficial effects of adopting the above further scheme are:

[0040] Strength and stability: The combination of cement and sand usually provides high strength and stability, allowing the retaining wall to withstand soil pressure and other external forces, ensuring the soundness of the structure.

[0041] Lightweight design: Adding a foaming agent can form bubbles in the concrete, reducing the overall weight of the retaining wall while maintaining sufficient strength. This helps reduce the burden of the structure on the foundation and simplifies the construction and transportation process.

[0042] Application of clay particles: The use of clay particles can improve the performance of concrete and increase the permeability resistance and durability of retaining walls. Clay particles also have a certain degree of hygroscopicity, which helps to regulate the humidity of concrete.

[0043] Polypropylene fiber reinforcement: Adding polypropylene fiber can improve the crack resistance and toughness of the retaining wall, preventing the concrete from cracking when subjected to external forces. This helps increase the durability and service life of the retaining wall.

[0044] Material availability and cost-effectiveness: Cement, sand, foaming agent, clay particles and polypropylene fibers are relatively common and relatively low-cost building materials, which helps to reduce the manufacturing cost of retaining walls and ensures easy availability of materials.

[0045] Environmentally friendly properties: Mixing these materials to prepare retaining walls can help achieve some environmental goals. The use of foaming agents and lightweight design can reduce the demand for natural resources, while the use of clay particles can improve the sustainability of concrete.

[0046] Construction flexibility: The matching and mixing process of cement, sand, foaming agent, clay particles and polypropylene fiber is relatively flexible and adaptable, which is convenient for construction in various engineering environments and forming the required retaining wall structure.

[0047] Furthermore, the cement used is ordinary Portland cement with a strength of PO42.5; the sand is machine-made sand with a fineness modulus of 3.1; the foaming agent is plant protein with a dilution ratio of 1:50, and the bubble diameter produced by the foaming agent is less than 1 mm, and the bubble size is uniform; the bulk density of clay particles is 277 kg per cubic meter; the polypropylene fiber is a high-strength bundled monofilament fiber with a length of 12 mm and a diameter of 55 um.

[0048] The beneficial effects of adopting the above further scheme are:

[0049] Strength and durability: The use of high-quality materials such as ordinary Portland cement with a strength of PO42.5, machine-made sand and high-strength bundled monofilament fibers helps to improve the overall strength and durability of the retaining wall, making it more able to withstand external forces and environmental influences.

[0050] Lightweight design: The foaming agent uses plant protein, which can produce small and uniform bubbles in the concrete through a dilution ratio of 1:50, making the retaining wall lightweight and helping to reduce the weight of the overall structure while maintaining sufficient strength.

[0051] Evenly distributed bubbles: The bubbles produced by the foaming agent are less than 1mm in diameter and uniform in size, which helps to ensure even distribution of bubbles inside the concrete. This helps to improve the homogeneity of the concrete and increase the stability of the overall structure.

[0052] Application of clay particles: The bulk density of clay particles is 277 kg per cubic meter. The use of clay particles helps to improve the performance of concrete, increase its anti-permeability and durability, and provide a certain degree of moisture absorption.

[0053] High-strength polypropylene fiber: Using high-strength bundled monofilament fiber, polypropylene fiber with a length of 12mm and a diameter of 55um can effectively improve the crack resistance and toughness of concrete, making the retaining wall more capable of coping with external impacts and stresses.

[0054] Material synergy: The selection and configuration of these materials take into account their interaction in the concrete, and are able to synergistically play their respective advantages to achieve a balance in strength, lightness and durability of the retaining wall.

[0055] The beneficial effects of the utility model are:

[0056] Stable structure: The retaining wall made of cement, sand, foaming agent, clay particles and polypropylene fiber has high strength and stability. The cement is PO42.5 ordinary Portland cement, which has high compressive strength, so that the retaining wall can maintain structural integrity when subjected to pressure and load.

