Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to an auxiliary device and filling method for filling large-volume ecological geotextile bags. Background Technology

[0002] In some areas that prioritize ecological protection, large-volume ecological geotextile bags are widely used in coastline protection projects. These projects construct ecological slope protection structures, which effectively enhance the seawall's erosion resistance and engineering durability while also providing ecological protection.

[0003] However, large-volume geotextile bags, such as those used in an airport runway upgrade project (measuring 2.4m × 1.8m × 0.65m and weighing approximately 4.7 tons when filled), present significant construction challenges. Traditional methods have numerous drawbacks:

[0004] 1. Manual operation is impractical: Relying entirely on manual labor for loading and placing such heavy objects is inefficient and unsafe;

[0005] 2. The crane + sling method has prominent problems: risk of local damage: stress concentration in the contact area between the sling and the geotextile bag can easily lead to wear and even local damage to the surface of the bag. Especially when the sling is not properly arranged, the operation is cumbersome and inefficient: the process of properly arranging and fixing the sling of large geotextile bags is time-consuming and laborious, which significantly reduces construction efficiency.

[0006] 3. Modified rock grab buckets are not suitable: These tools will apply excessive pressure to the geotextile bags, causing the bags to deform or even the seams to fail.

[0007] 4. High requirements for uniformity of filler: Uneven distribution of filler inside large-volume geobags will directly affect the stress balance of the bag structure, thereby endangering the overall stability of the project.

[0008] 5. Difficulty in precise positioning: Geotextile bags are heavy and bulky, making precise placement in underwater or harsh environments particularly complex and time-consuming. Summary of the Invention

[0009] The purpose of this invention is to provide an auxiliary device and filling method for filling large-volume ecological geotextile bags, so as to solve the operational efficiency problem mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] An auxiliary device for filling large-volume geotextile bags includes a rectangular base placed stably on the ground, with placement execution modules symmetrically placed on the upper surface of the rectangular base, and geotextile bags placed on the placement execution modules; a vertical mast is fixedly installed in the middle of the rectangular base, and a lifting seat is mounted on the vertical mast; a lifting drive assembly connects the vertical mast and the lifting seat; a rotating cylinder is rotatably connected to the upper surface of the lifting seat, and a rotation drive assembly for driving the rotating cylinder is also installed on the lifting seat; a sleeve is fitted on the outer side of the rotating cylinder, and the upper part of the sleeve is fitted on the outer side of the vertical mast; a hopper is fixedly connected to the outer side of the sleeve through a fixed seat, and a locking assembly for fixing the geotextile bag opening is provided on the lower outer side of the hopper.

[0012] Preferably, the upper surface of the rectangular base is symmetrically provided with positioning frames, and the upper surface of the positioning frames is arranged in an arc shape, and the positioning frames are fitted and supported on the lower surface where the execution module is placed.

[0013] Preferably, the placement execution module is configured in a J-shape, and a quick-connector for hinged connection with the excavator boom is installed on the outside of the placement execution module.

[0014] Preferably, the lifting drive assembly includes a lifting motor fixedly installed on the outer side of the lower part of the upright mast, and a threaded rod is fixedly installed on the output end of the lifting motor. A lifting cylinder is threadedly connected to the outer side of the threaded rod. The lifting cylinder is fixedly installed on the lower surface of the lifting seat, and the threaded rod drives the lifting cylinder to adjust the lifting seat during rotation.

[0015] Preferably, the rotary drive assembly includes a rotary motor fixedly mounted on the lifting seat, and a drive gear is fixedly mounted on the output end of the rotary motor. A transmission gear is fixedly mounted on the lower outer side of the rotary cylinder, and the drive gear and the transmission gear are meshed together.

[0016] Preferably, the rotating cylinder and the sleeve form a telescopic structure, and a rotating seat is rotatably mounted on the lower outer side of the sleeve, and a first spring is fixedly connected between the rotating seat and the lifting seat.

[0017] Preferably, the rotating cylinder has a guide groove with a wave-like structure, and a guide post is fixedly installed on the lower inner wall of the sleeve. The guide post is located inside the guide groove, and the guide post slides along the guide groove during the sleeve's lifting and lowering adjustment to drive the sleeve to rotate.

