Description

Technical Field

[0001] This utility model relates to the field of civil engineering protective structure technology, specifically to a gabion retaining wall with a self-locking structure, magnetic assisted fixing and fiber optic monitoring function, which is suitable for river slope protection, mountain reinforcement and other scenarios. Background Technology

[0002] Gabion retaining walls are mesh structures woven from galvanized iron wire or hot-dip galvanized steel wire, filled with stones or other hard materials, used for soil or water retention. They have good permeability, durability, and ecological properties, and are widely used in water conservancy projects, highway and railway protection, slope stabilization, and other fields.

[0003] In traditional gabion retaining wall construction, multiple gabion cages are tied together using binding wire. However, this connection method has several problems. First, construction workers need to thread the binding wire through the mesh and tie adjacent cages together one by one, a tedious and time-consuming process, which significantly extends the construction period, especially in large-scale projects. Second, the stability of the binding wire connection is limited; it is prone to loosening or even falling off when subjected to external impacts or the weight of stones, affecting the overall stability and service life of the retaining wall.

[0004] Furthermore, existing gabion cages are difficult to align with adjacent sides during assembly, resulting in low alignment accuracy. Construction workers need to repeatedly adjust the position of the cages to ensure their flatness and verticality, which not only increases labor intensity but may also lead to inconsistent construction quality. Moreover, traditional gabion retaining walls lack effective monitoring methods, making it impossible to monitor the displacement and stability of the retaining wall in real time and to detect potential safety hazards in a timely manner.

[0005] To address the aforementioned issues, some improvements have been implemented, such as using specialized tools to assist alignment or adding marking lines to the surface of the gabions. However, these methods mostly only improve splicing efficiency and accuracy to a certain extent, failing to fundamentally solve the problem and potentially increasing construction costs or complexity. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a self-locking gabion retaining wall. The self-locking structure enables rapid assembly and alignment of the gabion cages, improving construction efficiency and stability. It includes:

[0007] Multiple stacked gabion mesh cage units, which are spliced ​​together vertically by a self-locking structure;

[0008] The self-locking structure includes complementary grooves and protrusions disposed between adjacent cage units. The grooves and protrusions are configured to automatically align and fit together during splicing, so as to achieve rapid positioning and fixing of adjacent cage units.

[0009] In one embodiment, the cage unit includes a bottom cage, a middle cage, and a top cage;

[0010] The bottom mesh cage and the middle mesh cage are respectively provided with a groove and a corresponding protrusion on their adjacent sides;

[0011] The top mesh cage and the middle mesh cage are respectively provided with a protrusion and a corresponding groove on their adjacent sides;

[0012] Adjacent middle cages are connected by the two protrusions and two grooves fitting together.

[0013] In one embodiment, the contact surfaces of adjacent cage units are fixed with the assistance of magnetic traction components;

[0014] The magnetic attraction component includes a magnetic strip disposed inside the cage unit. The magnetic strip has a magnetic part that passes through the mesh and is used to attract adjacent cage units.

[0015] In one embodiment, the magnetic strip is provided with symmetrical abutment grooves, the openings of which face the inside of the cage unit and are used to abut against the edges of the filling stones; the abutment grooves are provided with a second rope-passing slot for binding wire to pass through and fix the magnetic strip.

[0016] In one embodiment, the magnetic strip is provided with at least one optical fiber groove, the opening of which faces the outside of the cage unit; an optical fiber sensor is arranged in the optical fiber groove, the optical fiber sensor penetrates the top, middle and bottom of the retaining wall and is connected to the monitoring equipment signal.

[0017] In one embodiment, the optical fiber slot is provided with multiple rope-threading slots for binding optical fibers.

[0018] In one embodiment, the top net cage is provided with an ecological net cage, which has planting holes for fixing plants.

