Description

Technical Field

[0001] This invention belongs to the field of ecological slope protection technology, specifically, it relates to a self-locking geopolymer concrete prefabricated ecological bank protection structure. Background Technology

[0002] Geopolymer concrete is a new type of green inorganic cementitious material that has outstanding advantages such as high strength, high impermeability, frost resistance and corrosion resistance, low carbon and environmental protection, and rapid curing. Compared with ordinary silicate concrete, it is more suitable for long-term service conditions in complex water environments in water conservancy. It is a high-quality alternative material for bank slope protection components. Therefore, prefabricated geopolymer concrete is widely used in ecological bank protection.

[0003] However, most of the prefabricated ecological revetment structures currently on the market are assembled using modular prefabricated components. They rely on the tight fit and compression of the component end faces, as well as the friction between the components and the bank slope foundation and the upper and lower layer components to achieve assembly and fixation. This passive fixing method, which is purely based on fit and friction, can only meet the basic protection requirements under conditions of gentle working conditions and ideal construction quality. Once applied to complex hydraulic engineering conditions such as frequent water level fluctuations, continuous water scouring, wind and wave impact, uneven soil settlement, and freeze-thaw cycles, its inherent defects will be continuously amplified, which can easily lead to various engineering hazards.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] The self-locking geopolymer concrete prefabricated ecological revetment structure consists of multiple geopolymer concrete blocks that are connected end to end, adhered to each other, and laid on the revetment base.

[0007] Each of the aforementioned geopolymer concrete blocks is equipped with an anchor plate at its bottom. The anchor plate is inserted into the revetment. A horizontal plate is rotatably installed inside the anchor plate. Normally, the horizontal plate is stored in the inner cavity of the anchor plate. After the anchor plate is inserted into place, it drives the horizontal plate to rotate 90 degrees. The horizontal plate and the anchor plate form a cross-shaped anchoring configuration. The horizontal plates of adjacent geopolymer concrete blocks are opposite each other, and a self-locking component is provided between them.

[0008] The self-locking assembly includes an anchor rod that movably passes through two horizontal plates and is inserted into the revetment. A pair of locking blocks are rotatably installed on the anchor rod, which are used to lock into the bottom of the horizontal plates. The side walls of the locking blocks are respectively provided with insertion inclined surfaces and reset inclined surfaces for easy assembly and disassembly. A pull rod is installed inside the anchor rod by thread, and a ball bearing is installed at the bottom of the pull rod. The ball bearing fits against the inner side wall of the locking block, and the inner side wall of the locking block is inclined. By controlling the vertical position of the ball bearing, the locking block is prevented from retracting inward, thereby achieving locking and preventing the locking block from falling off.

[0009] In a preferred embodiment of the present invention, the revetment is provided with an inner groove, and the bottom of the polymer concrete block is provided with a plurality of friction protrusions, the friction protrusions being tightly fitted with the inner groove. The top of the revetment is also provided with a slope top capping edge beam, which presses against the surface of the polymer concrete block located above.

[0010] In a preferred embodiment of the present invention, the surface of the polymer concrete block is provided with several pairs of anti-slip grooves, and several pairs of insert rods are installed on the inner sidewall of the groove. The axial direction of the insert rods is the same as the flat connection direction of the polymer concrete block. The inside of the polymer concrete block is provided with a through hole, which is movably connected to the insert rod. The end of the insert rod is in contact with the sidewall of the top capping beam.

[0011] In a preferred embodiment of the present invention, a sliding sleeve is precast and embedded inside the geopolymer concrete block. The sliding sleeve is integrally formed with the geopolymer concrete block. A rotating rod is rotatably installed inside the sliding sleeve. A fixed seat is installed at the bottom of the rotating rod. A pair of horizontal plates are installed on the side wall of the fixed seat. The pair of horizontal plates are arranged with different heights. The staggered arrangement of the horizontal plates is used to realize the layered alignment and sequential stacking of the horizontal plates of adjacent blocks, avoiding assembly interference and improving the fit of the blocks and the overall assembly stability. The side wall of the anchor plate is also provided with an internal groove, which facilitates the storage of the pair of horizontal plates.

[0012] In a preferred embodiment of the present invention, a circular plate is installed on the top of the rotating rod, and a hexagonal screw block is installed at the center of the circular plate. The circular plate and the hexagonal screw block are placed inside an installation groove opened on the surface of the geopolymer concrete block.

