DETAILED DESCRIPTION

[0033] The specific embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0034] In the present application, the orientation words such as "up, down, left, right" are generally defined as the direction of the drawing surface, and "inner, outer" refers to the inner and outer contours of the relevant parts. In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] As shown in Figures 1 to 3 The present application provides a filled retaining wall, comprising a plurality of wall bodies 10, a filling structure 20 and a base 30, each wall body 10 comprising a wall body 11, a first mounting portion 12 and a second mounting portion 13, the top of the wall body 11 is provided with the first mounting portion 12, the bottom of the wall body 11 is provided with the second mounting portion 13, the wall body 11 is formed with a filling cavity 14 and a drainage port 15, the drainage port 15 communicates with the filling cavity 14, the filling cavity 14 penetrates the wall body 11 along the height direction of the wall body 11, the filling cavity 14 is used for accommodating the filling structure 20, a plurality of wall bodies 10 are arranged in sequence along the up-down direction, the first mounting portion 12 and the second mounting portion 13 of each adjacent two wall bodies 10 are connected to each other, and the wall body 11 of the wall body 10 at the bottom end of the plurality of wall bodies 10 is used for being mounted on the foundation through the base 30.

[0037] Through the above technical scheme, by setting the first mounting portion 12 and the second mounting portion 13, the plurality of wall bodies 10 can be arranged in sequence along the up-down direction and connected together to form a complete retaining wall. Such modular design, on the one hand, facilitates the transportation and on-site assembly of the wall body 10, which can reduce the construction time of the workers; on the other hand, the height and length of the retaining wall can be flexibly adjusted according to actual needs, which is suitable for different environments. And, by setting the drainage port 15, the free water in the filling structure 20 can be quickly discharged, so as to accelerate the consolidation process of the filling structure 20, and improve the strength performance of the filling structure 20.

[0038] As an embodiment, as shown in Figures 1 to 2 The first mounting portion 12 is configured as a fitting block protruding from the wall body 11, and the second mounting portion 13 is configured as a mounting cavity formed on the wall body 11, one end of the mounting cavity is configured as an open end, and the other end is configured as a closed end, and the fitting block of each adjacent two wall bodies 10 is inserted into the mounting cavity.

[0039] It should be understood that, in the same wall 10, when the fitting block is above the mounting cavity, i.e. the fitting block is at the top of the wall body 11 and the mounting cavity is at the bottom of the wall body 11, the fitting block of the wall 10 can be inserted into the mounting cavity of the wall 10 above, and the mounting cavity of the wall 10 can accommodate the fitting block of the wall 10 below. When the mounting cavity is above the fitting block, i.e. the mounting cavity is at the top of the wall body 11 and the fitting block is at the bottom of the wall body 11, the fitting block of the wall 10 can be inserted into the mounting cavity of the wall 10 below, and the mounting cavity of the wall 10 can accommodate the fitting block of the wall 10 above.

[0040] By setting the fitting block and the mounting cavity, since the fitting block can be directly inserted into the mounting cavity without the need for additional fixing tools or materials (such as bolts, concrete, etc.), the assembly time can be greatly shortened, and the work efficiency can be improved. In addition, the plug-in fit between the fitting block and the mounting cavity can reduce the possibility of misalignment between the walls 10, which is beneficial to improve the aesthetics of the retaining wall. Such design not only simplifies the connection process between the walls 10, but also enables the walls 10 to fit closely.

[0041] In addition, since the filling cavity 14 penetrates the wall body 11 in the height direction of the wall body 11, after the assembly of the multiple walls 10 is completed, the filling cavities 14 on each wall 10 are interconnected and can jointly define a large accommodation cavity. In this way, the workers can fill the filling structure 20 through the accommodation cavity of the retaining wall, and discharge the excess free water through the multiple drainage openings 15 of the retaining wall.

[0042] As an embodiment, as shown in Figures 1 to 2 The filling cavity 14 includes a first filling cavity 141 and two second filling cavities 142, the first filling cavity 141 is arranged at the middle of the wall body 11 and communicates with the drainage opening 15, the two second filling cavities 142 are respectively arranged at the two sides of the first filling cavity 141, the filling structure 20 is arranged in the first filling cavity 141 and the two second filling cavities 142, the first mounting portion 12 is two, and the two first mounting portions 12 are respectively arranged between adjacent first filling cavities 141 and second filling cavities 142, wherein the number of the second mounting portions 13 corresponds to the number of the first mounting portions 12.

