Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a long-distance geogrid tensioning and laying device. Background Technology

[0002] Geocells are mesh-like cell structures formed by strong welding or riveting of wide strips of high-strength HDPE or PP copolymer. They are lightweight, wear-resistant, chemically stable, resistant to photo-oxidative aging, and resistant to acids and alkalis. Suitable for various soil types and desert environments, they can be used as a subbase to treat weak foundations and increase their bearing capacity, laid on slopes to form slope protection structures, and used to construct retaining structures. Geocells offer advantages such as flexibility and foldability during transportation. During construction, they need to be tensioned into a mesh shape and filled with loose materials such as gravel, soil, and concrete. However, current geocells present several problems in use: As a flexible material, geocells are folded during transport, requiring four to eight people to tension them simultaneously, which is extremely labor-intensive and inefficient. If the geocells are not tensioned during filling, deformation may occur during the filling process, affecting construction quality. Furthermore, existing geocell tensioning devices have poor versatility; one device can only be used for geocells of a specific size. Therefore, multiple tensioning devices are often needed to meet construction requirements, increasing costs. Existing technology requires matching the tensioning and laying device with a traction mechanism, limiting its application.

[0003] Existing technologies still have shortcomings in use. For example, a geocell laying device with patent number CN202011354182.4 includes tracks fixed on the left and right sides of the geocell, with several tensioning components slidably connected on the tracks. The tensioning components can slide freely along the tracks. Each tensioning component includes a detachably connected tension rod at the front end. The tension rod is vertically arranged and is used to provide tension force by passing through the geocell. When the end of the geocell is laid in a small area, it is impossible to use traction equipment to pull the device, requiring secondary manual operation, which reduces the adaptability of the device.

Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Example: Reference Figures 1-9 A long-distance geogrid tensioning and laying device includes: a mounting base 1, each of the two mounting bases 1 is provided with a vertical plate 2, a traction mechanism 5 is connected between the two mounting bases 1, the output end of the traction mechanism 5 is connected to the end of the geogrid, the other end of the geogrid is connected to an anchor rod, a slide rail 3 is provided on the vertical plate 2, a plurality of tensioning mechanisms 4 are slidably connected on the slide rail 3, each tensioning mechanism 4 is connected to the side wall of the geogrid, and a controller 6 is provided at the top of the slide rail 3, the controller 6 is connected to the tensioning mechanism 4 and the traction mechanism 5.

[0032] The working process and beneficial effects of the above technical solution are as follows:

[0033] According to the width of the geogrid to be laid, the spacing between the two mounting seats 1 is adjusted. The two mounting seats 1 are guided by the traction mechanism 5 and, after being adjusted to the specified spacing, are set parallel to each other on the roadbed. The geogrid is placed between the two mounting seats 1. One end of the geogrid is fixed by the top of multiple anchor rods set on the roadbed. The geogrid consists of a rectangular array of multiple geogrid cells. The side wall of the top of each anchor rod is attached to the inner end wall of each geogrid cell at one end of the geogrid. The other end of the geogrid is attached to the output end of the traction mechanism 5. The output end of the traction mechanism 5 provides tension to each geogrid cell at the other end of the geogrid. The output end of the traction mechanism 5 works with the anchor rods to tension the geogrid. This reduces the need for external traction equipment and avoids the situation where the traction mechanism cannot be used when the space provided for movement near the other end of the geogrid far from the anchor rod is small. It also improves the adaptability of the mechanism to the working site.

[0034] The two side walls of the geogrid are pulled by multiple tensioning mechanisms 4 slidably connected to the slide rail 3. The controller 6 provides air pressure to the cylinder of the traction mechanism 5 through the pipeline, and the output end of the traction mechanism 5 provides traction force. After the geogrid is tensioned, the multiple tensioning mechanisms 4 cooperate with the multiple geogrid cells on the two side walls of the geogrid to provide longitudinal tension to the side walls of the geogrid cells. This makes the device suitable for laying geogrids over long distances and keeps the width in the middle unchanged. At the same time, after the geogrid is tensioned to a specified distance, the controller 6 controls the tensioning mechanisms 4 to automatically lay and fix the side walls of the geogrid cells, reducing the tediousness of manual operation and improving the automation level of the device.

[0035] This invention has been implemented in the Huaihe Road, Ziyun Road, and Hangying Road road and integrated utility tunnel project in Chengnan New District of Fuyang City. This invention realizes the tensioning and laying of geogrids over long distances.

[0036] The traction mechanism 5 includes: a first cylinder 7, with a first cylinder 7 provided on the top surface of each of the two mounting seats 1; the output end sidewall of one first cylinder 7 is perpendicularly connected to one end of the sleeve 9, and the output end sidewall of the other first cylinder 7 is perpendicularly connected to one end of the insertion tube 8; both first cylinders are connected to the controller 6 through pipes; the other ends of the insertion tube 8 and the sleeve 9 are inserted and fitted together; multiple longitudinal channels penetrating the tube body are equidistantly opened on the insertion tube 8 and the sleeve 9; a traction column 10 is inserted into each channel; the geogrid is composed of a rectangular array of multiple geogrid cells; the sidewall of each traction column 10 is attached to the inner end wall of a geogrid cell; and the other ends of the two mounting seats 1 are connected by a guide assembly 11.