[0013] In a preferred embodiment of the present invention, a protruding rod is installed on the side wall of the circular plate, and a pair of stop rods are installed on the inner side wall of the mounting groove. The pair of stop rods are located on the outer side of the circular plate, and the central angle formed by the pair of stop rods is 90 degrees. The protruding rod rotates between the pair of stop rods to position the rotation angle of the circular plate.

[0014] In a preferred embodiment of the present invention, the sidewall of the geopolymer concrete block is provided with a through hole, the anchor rod is movably inserted through the through hole, the bottom of the anchor rod is also provided with a pointed end, the horizontal plate is also provided with an installation hole, the anchor rod is movably inserted through the installation hole, the sidewall of the anchor rod is also provided with a guide block, the sidewall of the installation hole is also provided with a guide groove, and the guide block is movably inserted into the guide groove.

[0015] In a preferred embodiment of the present invention, the side wall of the anchor rod has a notch, and a positioning shaft is rotatably installed inside the notch. The positioning shaft is rotatably connected to the locking block. A limit block is installed on the top of the locking block to prevent the locking block from sliding out of the notch. When the anchor rod is pressed down for assembly, the insertion inclined surface is pressed and drives the locking block to retract inward, allowing the locking block to pass through the horizontal plate. When the anchor rod is pulled up, the reset inclined surface is forced to drive the locking block to retract inward again, releasing the locking block limit and facilitating the removal and disassembly of the anchor rod.

[0016] In a preferred embodiment of the present invention, a countersunk groove is provided at the end of the through hole, a threaded rod is installed at the top of the tie rod and the threaded rod moves through the top of the anchor rod, a pad is sleeved on the threaded rod, and a locking nut is screwed on the end of the threaded rod and the locking nut is placed inside the countersunk groove.

[0017] In a preferred embodiment of the present invention, a sliding plate is installed at the center of the pull rod, and a limiting rod is slidably installed through the sliding plate. The top of the limiting rod is installed at the top of the inner cavity of the anchor rod, and a limiting plate for preventing detachment is installed at the bottom of the limiting rod. The diameter of the limiting plate is larger than the diameter of the limiting rod.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention utilizes a rotatable, cross-shaped anchoring configuration at the bottom of the blocks, combined with self-locking components that align adjacent blocks, to form an integrated anchoring and locking structure. The cross-shaped anchoring structure, composed of anchor plates and rotating horizontal plates, penetrates deep into the revetment substrate, effectively restraining the vertical lifting and horizontal displacement of the blocks under conditions such as water level fluctuations, water erosion, and soil settlement. Simultaneously, the top-locking self-locking structure formed by anchor rods, locking blocks, and ball bearings provides rigid locking to the horizontal plates of adjacent blocks, strengthening the overall connection between blocks, improving the problem of easy loosening and detachment of components, and stably maintaining the overall assembly shape of the revetment, ensuring the structural integrity and reliability of the revetment during long-term service.

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0036] Example 1:

[0037] like Figures 1 to 12 As shown, the self-locking geopolymer concrete prefabricated ecological revetment structure includes multiple geopolymer concrete blocks 3 that are connected end to end, adhered to each other, and laid on the revetment 1 substrate.

[0038] Each polymer concrete block 3 has an anchor plate 7 installed at its bottom. The anchor plate 7 is inserted into the revetment 1. A horizontal plate 16 is rotatably installed inside the anchor plate 7. Under normal conditions, the horizontal plate 16 is stored in the inner cavity of the anchor plate 7. After the anchor plate 7 is inserted into place, the horizontal plate 16 is driven to rotate 90 degrees. The horizontal plate 16 and the anchor plate 7 form a cross-shaped anchoring configuration. The horizontal plates 16 of adjacent polymer concrete blocks 3 are opposite each other, and a self-locking component is provided between them.