[0019] In one implementation, adjacent cage units are reinforced by binding wire.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention utilizes a self-locking structure to facilitate the assembly of gabion mesh cages, reducing construction time and labor intensity. Construction workers can quickly position and fix the cages without repeatedly adjusting their positions, significantly improving construction efficiency and shortening project cycles. Furthermore, adjacent cage units form a stable connection through the interlocking of grooves and protrusions, and the auxiliary fixation of magnetic components.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Taking riverbank protection projects as an example:

[0029] like Figure 1As shown, this utility model provides a self-locking gabion retaining wall, comprising: multiple stacked gabion mesh cage units 1, wherein the mesh cage units 1 are spliced ​​together in the vertical direction by a self-locking structure; the self-locking structure includes complementary grooves and protrusions disposed between adjacent mesh cage units 1, wherein the grooves and protrusions are configured to automatically align and fit together during splicing, so as to achieve rapid positioning and fixing of adjacent mesh cage units 1.

[0030] Traditional gabion baskets are mostly rectangular prisms with regular shapes, which can be stacked like bricks to form a wall during use. This embodiment does not add any additional auxiliary devices to the original gabion baskets. Instead, it uses galvanized iron wire or hot-dip galvanized steel wire to weave or combine the gabion baskets into irregularly shaped structures with grooves and protrusions. The main body of this irregularly shaped structure is still a cuboid, and after two adjacent gabion baskets are longitudinally spliced, the protrusions are inserted into and embedded in the grooves. Therefore, the presence of the grooves and protrusions does not hinder the splicing of gabion baskets, nor does it affect the gaps in the retaining wall formed after the gabion baskets are longitudinally stacked. The gabion baskets can still be spliced ​​into a wall in a manner similar to bricks.

[0031] During use, engineers simply insert the protruding structure on one gabion cage into the groove on another, automatically aligning the two gabion cages. This blind alignment process significantly reduces the time and labor intensity for engineers, improving work efficiency. Furthermore, after insertion, the groove structure, in conjunction with the protruding structure, forms a self-locking structure, restricting the horizontal freedom between two longitudinally adjacent gabion cages and enhancing the structural stability of the retaining wall formed by the splicing of gabion cages.

[0032] Thus, following the above-described insertion method, individual mesh cage units 1 are longitudinally inserted together using a self-locking structure to form a retaining wall. Furthermore, because it is used in riverbank protection projects, it can be... Figure 1 Similarly, multiple retaining walls of varying heights are arranged horizontally, forming a stepped pattern on both sides of the highest retaining wall. This gradually distributes the pressure of the soil or water onto each retaining wall, preventing a single layer of retaining wall from bearing excessive load and thus improving the overall stability of the enclosure structure. Simultaneously, this stepped arrangement increases the contact area between the retaining wall and the soil, thereby enhancing the retaining wall's resistance to sliding.

[0033] Optionally, multiple gabion cages in the same retaining wall can be divided into three categories according to their placement height: bottom cage 10, middle cage 11, and top cage 12. The bottom cage 10 and the middle cage 11 are respectively provided with a groove and a corresponding protrusion on their adjacent sides. The top cage 12 and the middle cage 11 are respectively provided with a protrusion and a corresponding groove on their adjacent sides. Adjacent middle cages 11 are connected by the interlocking of the protrusion and the groove.

[0034] In this context, the bottom gabion 10 and the top gabion 12 refer to the lowest and highest layers of gabion cages in the same retaining wall, respectively, while all gabion cages between the bottom gabion 10 and the top gabion 12 are collectively referred to as the middle gabion 11. For example... Figure 2 As shown, during the retaining wall construction process, the bottom wire mesh cage 10 is first placed horizontally on the pre-prepared foundation pit or base, with the side with the groove facing upwards. Then, the side of the middle wire mesh cage 11 with the protrusion is aligned with the groove, so that the protrusion is inserted into the groove, thus completing the alignment and overlap between the middle wire mesh cage 11 and the bottom wire mesh cage 10. Since the protrusion and groove are opposite to each other on the middle wire mesh cage 11, the groove will naturally face upwards after the protrusion 1 aligns with the groove below. Then, the top wire mesh cage 12 is placed with the side with the protrusion facing downwards until the protrusion is inserted into the groove, thus completing the alignment and fixation between the top wire mesh cage 12 and the middle wire mesh cage 11.

