Description

Technical Field

[0001] This utility model belongs to the field of embankment engineering technology, and more specifically, it relates to a graded combined retaining device for embankment slope. Background Technology

[0002] In embankment engineering, slope stability is crucial, directly affecting the overall quality and safety of the project. Existing embankment slope support devices are mostly either monolithic or modular. Monolithic structures are often cast from concrete blocks, forming a complete unit that provides comprehensive slope support. Modular frame structures primarily consist of horizontal and vertical beams, connected by bolts, pins, and other fasteners to form a complete support surface, effectively protecting the slope.

[0003] Existing application number CN202323222859.0 discloses a roadbed slope retaining structure. The retaining frame is internally fitted with wire mesh, and positioning piles are installed at each of the four corners of the retaining frame. Reinforcing components are installed within the positioning piles to enhance the stability of the retaining frame. This invention, through the reinforcement components, can reinforce the positioning piles when inserted into the roadbed slope, increasing the stability of the retaining frame on the roadbed slope and reducing the possibility of the retaining frame detaching from the roadbed slope. The transmission rod within the reinforcement components allows the reinforcement rod to be driven by an external drive device to drill into the outside of the positioning pile. This enables the reinforcement rod to penetrate into harder soil or rock layers, reducing the resistance to its entry into the soil or rock.

[0004] Based on the above, existing embankment slope support devices, especially integral structures, are bulky and easily subject to space constraints during transportation, resulting in poor convenience. Furthermore, the installation phase requires the assistance of large hoisting machinery, which not only increases equipment investment costs but also makes the hoisting, positioning, and debugging processes quite cumbersome. While modular structures offer greater flexibility in transportation, they require a large number of connectors for splicing and assembling to ensure the stability of the connection nodes. This process necessitates significant manpower for point-by-point assembly and tightening, which not only extends the construction period but also involves repetitive and complex manual operations. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a graded combined retaining device for embankment slopes. This addresses the shortcomings of existing embankment slope retaining devices. The integral structure is bulky, easily constrained by space during transportation, and lacks convenience. Furthermore, installation requires large hoisting machinery, increasing equipment costs and making hoisting, positioning, and debugging processes cumbersome. While the modular structure offers greater transportation flexibility, ensuring the stability of connection nodes requires numerous connectors for assembly. This necessitates significant manpower for point-by-point assembly and tightening, extending the construction period and exposing the problems of repetitive and complex manual operations.

[0006] The purpose and effectiveness of this utility model's graded combined retaining device for embankment slopes are achieved through the following specific technical means:

[0007] A graded combined retaining device for embankment slopes includes a retaining body, retaining connecting beams, cross connecting blocks, graded connecting seats, fixed anchors, a combination assembly, and a limiting assembly. Multiple sets of retaining connecting beams are arranged longitudinally and transversely within the retaining body. Multiple sets of cross connecting blocks are also arranged within the retaining body. The graded connecting seats are located at the lower part of the retaining body. Multiple sets of fixed anchors are inserted into the middle of the cross connecting blocks. The combination assembly and the limiting assembly are both located within the retaining body.

[0008] Furthermore, the combined component includes: a snap-fit ​​groove and a snap-fit ​​block. The snap-fit ​​groove is provided in multiple sets, which are opened at both ends of multiple sets of support connecting beams and are opened inside the graded connecting seat. The snap-fit ​​block is provided in multiple sets, which are fixedly installed around multiple sets of cross connecting blocks.

[0009] Furthermore, the combined component also includes: adjustment grooves and anchor plates, wherein multiple sets of adjustment grooves are provided and are formed in the middle of multiple sets of cross connecting blocks; and multiple sets of anchor plates are provided and are engaged inside the multiple sets of adjustment grooves.

[0010] Furthermore, the limiting component includes: a knob and a drive turntable. Multiple sets of knobs are provided, and the multiple sets of knobs are rotatably connected inside multiple sets of adjustment slots. Multiple sets of drive turntables are provided, and the multiple sets of drive turntables are rotatably connected inside multiple sets of cross connecting blocks. The multiple sets of drive turntables are fixedly installed at the bottom of the multiple sets of knobs.

[0011] Furthermore, the limiting component also includes: a first connecting rod and a transmission slide rod. The first connecting rod is provided in multiple sets, and the ends of every four sets of the first connecting rods are hinged around a set of drive turntables. The transmission slide rod is provided in multiple sets, and every four sets of the transmission slide rods are slidably connected inside a set of cross connecting blocks. The multiple sets of the transmission slide rods are hinged to the top of multiple sets of the first connecting rods.

