Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, and in particular to a slope reinforcement device based on geotechnical engineering. Background Technology

[0002] If the foundation pit is deep, the slope needs to be reinforced during the excavation process to prevent it from collapsing. When reinforcing the slope, it is necessary to combine knowledge of geotechnical engineering and determine the specific support method based on the environment of the foundation pit. When using soil nailing wall support, a layer of soil needs to be excavated first to facilitate the support layer. During the support, a layer of concrete needs to be initially sprayed to achieve initial stability of the slope. Then, a layer of steel mesh is laid on the bottom layer of concrete. Then, a drilling rig is used to drill downward-sloping holes on the slope, and soil nails are inserted into the holes. The soil nails are then fixed in the holes by grouting. Then, multiple soil nails are connected together with long steel bars to form a whole. Finally, a layer of concrete is sprayed again, and the above excavation and support procedures are repeated until the foundation pit is excavated to the design depth. The upper and lower support layers are connected by concrete to form a complete foundation pit slope support system.

[0003] When supporting the slope of a foundation pit with soil nailing walls, it is common to excavate a layer of soil to facilitate the support of that layer. However, the upper and lower support structures are connected by concrete, and the bonding strength between the upper and lower layers depends on the quality of the interface treatment. If the roughening is not thorough or the curing is insufficient, the interlayer shear force is likely to exceed the bonding strength, and there is a significant risk of cracking at the connection between the upper and lower layers of the foundation pit support structure. Therefore, this application provides a slope reinforcement device based on geotechnical engineering to meet the requirements. Summary of the Invention

[0004] This invention provides a slope reinforcement device based on geotechnical engineering to solve the problem of a large risk of cracking at the connection between the upper and lower layers of the foundation pit support structure.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A slope reinforcement device based on geotechnical engineering includes two bottom strips, and further includes:

[0007] The connecting mechanism includes a vertical strip fixed between two bottom strips, a square strip fixed to the side of the vertical strip, multiple through slots on the top of the square strip, a sealing component at the bottom of the square strip corresponding to one of the through slots, a positioning component fixed to the side of the vertical strip away from the square strip, multiple T-shaped plates fixed to the top of the square strip, the side of the T-shaped plates being fixedly connected to the side of the vertical strip, and a row of protrusions integrally formed on the side of the bottom strip, with the square strip located between two rows of protrusions.

[0008] When spraying the upper layer of concrete, the sealing component is horizontal and attached to the bottom of the square strip. When spraying the lower layer of concrete, the sealing component is vertical. During transportation, the square strip is stuck in the positioning component.

[0009] Preferably, multiple grooves are provided on opposite sides of the square strip, and the inner walls of the grooves are arc-shaped.

[0010] Preferably, the top of the square strip has multiple sets of through slots II, each set of through slots II has two slots, through slot I is located between two adjacent sets of through slots II, and a square box is fixed at the bottom of the square strip corresponding to the through slot II.

[0011] Preferably, the sealing assembly includes a connecting seat fixed to the bottom of the square strip, an L-shaped plate rotatably connected inside the connecting seat, and when the upper layer of concrete is sprayed, the top of the horizontal part of the L-shaped plate fits against the bottom of the square strip to seal one of the through grooves. A snap-fit ​​component is rotatably connected to the side of the square box, a slot is provided on the vertical part of the L-shaped plate, the snap-fit ​​component is snapped into the slot, a lever is fixed on the side of the vertical part of the L-shaped plate, and a notch is provided at the bottom of the square box.

[0012] Preferably, the thickness of the vertical portion of the L-shaped plate gradually increases from top to bottom.

[0013] Preferably, the snap-fit ​​component includes a snap-fit ​​block, which is rotatably connected to the side of the square box, snaps into a snap-fit ​​slot, and has a handle fixed to its end.

[0014] Preferably, an inclined plate is fixed to the bottom of the horizontal part of the L-shaped plate, and multiple square grooves are opened on the inclined plate. A connecting rod is fixed to the side of the inclined plate, and the end of the connecting rod away from the inclined plate is fixedly connected to the side of the vertical part of the L-shaped plate.