[0018] Preferably, the locking assembly includes a positioning clamp that is uniformly and elastically rotatably installed on the lower outer side of the hopper, and an adjusting ring is lifted and sleeved on the lower outer side of the hopper. A second spring is fixedly connected between the hopper and the adjusting ring. During the downward movement of the adjusting ring, the positioning clamp is pushed to rotate elastically, and the positioning clamp fixes the opening of the geotextile bag sleeved on the outer side of the hopper during the elastic rotation.

[0019] A method for filling large-volume ecological geotextile bags includes the following steps:

[0020] S1, Equipment preparation stage;

[0021] Anchor the rectangular base to the flat foundation and set up drainage ditches around it to prevent water accumulation on the site; install the upright mast vertically on the rectangular base, ensuring that there are no impurities on the connection surface; place the placement execution module above the positioning frame; fix the fixed seat and hopper to the outside of the sleeve, and control the lifting motor to drive the hopper to adjust its height to match the size of the geotextile bag.

[0022] S2, Geobag filling stage;

[0023] Start the drive gear to rotate and adjust the hopper, ensuring the outlet is precisely aligned with the geotextile bag on the execution module station. Secure the geotextile bag opening to the bottom of the hopper using the locking assembly. Operate the excavator to inject sand into the hopper. Perform layered vibration filling: control the sand flow rate to ensure even distribution of filler material inside the geotextile bag. Focus on filling the four corners of the bag to eliminate gaps. Fill to a height of 200mm above the bag opening to ensure a compaction of ≥95%. Verification standard: straight edges of the bag without collapse.

[0024] S3, Bag sealing and transfer stage;

[0025] Release the geotextile bag fixing clamps and fold the bag opening ≥3 times to form a sealing layer; use anti-corrosion ropes to tie the bag opening with a double flat knot and apply elastic sealant to cover the knot; rotate the hopper system 180° to switch to the standby position; the excavator grabs the execution module and geotextile bag through the quick connector, and moves it to the target position at a low position with a height ≤0.5m off the ground.

[0026] S4, Precision Placement and Leveling Stage;

[0027] Maneuver the excavator to slide and position the geotextile bag tangentially along the J-shaped curved surface of the placement module, adjusting it by ±5° if necessary to assist in bag removal; after the bag is in place, apply vertical pressure (≤10kN / m) to the bottom surface of the placement module. 2 Level the top surface of the bag; verify the placement accuracy: plane position deviation ≤ 50mm; gap between adjacent bags ≤ 100mm; flatness of the bag top ≤ 3°.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the auxiliary equipment and filling method for filling large-volume ecological geotextile bags realizes full-process mechanized filling, significantly improves filling efficiency, completely eliminates the risks of high-risk environment operation, and eradicates the structural risks caused by the uniformity of filling material. The specific contents are as follows;

[0029] 1. Breakthrough improvement in filling efficiency, realizing full-process mechanized filling (filling → compaction → transfer), single bag filling time ≤ 8 minutes, which is 300%+ more efficient than manual operation; the hopper supports rotary positioning feeding, which is seamlessly connected with the placement execution module placement station, eliminating equipment waiting time and improving the project progress guarantee rate by 40%.

[0030] 2. By remotely controlling the placement of the execution module through the excavator, construction personnel are completely removed from dangerous scenarios such as turbulent water areas with a depth greater than 1.5m and slope areas with a gradient greater than 45°. Simulation verification shows that the construction accident rate has decreased by 92% after the application of the equipment (compared to traditional sling transport), completely eliminating the risk of working in high-risk environments.

[0031] 3. Millimeter-level engineering precision can be repeatedly achieved through the placement of the curved surface guide module and the excavator's hydraulic micro-control, enabling: planar positioning error ≤50mm (underwater conditions ≤80mm), bag gap control accuracy ≤5% of bag width, and bag top leveling and compaction deviation ≤3%.

[0032] 4. Eliminate structural risks caused by uneven filler uniformity. The vibration layered filling process ensures that the bag density is ≥95%, and the compaction fluctuation range of the filler in the four corner areas is ≤2%, thus preventing slope instability caused by local collapse from the root.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1:

[0046] Existing geotextile bag filling auxiliary equipment has a fixed structure, making it inconvenient to adjust according to bag size, and its operation is complex with limited applicability. To solve this technical problem, this embodiment discloses the following technical content. Please refer to [link / reference]. Figures 1-5 and Figures 9-10 As shown; an auxiliary device for filling large-volume geotextile bags includes a rectangular base 1 placed stably on the ground, with placement execution modules 3 symmetrically placed on the upper surface of the rectangular base 1, and geotextile bags 4 placed on the placement execution modules 3. A vertical mast 5 is vertically fixedly installed in the middle of the rectangular base 1, and a lifting seat 6 is installed on the vertical mast 5. A lifting drive assembly is connected between the vertical mast 5 and the lifting seat 6. A rotating cylinder 10 is rotatably connected to the upper surface of the lifting seat 6, and a rotation drive assembly for driving the rotating cylinder 10 to rotate is also installed on the lifting seat 6. A sleeve 14 is sleeved on the outside of the rotating cylinder 10, and the upper part of the sleeve 14 is sleeved on the outside of the vertical mast 5. A hopper 20 is fixedly connected to the outside of the sleeve 14 through a fixing seat 19. At the same time, a locking assembly for fixing the mouth of the geotextile bag 4 is provided on the lower outer side of the hopper 20.

[0047] A positioning frame 2 is symmetrically arranged on the upper surface of the rectangular base 1, and the upper surface of the positioning frame 2 is arranged in an arc shape. The positioning frame 2 fits and supports the lower surface of the execution module 3. The execution module 3 is arranged in a J-shape, and a quick connector for hinged with the excavator boom is installed on the outside of the execution module 3. The lifting drive assembly includes a lifting motor 7 fixedly installed on the lower outer side of the vertical mast 5, and a threaded rod 8 is fixedly installed on the output end of the lifting motor 7. A lifting cylinder 9 is threadedly connected to the outer side of the threaded rod 8. The lifting cylinder 9 is fixedly installed on the lower surface of the lifting seat 6. During the rotation of the threaded rod 8, the lifting cylinder 9 drives the lifting seat 6 to adjust its height. The rotation drive assembly includes a rotation motor 11 fixedly installed on the lifting seat 6, and a drive gear 12 is fixedly installed on the output end of the rotation motor 11. A transmission gear 13 is fixedly installed on the lower outer side of the rotation cylinder 10, and the drive gear 12 and the transmission gear 13 are meshed together.

[0048] Before construction, the rectangular base 1 is anchored on a flat foundation. The upright mast 5 is then vertically installed into the slot on the rectangular base 1, ensuring the connection surface is free of impurities. Next, the execution module 3 is placed above the positioning frame 2. Then, based on the height of the geotextile bag 4, the lifting motor 7 drives the threaded rod 8 to rotate. This allows the threaded rod 8 to adjust the position and height of the lifting cylinder 9 and the lifting seat 6 through the threaded connection. Finally, the rotary motor 11 is started, which, through the transmission of the drive gear 12 and the transmission gear 13... The rotating cylinder 10 and sleeve 14 are driven to rotate, thereby adjusting the angle of the hopper 20. The geotextile bag 4 is placed on the placement execution module 3 to ensure that the opening of the geotextile bag 4 can be fitted onto the lower outer side of the hopper 20. Before the opening is fitted, the adjusting ring 21 is pushed upward, causing the positioning clamp 23 to rotate and expand. After the opening is fitted, the adjusting ring 21 is released, causing the adjusting ring 21 to elastically move downward, pushing multiple positioning clamps 23 to rotate synchronously, thereby tightening and fixing the opening of the bag. Then, the excavator is operated to inject sand into the hopper 20.

[0049] The J-shaped curved surface profile of the placement execution module 3 transforms the weight of the geotextile bag into a uniformly distributed normal load, avoiding local stress concentration. The tool suspension point is perpendicular to the overall center of gravity, ensuring that the system's center of gravity remains within the line of action of the excavator's lifting force during hoisting, suppressing overturning moments. The geotextile bag 4 is smoothly positioned along the tangential direction under the constraint of the J-shaped curved surface, achieving precise placement through gravity self-adjustment. Since the placement execution module 3 primarily bears the uniformly distributed load from the geotextile bag during transport, its mechanical design hinges on the thickness of the steel plate to prevent severe deformation and failure during operation. To determine the steel plate thickness, this stress state can be roughly equated to a cantilever slab bearing a uniformly distributed load. A simplified calculation method is as follows:

[0050] Load type: The weight Q of geotextile bag 4 is evenly distributed on the bottom surface of the cantilever slab (the lower edge of the arc-shaped clamp arm).

[0051] The width b of the plate: the width of the part that contacts the geotextile bag held by the tool.

[0052] Cantilever length L: The length of the cantilever section (the protruding part of the clamp arm).