[0035] Furthermore, as is well known, the height of each net cage is limited, and the height of a retaining wall formed by simply building three layers—bottom, middle, and top—is obviously insufficient to meet usage requirements in most cases. The insufficient height of the retaining wall can be compensated for by arranging multiple layers of middle net cages 11. Specifically, multiple layers of middle net cages 11 can be added between the top net cage 12 and the bottom net cage 10. Adjacent middle net cages 11 are stacked one on top of the other by inserting protrusions into grooves, thus forming a retaining wall composed of one bottom net cage 10, several layers of middle net cages 11, and one top net cage 12. The horizontal restraint provided by the protrusions and grooves between the net cages enhances the ease of assembly and the stability during use.

[0036] Furthermore, protrusion one can be placed on the bottom wire mesh box 10, and groove one can be placed on the top wire mesh box 12, while the middle wire mesh box 11 remains unchanged, with protrusion two and groove two still provided on its opposite sides. The specific insertion method, sequence, and principle are exactly the same as in the above embodiment, and the retaining wall can also be built. However, during the splicing process, the middle wire mesh box 11 needs to be rotated one full turn to adapt to the change in the placement position of groove one and protrusion one.

[0037] In another embodiment, a magnetic suction component can be added inside the cage unit 1 so that the contact surfaces of adjacent cage units 1 are fixed with the help of the magnetic suction component; the magnetic suction component includes a magnetic strip 13 disposed inside the cage unit 1, and the magnetic strip 13 is provided with a magnetic part 135 passing through the mesh to attract adjacent cage units 1.

[0038] like Figure 3 As shown, multiple magnetic strips 13 are evenly arranged on the inner wall of the wire mesh unit 1. When the engineers bring the woven wire mesh units 1 close together, the magnetic parts 135 on the magnetic strips 13 that pass through the mesh openings of the wire mesh unit 1 will attract the corresponding magnetic parts 135 on the wire mesh body woven from galvanized iron wire or hot-dip galvanized steel wire, or on another wire mesh unit 1. This attraction further strengthens the connection between adjacent wire mesh units 1. Furthermore, as the magnetic strips 13 are arranged further, they can also attract horizontally arranged wire mesh units 1, thus ensuring that... Figure 1 After the multi-faceted retaining wall is constructed horizontally, its overall integrity is greatly enhanced, further strengthening its stability when used on one side or in combination with multiple sides. Furthermore, there is no need to worry about the presence of the magnetic portion 135 on the magnetic strip 13 affecting the tightness of the splicing between the wire mesh cage units 1. Specifically, by limiting its thickness to be consistent with the depth of the mesh openings in the wire mesh cage unit 1, the magnetic portion 135 can avoid affecting the joint of the wire mesh cage unit 1 while simultaneously enhancing the splicing stability of the wire mesh cage unit 1. The magnetic portion 135 can specifically be an AlNiCo magnet.

[0039] Furthermore, in order to ensure the installation stability of the magnetic strip 13 on the cage unit 1, abutment grooves 132 can be symmetrically provided on the magnetic strip 13. The opening of the abutment groove 132 faces the inside of the cage unit 1 and is used to abut against the edges of the filling stones. The abutment groove 132 is provided with a rope-passing slot 134 for binding wire to pass through to fix the magnetic strip 13.

[0040] like Figure 4As shown, the opening of the abutment groove 132 faces the inside of the gabion unit 1, and the groove wall of the abutment groove 132 is tightly fitted to the side wall of the gabion unit 1. Multiple rope-threading slots 134 are evenly distributed on the groove wall of the abutment groove 132 that fits against the side wall of the gabion unit 1. Engineers can thread the two ends of the binding wire through two adjacent rope-threading slots 134 until they pass through the mesh of the gabion unit 1, and then close and tighten the two ends of the binding wire until the magnetic strip 13 is firmly fixed to the side wall of the gabion unit 1. In this way, even if the gabion unit 1 is not yet filled with stones, the magnetic strip 13 can remain in its position within the gabion unit 1 and will not easily shift. This ensures that the magnetic strip 13 can function properly after the gabion unit 1 is assembled, thereby enhancing the stability of the assembled gabion unit 1.

[0041] After the stones are filled into the cage unit 1, the scattered stones will automatically fill the abutment groove 132. While filling the abutment groove 132, the entire abutment groove 132 will be pressed against the side wall of the cage unit 1 to further enhance the installation stability of the magnetic strip 13 and prevent the magnetic strip 13 from shifting during the later shaping process of the cage unit 1.

