[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following is for reference. Figures 1-4 An embankment structure 100 according to an embodiment of the present invention is described.

[0039] like Figures 1-4 As shown, the embankment structure 100 according to an embodiment of the present invention includes: an embankment body 1, the embankment body 1 including a pavement layer 11, a plurality of subgrade filler layers 12 and a plurality of drainage components 13, the pavement layer 11, the plurality of subgrade filler layers 12 and the plurality of drainage components 13 being stacked along the height direction of the embankment structure 100, the pavement layer 11 being the uppermost layer, the plurality of subgrade filler layers 12 being respectively disposed between any two adjacent drainage components 13 and between the pavement layer 11 and adjacent drainage components 13, and the drainage components 13 having surfaces on both sides along the height direction of the embankment structure 100. Each surface is formed with a flow channel 131; fixed piles 2 are located inside the embankment body 1 and extend along the height direction of the embankment structure 100. The fixed piles 2 are installed in the pavement layer 11 and multiple subgrade filling layers 12, and multiple drainage components 13 are selectively installed in the fixed piles 2; multiple conductive connectors 3 are inserted into the corresponding subgrade filling layers 12 and fixedly connected to the fixed piles 2. The conductive connectors 3 are parallel to the horizontal plane or form an acute angle with the horizontal plane. The conductive connectors 3 are connected to the positive terminal of the power supply, and the drainage components 13 are connected to the negative terminal of the power supply.

[0040] In some embodiments of this application, there may be two subgrade filler layers 12 and three drainage components 13. Along the height direction of the embankment structure 100, the pavement layer 11, multiple subgrade filler layers 12, and multiple drainage components 13 are stacked, meaning they are arranged along the height direction of the embankment structure 100. The pavement layer 11 is located at the top. By setting multiple subgrade filler layers 12 and multiple drainage components 13 below the pavement layer 11, the load borne by the pavement layer 11 can be distributed, reducing the risk of emergency concentration of a single subgrade filler layer 12 or drainage component 13, thereby improving the structural reliability of the embankment body 1.

[0041] The uppermost subgrade filler layer 12 among the multiple subgrade filler layers 12 is located between the pavement layer 11 and the adjacent drainage component 13. The remaining subgrade filler layers 12 are located between any two adjacent drainage components 13, so that each drainage component 13 is adjacent to a subgrade filler layer 12. This arrangement can improve the stability of the drainage component 13, thereby reducing the risk of settlement or horizontal displacement of the drainage component 13, and thus helping the drainage component 13 to reliably perform its drainage function.

[0042] The drainage component 13 has a guide channel 131, which guides the infiltrated water at the drainage component 13. The flow of the infiltrated water within the guide channel 131 reduces the resistance and friction of the infiltrated water within the embankment structure 100, and allows the infiltrated water to be discharged along the extension direction of the guide channel 131, thereby improving the drainage efficiency of the drainage component 13. Along the height direction of the embankment structure 100, the guide channel 131 is formed on both sides of the drainage component 13. This arrangement allows for a reasonable layout of the guide channel 131, effectively increasing the drainage area without increasing the number of drainage components 13. This facilitates the simultaneous collection and discharge of more infiltrated water, further improving the drainage efficiency of the drainage component 13.

[0043] The fixed pile 2 is located within the embankment body 1. In some embodiments of this application, the fixed pile 2 can be formed by drilling a first strip-shaped hole in the embankment body 1, pre-embedding reinforcing bars, filling with crushed stone, and injecting grout into the hole. The fixed pile 2 extends along the height direction of the embankment structure 100 and penetrates the pavement layer 11 and multiple subgrade filler layers 12, so that the fixed pile 2, pavement layer 11, and subgrade filler layers 12 form a whole, thereby improving the integrity of the embankment structure 100. Multiple drainage elements 13 are selectively penetrated by the fixed pile 2. In some embodiments of this application, the fixed pile 2 does not penetrate the drainage elements 13 to improve the integrity of the drainage elements 13. In some embodiments of this application, the fixed pile 2 penetrates multiple drainage elements 13 so that the pavement layer 11, subgrade filler layer 12, and drainage elements 13 are connected as a whole through the fixed pile 2, thereby further improving the integrity of the embankment structure 100.