[0053] Material properties: The tool is made of a homogeneous material (such as steel plate), with an elastic modulus E and yield strength of... Known.

[0054] Calculation formula

[0055] When a cantilever slab is subjected to a uniformly distributed load, the maximum bending moment occurs at the fixed end, as calculated below:

[0056] Maximum bending moment Mmax:

[0057]

[0058] Uniformly distributed load per unit area.

[0059] Q: Total weight of geotextile bags 4.

[0060] b: Width of the board.

[0061] L: Length of the cantilever slab.

[0062] The flexural strength W of the cross section (simplified to a rectangle):

[0063]

[0064] t: Sheet thickness (can be taken as the thinnest part where the tool is placed)

[0065] Strength requirements:

[0066]

[0067] Calculation of plate thickness t

[0068] By substituting into the formula, the minimum required thickness t of the plate can be calculated:

[0069]

[0070] After determining the thickness of the steel plate, considering the impact of possible dynamics, wind, or other accidental factors on its stability and strength during operation, steel ribs are appropriately added after placing the execution module 3 to increase rigidity.

[0071] Example 2:

[0072] The technical content disclosed in this embodiment is a further improvement based on the above-described embodiment one. Existing geotextile bag filling auxiliary equipment is inconvenient for uniformly filling sand, resulting in uneven sand distribution inside the bag. To further solve this technical problem, this embodiment discloses the following technical content, such as... Figures 5-10 As shown;

[0073] The rotating cylinder 10 and the sleeve 14 form a telescopic structure. A rotating seat 15 is rotatably installed on the lower outer side of the sleeve 14. A first spring 16 is fixedly connected between the rotating seat 15 and the lifting seat 6. A guide groove 17 is provided on the rotating cylinder 10, and the guide groove 17 is arranged in a wave-like structure. A guide post 18 is fixedly installed on the lower inner wall of the sleeve 14. The guide post 18 is located inside the guide groove 17. During the lifting and adjusting process of the sleeve 14, the guide post 18 slides along the guide groove 17 to drive the sleeve 14 to rotate. The locking assembly includes a positioning clamp 23 that is uniformly and elastically rotatably installed on the lower outer side of the hopper 20. An adjusting ring 21 is lifted and sleeved on the lower outer side of the hopper 20. A second spring 22 is fixedly connected between the hopper 20 and the adjusting ring 21. At the same time, during the downward movement of the adjusting ring 21, the positioning clamp 23 is pushed to rotate elastically. During the elastic rotation of the positioning clamp 23, the opening of the geotextile bag 4 sleeved on the outside of the hopper 20 is fixed.

[0074] As sand falls into hopper 20, the overall mass of hopper 20 increases. This causes hopper 20 to move up and down outside rotating cylinder 10 via fixed base 19, driving sleeve 14. Rotating cylinder 10 is locked by rotating motor 11, causing guide post 18 on the inner side of sleeve 14 to slide to the bottom along guide groove 17 on rotating cylinder 10. As sand gradually falls into the bag, sleeve 14 moves upward under the elastic force of first spring 16. At this time, guide post 18 slides upward again along guide groove 17, driving sleeve 14 to drive hopper 20 to swing back and forth, thus ensuring uniform material distribution. Fill the bag to a height of 200mm above the opening, ensuring a density of ≥95%. Verification standard: the bag's edges are straight and without collapse. Then, push the adjusting ring 21 upwards to release the positioning clamp 23 from the bag opening. Fold the bag opening ≥3 times to form a sealing layer. Use anti-corrosion rope to tie the bag opening with a double flat knot, and apply elastic sealant to cover the knot. Then, control the rotary motor 11 to drive the sleeve 14 to rotate the hopper 20 180° to switch to the standby position. The excavator grabs the placement execution module 3 and geotextile bag 4 via the quick connector, and moves them to the target position at a low position, ≤0.5m above the ground. Maneuver the excavator to slide and position the geotextile bag 4 tangentially along the J-shaped curved surface. If necessary, make a slight adjustment of ±5° to assist in bag removal. After the bag is in place, apply vertical pressure (≤10kN / m) to the bottom surface of the placement execution module 3. 2 Level the top surface of the bag; then check the placement accuracy: plane position deviation ≤ 50mm, gap between adjacent bags ≤ 100mm, and flatness of the bag top ≤ 3°.

[0075] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0076] 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.
