[0030] The following is combined Figures 1 to 3 This invention describes a dry-laid stone retaining wall structure. The dry-laid stone retaining wall structure includes: a retaining wall mechanism 1, a first soil layer 2, and a mesh mechanism 3. The retaining wall mechanism 1 includes multiple wall bodies 11 arranged in layers according to a specific order to form an integral retaining wall structure. The first soil layer 2 is located on one side of the retaining wall mechanism 1, providing lateral support and stability for the retaining wall. The mesh mechanism 3 includes a first mesh 31 and a second mesh 32. The first end of the first mesh 31 is inserted between two adjacent wall bodies 11, and the second end extends through the retaining wall mechanism 1 into the first soil layer 2. The second mesh 32 is angledly connected to the second end of the corresponding first mesh 31 and inserted into the first soil layer 2. The first mesh 31 and the second mesh 32 play important anchoring and stabilizing roles.
[0031] In this embodiment, the first end of the first mesh 31 is precisely inserted between two adjacent walls 11. This allows the first mesh 31 to penetrate deep into the internal structure of the wall 11, thus forming an effective anchoring effect in the lateral direction. This design not only enhances the connection strength between the walls 11 but also effectively improves the overall retaining wall structure's resistance to shear forces. The second end of the first mesh 31 extends out of the retaining wall mechanism 1 and into the first soil layer 2. This extension is angularly connected to the second mesh 32 at a specific angle. Through this angular connection, the second mesh 32 can further penetrate into the soil layer, forming a mesh-like anchoring system with the first mesh 31 within the first soil layer 2. This mesh structure not only increases the contact area and friction between the retaining wall and the soil layer but also effectively disperses and transfers stress, significantly improving the collaborative working ability between the retaining wall and the first soil layer 2. In practical applications, this collaborative effect can effectively prevent overall instability caused by local slippage, ensuring the safety and stability of the entire retaining wall structure during long-term use.
[0032] The construction sequence for this dry-laid stone retaining wall structure is as follows:
[0033] Earthwork excavation: First, earthwork excavation work is carried out. According to the design requirements for the retaining wall size and location, the corresponding foundation trench is excavated. During excavation, it is necessary to ensure that the bottom surface of the foundation trench is flat and to reserve a certain amount of construction operation space for the subsequent masonry of the retaining wall foundation 12.
[0034] Construction of the dry-laid stone retaining wall foundation 12: Within the excavated foundation trench, begin constructing the bottom wall 11 of the retaining wall structure 1, i.e., the retaining wall foundation 12. The construction of the foundation wall 11 should ensure its flatness and stability, providing solid support for the subsequent construction of the retaining wall. During construction, select stones that meet design requirements; the stones should interlock to minimize gaps.
[0035] Construction of the dry-laid stone retaining wall body: On top of the foundation wall 11, the other walls 11 of the retaining wall mechanism 1 are constructed sequentially to form the retaining wall body. During the construction process, the walls should be laid in layers with staggered joints to ensure the integrity and stability of the wall body 11. Each layer of stones should be placed stably, and the gaps between the stones should be filled with small stones to enhance the tightness of the wall body 11.
[0036] Place the mesh structure 3 at a suitable location on the retaining wall: During the construction of the wall 11, place the mesh structure 3 at a suitable location on the retaining wall according to the design requirements. The first end of the first mesh 31 is inserted between two adjacent walls 11, and the second end protrudes through the retaining wall structure 1.
[0037] The mesh is bent and anchored along the excavation line: After the second end of the first mesh 31 passes through the retaining wall, it is bent and anchored along the excavation line, extending it into the first soil layer 2. At the same time, the second mesh 32 is connected at an angle to the second end of the corresponding first mesh 31 and inserted into the first soil layer 2 to form a mesh anchor.
[0038] Finally, backfilling: After the mesh structure 3 is installed, backfilling is carried out. Backfilling should be done in layers and compacted to ensure the density of the backfill soil, so as to provide sufficient lateral support and prevent deformation of the retaining wall.
[0039] The dry-laid stone retaining wall structure provided by this utility model uses a first mesh 31 inserted in staggered layers between adjacent walls 11 to form a lateral anchoring effect, effectively enhancing the shear resistance of the retaining wall structure and overcoming the defect of traditional dry-laid stone retaining walls that rely solely on gravity for stability. Simultaneously, the second mesh 32 and the first mesh 31 form a mesh-like anchoring system within the first soil layer 2, improving the synergistic effect between the retaining wall and the first soil layer 2 and preventing overall instability caused by localized slippage.
[0040] In some embodiments, such as Figure 3As shown, both the first mesh panel 31 and the second mesh panel 32 include: a frame 33 and a mesh surface 34; the frame 33 is connected end to end, with a notch formed inside, and the mesh surface 34 covers and is fixed within the notch, with the perimeter of the mesh surface 34 connected to the frame 33 within the notch to form a whole. The mesh surface 34 itself is composed of several interwoven wires, forming multiple mesh openings 35. The size and shape of the mesh openings 35 can be adjusted according to actual needs to meet different anchoring and stability requirements. This design not only enhances the structural strength of the mesh panel but also improves the friction and anchoring effect between the mesh panel and the soil layer.
[0041] Specifically, the first mesh panel 31 and the second mesh panel 32 can share the same frame 33 at their connection point. This shared frame 33 design not only simplifies the installation process but also reduces material usage and improves the overall integrity and stability of the structure. Through this design, the first mesh panel 31 and the second mesh panel 32 can work closely together to form a mesh-like anchoring system, further enhancing the synergy between the retaining wall and the first soil layer 2, and effectively preventing overall instability caused by local slippage.