[0039] The self-locking assembly includes an anchor bolt 22, which movably passes through two horizontal plates 16 and is inserted into the revetment 1. A pair of locking blocks 24 are rotatably installed on the anchor bolt 22. The locking blocks 24 are used to lock into the bottom of the horizontal plates 16. The side walls of the locking blocks 24 are respectively provided with insertion inclined surfaces 26 and reset inclined surfaces 27 for easy assembly and disassembly. A pull rod 30 is screwed into the anchor bolt 22, and a ball bearing 29 is installed at the bottom of the pull rod 30. The ball bearing 29 fits against the inner side wall of the locking block 24, and the inner side wall of the locking block 24 is inclined. By controlling the vertical position of the ball bearing 29, the locking block 24 is prevented from retracting inward, thereby locking and preventing the locking block 24 from falling off.

[0040] like Figures 1 to 12As shown in the specific embodiment, the revetment 1 has an inner groove 2, and the bottom of the polymer concrete block 3 is provided with several pairs of friction protrusions 6. The friction protrusions 6 are tightly fitted with the inner groove 2. The top of the revetment 1 is also provided with a slope top capping edge beam 5, which presses against the surface of the polymer concrete block 3 located above. Through the concave-convex fit between the inner groove 2 and the friction protrusions 6, combined with the squeezing and limiting effect of the slope top capping edge beam 5, the displacement of the polymer concrete block 3 can be restrained, which can moderately improve the overall fit and foundation stability after the blocks are laid.

[0041] like Figures 1 to 12 As shown, furthermore, the surface of the polymer concrete block 3 is provided with several pairs of anti-slip grooves, and several pairs of insert rods 4 are installed on the inner sidewall of the groove 2. The axial direction of the insert rods 4 is the same as the flat joint direction of the polymer concrete block 3. The inside of the polymer concrete block 3 is provided with a through hole 38, which is movably connected to the insert rod 4. The end of the insert rod 4 is in contact with the sidewall of the top capping beam 5. With the through-fitting structure of the insert rod 4 and the through hole 38, the splicing displacement of the polymer concrete block 3 can be auxiliaryly constrained. Combined with the anti-slip groove structure on the block surface, the splicing accuracy and surface anti-slip performance of the blocks can be improved within a certain range, and the overall assembly effect can be optimized.

[0042] Example 2:

[0043] The difference between the above embodiments and this embodiment is that: Figures 1 to 12 As shown, a precast sliding sleeve 8 is embedded inside the polymer concrete block 3. The sliding sleeve 8 is integrally formed with the polymer concrete block 3. A rotating rod 9 is rotatably installed inside the sliding sleeve 8. A fixed seat 15 is installed at the bottom of the rotating rod 9. A pair of horizontal plates 16 are installed on the side wall of the fixed seat 15. The pair of horizontal plates 16 are arranged with different heights. The staggered arrangement of the horizontal plates 16 is used to achieve layered alignment and sequential stacking of the horizontal plates 16 of adjacent blocks, avoiding assembly interference and improving the fit and overall assembly stability of the blocks. The side wall of the anchor plate 7 is also provided with an internal groove 18, which facilitates the storage of the pair of horizontal plates 16. The integrally formed sliding sleeve 8 ensures the rotational stability of the rotating rod 9. Combined with the staggered horizontal plate 16 structure and the internal groove 18 storage design, structural interference problems during block assembly can be reduced, which helps to improve the alignment and fit accuracy and assembly adaptability of adjacent polymer concrete blocks 3.

[0044] like Figures 1 to 12As shown, in a specific embodiment, a circular plate 10 is installed on the top of the rotating rod 9, and a hexagonal screw block 11 is installed at the center of the circular plate 10. The circular plate 10 and the hexagonal screw block 11 are placed inside the mounting groove 14 opened on the surface of the polymer concrete block 3. Retaining the hexagonal screw block 11 and the circular plate 10 inside the mounting groove 14 keeps the outer surface of the polymer concrete block 3 flat, reduces damage to the adjustment structure from external impacts, and facilitates convenient adjustment of the rotating rod 9 later.

[0045] like Figures 1 to 12 As shown, furthermore, a protruding rod 12 is installed on the side wall of the circular plate 10, and a pair of stop rods 13 are installed on the inner side wall of the mounting groove 14. The pair of stop rods 13 are located on the outer side of the circular plate 10, and the central angle formed by the pair of stop rods 13 is ninety degrees. The protruding rod 12 rotates between the pair of stop rods 13 to position the rotation angle of the circular plate 10. By utilizing the limiting and cooperating structure of the protruding rod 12 and the ninety-degree angle stop rods 13, the rotation angle of the circular plate 10 and the rotating rod 9 can be precisely limited, which facilitates the standardization of the rotation stroke of the horizontal plate 16 and improves the accuracy of the anchoring structure assembly.