[0044] As some embodiments of this application, the reinforcing bars may be selected from those supported by vertical ribs and circumferential ribs.

[0045] Multiple conductive connectors 3 are respectively inserted into the corresponding subgrade filler layer 12 and fixedly connected to the fixed pile 2. Each subgrade filler layer 12 is provided with at least one conductive connector 3. The conductive connector 3 is inserted into the corresponding subgrade filler layer 12 and fixedly connected to the fixed pile 2. As some embodiments of this application, a second strip hole can be drilled on the embankment body 1, and then the conductive connector 3 is inserted into the second strip hole (one conductive connector 3 corresponds to one second strip hole), and the conductive connector 3 is inserted into the first strip hole (for example, inserted into the gravel in the first strip hole) so that the conductive connector 3 is fixedly connected to the fixed pile 2.

[0046] As some embodiments of this application, after the conductive connector 3 is inserted into the second and first slotted holes, grout (e.g., concrete) can be injected into the second and first slotted holes to fix the conductive connector 3 to the fixed pile 2. This can effectively improve the overall stability of the embankment structure 100.

[0047] The conductive connector 3 is parallel to the horizontal plane, or forms an acute angle with the horizontal plane, so that workers can arrange the conductive connector 3 according to the actual construction conditions, which helps to reduce the difficulty of arranging the conductive connector 3. This application uses the example of the conductive connector 3 forming an acute angle with the horizontal plane. The conductive connector 3 is connected to the positive terminal of the power supply, and the drainage component 13 is connected to the negative terminal of the power supply. It should be noted that by arranging the conductive connector 3 to form an acute angle with the horizontal plane, a potential difference can be reliably formed between the conductive connector 3 and the drainage component 13. This allows the infiltrated water in the embankment structure 100 to collect at the drainage component 13 under the action of the potential difference, and then be discharged from the embankment structure 100 through the diversion channel 131. This reduces the risk that the conductive connector 3 cannot form a potential difference with the drainage component 13 if it is arranged perpendicular to the horizontal plane, thereby improving the drainage effect of the embankment structure 100.

[0048] As some embodiments of this application, direct current can be used, with the voltage controlled at around 40V and the current controlled at around 10A. The power can be provided by solar energy, wind power, water power, or DC power supply.

[0049] As some embodiments of this application, the conductive connector 3 is made of steel reinforcement, for example, HRB400 steel reinforcement. As some embodiments of this application, the roadbed filler layer 12 uses stone chips, crushed stone, high liquid limit clay, and mixing water. Among them, the crushed stone can have two types: the first type of crushed stone has a particle size of any value between 5mm and 10mm, and the second type of crushed stone has a particle size of any value between 10mm and 16mm. The mass ratio of stone chips, the first type of crushed stone, the second type of crushed stone, high liquid limit clay, and mixing water is (265-275):(336-348):(624-648):(816-848):(246-250).

[0050] Specifically, in the embankment structure 100 proposed in this application, the pavement layer 11, multiple subgrade filler layers 12, and multiple drainage components 13 are stacked along the height direction of the embankment structure 100. The pavement layer 11 is located at the top, which can distribute the load borne by the pavement layer 11. Furthermore, the uppermost subgrade filler layer 12 is located between the pavement layer 11 and the adjacent drainage component 13, and the remaining subgrade filler layers 12 are respectively located between any two adjacent drainage components 13, which is conducive to the reliable drainage function of the drainage components 13. The drainage component 13 forms a guide channel 131, which can improve the drainage efficiency of the drainage component 13. Fixed pile 2 Located within the main body 1 of the embankment, multiple conductive connectors 3 are inserted into the corresponding subgrade filler layer 12 and fixedly connected to the fixed piles 2. This can effectively improve the overall stability of the embankment structure 100. The conductive connectors 3 are connected to the positive terminal of the power supply, and the drainage component 13 is connected to the negative terminal of the power supply. The conductive connectors 3 are arranged to form an acute angle with the horizontal plane, which can reliably form a potential difference between the conductive connectors 3 and the drainage component 13. This allows the infiltrated water in the embankment structure 100 to collect at the drainage component 13 under the action of the potential difference and be discharged from the embankment structure 100 through the diversion channel 131, thereby improving the drainage effect of the embankment structure 100.