[0015] Preferably, the top of the horizontal portion of the L-shaped plate is provided with multiple strip grooves, which are located within the through groove. The bottom of the inner wall of the strip groove is provided with a downwardly curved surface, and multiple protrusions are fixed on the curved surface.

[0016] Preferably, a limiting plate is fixed to the side of the connecting seat. When the lower layer of concrete is sprayed, the locking block separates from the locking groove, and the L-shaped plate is attached to the side of the limiting plate.

[0017] Preferably, the positioning component includes a rod and a plate fixed to the side of the vertical bar away from the square bar. A rib is fixed to the top of the plate. Both the plate and the rib have inclined surfaces on the side away from the vertical bar. During transportation, the rod is locked at the top of the square bar, and the rib is locked at the bottom of the square bar.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting up a bottom strip, square strip, T-shaped plate, and sealing component, a receiving groove is excavated on the slope of the foundation pit to accommodate the bottom strip. When spraying the upper layer of concrete, the sealing component is horizontally attached to the bottom of the square strip to seal the through groove one, preventing concrete from entering the bottom of the square strip during the spraying of the upper layer of concrete. The T-shaped plate improves the connection strength between the upper layer of concrete and the square strip. When spraying the lower layer of concrete, the sealing component is opened to make it vertical, and the upper and lower layers of concrete are connected at one point in the through groove. At the same time, the vertical sealing component improves the connection strength between the lower layer of concrete and the square strip. The cooperation of the square strip, T-shaped plate, and sealing component greatly improves the connection strength between the upper and lower layers of concrete and reduces the probability of cracking. At the same time, after the initial spraying of concrete for the upper support structure is completed, the through groove one is not completely covered. The through groove one is used to locate the vertical reinforcement of the steel mesh, which facilitates the construction of the steel mesh.

[0020] By setting up protrusions, the connection strength between the bottom strip and the initial shotcrete layer is increased, thereby further improving the connection strength between the upper and lower concrete layers.

[0021] By setting grooves, the contact area between the upper and lower layers of concrete and the square strip is increased, the connection strength between the concrete and the square strip is improved, and the connection strength between the upper and lower layers of concrete is further improved, thereby increasing the reinforcement strength of the foundation pit slope.

[0022] By setting up the through-slot and the square box, when spraying the upper layer of concrete, the concrete can enter the square box through the through-slot and when spraying the lower layer of concrete, the concrete can cover the bottom of the square strip and the outer wall of the square box. The through-slot and the square groove make the square strip uneven, which further increases the connection strength between the upper and lower layers of concrete and the square strip, and further reduces the probability of cracking at the connection between the upper and lower layers of concrete.

[0023] By setting up an L-shaped plate and a snap-fit ​​connector, when spraying the upper layer of concrete, the L-shaped plate adheres to the bottom of the square strip to seal the through groove 1. The snap-fit ​​connector's snap block is locked in the slot to prevent the L-shaped plate from rotating freely, ensuring that the L-shaped plate stably seals the through groove 1. When spraying the lower layer of concrete, the snap block is rotated out of the slot, and then the L-shaped plate can be opened to make it vertical. The L-shaped structure improves the connection strength between the lower layer of concrete and the square strip, thereby ensuring the connection quality between the upper and lower layers of concrete.

[0024] By setting a lever and a notch, the L-shaped panel can be flipped downwards and opened by holding the lever. The lever provides a stable force point for opening the L-shaped panel, while the notch is opened at the bottom of the box to increase the operating space for opening the L-shaped panel, making it easier for construction workers to operate. When the L-shaped panel is strongly connected to the upper concrete layer and cannot be opened by hand, a crowbar or other tools can be inserted into the notch to pry the lever and open the L-shaped panel. The notch provides sufficient space for the operation of crowbars and other tools, thus ensuring that the L-shaped panel can be opened stably under different working conditions.

[0025] By setting up strip grooves and curved surfaces, when spraying the upper layer of concrete, the concrete enters the strip groove from the through groove. The strip groove creates an uneven shape at the bottom of the upper layer of concrete, laying the foundation for improving the connection strength between the upper and lower layers of concrete. At the same time, the bottom of the inner wall of the strip groove has a curved surface, which increases the height of the bottom of the upper layer of concrete, further improving the connection strength between the upper and lower layers of concrete, thereby greatly reducing the probability of cracking between the upper and lower layers of concrete.

