The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 5 An embankment structure 100 according to an embodiment of the present invention is described.

[0028] like Figure 1-Figure 5 As shown, the embankment structure 100 according to the embodiment of the present invention includes: an embankment body 10 , a first prefabricated wall 20 , a second prefabricated wall 30 , a geogrid 40 and a drainage mat 50 .

[0029] The first prefabricated wall 20 is arranged at the top of the embankment body 10 and part of the structure is embedded in the embankment body 10. The second prefabricated wall 30 is arranged at the bottom of the embankment body 10 and part of the structure is embedded in the embankment body 10. The top of the first prefabricated wall 20 has a first protrusion 21, and the top of the second prefabricated wall 30 has a second protrusion 31. Figure 1 The geogrid 40 is arranged below the embankment structure 100 ; and the drainage mat 50 is buried in the embankment body 10 .

[0030] Among them, the embankment body 10 has a slope top and a slope bottom, the first prefabricated wall 20 is arranged at the slope top of the embankment body 10, and part of the structure of the first prefabricated wall 20 is embedded in the embankment body 10, the second prefabricated wall 30 is arranged at the slope bottom of the embankment body 10, and part of the structure of the second prefabricated wall 30 is embedded in the embankment body 10, the top of the first prefabricated wall 20 has a first protrusion 21, and the top of the second prefabricated wall 30 has a second protrusion 31.

[0031] By providing the first prefabricated wall 20 with a first raised portion 21 at the top and the second prefabricated wall 30 with a second raised portion 31 at the top, the surfaces of the first prefabricated wall 20 and the second prefabricated wall 30 can be designed to be concave and convex to disperse the impact force of the water flow, thereby reducing the erosion of the embankment body 10 and significantly improving the anti-scouring ability of the embankment body 10.

[0032] As some embodiments of the present application, the first prefabricated wall 20 and the second prefabricated wall 30 are both designed in a modular manner, and the first prefabricated wall 20 and the second prefabricated wall 30 can be prefabricated. By making the first prefabricated wall 20 and the second prefabricated wall 30 both designed in a modular manner and both prefabricated, the design difficulty of the first prefabricated wall 20 and the second prefabricated wall 30 can be reduced, and the production efficiency of the first prefabricated wall 20 and the second prefabricated wall 30 can be improved.

[0033] As some embodiments of the present application, the first prefabricated wall 20 and the second prefabricated wall 30 are both integrally formed, that is, the first prefabricated wall 20 and the second prefabricated wall 30 are both constructed as an integrally formed part. By constructing the first prefabricated wall 20 and the second prefabricated wall 30 as an integrally formed part, the structural strength of the first prefabricated wall 20 and the second prefabricated wall 30 can be improved, and the anti-scouring performance of the first prefabricated wall 20 and the second prefabricated wall 30 can be improved.

[0034] As some embodiments of the present application, the first prefabricated wall 20 and the second prefabricated wall 30 can fit tightly with the embankment body 10, and the self-weight and structural rigidity of the first prefabricated wall 20 and the second prefabricated wall 30 can provide support for the slope of the embankment body 10, which can effectively reduce the risk of soil slippage and settlement of the embankment body 10.

[0035] Along the height direction of the embankment structure 100 (i.e. Figure 1 The geogrid 40 is disposed below the embankment structure 100. As some embodiments of the present application, one end of the geogrid 40 can abut against the second prefabricated wall 30. Such an arrangement can provide support for the second prefabricated wall 30 and improve the structural strength of the embankment structure 100. In addition, the geogrid 40 can reduce the probability of the soil of the embankment body 10 sliding on the slope.

[0036] As some embodiments of the present application, the geogrid 40 has a grid structure, and the geogrid 40 can firmly bind the soil particles of the embankment body 10 together through the grid structure, reducing the probability of soil sliding on the slope. In addition, the geogrid 40 can form a tensile force on the soil, increase the overall shear strength of the embankment structure 100, and significantly improve the anti-slip performance of the embankment structure 100.