[0057] Preferred materials: Mechanically produced sand is a high-quality sand经过特殊处理的高质量砂,其细度模数为3.1,有助于提高混凝土的密实性和强度。同时,采用高强度束装单丝纤维的聚丙烯纤维,可以增强混凝土的抗裂性和韧性,使路基结构更加耐久。which has been specially processed, with a fineness modulus of 3.1, helping to improve the compactness and strength of concrete. At the same time, polypropylene fibers with high-strength bundled monofilaments can enhance the crack resistance and toughness of concrete, making the subgrade structure more durable.

[0058] Lightweight design: The use of a foaming agent makes the retaining wall have lightweight characteristics, effectively reducing the weight of the overall structure. The foaming agent is a plant-based protein, which produces small and uniform bubbles in the concrete, reducing the density of the retaining wall while maintaining sufficient strength.

[0059] Limiting device: By installing a limiting plate, designing sliders and chutes on the retaining wall, a reliable connection between the retaining wall and the soil subgrade is achieved. This design can effectively prevent the displacement and inclination of the retaining wall, improving the seismic resistance and stability of the entire subgrade structure.

[0060] Mold design: The mold采用凵状设计,内部依次填充石灰土层、石灰水泥稳定碎石土层和水泥混凝土层。这样的设计有助于形成均匀、强度适中的路基结构,同时使得施工过程更加简便和可控。is designed in a U shape, and is filled with a lime soil layer, a lime-cement stabilized crushed stone soil layer, and a cement concrete layer in sequence. Such a design helps to form a uniform and moderately strong subgrade structure, and at the same time makes the construction process simpler and more controllable.

[0061] Flexibility: By laying the mold on the soil subgrade through a limiting plate, the construction process is more flexible and can adapt to different terrains and engineering requirements. At the same time, the design of the mold allows for the easy formation of a layered structure of lime soil, stabilized crushed stone soil, and cement concrete in the subgrade structure.

[0062] Rational material ratio: The selection and ratio of various materials are carefully designed to ensure that the retaining wall has sufficient compressive and tensile properties. This can enhance the durability of the retaining wall and extend the service life of the entire subgrade structure.