[0042] In some examples, such as Figure 3 As shown, the frames 33 of both the first mesh panel 31 and the second mesh panel 32 are square. Specifically, the frame 33 is formed by connecting several rods end to end to create a square frame. The square frame design gives the mesh panels a regular geometric shape, facilitating precise installation and positioning on the construction site. The four corners of the frame 33 are fixed by welding or bolting to ensure the integrity and stability of the frame 33. The dimensions of the frame 33 are customized according to actual project requirements to adapt to different wall structures 11 and soil conditions. The mesh surface 34 covers and is fixed within the notches inside the frame 33. The mesh surface 34 is formed by interlacing several mesh wires to create multiple evenly distributed mesh openings 35. The size of the mesh openings 35 can be adjusted according to actual needs, typically between a few centimeters and tens of centimeters, to ensure that the mesh surface 34 has sufficient strength and anchoring capacity.
[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple mesh structures 3 are provided, with at least one mesh structure 3 between two adjacent wall sections 11. This ensures that each connection point between wall sections 11 has the anchoring effect of the mesh structure 3, thereby enhancing the lateral connection strength between wall sections 11. By setting at least one mesh structure 3 between each layer of wall sections 11, the stress between the wall section 11 and the soil layer can be effectively dispersed and transferred, preventing cracking or slippage of the wall section 11 due to local stress concentration. Simultaneously, by setting multiple mesh structures 3 between adjacent wall sections 11, a three-dimensional anchoring network can be formed. This network not only enhances the synergy between the retaining wall and the soil layer but also improves the stability and shear resistance of the entire retaining wall structure.
[0044] In this embodiment, the mesh structures 3 arranged between adjacent walls 11 are staggered. The mesh structures 3 are not aligned between adjacent walls 11, but are staggered by a certain distance or angle. This layout ensures the formation of an interwoven anchoring network between the walls 11, thereby more effectively dispersing and transferring stress and enhancing the lateral connection strength between the walls 11. Specifically, the first end of the first mesh 31 of each mesh structure 3 is inserted at different positions between adjacent walls 11, avoiding stress concentration and improving the uniformity and stability of the overall structure.
[0045] It should be noted that multiple mesh structures 3 are provided between two adjacent walls 11, with the mesh structures 3 arranged alternately within the same layer. Specifically, multiple mesh structures 3 are provided between adjacent walls 11, and these mesh structures 3 are arranged alternately within the same layer. This alternating arrangement means that the mesh structures 3 maintain a certain distance from each other, avoiding overly dense or sparse arrangements, thus ensuring that each mesh structure 3 can effectively perform its anchoring and stabilizing function. The distribution of the mesh structures 3 between the walls 11 can be reasonably adjusted according to the length and height of the walls 11 and the properties of the soil layer to achieve the best stabilizing effect.
[0046] The width of the mesh structure 3, along the length of the retaining wall structure 1, is designed to be between 450 mm and 550 mm, preferably 500 mm. This width range ensures that the mesh structure 3 can provide sufficient anchoring force between the walls 11, while facilitating installation and fixing on the construction site. The width of the mesh structure 3 can be adjusted according to actual engineering needs to adapt to different wall 11 structures and soil conditions.
[0047] The spacing between the mesh structures 3 arranged in the same layer is designed to be between 1950 mm and 2050 mm, preferably 2000 mm. This spacing range ensures that the mesh structures 3 can be evenly distributed between the wall 11, forming an effective anchoring network, thereby enhancing the overall stability and shear resistance of the retaining wall. The spacing should be reasonably adjusted according to the length and height of the wall 11 and the properties of the soil layer to achieve the best stability effect.
[0048] Based on the above embodiments, in some embodiments, such as Figure 1 As shown, the dry-laid stone retaining wall structure also includes a second soil layer 4, which is located on the other side of the retaining wall mechanism 1, and the height of the first soil layer 2 is greater than the height of the second soil layer 4.
[0049] Specifically, the first soil layer 2 is located on one side of the retaining wall mechanism 1, while the second soil layer 4 is located on the other side of the retaining wall mechanism 1. The first soil layer 2 is typically located on the soil-facing side of the retaining wall, and its height is relatively high, exerting a greater earth pressure on the retaining wall mechanism 1. The second soil layer 4 is located on the soil-repelling side of the retaining wall, and its height is relatively low, enabling it to support the retaining wall mechanism 1 and further improve the stability of the retaining wall.
[0050] In some embodiments, such as Figure 1 As shown, the first end of the first mesh 31 extends to the outer edge between the two walls 11, forming an exposed portion. This exposed portion can be combined with other structures or materials on the outside of the walls 11 to provide additional support and stability. Thus, the mesh mechanism 3 not only provides anchoring between the walls 11, but also forms additional support and connection on the outside of the walls 11, further enhancing the lateral stability between the walls 11.
[0051] The extension to the outer edge allows the mesh structure 3 to provide anchoring force both between and on the outer side of the walls 11, enhancing the lateral connection strength between the walls 11 and further improving the overall stability of the retaining wall. It can better adapt to complex terrain conditions, such as areas requiring additional support on the outer side of the walls 11, by providing extra stability through the mesh structure 3 extending to the outer edge.
[0052] In some embodiments, such as Figure 1 As shown, the angle θ between the second mesh 32 and the corresponding first mesh 31 is equal to the slope angle of the retaining wall mechanism 1, allowing the mesh mechanism 3 to better adapt to the inclination angle of the retaining wall, thereby enhancing its anchoring effect and stability. This angle setting is beneficial for the second mesh 32 to more effectively disperse and transfer the lateral pressure transmitted from the soil layer to the first mesh 31 and the retaining wall mechanism 1, avoiding stress concentration.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