[0037] The geogrid 40 is made of light material and is easy to lay. It can adapt to irregularly shaped embankment structures 100 and is easy to construct, which is beneficial to improving construction quality.

[0038] As some embodiments of the present application, the geogrid 40 has a sand cushion layer 71 , and the geogrid 40 may be wrapped with an anti-filtration geotextile to improve the anti-slip performance and service life of the geogrid 40 .

[0039] The drainage pad 50 is buried in the embankment body 10. The number of the drainage pad 50 can be multiple, and the number of the drainage pad 50 can be but not limited to two, three, four, etc. As some embodiments of the present application, along the height direction of the embankment structure 100 (i.e. Figure 1 The three drainage pads 50 are arranged in sequence, and the drainage pads 50 are used to guide the water in the embankment body 10 to the slope surface, reduce the water pressure inside the embankment body 10, and reduce the risk of slippage of the embankment structure 100.

[0040] As some embodiments of the present application, a layer of drainage mat 50 can be laid after part of the soil of the embankment body 10 is filled, and soil filling can be continued after laying the drainage mat 50. This can ensure that the moisture of the embankment structure 100 is evenly discharged without accumulation, and can maintain the dryness of the inside of the embankment body 10.

[0041] As some embodiments of the present application, the embankment structure 100 further includes a drainage ditch, and water directed toward the slope surface can flow into the drainage ditch.

[0042] As some embodiments of the present application, before construction, first, it is necessary to clean the construction site, mark the lines and position them according to the drawings, so as to ensure that the first prefabricated wall 20, the second prefabricated wall 30, the geogrid 40, the drainage mat 50 and the like are accurately positioned. Then, a layer of geogrid 40 is laid at the foot of the slope, and the tightness of the geogrid 40 in the soil is ensured by tensioning and fixing to enhance the anti-slip ability of the embankment structure 100. Then, the earthwork is filled layer by layer from the foot of the slope, and compacted to ensure that the density meets the requirements, and after each layer of soil is filled, a layer of drainage mat 50 is laid. Then, the first prefabricated wall 20 and the second prefabricated wall 30 are installed at the top and foot of the slope of the embankment structure 100. Then, a drainage ditch is set according to the design drawings, and the drainage mat 50 is connected to the drainage ditch to ensure that the internal moisture of the embankment structure 100 is discharged in the later stage. Finally, a walkway layer is laid on the top of the embankment structure 100 to facilitate daily inspection and maintenance by construction workers. The walkway layer is paved with flat materials to ensure smooth passage.

[0043] It should be noted that by setting the first prefabricated wall 20 and the second prefabricated wall 30, the embankment structure 100 can be provided with anti-scour protection and the embankment structure 100 can be reinforced and supported. By setting the geogrid 40, the anti-slip performance and overall stability of the embankment structure 100 are significantly improved, and the risk of soil landslides in the embankment structure 100 is reduced. By setting the drainage mat 50, the embankment structure 100 can achieve efficient drainage and uniform water conduction, and the probability of particle loss in the embankment structure 100 can be reduced.

[0044] Therefore, by providing the first prefabricated wall 20 with a first protrusion 21 at the top and the second prefabricated wall 30 with a second protrusion 31 at the top, the scour resistance of the embankment structure 100 can be improved. By arranging the geogrid 40 under the embankment structure 100, the anti-slip performance of the embankment structure 100 can be improved. By burying the drainage mat 50 in the embankment body 10, the drainage effect of the embankment structure 100 can be significantly improved. The combined application of the first prefabricated wall 20, the second prefabricated wall 30, the geogrid 40 and the drainage mat 50 is beneficial to improving the stability and reliability of the embankment structure 100.

[0045] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, along the slope top to the slope bottom direction (i.e. Figure 1 The levels of at least a portion of the upper surface of the first prefabricated wall 20 and at least a portion of the upper surface of the second prefabricated wall 30 gradually decrease.