[0037] The working process and beneficial effects of the above technical solution are as follows:

[0038] The two mounting bases 1 are adjusted to be parallel and spaced together via the connecting tube 8, sleeve 9, and guide assembly 11. After adjusting the distance between the two mounting bases 1, a traction column 10 is inserted into the longitudinal through-channels on the tubes 8 and 9, as well as at the joints of the tubes 8 and 9. The traction column 10 can be stabilized on the tubes 8 and 9 by fitting a retaining ring on its side wall, or by setting a thread on the traction column 10 and connecting it to a nut, with the retaining ring and nut engaging to pull the traction column. The column 10 is fixed on the insertion tube 8 and the sleeve 9. The side wall of the traction column 10 is in contact with the side wall of each geocell at the end of the geocell away from the anchor rod. The controller 6 controls the two first cylinders 7 to pull the geocell synchronously. By opening longitudinal through holes at equal intervals on the insertion tube 8 and the sleeve 9, the traction column 10 is inserted into the through holes and the geocell is pulled. This ensures that the geocell is subjected to uniform lateral force and avoids the geocell from changing shape due to uneven force during long-distance laying and tensioning of the geocell, which would affect the laying effect.

[0039] The guide assembly 11 includes an auxiliary insertion tube 12 and an auxiliary sleeve 13. One end of the mounting base 1 is vertically mounted with the end of the auxiliary insertion tube 12, and the other end of the mounting base 1 is vertically mounted with the end of the auxiliary sleeve 13. The other ends of the auxiliary insertion tube 12 and the auxiliary sleeve 13 are inserted into each other.

[0040] The working process and beneficial effects of the above technical solution are as follows:

[0041] By setting auxiliary insertion tube 12 and auxiliary sleeve 13 between the two mounting seats 1, the auxiliary insertion tube 12 and auxiliary sleeve 13 can be inserted and matched with each other, so as to maintain the parallelism between the two mounting seats 1 during the spacing adjustment process, ensure the parallelism between the slide rails 3 on the mounting seats 1, and avoid the uneven lateral tension force provided by the tensioning mechanism 4 slidably connected on the slide rail 3 to the sidewall of the geogrid.

[0042] The tensioning mechanism 4 includes: a second cylinder 14, which is slidably connected to the slide rail 3 and connected to the controller 6. The output end of the second cylinder 14 facing the roadbed surface is connected to a mounting plate 15. A column shell 16 is slidably connected in the through hole of the mounting plate 15. A mounting ring 17 is fitted on the column shell 16 and connected to the bottom surface of the mounting plate 15 through a return spring.

[0043] The working process and beneficial effects of the above technical solution are as follows:

[0044] When the controller 6 starts the first cylinder 7, the output end of the first cylinder 7 extends. The output end of the first cylinder 7 drives the insertion tube 8 and the sleeve 9 to move. The traction column 10 on the insertion tube 8 and the sleeve 9 drives the end of the geogrid to move. The column shell 16 contacts the side wall of the geogrid chamber. Under the tension of the traction column 10, the column shell 16 drives the second cylinder 14 connected to the mounting plate 15 to slide along the slide rail 3. At the same time, a pair of column shells 16 provide longitudinal tension to the side wall of the geogrid chamber. During the tensioning process, each geogrid chamber is tensioned evenly to avoid deformation of the geogrid due to untimely tensioning when laying geogrid over a long distance, which would affect the laying effect.

[0045] The controller 6 controls the output end of the second cylinder 14 to move downward, and the mounting plate 15 moves downward synchronously. After the column housing 16 contacts the roadbed surface, the return spring between the mounting ring of the column housing 16 and the mounting plate 15 is compressed to prevent the bottom end of the column housing 16 from rigidly contacting the roadbed surface and damaging its surface integrity.

[0046] The side wall of the cylindrical shell 16 has a through groove, and a rack 18 is slidably connected in the through groove. A guide plate is connected to the side wall of the rack 18. The side wall of the guide plate is connected to the inner wall of the cylindrical shell 16 by a tension spring. Guide rods 19 are slidably connected in the guide holes at both ends of the guide plate. The end of each guide rod 19 is installed on the inner wall of the cylindrical shell 16. One end of the cylindrical shell 16 is connected to the unlocking component 20. The unlocking component 20 is slidably engaged with the guide plate and the side wall of the cylindrical shell 16. The other end of the unlocking component 20 is in frictional engagement with the pressure component 21. The pressure component 21 is slidably installed in the second through hole of the mounting plate 15.