[0073] Embodiment 1

[0074] A bridge-free conical slope retaining wall type roadbed structure comprises a limit plate 3, a retaining wall 4, a soil foundation 5 and a mold 7. The retaining wall 4 is arranged on both sides of the soil foundation 5. The cross section of the retaining wall 4 is a trapezoid. The retaining wall 4 with a trapezoidal cross section is more stable than that with a flat cross section. The bottom of the trapezoid is wider, which helps to disperse and bear the force from the soil and water pressure, and reduce the risk of overturning of the structure. Due to the design of the trapezoidal cross section, the bottom width of the retaining wall 4 is larger, which provides better anti-overturning performance. When facing the thrust of the soil, the trapezoidal cross section can more effectively resist the overturning force. Compared with a wall of uniform thickness, the retaining wall 4 with a trapezoidal cross section can reduce the weight of the overall structure by reducing the material usage of the upper structure while maintaining sufficient strength. The shape of the trapezoidal cross section helps to guide water flow and reduce the impact of water pressure on the retaining wall 4. This is an important consideration for the geographical environment where the retaining wall 4 is located, such as a construction project near a water area. The trapezoidal cross section is usually more aesthetically attractive and is easier to blend into the surrounding environment and improve the landscape aesthetics compared to the traditional flat cross section. The retaining wall 4 with a trapezoidal cross section is easier to handle and install during construction because its geometric shape can reduce some complexity and simplify earthwork. The retaining wall 4 is prepared by mixing cement, sand, foaming agent, clay particles and polypropylene fibers. The combination of cement and sand generally provides high strength and stability, so that the retaining wall 4 can withstand soil pressure and other external forces and ensure the firmness of the structure. The addition of a foaming agent can form bubbles in the concrete, reducing the overall weight of the retaining wall 4 while maintaining sufficient strength. This helps to reduce the burden of the structure on the foundation and simplify the construction and transportation process. The use of clay particles can improve the performance of concrete and increase the impermeability and durability of the retaining wall 4. Clay particles also have a certain degree of hygroscopicity, which helps to regulate the humidity of concrete. The addition of polypropylene fibers can improve the crack resistance and toughness of the retaining wall 4 and prevent cracks in the concrete when subjected to external forces. This helps to increase the durability and service life of the retaining wall 4. Cement, sand, foaming agent, clay particles and polypropylene fibers are relatively common and relatively low-cost building materials, which helps to reduce the manufacturing cost of the retaining wall 4 and ensure the easy availability of materials. Mixing these materials to create retaining walls4 can help achieve several environmental goals. The use of foaming agents and lightweight design can reduce the demand for natural resources, while the use of clay particles can improve the sustainability of concrete.The matching and mixing process of cement, sand, foaming agent, clay particles and polypropylene fiber is relatively flexible and adaptable, which is convenient for construction and forming the required retaining wall 4 structure in various engineering environments. The cement is ordinary Portland cement with a strength of PO42.5; the sand is machine-made sand with a fineness modulus of 3.1; the foaming agent is plant protein with a dilution ratio of 1:50. The bubble diameter of the foaming agent is less than 1mm and the bubble size is uniform; the clay particle packing density is 277 kg per cubic meter; the polypropylene fiber is a high-strength bundled monofilament fiber with a length of 12mm and a diameter of 55um. The selection of ordinary Portland cement with a strength of PO42.5, machine-made sand and high-strength bundled monofilament fiber and other high-quality materials helps to improve the overall strength and durability of the retaining wall 4, making it more able to withstand external forces and environmental influences. The foaming agent uses plant protein, which can produce small and uniform bubbles in the concrete through a dilution ratio of 1:50, making the retaining wall 4 lightweight, helping to reduce the weight of the overall structure while maintaining sufficient strength. The bubbles produced by the foaming agent are less than 1 mm in diameter and uniform in size, which helps to ensure the uniform distribution of bubbles inside the concrete. This helps to improve the homogeneity of the concrete and increase the stability of the overall structure. The bulk density of clay particles is 277 kg per cubic meter. The use of clay particles helps to improve the performance of concrete, increase impermeability and durability, and provide a certain degree of hygroscopicity. The use of high-strength bundled monofilament fibers, polypropylene fibers with a length of 12 mm and a diameter of 55 um, can effectively improve the crack resistance and toughness of concrete, making the retaining wall 4 more resistant to external impacts and stresses. The selection and configuration of these materials take into account their interaction in concrete, and can synergistically exert their respective advantages, thereby achieving a balance in the strength, lightness and durability of the retaining wall 4. A limit plate 3 is installed on the retaining wall 4, a slide groove 8 is opened on the retaining wall 4, and a slider 11 is provided on the limit plate 3. The limit plate 3 is installed on the retaining wall 4 through the cooperation of the slider 11 and the slide groove 8. The cooperation of the slider 11 and the slide groove 8 forms a limit installation mechanism, so that the limit plate 3 is firmly installed on the retaining wall 4. This enhances the stability of the entire structure and prevents displacement or swinging during use. The use of the slider 11 and the slide chute 8 to limit the position is convenient for maintenance and replacement. If the limit plate 3 needs to be maintained or updated, it can be relatively easy to disassemble and install, reducing the complexity of maintenance work. The design of the slider 11 and the slide chute 8 increases the adaptability of the system, so that the retaining wall 4 can remain stable under different conditions. This is particularly important for engineering projects facing different terrain or climatic conditions, because it can adapt to changes in various environmental factors. The mutual cooperation between the slider 11 and the slide chute 8 can achieve a certain shock-absorbing effect. In the face of earthquakes or other external shocks, this design can slow down the force transmission of the retaining wall 4 through a certain degree of sliding, which helps to reduce the vibration of the structure and improve the seismic performance of the entire system. When installing the limit plate 3, the design of the slider 11 and the slide chute 8 makes it relatively easy to position and install.This helps improve construction efficiency and reduce labor and time costs during construction. On the soil base 5, between the retaining walls 4, a mold 7 is laid through a limit plate 3. The limit plate 3 is provided with pin columns 9, and through holes 10 are formed through the mold 7. The mold 7 is limited and installed between the retaining walls 4 by the cooperation of the through holes 10 and the pin columns 9. The cooperation between the pin columns 9 and the through holes 10 forms a reliable limit connection, enabling the mold 7 to be stably installed between the retaining walls 4. This design helps prevent displacement or tilting of the mold 7 during use and improves the stability of the entire subgrade structure. The design of using the pin columns 9 and the through holes 10 facilitates the disassembly and replacement of the mold 7. This is of great significance for maintaining, repairing, or changing the shape of the subgrade structure, reducing the difficulty and time cost of maintenance work. Through the limiting method of the pin columns 9 and the through holes 10, precise positioning of the mold 7 can be achieved. This is particularly crucial for ensuring the accurate formation of the subgrade structure and maintaining the shape required by the design, helping to improve construction quality. The design of the pin columns 9 and the through holes 10 increases the adaptability of the system, enabling the mold 7 to be accurately installed under different engineering projects and terrain conditions. This improves the flexibility and versatility of the structure. When installing the mold 7, through the cooperation of the pin columns 9 and the through holes 10, the position of the mold 7 can be relatively easily positioned. This helps improve construction efficiency and reduce labor and time costs during construction. The mold 7 is in a U shape. The U-shaped design of the mold 7 helps the uniform filling of concrete or other materials and reduces the generation of air bubbles. This helps improve the compactness and quality of the formed structure. The U-shaped mold 7 usually makes the demolding process easier. Due to the depression on the inner surface of the mold 7, the edge part of the formed structure can be more easily removed from the mold 7, reducing the risk of damage. The U-shaped design of the mold 7 can form a structure with concave and convex features. This is necessary in some engineering applications, such as building elements that require textures or special shapes. The U-shaped shape of the mold 7 is usually relatively flexible and can adapt to different design requirements. This design allows the manufacture of structures with different shapes and styles on the same mold 7. The design of the U-shaped mold 7 can reduce the material of the mold 7 used to a certain extent and lower the manufacturing cost. At the same time, the concave shape can reduce the weight of the mold 7, making it easier to handle and transport. The U-shaped mold 7 can create a structure with a unique appearance, increasing the aesthetic feeling of building or landscape design. This is an advantage for some projects with high appearance requirements. The U-shaped mold 7 is usually suitable for manufacturing some relatively complex structures, such as curved or curvilinear building elements. This design helps achieve more complex and delicate structures. Lime soil layer 6, lime-cement stabilized crushed stone layer 2, and cement concrete layer 1 are sequentially filled inside the mold 7.

