Description

Technical Field

[0001] This utility model relates to the field of roadbed anti-settlement technology, and in particular to a roadbed anti-settlement device. Background Technology

[0002] A roadbed is the foundation of a track or road surface, and is an earthwork structure formed through excavation or filling. The main function of a roadbed is to provide the necessary conditions for the laying of tracks or roads and the operation of trains or vehicles, and to bear the static and dynamic loads of tracks, locomotives, rolling stock, roads, and traffic loads, while transferring and dispersing the loads deep into the foundation.

[0003] This demonstrates that the stability of the roadbed has a significant impact on pavement performance. To prevent the roadbed from being eroded by rainwater, slope protection and drainage ditches are constructed on both sides of the roadbed to divert rainwater and prevent excessive erosion. Figure 1 As shown, the main body of the roadbed is constructed on the original soil layer, with drainage ditches on both sides. However, rainwater inevitably erodes and seeps into the roadbed, causing deformation within the roadbed and, with the pressure of vehicles, leading to roadbed collapse and settlement, thus affecting the service life of the highway. In light of the above, a roadbed anti-settlement device is proposed, which can effectively improve the situation of rainwater infiltration within the roadbed. Summary of the Invention

[0004] To address the problem of roadbed subsidence caused by rainwater erosion and infiltration, this invention provides a roadbed anti-settlement device. By arranging the anti-settlement device between the original soil layer and the main roadbed structure, the device can not only drain the eroded and infiltrated rainwater in a timely manner, preventing excessive moisture inside the main roadbed structure, but also provide support and bearing capacity for the main roadbed structure, reducing the possibility of roadbed subsidence and settlement.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A roadbed anti-settlement device is placed between the original soil layer and the main body of the roadbed, including several sets of bearing units arranged at intervals along the extension direction of the main body of the roadbed. Each set of bearing units includes multiple bearing mechanisms arranged at intervals along the width direction of the main body of the roadbed and a drainage pipe for connecting the multiple bearing mechanisms.

[0007] Each of the bearing mechanisms includes a hollow bearing column, a concrete column, and a bearing component. The bearing column is vertically embedded into the original soil layer, and the concrete column is provided on the bearing column. The concrete column is embedded into the original soil layer to facilitate anchoring the bearing column in the original soil layer and prevent the bearing column from sinking. The bearing column extends upward into the roadbed body and is connected to at least one bearing component to facilitate support of the bearing component.

[0008] The load-bearing component includes multiple load-bearing discs evenly arranged around the periphery of the load-bearing column. The multiple load-bearing discs and the load-bearing column are connected and combined to form an umbrella shape. The load-bearing discs are arranged at an angle, and a filter screen is provided on the upper surface of the load-bearing discs to prevent the roadbed body from intruding into the load-bearing discs. One end of each load-bearing disc is attached to the side wall of the load-bearing column, and the other end of the load-bearing disc extends outward and away from the load-bearing column.

[0009] The side wall of the bearing column is also provided with water holes. The bearing plate is tilted downward and communicates with the water holes to facilitate the flow of water into the bearing column. The bearing column is also provided with a water collection cylinder. The water holes and the water collection cylinder are connected vertically. The water flow in the bearing column eventually flows into the water collection cylinder. The drainage pipe is connected between the water collection cylinders on multiple bearing columns. The drainage pipe is arranged along the width of the roadbed body and extends out of the roadbed body at both ends to facilitate the discharge of water from the water collection cylinder.

[0010] Furthermore, the bearing column is a hollow steel column with a closed upper end to prevent the main body of the roadbed from entering the bearing column. The bearing column is equipped with reinforcing ribs to improve its own strength. The concrete column is a column made of reinforced concrete. The concrete column and the bearing column are connected and fixed. The diameter of the concrete column is larger than that of the bearing column, which plays a good anchoring role for the bearing column. The bearing column penetrates the concrete column vertically. The bearing column extends downward through the concrete column to the depth of the original soil layer. The bearing column extends upward through the concrete column to the main body of the roadbed.

[0011] Furthermore, at least one load-bearing component is arranged on the load-bearing column placed inside the roadbed body. The number of load-bearing components installed is selected according to the construction position of the load-bearing column. The load-bearing components and the concrete column are respectively arranged in the roadbed body and the original soil layer.