[0046] Among them, along the direction from the top to the bottom of the slope (i.e. Figure 1 The horizontal height of at least a part of the upper surface of the first prefabricated wall 20 gradually decreases, and the horizontal height of at least a part of the upper surface of the second prefabricated wall 30 gradually decreases, that is, along the direction from the top of the slope to the bottom of the slope (i.e. Figure 1 In the X direction shown in FIG. 1 , at least a portion of the upper surface of the first prefabricated wall 20 and at least a portion of the upper surface of the second prefabricated wall 30 are both gradually inclined and extended downward.

[0047] As some embodiments of the present application, the levels of a portion of the upper surface of the first prefabricated wall 20 and a portion of the upper surface of the second prefabricated wall 30 gradually decrease.

[0048] As some embodiments of the present application, the surfaces of the first prefabricated wall 20 and the second prefabricated wall 30 are both constructed as a stepped structure. Such a configuration can disperse the impact of water flow on the first prefabricated wall 20 and the second prefabricated wall 30, reduce the erosion of water flow on the soil of the embankment structure 100, and significantly improve the anti-scouring performance of the embankment structure 100.

[0049] From the top to the bottom of the slope (i.e. Figure 1 By gradually lowering the level of at least a portion of the upper surface of the first prefabricated wall 20 and at least a portion of the upper surface of the second prefabricated wall 30, the impact of water flow can be effectively mitigated, and the embankment structure 100 can be facilitated to utilize the dead weight of water to move along the direction from the top of the slope to the bottom of the slope (i.e. Figure 1 Draining and guiding water in the X direction as shown in the figure is beneficial to improving the drainage performance of the embankment structure 100.

[0050] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the first prefabricated wall 20 has a third protrusion 22 protruding toward the embankment body 10. Specifically, the third protrusion 22 is embedded in the embankment body 10, and the third protrusion 22 is arranged to protrude toward the embankment body 10. By making the first prefabricated wall 20 have the third protrusion 22 protruding toward the embankment body 10, the first prefabricated wall 20 and the embankment body 10 can be anchored together, which can improve the reliability of fixing the first prefabricated wall 20 and the embankment body 10, and can improve the structural stability of the embankment structure 100, which is beneficial to improving the anti-slip performance of the embankment structure 100.

[0051] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, part of the structure of the second prefabricated wall 30 is buried in the ground and has a fourth protrusion 32. In other words, the part of the structure of the second prefabricated wall 30 buried in the ground has a fourth protrusion 32. By burying part of the structure of the second prefabricated wall 30 in the ground and having the fourth protrusion 32, the second prefabricated wall 30 can be anchored to the ground, which can improve the fixation reliability of the second prefabricated wall 30 to the ground and the embankment body 10, and can improve the structural stability of the embankment structure 100, which is beneficial to improving the anti-slip performance of the embankment structure 100.

[0052] In some embodiments of the present invention, Figure 3 As shown, there are a plurality of first prefabricated walls 20 and a plurality of second prefabricated walls 30, and the plurality of first prefabricated walls 20 are arranged along a first direction (ie Figure 2 The plurality of second prefabricated walls 30 are connected in sequence along the first direction (ie, the Y direction shown in FIG. Figure 2 The Y direction shown in FIG. 1 is the height direction of the embankment structure 100 (i.e. Figure 1 The Z direction shown is perpendicular to the

[0053] The number of the first prefabricated walls 20 is multiple, and the number of the first prefabricated walls 20 can be but is not limited to two, three, four, etc. As some embodiments of the present application, the number of the first prefabricated walls 20 is four, and the four first prefabricated walls 20 are arranged along the first direction (i.e. Figure 2 The two components are connected in sequence (in the Y direction shown).

[0054] The connection method of each two adjacent first prefabricated walls 20 can be but is not limited to concrete connection, anchor connection, etc. As some embodiments of the present application, each two adjacent first prefabricated walls 20 are connected by anchors. When producing the first prefabricated walls 20, a first anchor hole can be left inside the first prefabricated wall 20. The anchor can be fixed in cooperation with the first anchor hole, and the anchor can be connected between two adjacent first prefabricated walls 20 to connect multiple first prefabricated walls 20 in sequence.