[0012] Furthermore, the limiting component also includes: limiting pins, driving blocks, and second connecting rods. Multiple sets of limiting pins are provided, and every two sets of limiting pins are slidably connected to both sides inside a set of locking blocks. Multiple sets of driving blocks are provided, and multiple sets of driving blocks are fixedly installed on the top of multiple sets of transmission slide rods. Multiple sets of second connecting rods are provided, and the ends of every two sets of second connecting rods are hinged to both sides of a set of driving blocks. The top ends of multiple sets of second connecting rods are hinged to the ends of multiple sets of limiting pins.

[0013] Furthermore, the limiting component also includes: a limiting groove and a fixing groove. The limiting groove is provided in multiple sets, and the multiple sets of the limiting groove are opened on both sides inside the multiple sets of snap-fit ​​grooves. The fixing groove is provided in multiple sets, and the multiple sets of the fixing groove are opened at the bottom of the multiple sets of anchor plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this invention features modular components. Through precise alignment of the snap-fit ​​blocks and slots, it enables rapid assembly of the retaining beam, cross-shaped connecting blocks, and tiered connecting seats, eliminating the need for numerous connectors, simplifying the assembly process, and reducing labor input. Simultaneously, the alternating stacking of the tiered connecting seats and the retaining body allows for flexible adaptation to different slope heights, forming a multi-level retaining system that distributes loads and enhances overall stability. The fixed anchor bolts, combined with the compressive force of the anchor plates, firmly fix the retaining body to the slope surface, and the pre-cast tiered connecting seats further strengthen the fixing effect.

[0016] Secondly, this invention features a limiting component. A knob-driven transmission structure engages a limiting pin, inserting it into the limiting groove. This enables synchronized and rapid limiting of all connecting components, ensuring connection reliability and avoiding the tedious manual tightening at each point. The fixing groove at the bottom of the anchor plate engages with the knob, preventing loosening and reducing maintenance frequency due to loose connections.

[0017] This utility model has the advantages of hierarchical combination, quick connection, and convenient transportation. Through modular combination and synchronous limiting design, no complicated operation is required during the installation process. Simply turning the knob can drive the internal transmission structure to move together, so as to realize the synchronous and quick fixation of the support connecting beams or hierarchical connecting seats that are snapped around the cross connecting block. This effectively simplifies the assembly process, significantly shortens the installation time, greatly improves the construction efficiency, and avoids the disadvantages of traditional split structures that rely on a large number of connecting parts and are cumbersome to assemble.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a graded combined retaining device for embankment slope, including a retaining body 1, retaining connecting beams 2, cross connecting blocks 3, graded connecting seats 4, fixed anchors 5, and a combined assembly. Multiple sets of retaining connecting beams 2 are arranged longitudinally and transversely inside the retaining body 1; multiple sets of cross connecting blocks 3 are arranged inside the retaining body 1; graded connecting seats 4 are located at the lower part of the retaining body 1; multiple sets of fixed anchors 5 are arranged, with multiple sets of fixed anchors 5 inserted into the middle of multiple sets of cross connecting blocks 3; and the combined assembly is located inside the retaining body 1.

[0029] The combined components include: a snap-fit ​​groove 201 and a snap-fit ​​block 307. Multiple sets of snap-fit ​​grooves 201 are provided, and multiple sets of snap-fit ​​grooves 201 are opened at both ends of multiple sets of support connecting beams 2 and multiple sets of snap-fit ​​grooves 201 are opened inside the graded connecting seat 4. Multiple sets of snap-fit ​​blocks 307 are provided, and multiple sets of snap-fit ​​blocks 307 are fixedly installed around multiple sets of cross connecting blocks 3.

[0030] The combined components also include: adjustment grooves 301 and anchor plates 501. Multiple sets of adjustment grooves 301 are provided, and multiple sets of adjustment grooves 301 are opened in the middle of multiple sets of cross connecting blocks 3. Multiple sets of anchor plates 501 are provided, and multiple sets of anchor plates 501 are snapped into the interior of multiple sets of adjustment grooves 301.

[0031] The specific usage and function of this embodiment are as follows:

[0032] During construction, the snap-fit ​​blocks 307 around the cross-shaped connecting block 3 are precisely aligned with the snap-fit ​​grooves 201 at both ends of the retaining connecting beam 2 and the snap-fit ​​grooves 201 on the upper and lower sides of the graded connecting seat 4. This allows multiple sets of retaining connecting beams 2 to be spliced ​​longitudinally and transversely to form the frame structure of the retaining body 1, and to achieve a stable splicing between the retaining body 1 and the graded connecting seat 4. By alternating the stacking of the graded connecting seat 4 and the retaining body 1, a multi-level retaining system that adapts to different slope heights can be flexibly formed to meet the requirements of graded stress.