[0046] Example 3:

[0047] The difference between the above embodiments and this embodiment is that: Figures 1 to 12 As shown, the sidewall of the geopolymer concrete block 3 has a through hole 19, through which the anchor rod 22 movably passes. A pointed tip 23 is also installed at the bottom of the anchor rod 22. An installation hole 17 is also provided on the horizontal plate 16, through which the anchor rod 22 movably passes. A guide block 37 is also installed on the sidewall of the anchor rod 22, and a guide groove 20 is provided on the sidewall of the installation hole 17. The guide block 37 is movably inserted into the guide groove 20. Through the insertion and engagement of the guide block 37 and the guide groove 20, combined with the pointed tip 23 structure at the bottom of the anchor rod 22, the insertion resistance of the anchor rod 22 can be reduced, assisting in the precise alignment of the anchor rod 22 and the installation hole 17, thus improving the smoothness and alignment accuracy of the anchor rod assembly.

[0048] like Figures 1 to 12 As shown, in a specific embodiment, the anchor rod 22 has a notch 39 on its side wall. A positioning shaft 25 is rotatably installed inside the notch 39. The positioning shaft 25 is rotatably connected to the locking block 24. A limit block 28 is installed on the top of the locking block 24 to prevent the locking block 24 from sliding out of the notch 39. When the anchor rod 22 is pressed down for assembly, the insertion inclined surface 26 is pressed and drives the locking block 24 to retract inward, allowing the locking block 24 to pass through the horizontal plate 16. When the anchor rod 22 is pulled up, the reset inclined surface 27 is forced to drive the locking block 24 to retract inward again, releasing the locking block 24 from its limit position, making it easy to pull out and disassemble the anchor rod 22. Relying on the limiting and protective structure of the limit block 28, the risk of the locking block 24 falling off can be reduced. Combined with the bidirectional guiding structure of the insertion inclined surface 26 and the reset inclined surface 27, it can adapt to the assembly and disassembly operations of the anchor rod 22, improving the convenience of structural assembly and disassembly.

[0049] like Figures 1 to 12 As shown, further, a countersunk groove 21 is provided at the end of the through hole 19. A threaded rod 31 is installed on the top of the pull rod 30, and the threaded rod 31 moves through the top of the anchor rod 22. A pad 32 is sleeved on the threaded rod 31, and a locking nut 33 is screwed onto the end of the threaded rod 31. The locking nut 33 is placed inside the countersunk groove 21. A sliding plate 34 is installed at the center of the pull rod 30. A limit rod 35 is slidably installed through the sliding plate 34. The top of the limit rod 35 is installed at the top of the inner cavity of the anchor rod 22, and a limit plate 36 for preventing detachment is installed at the bottom of the limit rod 35. The diameter of the limit plate 36 is larger than the diameter of the limit rod 35. The countersunk groove 21 accommodates the locking nut 33, which keeps the structure flat and protects the locking structure. Combined with the limiting sliding structure of the sliding plate 34, the limit rod 35, and the limit plate 36, the movement stroke of the pull rod 30 can be moderately constrained, reducing the possibility of excessive deformation of the structure and improving the stability of the locking structure.

[0050] During the construction and assembly of the self-locking geopolymer concrete prefabricated ecological revetment structure, the geopolymer concrete blocks 3 are first positioned and laid based on the revetment 1 substrate. The pre-set inner groove 2 on the surface of the revetment 1 fits tightly with the friction protrusion 6 on the bottom of the block, initially limiting the horizontal slippage and vertical displacement of the block. At the same time, the insert rod 4 on the inner wall of the revetment 1 passes through the through hole 38 inside the block. Utilizing the structural characteristic that the insert rod 4 and the block are in the same direction, the splicing displacement of the block is further constrained, ensuring that multiple geopolymer concrete blocks 3 are laid end to end and tightly fitted. Finally, the top slope capping edge sealing beam 5 on the top of the revetment 1 is used to press and fit the block to the surface of the uppermost block, completing the initial fixation of the overall block laying.