[0055] The number of the second prefabricated walls 30 is multiple, and the number of the second prefabricated walls 30 can be but is not limited to two, three, four, etc. As some embodiments of the present application, the number of the second prefabricated walls 30 is four, and the four second prefabricated walls 30 are arranged along the first direction (i.e. Figure 2 The two components are connected in sequence (in the Y direction shown).

[0056] The connection method of each two adjacent second prefabricated walls 30 can be but is not limited to concrete connection, anchor connection, etc. As some embodiments of the present application, each two adjacent second prefabricated walls 30 are connected by anchors. When producing the second prefabricated walls 30, a second anchor hole can be left inside the second prefabricated wall 30. The anchor can be fixed in cooperation with the second anchor hole, and the anchor can be connected between two adjacent second prefabricated walls 30 to connect multiple second prefabricated walls 30 in sequence.

[0057] It should be noted that the first direction (i.e. Figure 2 The Y direction shown in FIG. 1 is the height direction of the embankment structure 100 (i.e. Figure 1 The Z direction shown in the figure) are perpendicular to each other, and the first direction (i.e. Figure 2 Y direction shown) and Figure 1 The X direction is shown as vertical.

[0058] Such a configuration enables multiple first prefabricated walls 20 to form a stable overall supporting structure, and enables multiple second prefabricated walls 30 to form a stable overall supporting structure, which can improve the overall stability of the embankment structure 100, and can improve the anti-slip performance of the embankment structure 100, and reduce the risk of soil landslides in the embankment structure 100.

[0059] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the second prefabricated wall 30 has a first recessed portion 33 and a drainage channel 34 . The drainage channel 34 is located on a side of the first recessed portion 33 away from the embankment body 10 and is connected to the first recessed portion 33 . The first recessed portion 33 is filled with crushed stones.

[0060] Among them, the first recessed portion 33 has a side away from the embankment body 10 and a side close to the embankment body 10, the drainage channel 34 is located on the side of the first recessed portion 33 away from the embankment body 10, and the drainage channel 34 is connected to the first recessed portion 33, and the first recessed portion 33 is filled with gravel.

[0061] By providing the second prefabricated wall 30 with a first recessed portion 33 and filling the first recessed portion 33 with gravel, the embankment structure 100 can have a filtering function, and by connecting the drainage channel 34 with the first recessed portion 33, water in the first recessed portion 33 can flow out through the drainage channel 34, thereby improving the drainage effect of the embankment structure 100. In addition, such a setting can make the second prefabricated wall 30 have good anti-scouring performance, and can achieve the reinforcement of the slope foot of the embankment structure 100.

[0062] In some embodiments of the present invention, Figure 4 As shown, along the slope top to the slope bottom direction (i.e. Figure 1 The drainage channel 34 gradually slopes downward. As some embodiments of the present application, the drainage channel 34 has a downward slope of 4%, that is, for every 100 meters of horizontal distance, the drainage channel 34 vertically drops by 4 meters. By making the drainage channel 34 along the direction from the top of the slope to the bottom of the slope (i.e. Figure 1 The X direction shown in the figure gradually inclines downward, which can facilitate the drainage of the second prefabricated wall 30 and enable the second prefabricated wall 30 to have a better drainage effect, which is beneficial to improving the drainage performance of the embankment structure 100.

[0063] In some embodiments of the present invention, Figure 1 As shown, there are multiple drainage mats 50, which are arranged along the height direction of the embankment structure 100 (i.e. Figure 1 In the Z direction shown in the figure), a plurality of drainage pads 50 are arranged in sequence.

[0064] The number of drainage pads 50 may be, but is not limited to, two, three, four, etc. As some embodiments of the present application, the number of drainage pads 50 is three, along the height direction of the embankment structure 100 (i.e. Figure 1 The three drainage pads 50 are arranged in sequence, and the drainage pads 50 are used to guide the water in the embankment body 10 to the slope surface, reduce the water pressure inside the embankment body 10, and reduce the probability of slippage of the embankment structure 100.

