[0020] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the content disclosed below.
[0022] The following is combined with Figures 1 to 4 to further illustrate the technical solution of the present invention.
[0023] The first embodiment is as Figures 1 to 4 shown: An anti-settlement municipal road structure, which includes: a subgrade 1, a cavity 2 is provided at the center inside the subgrade 1, a plurality of drain outlets 3 are arranged in a rectangular array on the lower end surface of the subgrade 1, an anti-overload settlement structure 4 is provided at the center of the upper end surface of the subgrade 1, a support and stabilization structure 6 is provided between the outer side wall of the subgrade 1 and the inside of the cavity 2, and a protection structure 5 is provided at the center of the lower end surface of the subgrade 1. The subgrade 1 discharges rainwater and the like out of the subgrade 1 through the drain outlets 3, reducing the influence of accumulated water on the subgrade 1. The anti-overload settlement structure 4 reduces the settlement during overload by increasing the bearing capacity of the subgrade 1. The support and stabilization structure 6 provides lateral support to enhance the stability of the subgrade 1. The protection structure 5 prevents moisture penetration and damage to the subgrade 1 caused by external factors.
[0024] The overload prevention and settlement structure 4 includes a compacted filler layer 401, a crushed stone base layer 402, a fine sand filler layer 403, and a cement stabilization layer 404. The compacted filler layer 401 is arranged at the center of the upper end face of the roadbed 1. The crushed stone base layer 402 is arranged at the center of the upper end face of the compacted filler layer 401. The fine sand filler layer 403 is arranged at the center of the upper end face of the crushed stone base layer 402. The cement stabilization layer 404 is arranged at the center of the upper end face of the fine sand filler layer 403. By compacting the compacted filler layer 401, the density of the roadbed 1 is increased, and the bearing capacity is improved. For the crushed stone base layer 402, the crushed stone has good water permeability and strength, can disperse the load, and reduce the settlement of the roadbed 1. For the fine sand filler layer 403, the fine sand fills the voids of the crushed stone base layer 402, increasing the integrity and stability of the roadbed 1. For the cement stabilization layer 404, the cement forms a bond with the fine sand, improving the strength and durability of the roadbed 1, being able to effectively share the load, improving the bearing capacity of the roadbed 1, and reducing overload settlement. The material of the compacted filler layer 401 is broken bricks and tiles. Materials such as broken bricks and tiles can fill the voids in the roadbed 1, increase the density of the roadbed 1, improve the bearing capacity and stability of the roadbed 1, and reduce settlement and deformation.
[0025] The protection structure 5 includes a drainage layer 501, an anti-seepage layer 502, a reinforcement layer 503, and the original soil 504. The drainage layer 501 is arranged at the center of the lower end face of the roadbed 1. The anti-seepage layer 502 is arranged at the center of the lower end face of the drainage layer 501. The reinforcement layer 503 is arranged at the center of the lower end face of the anti-seepage layer 502. The original soil 504 is arranged at the center of the lower end face of the reinforcement layer 503. The drainage layer 501 uses a water-permeable material to guide the water in the roadbed 1 to the outside, preventing the erosion of the roadbed 1 by accumulated water. The anti-seepage layer 502 can effectively prevent water from permeating, avoiding damage to the roadbed 1 by water. The reinforcement layer 503 increases the strength and stability of the roadbed 1, preventing the roadbed 1 from deforming under the action of the load. The original soil 504 serves as the base soil layer, providing support for the roadbed 1. The material of the anti-seepage layer 502 is high-density polyethylene. High-density polyethylene is a material with good anti-seepage performance. It can prevent water from permeating through, reduce the damage of water to the roadbed 1, and extend the service life of the road. The material of the reinforcement layer 503 is asphalt concrete. Asphalt concrete has high strength and stability, can increase the bearing capacity and anti-deformation ability of the roadbed 1, improve the durability and stability of the roadbed 1, and reduce cracks and deformation of the road surface.
[0026] The support and stability structure 6 includes multiple cross columns 601, two cross plates 602, two retaining walls 603 and multiple pile foundations 604. The multiple cross columns 601 are respectively arranged horizontally at the centers of the front and rear end faces of the roadbed 1. The two cross plates 602 are respectively arranged at the centers of the two side walls of the roadbed 1. The two retaining walls 603 are respectively arranged at the positions near the two sides of the center inside the cavity 2. The multiple pile foundations 604 are arranged in a rectangular pattern inside the cavity 2. The cross columns 601 and the cross plates 602 increase the lateral support of the roadbed 1 and improve the overall stability. The retaining walls 603 play a role of blocking and supporting on both sides inside the cavity 2 to prevent the soil outside the roadbed 1 from collapsing. The pile foundations 604 penetrate deep into the foundation. Through the friction between the pile foundations 604 and the soil and the bearing capacity at the ends of the pile foundations 604, the load of the roadbed 1 is shared, the bearing capacity of the roadbed 1 is improved, providing an all-round support and stability effect, enhancing the stability of the municipal road in the vertical and horizontal directions, effectively preventing the uneven settlement and deformation of the roadbed 1, ensuring the flatness and safety of the road, improving the bearing capacity of the foundation, and adapting to different geological conditions.
[0027] Working principle: The roadbed 1 discharges rainwater and the like through the drainage outlet 3 to reduce the influence of accumulated water on the roadbed 1. By compacting the filling layer 401, the compactness of the roadbed 1 is increased to improve the bearing capacity. For the crushed stone base layer 402, the crushed stone has good water permeability and strength, can disperse the load and reduce the settlement of the roadbed 1. For the fine sand filling layer 403, the fine sand fills the voids of the crushed stone base layer 402 to increase the integrity and stability of the roadbed 1. For the cement stabilized layer 404, the cement forms a bond with the fine sand to improve the strength and durability of the roadbed 1, can effectively share the load, improve the bearing capacity of the roadbed 1, and reduce the overloading settlement. The cross columns 601 and the cross plates 602 increase the lateral support of the roadbed 1 and improve the overall stability.
[0028] The retaining walls 603 play a role of blocking and supporting on both sides inside the cavity 2 to prevent the soil outside the roadbed 1 from collapsing. The pile foundations 604 penetrate deep into the foundation. Through the friction between the pile foundations 604 and the soil and the bearing capacity at the ends of the pile foundations 604, the load of the roadbed 1 is shared, the bearing capacity of the roadbed 1 is improved, providing an all-round support and stability effect, enhancing the stability of the municipal road in the vertical and horizontal directions, effectively preventing the uneven settlement and deformation of the roadbed 1, ensuring the flatness and safety of the road, improving the bearing capacity of the foundation, and adapting to different geological conditions. The drainage layer 501 uses a water-permeable material to guide the moisture in the roadbed 1 to the outside to prevent the erosion of the roadbed 1 by accumulated water. The anti-seepage layer 502 can effectively prevent the penetration of moisture and avoid the damage of the roadbed 1 by water. The reinforcement layer 503 increases the strength and stability of the roadbed 1 to prevent the deformation of the roadbed 1 under the action of the load. The original soil 504 serves as the foundation soil layer to provide support for the roadbed 1.