[0026] By setting protrusions and fixing them to the curved surface, the bottom of the upper concrete layer is made uneven at the corresponding position on the curved surface, thereby increasing the contact area between the upper and lower concrete layers, improving the connection strength between them, and effectively preventing cracking between the upper and lower concrete layers.

[0027] By setting inclined plates and connecting rods, when the L-shaped plate is in a vertical state, the inclined plates increase the contact area between the lower layer of concrete and the L-shaped plate, thereby increasing the connection strength between the lower layer of concrete and the L-shaped plate, and thus increasing the connection strength between the lower layer of concrete and the square strip. The connecting rods connect the vertical part of the L-shaped plate to the inclined plates, ensuring the structural strength of the vertical part of the L-shaped plate and preventing deformation of the vertical part of the L-shaped plate due to the slots.

[0028] By setting up insert rods, insert plates, and ribs, when the bottom strip is placed into the receiving trench excavated on the slope of the foundation pit, the insert rods, insert plates, and ribs are inserted into the soil of the slope to achieve positioning of the bottom strip, increase the connection strength between the bottom strip and the slope, and ensure that the bottom strip can stably perform its function. At the same time, during transportation, adjacent reinforcement devices can be stacked. At this time, the insert rods and ribs on other reinforcement devices can be respectively locked on the top and bottom of the top strip of the reinforcement device to protect the strip and prevent it from deforming under stress.

[0037] As shown in the figure, specific structures and devices are labeled in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0038] The following is a detailed description of a slope reinforcement device based on geotechnical engineering provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some well-known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0039] like Figures 1-7 As shown, an embodiment of the present invention provides a slope reinforcement device based on geotechnical engineering, including a bottom strip 1, the number of bottom strips 1 being two, and further including:

[0040] The connecting mechanism 2 includes a vertical strip 4 fixed between two bottom strips 1. A square strip 5 is fixed to the side of the vertical strip 4. Multiple through slots 6 are opened on the top of the square strip 5. A sealing component 8 is set at the bottom of the square strip 5 corresponding to the through slots 6. A positioning component 26 is fixed on the side of the vertical strip 4 away from the square strip 5. Multiple T-shaped plates 24 are fixed to the top of the square strip 5. Hollow slots are opened on the T-shaped plates 24 to improve the connection strength between the T-shaped plates 24 and the upper concrete. The side of the T-shaped plates 24 is fixedly connected to the side of the vertical strip 4. A row of protrusions 3 is integrally formed on the side of the bottom strip 1. The square strip 5 is located between two rows of protrusions 3.

[0041] When the upper layer of concrete is sprayed, the sealing component 8 is horizontal and adheres to the bottom of the square strip 5. When the lower layer of concrete is sprayed, the sealing component 8 is vertical. During transportation, the square strip 5 is secured within the positioning component 26. The above structures together form the slope reinforcement device. The two bottom strips 1, together with the vertical strip 4, form the main frame of the reinforcement device. The protrusions 3 on the sides of the bottom strips 1 increase the contact area and interlocking force with the initial sprayed concrete layer, improving the connection strength between the bottom strips 1 and the initial sprayed concrete layer. As the core component connecting the upper and lower layers of concrete, the T-shaped plate 24 at the top of the square strip 5 significantly improves the connection strength with the upper layer of concrete. The through-slot 6 provides a channel for direct connection between the upper and lower concrete layers during spraying of the lower layer, enhancing the overall integrity of the connection. The sealing component 8 seals the through-slot 6 during spraying of the upper layer of concrete, preventing concrete slurry from seeping into the bottom of the square strip 5 and affecting subsequent connections. When spraying the lower layer of concrete, the sealing component 8 opens vertically and embeds into the lower layer of concrete, further improving the connection strength and effectively reducing the probability of cracking at the connection between the upper and lower concrete layers. The positioning component 26 is inserted into the slope soil during use to position the bottom strip 1 and protects the square strip 5 from compression and deformation during transportation, ensuring the subsequent performance of the reinforcement device.