[0065] As some embodiments of the present application, the embankment body 10 needs to be filled with soil during the construction process. A layer of drainage mat 50 can be laid after each layer of soil is filled in the embankment body 10. This arrangement can ensure that the moisture in the embankment body 10 is discharged without accumulation, and can keep the inside of the embankment body 10 dry.

[0066] By making the number of the drainage mats 50 multiple and making the multiple drainage mats 50 arranged along the height direction (i.e. Figure 1 The embankment body 10 is arranged in sequence (in the Z direction shown), which can ensure smooth drainage of water from the embankment body 10, reduce the water pressure inside the embankment body 10, reduce the risk of slippage of the embankment body 10, and reduce the probability of soil instability caused by local concentration of moisture in the embankment body 10.

[0067] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the drainage mat 50 includes: a permeable layer 51, a drainage layer 52 and an impermeable layer 53. The drainage layer 52 is located between the permeable layer 51 and the impermeable layer 53 and extends along the height direction of the embankment structure 100 (i.e. Figure 1 The water-permeable layer 51 (in the Z direction shown) is located above the drainage layer 52.

[0068] The drainage layer 52 is located between the permeable layer 51 and the impermeable layer 53, that is, along the height direction of the embankment structure 100 (i.e. Figure 1 In the Z direction shown in the figure, the water-permeable layer 51, the drainage layer 52 and the anti-seepage layer 53 are arranged in sequence, and the water-permeable layer 51 is located above the drainage layer 52.

[0069] The material of the permeable layer 51 may be, but not limited to, polypropylene geotextile, the material of the drainage layer 52 may be, but not limited to, polypropylene drainage core material, and the material of the anti-seepage layer 53 may be, but not limited to, geotextile treated with a hydrophobic polymer. The permeable layer 51 can ensure that water flows smoothly, but fine soil particles can be retained, which can improve the service life of the embankment structure 100. Water flows through the permeable layer 51 and the drainage layer 52 to evenly discharge the embankment body 10 and guide it to the slope surface. The anti-seepage layer 53 can prevent water from flowing through the anti-seepage layer 53, ensuring the centralized stability of drainage flow.

[0070] Such a setting can reduce the probability of soil loss in the embankment structure 100, can increase the service life of the embankment structure 100, and can improve the drainage performance of the embankment structure 100. Moreover, such a setting can enable the drainage pad 50 to take into account the functions of drainage and filtration, which is beneficial to improving the overall stability of the embankment structure 100.

[0071] In some embodiments of the present invention, Figure 1 As shown, the embankment structure 100 further includes: an anti-scour layer 61 and a water-conducting layer 62 . The anti-scour layer 61 is arranged on the slope surface of the embankment body 10 , and the water-conducting layer 62 is arranged on a side of the anti-scour layer 61 away from the slope surface.

[0072] That is to say, the anti-scour layer 61 and the water-conducting layer 62 are both arranged on the slope surface of the embankment body 10 , the anti-scour layer 61 has a side away from the slope surface and a side close to the slope surface, and the water-conducting layer 62 is arranged on the side of the anti-scour layer 61 away from the slope surface.

[0073] The material of the anti-scour layer 61 may be, but is not limited to, geotextile, etc., and the material of the water-conducting layer 62 may be, but is not limited to, polypropylene three-dimensional geomat, etc.

[0074] Such a configuration can improve the anti-scouring performance of the embankment structure 100 , and can enable the embankment structure 100 to quickly conduct water on the slope, which is beneficial to improving the stability of the water conduction of the embankment structure 100 .

[0075] In some embodiments of the present invention, Figure 1 As shown, the geogrid 40 is in contact with the second prefabricated wall 30, that is, along the height direction of the embankment structure 100 (i.e. Figure 1 The geogrid 40 is disposed below the embankment structure 100 , and one end of the geogrid 40 is abuttable against the second prefabricated wall 30 , so that the second prefabricated wall 30 provides support for the geogrid 40 .

[0076] Such an arrangement can provide a fixing point for the geogrid 40 through the second prefabricated wall 30 , thereby increasing the stability of the geogrid 40 , thereby further improving the anti-slip performance and overall stability of the entire embankment structure 100 .