[0051] Therefore, by setting multiple conductive connectors 3 to be inserted into the corresponding subgrade filler layer 12 and fixedly connected to the fixed pile 2, the embankment structure 100 can form a stable whole, which is beneficial to improving the integrity of the embankment structure 100. Furthermore, by connecting the conductive connectors 3 to the positive terminal of the power supply and the drainage component 13 to the negative terminal of the power supply, a potential difference can be formed between the conductive connectors 3 and the drainage component 13. This is beneficial to collect the infiltrated water in the embankment structure 100 to the drainage component 13 and discharge it from the embankment structure 100 through the diversion channel 131, thereby improving the drainage effect of the embankment structure 100, thereby improving the stability of the embankment structure 100 and extending its service life.

[0052] In some embodiments of the present invention, such as Figures 1-2 As shown, the conductive connector 3 is inserted into the corresponding roadbed filler layer 12 through the side wall of the corresponding roadbed filler layer 12.

[0053] In some embodiments of this application, a steel pipe can be inserted into the side of the corresponding subgrade fill layer 12 and the soil inside the steel pipe can be removed to form a second strip-shaped hole. For example, the soil inside the steel pipe can be removed using a auger. It should be noted that the steel pipe is a hollow steel pipe. After removing the soil inside the steel pipe, the conductive connector 3 can be inserted into the second strip-shaped hole, and then the steel pipe can be slowly removed.

[0054] The second strip hole is parallel to the horizontal plane, or forms an acute angle with the horizontal plane. By inserting the conductive connector 3 into the corresponding subgrade filler layer 12 from the side wall of the corresponding subgrade filler layer 12, it is easier to insert the conductive connector 3 into the corresponding subgrade filler layer 12, reducing the difficulty of arranging the conductive connector 3, thereby improving the arrangement efficiency of the conductive connector 3 and improving the construction efficiency of the embankment structure 100.

[0055] As some embodiments of this application, the end of the conductive connector 3 furthest from the fixed pile 2 can be externally connected to a second conductor, and the end of the conductive connector 3 furthest from the fixed pile 2 can be filled with hemispherical grout to protect the second conductor and embed the conductive connector 3 into the corresponding subgrade filler layer 12. For example... Figure 3 As shown, the hemispherical slurry can be a connecting cap 31. It should be noted that when pouring the connecting cap 31, the second wire needs to be buried in the connecting cap 31 so that the conductive connector 3 can be connected to the positive terminal of the power supply as the anode.

[0056] It should be noted that using the conductive connector 3 as the anode helps to slow down the corrosion of the conductive connector 3 and extend its service life. After inserting the conductive connector 3 into the second slot, the steel pipe can be slowly removed, and then the grout can be poured into the second slot.

[0057] In some embodiments of the present invention, such as Figures 1-2 As shown, the embankment structure 100 also includes a plurality of filter elements 4, which are respectively wrapped around the outside of the corresponding drainage elements 13.

[0058] The system comprises multiple drainage elements 13 and multiple filter elements 4, with each filter element 4 corresponding to one of the drainage elements 13, and each filter element 4 wrapping around the outside of its corresponding drainage element 13. As some embodiments of this application, the filter element 4 can be constructed as a non-woven geotextile. Non-woven geotextiles have high tensile strength, good permeability, high temperature resistance, freeze resistance, aging resistance, and corrosion resistance. Constructing the filter element 4 as a non-woven geotextile improves its reliability. By wrapping multiple filter elements 4 around the outside of their respective drainage elements 13, the probability of soil and gravel falling into the diversion channel 131 can be reduced, allowing infiltrated water to drain smoothly through the diversion channel 131, thus improving the drainage efficiency of the drainage element 13.

[0059] In some embodiments of the present invention, such as Figures 3-4 As shown, the conductive connector 3 is a metal part, and the drainage part 13 is a plastic part.