[0033] Subsequently, the anchor rod 5 is passed through the adjustment groove 301 in the middle of the multiple sets of cross connecting blocks 3. Utilizing the snap-fit ​​between the anchor plate 501 and the adjustment groove 301, the supporting body 1 is firmly fixed to the roadbed slope surface through the squeezing force generated by the anchor plate 501 on the cross connecting block 3. At the same time, the graded connecting seat 4 is pre-cast on the roadbed slope surface, which not only provides bottom support for the upper supporting body 1, but also disperses the load transmitted by the supporting body 1 through its own combination with the slope surface, playing a role in graded fixation and enhancing overall stability.

[0034] Example 2:

[0035] Based on Example 1, such as Figures 1 to 5 As shown, it also includes: a limiting component, which is disposed inside the support body 1.

[0036] The limiting components include: knobs 302 and drive discs 303. Multiple sets of knobs 302 are provided, and multiple sets of knobs 302 are rotatably connected inside multiple sets of adjustment slots 301. Multiple sets of drive discs 303 are provided, and multiple sets of drive discs 303 are rotatably connected inside multiple sets of cross connecting blocks 3. Multiple sets of drive discs 303 are fixedly installed at the bottom of multiple sets of knobs 302.

[0037] The limiting component also includes: a first connecting rod 304 and a transmission slide rod 305. The first connecting rod 304 is provided in multiple sets, and the ends of every four sets of the first connecting rod 304 are hinged around a set of drive turntables 303. The transmission slide rod 305 is provided in multiple sets, and every four sets of the transmission slide rod 305 are slidably connected inside a set of cross connecting blocks 3. The multiple sets of transmission slide rods 305 are hinged to the top of multiple sets of the first connecting rod 304.

[0038] The limiting assembly also includes: limiting pins 308, driving blocks 306, and second connecting rods 3061. Multiple sets of limiting pins 308 are provided, and every two sets of limiting pins 308 are slidably connected to the two sides inside a set of locking blocks 307. Multiple sets of driving blocks 306 are provided, and multiple sets of driving blocks 306 are fixedly installed on the top of multiple sets of transmission slide rods 305. Multiple sets of second connecting rods 3061 are provided, and the ends of every two sets of second connecting rods 3061 are hinged to the two sides of a set of driving blocks 306. The tops of multiple sets of second connecting rods 3061 are hinged to the ends of multiple sets of limiting pins 308.

[0039] The limiting component also includes: a limiting groove 202 and a fixing groove 502. The limiting groove 202 is provided in multiple sets, and the multiple sets of limiting grooves 202 are opened on both sides inside the multiple sets of snap-fit ​​grooves 201. The fixing groove 502 is provided in multiple sets, and the multiple sets of fixing grooves 502 are opened at the bottom of the multiple sets of anchor plates 501.

[0040] The specific usage and function of this embodiment are as follows:

[0041] After the snap-fit ​​block 307 is snapped into the snap-fit ​​groove 201, the knob 302 is turned. The knob 302 will drive the drive turntable 303 to rotate synchronously. When the drive turntable 303 rotates, it causes the first connecting rod 304 to swing. The swing of the first connecting rod 304 will cause the transmission slide rod 305 to slide inside the cross connecting block 3. The sliding of the transmission slide rod 305 will cause the drive block 306 to move. The movement of the drive block 306 will cause the two sets of opposing second connecting rods 3061 to swing. The swing of the two sets of opposing second connecting rods 3061 will cause the two sets of limit pins 308 to slide relative to each other inside the snap-fit ​​block 307. Finally, the limit pins 308 will be inserted into the limit groove 202, thereby realizing the simultaneous and rapid and stable limiting of the support connecting beams 2 or graded connecting seats 4 installed around the cross connecting block 3, ensuring the reliability of the connection of each component.

[0042] When the anchor rod 5 passes through the cross connecting block 3 and the anchor plate 501 is used to fix the cross connecting block 3 to the roadbed slope, the fixing groove 502 at the bottom of the anchor plate 501 will be precisely engaged with the upper part of the knob 302, thereby effectively limiting the knob 302 and preventing the knob 302 from loosening due to external forces or other factors during the use of the device. This avoids loosening of the connection of each connecting part and ensures the structural stability of the entire support device.