[0012] Furthermore, the bearing plate includes an upper inclined section and a lower inclined section, both of which are rectangular groove structures to facilitate the flow of rainwater. The concave direction of the upper inclined section faces the bearing column, while the concave direction of the lower inclined section faces away from the bearing column, making it easier for rainwater to enter the bearing plate. Filter screens are installed on both the upper and lower inclined sections to isolate the roadbed body and ensure an independent flow space for rainwater.

[0013] Furthermore, the upper inclined section is close to the supporting column at its upper end and far away from the supporting column at its lower end. The upper end of the upper inclined section is bent horizontally to form a horizontal section, which is fixedly connected to the side wall of the supporting column. The lower end of the upper inclined section is connected to the lower inclined section. The upper and lower inclined sections are arranged at a certain angle. The upper end of the lower inclined section is far away from the supporting column, and the lower end is fixedly connected to the supporting column.

[0014] Furthermore, the supporting column is provided with a mounting plate, and multiple reinforcing upper plates are provided between the supporting column and the mounting plate, which improves the installation strength of the mounting plate. The reinforcing upper plates correspond one-to-one with the supporting plates, and the horizontal section of the supporting plate overlaps on the mounting plate, ensuring the reliability of the upper support of the supporting plate. The supporting column is also provided with multiple reinforcing lower plates, and the reinforcing lower plates correspond one-to-one with the reinforcing upper plates. The end of the downward inclined section overlaps on the reinforcing lower plate, ensuring the reliability of the lower support of the supporting plate.

[0015] A through hole is provided at the junction of the upper inclined section and the lower inclined section, and the upper inclined section and the lower inclined section are connected through the through hole to ensure that rainwater can enter the lower inclined section; there are multiple water holes, and each water hole corresponds to a bearing plate, and the lower inclined section end of the bearing plate is connected to the water hole.

[0016] Furthermore, a flow interceptor is provided inside the support column, and multiple water outlet holes are opened around the perimeter of the support column. The water outlet holes are arranged above the flow interceptor to prevent the water in the support column from continuing to flow downward and to guide the water into the water collection cylinder.

[0017] The water collection cylinder is a cylindrical body, which is sleeved on the outside of the bearing column. The water collection cylinder is connected to the bearing column through the water outlet. Multiple bearing columns divide the drainage pipe into multiple sections. The multiple drainage pipe sections are arranged between two adjacent water collection cylinders, and the ends of two drainage pipe sections extend out of the roadbed body.

[0018] The beneficial effects of this utility model through the above technical solution are:

[0019] This utility model features a rational structural design. A load-bearing column is embedded within the original soil layer, extending downwards to increase the contact area with the original soil layer and ensure its stability. Simultaneously, concrete columns are arranged on top of the load-bearing column, improving the reliability of its embedding and preventing subsidence. Reinforcing ribs within the load-bearing column enhance its structural strength and facilitate the installation of load-bearing components.

[0020] This utility model allows for the installation of a corresponding number of load-bearing components depending on the location of the load-bearing column in the main body of the roadbed. After the load-bearing components and the load-bearing column are connected and combined, the cross-section is umbrella-shaped, which can provide sufficient support to support the main body of the roadbed, improve the load-bearing capacity of the roadbed, enhance the roadbed's resistance to deformation, and ensure the stability of the main body of the roadbed.

[0021] The bearing component of this utility model also has the function of rainwater diversion. The bearing plate in the bearing component can divert rainwater. The rainwater that infiltrates in the roadbed body enters the bearing column along the bearing plate and flows downward into the water collection cylinder. Finally, it is discharged from the roadbed body through the drainage pipe, which avoids the soil softening caused by the accumulation of rainwater in the roadbed body and ensures the safety of the roadbed body.

Detailed Implementation

[0032] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0033] like Figures 2-9As shown in the figure, a subgrade settlement prevention device is arranged between the original soil layer 1 and the subgrade main body 2, and the subgrade main body 2 is arranged above the original soil layer 1. The settlement prevention device includes a number of groups of bearing units arranged at intervals along the extension direction of the subgrade main body 2. Each group of bearing units includes five bearing mechanisms 5 arranged at intervals along the width direction of the subgrade main body 2 and a drain pipe 6 for connecting the five bearing mechanisms 5, as Figure 2 shown. The five bearing mechanisms 5 are arranged in a straight line. The bearing mechanism 5 can not only support the subgrade main body 2, but also has a water accumulation function. The water infiltrated in the subgrade main body 2 flows through the bearing mechanism 5 to the drain pipe 6 and is finally discharged from the subgrade main body 2.