[0060] The conductive connector 3 is made of metal. In some embodiments of this application, the conductive connector 3 can be constructed as a reinforcing bar, for example, an HRB400 reinforcing bar. The drainage component 13 can be made of plastic. By constructing the conductive connector 3 as a metal component, it can have good conductivity, thereby reliably forming a potential difference between the conductive connector 3 and the drainage component 13. This allows infiltrated water in the embankment structure 100 to quickly collect at the drainage component 13, improving the drainage effect of the embankment structure 100. Furthermore, the high hardness of the metal component facilitates the insertion of the conductive connector 3 into the corresponding subgrade filler layer 12. By constructing the drainage component 13 as a plastic component, the production cost of the drainage component 13 can be reduced, which helps to lower the construction cost of the embankment structure 100. Moreover, the strong corrosion resistance of the plastic component helps to extend its service life.

[0061] In some embodiments of the present invention, such as Figure 4 As shown, the drainage component 13 has a wiring hole 132.

[0062] In this embodiment, the wiring hole 132 is a through hole. As some embodiments of this application, the wiring hole 132 can penetrate the drainage component 13 along the extension direction of the guide channel 131. The first wire can pass through the wiring hole 132 and can be connected to the negative terminal of a power supply, so that the drainage component 13 is connected to the negative terminal of the power supply. As some embodiments of this application, a plastic film with a certain protective function can be used to wrap the first wire. As some embodiments of this application, there can be multiple wiring holes 132. These multiple wiring holes 132 can be arranged at intervals along a direction perpendicular to the extension direction of the guide channel 131. This arrangement allows for the placement of multiple first wires, thereby reliably forming a potential difference between the conductive connector 3 and the drainage component 13, so that the infiltrated water within the embankment structure 100 can more quickly collect at the drainage component 13.

[0063] In some embodiments of the present invention, such as Figure 4 As shown, the drainage component 13 includes: a drainage component body 133, a plurality of first strip-shaped protrusions 134 and a plurality of second strip-shaped protrusions 135. Along the height direction of the embankment structure 100, the first surface of the drainage component body 133 is provided with a plurality of first strip-shaped protrusions 134, and two adjacent first strip-shaped protrusions 134 are spaced apart to form a guide channel 131. The second surface of the drainage component body 133 is provided with a plurality of second strip-shaped protrusions 135, and two adjacent second strip-shaped protrusions 135 are spaced apart to form a guide channel 131. The drainage component body 133 is provided with a wiring hole 132.

[0064] Along the height of the embankment structure 100, the main body 133 of the drainage component has opposing first and second surfaces. The first surface is provided with multiple first strip-shaped protrusions 134, which are spaced apart to form a guide channel 131 between each pair of adjacent first strip-shaped protrusions 134. Similarly, the second surface is provided with multiple second strip-shaped protrusions 135, which are also spaced apart to form a guide channel 131 between each pair of adjacent second strip-shaped protrusions 135. This arrangement allows guide channels 131 to be formed on both sides of the main body 133 of the drainage component, resulting in a reasonable arrangement of the guide channels 131. This effectively increases the drainage area, allowing more infiltrated water to be collected and discharged simultaneously, thereby further improving the drainage efficiency of the drainage component 13.

[0065] The main body 133 of the drainage component has a wiring hole 132. This arrangement can protect the first conductor in the wiring hole 132 through the main body 133 of the drainage component, which can reduce the probability of the infiltrated water in the diversion channel 131 coming into contact with the first conductor in the wiring hole 132, and help improve the safety of the embankment structure 100.

[0066] In some embodiments of the present invention, such as Figures 1-2 As shown, each subgrade filler layer 12 is provided with multiple conductive connectors 3. The multiple conductive connectors 3 on each subgrade filler layer 12 are arranged along the extension direction of the embankment structure 100. There are multiple fixed piles 2, which are arranged along the extension direction of the embankment structure 100. The conductive connectors 3 are fixedly connected to the corresponding fixed piles 2.