[0042] like Figure 2 and Figure 4 As shown in this embodiment, multiple grooves 22 are provided on the opposite sides of the square strip 5. The inner wall of the groove 22 is arc-shaped. The arc-shaped groove 22 is filled with concrete slurry during shotcreting, which increases the contact area and interlocking degree between the concrete and the square strip 5, and improves the connection strength.

[0043] like Figure 2 and Figure 4 As shown in this embodiment, the top of the square strip 5 has multiple sets of through grooves 7, with two through grooves 7 in each set. Through groove 6 is located between two adjacent sets of through grooves 7. A square box 20 is fixed at the bottom of the square strip 5 corresponding to the through groove 7. The through groove 7 allows the upper layer of concrete slurry to enter the square box 20 smoothly. When the lower layer of concrete is sprayed, the concrete covers the bottom of the square strip 5 and the outer wall of the square box 20. The square box 20 forms an uneven structure at the connection between the upper and lower layers of concrete, which greatly increases the connection area and the interlocking force, and further reduces the probability of cracking.

[0044] like Figure 4 and Figure 5As shown, in this embodiment, the sealing component 8 includes a connecting seat 9 fixed to the bottom of the square strip 5. An L-shaped plate 11 is rotatably connected inside the connecting seat 9, and a round shaft is fixed inside the connecting seat 9. The L-shaped plate 11 achieves rotatable connection with the connecting seat 9 through the round shaft. When spraying the upper layer of concrete, the top of the horizontal part of the L-shaped plate 11 adheres to the bottom of the square strip 5 to achieve sealing at the through groove 6. A snap-fit ​​piece 16 is rotatably connected to the side of the square box 20. A slot 19 is opened on the vertical part of the L-shaped plate 11, and the snap-fit ​​piece 16 is snapped into the slot 19. A lever 15 is fixed to the side of the vertical part of the L-shaped plate 11. A bottom opening of the square box 20 is... With notch 21, the connecting seat 9 allows the L-shaped plate 11 to rotate flexibly. When spraying the upper layer of concrete, the L-shaped plate 11 horizontally blocks the through groove 6 to prevent concrete slurry from seeping into the bottom of the square strip 5. The snap-fit ​​piece 16 and the snap-fit ​​groove 19 cooperate to lock the position of the L-shaped plate 11, preventing the L-shaped plate 11 from rotating due to the impact of concrete and ensuring the stability of the blockage. When spraying the lower layer of concrete, the L-shaped plate 11 is rotated to a vertical position by the lever 15. Notch 21 provides sufficient space for the operation of rotating the L-shaped plate 11, making it easy for construction personnel to open the L-shaped plate 11 and ensure that the through groove 6 is completely open, so as to achieve direct connection between the upper and lower layers of concrete.

[0045] like Figure 5 As shown in this embodiment, the thickness of the vertical part of the L-shaped plate 11 gradually increases from top to bottom. The gradual thickness design of the vertical part enhances the structural strength of the L-shaped plate 11 and prevents the vertical part of the L-shaped plate 11 from deforming under stress.

[0046] like Figure 4 and Figure 5 As shown in this embodiment, the snap-fit ​​component 16 includes a snap-fit ​​block 17, which is rotatably connected to the side of the square box 20. The snap-fit ​​block 17 is snapped into the slot 19, and a handle 18 is fixed to the end of the snap-fit ​​block 17. The snap-fit ​​block 17 is rotatably connected to the side of the square box 20 through a rotating shaft. The snap-fit ​​block 17 rotates around the rotating shaft. The snap-fit ​​block 17 and the slot 19 can be quickly snapped or separated through the handle 18. The operation is convenient. When snapped, the L-shaped plate 11 is locked in a horizontal state. When separated, the L-shaped plate 11 is easily opened. At the same time, when the L-shaped plate 11 is rotated to a vertical state, the snap-fit ​​block 17 can be rotated in the opposite direction so that the end of the handle 18 abuts against the side of the L-shaped plate 11 to prevent the L-shaped plate 11 from rotating at will and to ensure that the L-shaped plate 11 does not rotate when spraying the lower layer of concrete.