[0051] During the block laying and positioning process, the anchor plate 7 at the bottom of the geopolymer concrete block 3 is inserted into the revetment 1 simultaneously with the block laying. Under normal conditions, the horizontal plate 16 is completely housed in the inner cavity of the anchor plate 7 and the built-in groove 18. The housed structure can avoid structural interference during the block laying process and ensure that the blocks are laid in place. After all the blocks are laid in place, the anchoring and locking operation can be carried out. The operator drives the circular plate 10 and the rotating rod 9 to rotate through the hexagonal screw block 11 in the mounting groove 14 on the block surface. The two sets of stop bars 13 with a 90-degree angle between the protruding rod 12 on the side wall of the circular plate 10 and the inner side wall of the mounting groove 14 form a rotation limit. The rotating rod 9 is precisely controlled to drive the bottom fixing seat 15 and the horizontal plate 16 to rotate 90 degrees, so that the horizontal plate 16 rotates out of the anchor plate 7 and forms a cross-shaped anchoring configuration with the anchor plate 7. Among them, the two horizontal plates 16 on the side wall of the fixing seat 15 adopt a staggered height structure design, which allows the horizontal plates 16 of adjacent blocks to form a layered alignment and stacked fit during assembly, thereby avoiding positional interference problems in the assembly process of adjacent blocks from the structural source, and further improving the splicing and fitting accuracy and overall assembly stability between multiple sets of blocks.

[0052] After the horizontal plates 16 of the adjacent polymer concrete blocks 3 are aligned in pairs, the anchor rods 22 penetrate the through holes 19 in the sidewalls of the blocks and the mounting holes 17 on the surface of the horizontal plates 16. Simultaneously, the guide blocks 37 on the sidewalls of the anchor rods 22 engage with the guide grooves 20 on the sidewalls of the mounting holes 17, achieving precise alignment and installation of the anchor rods 22. The pointed tip 23 at the bottom of the anchor rods 22 reduces the insertion resistance, ensuring smooth insertion and fixation of the anchor rods 22 into the revetment 1. During the downward pressing and assembly of the anchor rods 22, the insertion ramp 26 on the outer side of the locking block 24 is pressure-driven, causing the locking block 24 to retract inwards, allowing it to smoothly pass through the mounting holes 17 of the horizontal plates 16 and extend to the bottom of the horizontal plates 16.

[0053] Next, by tightening the locking nut 33 at the top of the threaded rod 31, the threaded rod 31 and the pull rod 30 are moved vertically upward as a whole. The ball bearing 29 at the bottom of the pull rod 30 moves upward and fits against the inner wall of the inclined locking block 24. The pushing force of the ball bearing 29 pushes the locking block 24 outward, thereby locking it at the bottom of the mounting hole 17, thus ensuring that the anchor rod 22 and the cross plate 16 will not separate. During the above process, the sliding plate 34 in the middle of the pull rod 30 can slide vertically along the limiting rod 35. With the help of the limiting plate 36 with a larger diameter at the bottom of the limiting rod 35, the downward stroke of the pull rod 30 is effectively limited, avoiding excessive downward pressure that could cause structural deformation and damage. The locking nut 33 is housed inside the countersunk groove 21 at the end of the through hole 19, which not only ensures the flatness of the structure but also protects the locking structure from loosening caused by external impact.

[0054] When the revetment structure needs to be inspected, disassembled, or replaced, the locking nut 33 is loosened in the reverse direction. The pull rod 30 drives the ball bearing 29 to move down, releasing the top locking state of the locking block 24. Then, the anchor rod 22 is pulled up. At this time, the reset slope 27 on the outer side of the locking block 24 contacts the bottom of the mounting hole 17 and is subjected to force, which drives the locking block 24 to retract inward again, so that the locking block 24 is released from the locking limit of the horizontal plate 16, and the anchor rod 22 can be pulled out smoothly from the block and the revetment 1.

[0055] The entire structure, through the cooperation of multiple limiting, cross anchoring and ball self-locking structure, realizes the prefabricated rapid installation and stable locking of the geopolymer concrete block 3. Combined with the concave-convex fit between the block and the revetment 1, the insertion rod through-limiting, and the overall pressing effect of the top capping and sealing beam 5, it comprehensively improves the overall structural strength, anti-slip performance and overall stability of the ecological revetment. At the same time, the quick disassembly and assembly structure design effectively improves the convenience of revetment operation, maintenance and repair.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