[0067] In some embodiments of this application, each subgrade fill layer 12 is provided with two, three, or more conductive connectors 3. The multiple conductive connectors 3 on each subgrade fill layer 12 are arranged along the extension direction of the embankment structure 100. The number of fixed piles 2 is also multiple, arranged along the extension direction of the embankment structure 100, and the conductive connectors 3 are fixedly connected to the corresponding fixed piles 2. In some embodiments of this application, the conductive connectors 3 and the corresponding fixed piles 2 can be cast as a single unit. By providing multiple conductive connectors 3 in each subgrade fill layer 12, the number of conductive connectors 3 is increased, thereby improving the collection efficiency of infiltrated water. Furthermore, by fixing the conductive connectors 3 to the corresponding fixed piles 2, the overall stability of the embankment structure 100 is improved.

[0068] In some embodiments of the present invention, such as Figure 2 As shown, each drainage component 13 includes multiple sub-drainage components 136, which are arranged sequentially along the horizontal plane and adjacent sub-drainage components 136 are spaced apart.

[0069] Each drainage component 13 includes multiple sub-drainage components 136, which are arranged sequentially along a horizontal plane and spaced apart. That is, every two adjacent sub-drainage components 136 are spaced apart, and the fixing pile 2 can be inserted between adjacent sub-drainage components 136. This arrangement reduces the probability that the fixing pile 2 will pass through the first conductor within the drainage component 13, thereby reducing the probability that the drainage component 13 cannot be connected to the negative terminal of the power supply due to the fixing pile 2 passing through the first conductor, which helps to reduce the loss rate of the drainage component 13. Furthermore, the sequential arrangement of multiple sub-drainage components 136 along a horizontal plane and the spacing between adjacent sub-drainage components 136 can also reduce the number of drainage components 13, thereby reducing the construction cost of the embankment structure 100.

[0070] In some embodiments of the present invention, such as Figure 2 As shown, multiple sub-drainage components 136 are spaced apart sequentially along the extension direction of the embankment structure 100, and along the height direction of the embankment structure 100, the orthographic projection of the conductive connector 3 on each subgrade filler layer 12 is offset from the orthographic projection of the sub-drainage component 136 of the adjacent drainage component 13.

[0071] Each drainage component 13 includes multiple sub-drainage components 136, which are arranged sequentially and spaced apart along the extension direction of the embankment structure 100. Furthermore, along the height direction of the embankment structure 100, the orthographic projection of the conductive connector 3 on each subgrade filler layer 12 is offset from the orthographic projection of the sub-drainage component 136 of the adjacent drainage component 13. In other words, along the height direction of the embankment structure 100, the orthographic projection of the conductive connector 3 on each subgrade filler layer 12 and the orthographic projection of the sub-drainage component 136 of the adjacent drainage component 13 do not overlap. This arrangement allows the conductive connectors 3 on each subgrade filler layer 12 to be rationally arranged with the sub-drainage components 136 of the adjacent drainage components 13, reducing the interference of the conductive connectors 3 (positive electrode) on each subgrade filler layer 12 with the adjacent drainage components 13 (negative electrode), thereby reliably forming a potential difference to collect the infiltrated water in the embankment structure 100 to the drainage component 13, which is beneficial to improving the drainage effect of the embankment structure 100.

[0072] like Figure 5 As shown, a construction method for an embankment structure according to an embodiment of the present invention is provided. The embankment structure is the embankment structure described in the above embodiment. The construction method includes:

[0073] S1, remove debris from the paving site and level the upper surface of the paving site, and lay a base layer on the paving site. Specifically, remove loose soil, loose stones, and debris from the paving site, level any protruding parts on the upper surface of the paving site, and then lay a base layer on the paving site, wherein the base layer can be a drainage mat.

[0074] S2 involves laying the main body of the embankment on top of the foundation layer and compacting and leveling the road surface layer.

[0075] The main body of the embankment consists of a pavement layer, multiple subgrade fill layers, and multiple drainage components. These layers are stacked along the height of the embankment structure. The subgrade fill layers are positioned between any two adjacent drainage components and between the pavement layer and adjacent drainage components, with the pavement layer at the top. The pavement layer is then compacted and leveled.

[0076] S3, drill a first strip hole extending along the height of the embankment structure on the main body of the embankment, and drill a second strip hole from the side of the subgrade fill layer into the corresponding subgrade fill layer, which is connected to the first strip hole.