[0043] The two second filling cavities 142 are symmetrically arranged with the first filling cavity 141 as the center of symmetry. This arrangement can make the wall body 11 more evenly distribute the load when bearing external pressure, thereby improving the stability and durability of the entire retaining wall structure. Moreover, by reasonably allocating the filling structure 20, the pressure transmission path inside the retaining wall can be optimized, providing more effective surrounding rock support and reducing the impact of ground pressure on the wall 10. In addition, due to the design of the filling cavity 14, the amount of wall 10 material can be reduced, and the total weight of the wall body 11 can be reduced. This not only reduces the cost of raw materials, but also reduces the physical load during transportation and installation, i.e. lighter wall 10 modules are easier to transport and install.

[0044] It should be noted that, as shown in Figures 1 to 2 Since the first filling cavity 141 is larger than the second filling cavity 142, the first filling cavity 141 can be used as a containing space for the filling structure, and the first filling cavity 141 is directly connected to the drainage port 15, so that the free water in the filling material injected into the first filling cavity 141 can be quickly drained, thereby accelerating the consolidation process and improving the strength and stability of the filling body. The two second filling cavities 142 are located on both sides of the first filling cavity 141 and can serve as auxiliary support, helping to enhance the overall structural stability of the wall 10 and its ability to resist ground pressure, while also reducing the weight of the wall body 11 for easier transportation and installation. In addition, the filling structure in the second filling cavity 142 can naturally seep through the interface adjacent to the first filling cavity 141 to the first filling cavity 141, and then be drained through the drainage port 15 of the first filling cavity 141. Therefore, even if the second filling cavity 142 does not have a corresponding drainage port 15, excess moisture can still be effectively drained.

[0045] In order to facilitate hoisting of the wall 10, as an embodiment, as shown in Figures 1 to 2 A lifting hole 16 is formed on the first mounting portion 12, and the lifting hole 16 is located at the top center position of the first mounting portion 12.

[0046] By arranging the lifting hole 16 at the top center position of the first mounting portion 12, the wall body 11 can be kept in a horizontal state during hoisting, avoiding tilting or rotation of the wall body 11, thereby achieving more accurate positioning.

[0047] As an embodiment, the filled retaining wall further comprises an adhesive for filling the gap between the filling structure 20 and the filling cavity 14.

[0048] By using the adhesive, the connection strength between the filling structure 20 and the inner wall of the containing cavity can be improved, so that multiple walls 10 can be effectively connected together, thereby effectively enhancing the structural strength of the entire retaining wall.

[0049] As an implementation form, the adhesive comprises a foaming agent.

[0050] The presence of the foaming agent can make the adhesive expand rapidly after injection, so as to completely fill all possible tiny gaps or irregular surfaces. On the other hand, the adhesive can form a continuous and dense connection layer in a larger range, thereby effectively improving the bonding force between the filling structure 20 and the wall body 11.

[0051] As an implementation form, as shown in Figure 3 The filling structure 20 comprises a filling bag 21 and a filling material 22, and the filling bag 21 has a cavity for accommodating the filling material 22.

[0052] The filling material 22 can be waste produced in the mining process, which can not only reduce the cost of the filling material, but also solve the problem of waste accumulation.

[0053] In order to transport the free water discharged to the designated position, as an implementation form, the filling retaining wall further comprises a drain pipe, and the drain pipe is connected to the drain port 15.

[0054] Through the drain pipe, the free water generated in the filling structure 20 can be guided and discharged, preventing water accumulation from softening or expanding the filling material 22, thereby affecting the overall stability of the retaining wall.

[0055] As an implementation form, as shown in Figure 1 The base 30 comprises a bottom plate 31 and a plurality of connecting pieces 32. The top of the bottom plate 31 is connected to the bottom of the wall body 11 of the wall 10 located at the bottom end of the wall 10, and the bottom of the bottom plate 31 is used to be attached to the foundation. Each connecting piece 32 is configured as an expansion bolt, and a plurality of mounting holes are formed on the bottom plate 31 and are arranged circumferentially along the bottom plate 31. One end of each connecting piece 32 is connected to the outer side of the top of the bottom plate 31, and the other end of each connecting piece 32 is used to pass through the corresponding mounting hole and be inserted into the pre-buried hole on the foundation.

[0056] The bottom plate 31 can serve as a transition layer between the wall 10 and the foundation. It not only provides a direct support surface, but also effectively cooperates with the expansion bolts through its mounting holes, thereby enhancing the integrity and stability of the entire structure.

[0057] The plurality of mounting holes are arranged circumferentially along the bottom plate 31, so that the plurality of expansion bolts can be uniformly distributed on the entire bottom plate 31, and the force transmission is more balanced.

[0058] In other examples, the connecting piece 32 can be an anchor bolt or a chemical anchor.

[0059] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments. Various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0060] In addition, it should be noted that each specific technical feature described in the above-described specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, various possible combinations are not described again in the present application.

[0061] In addition, various different embodiments of the present application can also be combined in any appropriate manner, as long as it does not deviate from the idea of the present application, and it should be considered as disclosed in the present application.