[0047] like Figure 5As shown in this embodiment, an inclined plate 23 is fixed to the bottom of the horizontal part of the L-shaped plate 11. Multiple square grooves are provided on the inclined plate 23. A connecting rod 25 is fixed to the side of the inclined plate 23. The end of the connecting rod 25 away from the inclined plate 23 is fixedly connected to the side of the vertical part of the L-shaped plate 11. When the L-shaped plate 11 is vertical, the inclined plate 23 is embedded in the lower layer of concrete, increasing the contact area and connection strength between the concrete and the L-shaped plate 11. The square grooves further increase the interlocking degree between the concrete and the inclined plate 23, improving the connection stability. The connecting rod 25 connects the vertical part of the L-shaped plate 11 to the inclined plate 23, ensuring the structural strength of the vertical part of the L-shaped plate 11 and preventing the vertical part of the L-shaped plate 11 from deforming due to the opening of the slot 19.

[0048] like Figure 6 As shown in this embodiment, the top of the horizontal portion of the L-shaped plate 11 is provided with multiple strip grooves 12, which are located within the through groove 6. The bottom of the inner wall of the strip groove 12 is provided with a downwardly curved surface 13, on which multiple protrusions 14 are fixed. When the upper layer of concrete is sprayed, some of the concrete slurry enters the strip groove 12 through the through groove 6. The curved surface 13 and the protrusions 14 form an irregular concave-convex structure at the bottom of the upper layer of concrete, providing a mechanical interlocking foundation for subsequent connection with the lower layer of concrete, greatly increasing the connection area and strength, and effectively preventing cracking of the upper and lower layers of concrete. At the same time, after the L-shaped plate 11 is rotated to a vertical position, the strip grooves 12 and the protrusions 14 are used to increase the contact area between the lower layer of concrete and the L-shaped plate 11, thereby improving the connection strength between the lower layer of concrete and the L-shaped plate 11.

[0049] like Figure 5 As shown in this embodiment, a limiting plate 10 is fixed to the side of the connecting seat 9. When spraying the lower layer of concrete, the locking block 17 separates from the locking groove 19, and the L-shaped plate 11 is attached to the side of the limiting plate 10. The limiting plate 10 restricts the rotation angle of the L-shaped plate 11, so that it remains vertical when spraying the lower layer of concrete, ensuring that the through groove 6 is completely open.

[0050] like Figure 7 As shown in this embodiment, the positioning component 26 includes an insertion rod 27 and an insertion plate 28 fixed to the side of the vertical bar 4 away from the square bar 5. A rib plate 29 is fixed to the top of the insertion plate 28. Both the insertion plate 28 and the rib plate 29 have inclined surfaces on the side away from the vertical bar 4. During transportation, the insertion rod 27 is stuck at the top of the square bar 5, and the rib plate 29 is stuck at the bottom of the square bar 5. A receiving groove is excavated on the slope to accommodate the bottom bar 1. The insertion rod 27, the insertion plate 28, and the rib plate 29 are inserted into the slope soil to achieve stable positioning of the bottom bar 1 in the receiving groove. The inclined surface design reduces the insertion resistance and improves the convenience of positioning operation. The rib plate 29 enhances the deformation resistance of the insertion plate 28 and ensures the positioning stability. During transportation, the insertion rod 27 and the rib plate 29 are stuck at the top and bottom of the square bar 5 of the adjacent reinforcement device to form a limiting protection and prevent the square bar 5 from being squeezed and deformed.

[0051] Working principle: A receiving groove adapted to the bottom strip 1 is excavated on the slope of the foundation pit. Two bottom strips 1 are placed into the receiving groove at the same time. During the placement process, the insert rod 27 and the insert plate 28 are inserted into the slope soil. The rib plate 29 on the top of the insert plate 28 improves the deformation resistance of the insert plate 28, thereby realizing the stable positioning of the bottom strip 1 in the receiving groove. The inclined design of the insert plate 28 and the rib plate 29 on the side away from the vertical strip 4 reduces the resistance when inserting into the soil, making the positioning operation of the bottom strip 1 more convenient.

[0052] When the upper layer of concrete is sprayed, the L-shaped plate 11 fits tightly against the bottom of the square strip 5 to seal the through groove 6, preventing concrete slurry from seeping into the bottom of the square strip 5 and affecting the connection between the upper and lower layers of concrete. When the L-shaped plate 11 fits tightly against the bottom of the square strip 5, the locking block 17 is locked in the locking groove 19, locking the L-shaped plate 11 in a horizontal sealing state to prevent it from deflecting due to the impact of concrete and to ensure the stability of the sealing.