[0077] As some embodiments of this application, a steel pipe can be inserted into the embankment body and the soil inside the steel pipe can be removed to form a first strip hole. In addition, a steel pipe can be inserted into the side of the corresponding subgrade fill layer and the soil inside the steel pipe can be removed to form a second strip hole. The soil inside the steel pipe can be removed by a spiral soil extractor. It is understood that the steel pipe is a hollow steel pipe.

[0078] S4, fill the first strip hole with the filling medium, and insert the conductive connector into the first strip hole and the second strip hole.

[0079] After the first strip hole is formed, the filling medium is filled into the first strip hole. The filling medium may include steel bars and gravel. The steel bars may be steel bars with vertical ribs and circumferential ribs for support. The conductive connector can be inserted into the second strip hole and the first strip hole from the end of the second strip hole away from the first strip hole. Specifically, the conductive connector can be inserted into the gravel filling the first strip hole.

[0080] S5, inject the grout into the first and second strip holes.

[0081] Specifically, the filling medium is filled into the first slot, and after the conductive connector is inserted into the first and second slots, the steel pipe can be slowly removed. Then, the grout is poured into the first and second slots to form a fixed pile in the first slot and to integrate the fixed pile with the conductive connector. It is understood that by pouring the grout into the second slot, the conductive connector and the grout can form a stable, high-strength, and reliable integral structure.

[0082] Specifically, remove loose soil, loose stones, and debris from the paving site, and level any protruding parts of the surface. Then, lay a base layer on the paving site, which can be a drainage cushion layer. Lay the main embankment on top of the base layer, and compact and level the pavement layer. The main embankment includes a pavement layer, multiple subgrade filler layers, and multiple drainage components. These layers are stacked along the height of the embankment structure. The subgrade filler layers are positioned between any two adjacent drainage components and between the pavement layer and adjacent drainage components, with the pavement layer on top. Compact and level the pavement layer.

[0083] A first strip-shaped hole extending along the height of the embankment structure is drilled in the main body of the embankment, and a second strip-shaped hole communicating with the first strip-shaped hole is drilled from the side of the corresponding subgrade fill layer into the subgrade fill layer. As some embodiments of this application, a steel pipe can be inserted into the main body of the embankment and the soil inside the steel pipe can be removed to form the first strip-shaped hole. Similarly, a steel pipe can be inserted into the side of the corresponding subgrade fill layer and the soil inside the steel pipe can be removed to form the second strip-shaped hole. The soil inside the steel pipe can be removed using a auger. It is understood that the steel pipe is a hollow steel pipe.

[0084] The filling medium is filled into the first strip-shaped hole, and the conductive connector is inserted into the first strip-shaped hole and the second strip-shaped hole. After the first strip-shaped hole is formed, the filling medium is filled into the first strip-shaped hole. The filling medium may include reinforcing bars and crushed stone. The reinforcing bars may be selected from those supported by vertical ribs and circumferential ribs. The conductive connector can be inserted into the second strip-shaped hole and the first strip-shaped hole from the end away from the first strip-shaped hole. Specifically, the conductive connector can be inserted into the crushed stone filling the first strip-shaped hole.

[0085] After filling the first slotted hole with the filling medium and inserting the conductive connector into both the first and second slotted holes, the steel pipe can be slowly removed. Then, the grout is injected into both the first and second slotted holes to form a fixed pile within the first slotted hole, integrating the fixed pile with the conductive connector. It is understood that by injecting the grout into the second slotted hole, the conductive connector and the grout can form a stable, high-strength, and reliable integral structure.

[0086] The above-described construction method allows multiple conductive connectors to be inserted into the corresponding subgrade fill layers and fixedly connected to the fixed piles, forming a stable whole for the embankment structure and improving its overall integrity. Furthermore, by connecting the conductive connectors to the positive terminal of the power supply and the drainage components to the negative terminal, a potential difference is created between them. This facilitates the collection of infiltrated water within the embankment structure at the drainage components, which is then discharged through a diversion channel, thus improving the drainage effect and enhancing the stability of the embankment structure, ultimately extending its service life. In addition, the above construction method is simple, efficient, and widely applicable, enabling the rapid and reliable construction of the embankment structure proposed in this application.