[0042] In another embodiment, to monitor the stability and status of the retaining wall during long-term use in real time, at least one optical fiber groove 131 can be provided on the magnetic strip 13, with the opening of the optical fiber groove 131 facing outwards from the cage unit 1; an optical fiber sensor is arranged inside the optical fiber groove 131, the optical fiber sensor penetrating the top, middle, and bottom of the retaining wall and connected to the monitoring equipment signal. Figure 3 and Figure 4 As shown, the entire fiber optic trough 131 is formed by the magnetic strip 13 and the side wall of the cage unit 1. The magnetic strip 13 completely blocks the stones inside the cage unit 1 from the outside of the fiber optic trough 131, preventing the optical fibers inside the fiber optic trough 131 from being squeezed by the stones and failing.

[0043] To ensure the stability of the optical fiber within the fiber optic slot 131, multiple lanyard slots 133 can be created on one side of the magnetic strip 13, which serves as the wall of the fiber optic slot 131. This allows the optical fiber placed within the slot 131 to be secured to the wall of the slot 131 using straps or binding wires. In this way, the entire optical fiber, through the fiber optic slot 131, forms a relatively fixed unit with the mesh cage unit 1. Consequently, when the mesh cage unit 1 shifts or moves, the optical fiber can immediately detect it, improving the sensitivity and accuracy of the optical fiber sensor.

[0044] Specifically, engineers can, for example, Figure 1Three fiber optic placement points 3 are selected at the top, middle, and bottom of the stepped retaining wall assembly shown. Of course, the selection of fiber optic placement points 3 can be more dense and flexible; this embodiment only uses three fiber optic placement points 3 as an example. Then, the three optical fibers can be laid horizontally across all the fiber optic slots 131 corresponding to the retaining wall layers where the three fiber optic placement points 3 are located, parallel to the ground, thereby completing the fiber optic placement.

[0045] Alternatively, engineers can also rotate the fiber optic cable tray 131 90° in the arrangement direction of the mesh cabinet unit 1, and use a single optical fiber along... Figure 1 The cross-sectional profile of the stepped retaining wall group shown in the figure sequentially connects the three fiber optic placement points 3, and this arrangement is replicated in multiple arrays along the length of the river or retaining wall group, thus completing another arrangement of the fiber optics.

[0046] The optical fibers deployed in the optical fiber channel 131 serve as part of the optical fiber sensor, enabling continuous monitoring of the entire displacement of the stepped retaining wall group. This facilitates real-time monitoring of slope stability and improves the timeliness and accuracy of landslide risk warnings.

[0047] The fiber optic sensor (not shown in the figure) is existing technology. The light source is fed into a modulator via an optical fiber, interacting with the measured parameter outside the modulator, causing a change in the optical properties of the light, resulting in a modulated optical signal. This signal is then fed into a photoelectric device via another optical fiber, and after demodulation, the measured parameter is obtained, enabling the monitoring of relevant data. The principle and specific structure of the fiber optic sensor are existing technologies and will not be elaborated upon here. Specifically, in practical applications, the fiber optic monitoring system can also be powered by solar panels to meet the power supply needs of the monitoring equipment, reduce cable laying costs, and improve system flexibility.

[0048] Furthermore, an ecological net cage 2 can be installed on the top net cage 12 at the very top of the completed retaining wall assembly. The ecological net cage 2 has planting holes for fixing plants. This allows for the construction of an artificial ecosystem on the water surface using the ecological net cage 2. Through the interaction of plants, microorganisms, and water, water quality can be improved, the ecosystem restored, and landscape value provided.

[0049] Furthermore, in order to further enhance the integrity and stability of the retaining wall or retaining wall group, adjacent cage units 1 can be tied together by binding wire on the basis of the above-mentioned self-locking structure splicing and / or magnetic strip 13 adsorption, so as to meet the high stability requirements of the retaining wall.

[0050] Through the above implementation methods, the self-locking gabion retaining wall of this utility model can achieve rapid splicing, stable connection and real-time monitoring, effectively solving the problems existing in the construction of traditional gabion retaining walls, and has high practical value and promotion prospects.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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.