[0076] Structurally stable: The retaining wall 4 made of a mixture of cement, sand, foaming agent, clay pellets and polypropylene fibers has high strength and stability.

[0078] Lightweight design: The use of the foaming agent gives the retaining wall 4 lightweight characteristics, effectively reducing the weight of the overall structure. The foaming agent is a plant-based protein, which generates small and uniform bubbles in the concrete, reducing the density of the retaining wall 4 while maintaining sufficient strength.

[0079] Limiting device: By installing the limiting plate 3, designing the slider 11 and the chute 8 on the retaining wall 4, a reliable connection between the retaining wall 4 and the soil subgrade 5 is achieved. This design can effectively prevent the displacement and inclination of the retaining wall 4, improving the seismic resistance and stability of the entire subgrade structure.

[0080] Mold 7 design: The mold 7采用凵状设计 is designed in a U shape, and the lime soil layer 6, the lime-cement stabilized crushed stone layer 2 and the cement concrete layer 1 are filled in it in sequence. Such a design helps to form a uniform and moderately strong subgrade structure, and at the same time makes the construction process more simple and controllable.

[0081] Flexibility: By laying the mold 7 on the soil subgrade 5 through the limiting plate 3, the construction process is more flexible and can adapt to different terrains and engineering requirements. At the same time, the design of the mold 7 allows for the easy formation of a layered structure of lime soil, stabilized crushed stone soil and cement concrete in the subgrade structure.

[0082] Rational material ratio: The selection and ratio of various materials are carefully designed to ensure that the retaining wall 4 has sufficient compressive and tensile properties. This can enhance the durability of the retaining wall 4 and extend the service life of the entire subgrade structure.