[0034] In this embodiment, each bearing mechanism 5 includes a hollow bearing column 7, a concrete column 8 and a bearing component 9, as Figure 3 shown. The bearing column 7 is a hollow steel column with a closed upper end. The bearing column 7 is vertically embedded in the original soil layer 1. In order to improve the strength of the bearing column 7, reinforcing rib plates 10 are arranged in the bearing column 7. The reinforcing rib plates 10 penetrate through the entire bearing column 7. The cross section of the reinforcing rib plates 10 is similar to a "person" shape. Thus, the circular space of the bearing column 7 is evenly divided into three fan-shaped spaces by the reinforcing rib plates 10.

[0035] At the same time, in order to increase the stability and compressive capacity of the bearing column 7, a concrete column 8 is arranged on the bearing column 7. The concrete column 8 is a column body formed by casting reinforced concrete. The concrete column 8 is embedded in the original soil layer 1. Specifically, the steel bars inside the concrete column 8 are welded and fixed to the bearing column 7. Thus, after the concrete column 8 is cast and formed, the concrete column 8 and the bearing column 7 are connected and fixed. Moreover, the diameter of the concrete column 8 is much larger than the diameter of the bearing column 7, effectively preventing the bearing column 7 from descending under pressure.

[0036] The bearing column 7 vertically penetrates through the concrete column 8. The bearing column 7 extends downward through the concrete column 并延伸至原土层1深处,承载柱7向上穿过混凝土柱8延伸至路基主体2内。承载柱7向上延伸至路基主体2内、连接有至少一个承载组件9,也就是置于路基主体2内的承载柱7上布置有至少一个承载组件9,承载组件9和混凝土柱8上下分别布置在路基主体2和原土层1内。

[0037] The number of bearing components 9 is determined according to the arrangement position of the bearing mechanism 5. For the bearing mechanisms 5 near both sides of the subgrade main body 2, fewer bearing components 9 can be arranged thereon. For the bearing mechanisms 5 located in the middle of the subgrade main body 2, more bearing components 9 can be arranged thereon. Here, one bearing component 9 is arranged on the bearing columns 7 on both sides of the subgrade main body 2, and two bearing components 9 are arranged on the remaining bearing columns 7. The two bearing components 9 are arranged in a vertically offset manner.

[0038] It should be noted that there seems to be an incomplete sentence in the translation of . Please check and correct it if necessary.In this embodiment, the bearing component 9 includes three bearing disks 11 evenly arranged circumferentially around the bearing column 7. The bearing disks 11 can support the roadbed body 2 and simultaneously collect and guide infiltrated water into the bearing column 7. Figures 4-6 As shown.

[0039] The support plate 11 is arranged at an angle, and includes an upper inclined section 111 and a lower inclined section 112. The upper inclined section 111 and the lower inclined section 112 are arranged at a certain angle and are connected and fixed together. Both the upper inclined section 111 and the lower inclined section 112 are rectangular groove structures. The groove direction of the upper inclined section 111 faces the support column 7, and the groove direction of the lower inclined section 112 faces away from the support column 7. Figure 7 As shown.

[0040] In this way, the downward-flowing water in the main body of the roadbed 2 will flow into the upper inclined section 111 and the lower inclined section 112, and flow along the upper inclined section 111 and the lower inclined section 112, playing a certain guiding role. At the same time, a through hole 12 is provided at the junction of the upper inclined section 111 and the lower inclined section 112, connecting the two sections and ensuring that the water in the upper inclined section 111 flows into the lower inclined section 112. Figure 8 As shown.

[0041] To ensure sufficient flow space for water, a filter screen 13 is installed on the upper surface of the bearing plate 11, specifically on both the upper inclined section 111 and the lower inclined section 112. The filter screen 13 seals the openings of the grooves in the upper and lower inclined sections 111 and 112, thus isolating the roadbed body 2 and preventing it from encroaching into the upper and lower inclined sections 111 and 112. This allows water to flow freely within the bearing plate 11 without obstruction. To improve the compressive strength of the filter screen 13, multiple support strips 14 are evenly arranged within the upper and lower inclined sections 111 and 112. These support strips 14 support the filter screen 13, ensuring it is not deformed by pressure. Furthermore, the support strips 14 are comb-shaped and partially perforated, ensuring they do not impede the flow of water within the upper and lower inclined sections 111 and 112.