[0053] When the upper layer of concrete is sprayed, the concrete slurry will cover the upper structure of the bottom strip 1, vertical strip 4 and square strip 5. The protrusion 3 on the side of the bottom strip 1 increases the contact area and interlocking force between the bottom strip 1 and the initial sprayed concrete layer, thereby improving the connection strength between the two. The multiple sets of through grooves 7 on the top of the square strip 5 allow the concrete slurry to enter the square box 20 smoothly. At the same time, some of the concrete slurry enters the strip groove 12 on the top of the L-shaped plate 11 through through groove 6. The curved surface 13 and the protrusion 14 at the bottom of the inner wall of the strip groove 12 form an irregular concave-convex structure at the bottom of the upper layer of concrete, laying the foundation for the subsequent connection with the lower layer of concrete.

[0054] In addition, the T-shaped plate 24 at the top of the square bar 5 is located in the upper layer of concrete, which greatly improves the connection strength between the upper layer of concrete and the square bar 5. When the initial shotcrete is carried out in the upper support structure, the through groove 6 is not completely covered by the concrete. After the initial shotcrete is completed, the positioning function of the through groove 6 can be used to assist in the positioning of the vertical steel bars on the steel mesh, reduce the construction difficulty of the steel mesh, and improve the construction efficiency.

[0055] When spraying the lower layer of concrete, first unlock the L-shaped plate 11 of the sealing component 8, turn the handle 18 to make the locking block 17 rotate and separate from the locking groove 19, and release the lock on the L-shaped plate 11. Then, hold the position of the lever 15 and rotate the L-shaped plate 11 downward to open it. The notch 21 provides sufficient space for the flipping operation. If the L-shaped plate 11 cannot be flipped directly by hand because it is stuck to the upper layer of concrete, tools such as pry bars can be inserted into the lever 15 through the notch 21 and pry the lever 15 to ensure that the L-shaped plate 11 is opened stably. When the L-shaped plate 11 is attached to the limiting plate 10 on the side of the connecting seat 9, the L-shaped plate 11 is in a vertical state. At this time, the through groove 6 is fully open. After the L-shaped plate 11 is rotated to the vertical state, the locking block 17 can be rotated in the opposite direction so that the end of the handle 18 abuts against the side of the L-shaped plate 11 to prevent the L-shaped plate 11 from rotating at will and ensure that the L-shaped plate 11 does not rotate when spraying the lower layer of concrete.

[0056] When the lower layer of concrete is sprayed, the concrete slurry will cover the bottom of the square strip 5, the L-shaped plate 11, and the outer wall of the square box 20. The upper and lower layers of concrete are directly connected through the through groove 6. The inclined plate 23 on the L-shaped plate 11 will be embedded in the lower layer of concrete, which will greatly increase the connection strength between the lower layer of concrete and the square strip 5. At the same time, the square box 20 will make the connection between the upper and lower layers of concrete uneven, thereby increasing the connection strength between the upper and lower layers of concrete. In addition, the notch 21 on the square box 20 can increase the contact area between the lower layer of concrete and the square box 20, improve the connection strength between the lower layer of concrete and the square strip 5, and further improve the connection strength between the upper and lower layers of concrete, preventing cracking at the connection between the two.

[0057] Concrete will also be filled into the grooves 22 on both sides of the square strip 5 to further increase the contact area between the concrete and the square strip 5, improve the connection strength between the concrete and the square strip 5, and thus improve the reinforcement strength of the foundation pit slope.

[0058] During equipment transportation, adjacent reinforcement devices can be stacked to save transportation space. The insertion rod 27 of one reinforcement device is clamped on the top of the square strip 5 of another reinforcement device, and the rib plate 29 is clamped on the bottom of the square strip 5. The insertion rod 27 and the rib plate 29 form upper and lower limit protection for the square strip 5 to prevent the square strip 5 from being squeezed and deformed during transportation, ensuring that the square strip 5 can stably perform its function in subsequent use. At the same time, the insertion plate 28 is clamped between two adjacent square boxes 20 to prevent the reinforcement device from moving in its longitudinal direction.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