[0042] During installation, each support plate 11 has one end attached to the side wall of the support column 7, while the other end extends outward and away from the support column 7. Specifically, the upper inclined section 111 has its upper end close to the support column 7 and its lower end away from the support column 7. The upper end of the upper inclined section 111 is horizontally bent to form a horizontal section 15, which is fixedly connected to the side wall of the support column 7. The lower end of the upper inclined section 111 is connected to the lower inclined section 112, and the upper end of the lower inclined section 112 is away from the support column 7, while its lower end is fixedly connected to the support column 7.

[0043] To improve the reliability of the support plate 11 installation, a mounting plate 16 is provided on the support column 7. Three reinforcing upper plates 17 are provided between the support column 7 and the mounting plate 16 to support the mounting plate 16. The reinforcing upper plates 17 correspond one-to-one with the support plate 11. The horizontal section 15 of the support plate 11 overlaps on the mounting plate 16 and is welded and fixed to the mounting plate 16. At the same time, three reinforcing lower plates 18 are also provided on the support column 7. The reinforcing lower plates 18 correspond one-to-one with the reinforcing upper plates 17. The end of the downward inclined section 112 overlaps on the reinforcing lower plate 18 and is connected and fixed to the reinforcing lower plate 18. This ensures the reliable connection between the support plate 11 and the support column 7.

[0044] Three water holes 19 are provided on the side wall of the bearing column 7. Each water hole 19 corresponds to a bearing plate 11. The bearing plate 11 is inclined downward and communicates with the water holes 19. That is, the end of the downward inclined section 112 of the bearing plate 11 is connected to the water hole 19, so that the water flowing along the bearing plate 11 flows into the bearing column 7. At the same time, the filter screen 13 covers the water holes 19 to prevent the roadbed body 2 from entering the water holes 19 and blocking the water flow channel.

[0045] A water collection cylinder 20 is also provided on the supporting column 7. The water collection cylinder 20 is a cylindrical body and is fitted outside the supporting column 7. The water collection cylinder 20 is arranged between the concrete column 8 and the supporting component 9. The water hole 19 and the water collection cylinder 20 are connected vertically, so the water collected by the supporting plate 11 flows downward into the water collection cylinder 20. Specifically, a flow intercepting plate 21 is provided inside the supporting column 7. The flow intercepting plate 21 is circular and fits against the inner wall of the supporting column 7. The flow intercepting plate 21 divides the reinforcing rib plate 10 into upper and lower parts. At least three water outlet holes 22 are opened on the periphery of the supporting column 7. The water outlet holes 22 are arranged above the flow intercepting plate 21. The water collection cylinder 20 is connected to the supporting column 7 through the water outlet holes 22, so the water in the supporting column 7 is discharged into the water collection cylinder 20 through the water outlet holes 22.

[0046] The drainage pipe 6 is arranged along the width of the roadbed body 2, with both ends of the drainage pipe 6 extending out of the roadbed body 2. The drainage pipe 6 is connected between the water collection cylinders 20 on multiple bearing columns 7. The multiple bearing columns 7 divide the drainage pipe 6 into multiple segments, and the multiple segments of the drainage pipe 6 are arranged between two adjacent water collection cylinders 20. The ends of two of the drainage pipe segments 6 extend out of the roadbed body 2, thereby draining water from the roadbed body 2.

[0047] The principle of this utility model is as follows: First, the bearing column 7 is rammed into the original soil layer 1. Then, a steel cage is arranged at the corresponding position of the bearing column 7, and concrete is poured to form a concrete column 8, ensuring the stability of the bearing column 7 installation. Multiple bearing columns 7 are constructed in the above manner, and then drainage pipes 6 are used to connect the bearing columns 7 one by one. The main body of the roadbed 2 is constructed layer by layer, and the bearing components 9 are installed sequentially during construction.

[0048] Sufficient support is provided to the roadbed body 2 and bearing components 9 by the bearing columns 7 and concrete columns 8, reducing the settlement of the roadbed body 2. When water seepage occurs in the roadbed body 2, rainwater flows downward into the bearing plate 11 and, guided by the bearing plate 11, enters the bearing column 7 through the water hole 19. Finally, the rainwater enters the water collection cylinder 20 through the water outlet 22 and is discharged by the drainage pipe 6. This ensures timely discharge of infiltrated rainwater, avoids rainwater accumulation, and minimizes the possibility of deformation and collapse of the roadbed body 2.

[0049] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