[0047] The working process and beneficial effects of the above technical solution are as follows:

[0048] The second cylinder 14 drives the mounting plate 15 to move downwards. After contacting the top of the geocell, the controller 6 stops the second cylinder 14 from moving downwards. During the downward movement of the tensioning mechanism 4, the mechanism continuously fills the geocell chamber. The bottom end of the pressure component 21 on the mounting plate 15 is placed inside the geocell chamber. The bottom end of the pressure component 21 is located on the periphery of the center of the filler accumulation. As the amount of filler increases, the height of the filler increases. The increased filler lifts the bottom end of the pressure component 21. The rise of the pressure component 21 pushes the end of the unlocking component 20, which is rubbing against it, to move towards the center of the axis of the column shell 16. The movement of the unlocking component 20 unlocks it from the rack 18. Under the action of the tension spring, the rack 18 retracts along the guide rod 19 into the column shell 16. After the rack 18 retracts, the tensioning mechanism 4 stops filling the geocell chamber. This reduces the mechanical structure setup, allows for precise control of filler addition, and ensures the stability of the two side walls of the geocell.

[0049] The unlocking assembly 20 includes: an unlocking rod 22, one end of which is connected to the inner wall of the cylindrical shell 16 via a second return spring; the unlocking rod 22 is slidably engaged with the through hole of the guide plate; an unlocking ring 23 is connected to the rod body of the unlocking rod 22 located between the side wall of the guide plate and the inner wall of the cylindrical shell 16; the unlocking ring 23 is in contact with the side wall of the push plate 24; the push plate 24 is mounted on the insertion rod 25; one end of the insertion rod 25 is slidably connected to the groove in the inner wall of the cylindrical shell 16; the side wall of the push plate 24 is connected to the end wall of the groove via a third return spring; the other end of the insertion rod 25 is inserted into the slot in the side wall of the guide plate; one end of the unlocking rod 22 extending out of the cylindrical shell 16 is connected to the end of the unlocking block 26; the other end of the unlocking block 26 has a guide arc, which is in frictional engagement with the pressure assembly 21.

[0050] The working process and beneficial effects of the above technical solution are as follows:

[0051] During the upward movement of the pressure assembly 21, the pressure assembly 21 presses the unlocking block 26 into the column housing 16. The contraction of the unlocking block 26 drives the movement of the unlocking rod 22. The second return spring connected to the unlocking rod 22 is compressed. The unlocking ring 23 on the unlocking rod 22 pushes the push plate 24 on the insert rod 25 to move. The third return spring between the push plate 24 and the end of the slide groove is compressed. The insert rod 25 is dislodged from the slot on the side wall of the guide plate, and the rack 18 is unlocked. Since the elastic force of the third return spring is greater than that of the tension spring, the mechanism is prevented from prematurely unlocking due to inaccurate setting of the spring elastic force when no external force is applied, thus improving the stability of the mechanism. At the same time, the mechanism can unlock quickly, which can prevent the tensioning mechanism 4 from wasting too much material during the filling process and improve the continuity of the mechanism's operation.

[0052] During the downward movement of the pressure assembly 21, the unlocking rod 22 resets under the elastic force of the second reset spring, the unlocking ring 23 releases the push plate 24, the insertion rod 25 resets under the elastic force of the third reset spring, the end of the third reset spring is inserted into the slot on the side wall of the guide plate, the rack 18 resets, and the mechanism prepares for the next movement after resetting, thus improving the mechanism's ability to work in cycles.

[0053] The pressure assembly 21 includes a paddle wheel 27 and a conical column 28. The mounting column is slidably connected in the second through hole of the mounting plate 15. The bottom end of the mounting column is rotatably connected to the top end of the mounting frame. The paddle wheel 27 is rotatably connected to the mounting frame. The conical column 28 is fitted on the side wall of the mounting column. The bottom end of the conical column 28 is connected to the top surface of the mounting plate 15 through a fifth return spring. The diameter of the bottom end of the conical column 28 is larger than the diameter of its top end. The side wall of the conical column 28 is in frictional engagement with the side wall of the guide arc.

[0054] The working process and beneficial effects of the above technical solution are as follows:

[0055] During the filling process of the tensioning mechanism 4, the material has fluidity. The paddle wheel 27 is located near the filling output end of the tensioning mechanism 4. When the mechanism is filling, the material accumulates from low to high in the middle of the geocell. The side wall of the paddle blade on the paddle wheel 27 rotates due to the pressure of the material. At the same time, the end wall of the paddle blade rubs and squeezes the material, generating an upward thrust on the installation column. Meanwhile, the paddle wheel 27 can adapt to filling materials of various particle sizes, preventing the paddle wheel 27 from jamming and unable to rotate. The installation column is rotatably connected to the mounting frame that connects to the paddle wheel 27. The paddle wheel 27 can change direction according to the actual flow direction of the material, preventing the mechanism from jamming and preventing the installation column from rising.

[0056] During the ascent of the mounting column, the tapered column 28, which is coaxially mounted with the mounting column, can engage with the guide arc sidewall at the end of the unlocking block 26 due to the larger diameter of its bottom end than its top end, thus reducing the need for mechanical structures.

[0057] The tensioning mechanism 4 further includes an unloading assembly 29, which includes a housing 30. The top surface of the mounting plate 15 is connected to the side wall of the housing 30. The other side wall of the housing 30 has an opening facing the geocell. The two inner walls of the housing 30 are slidably connected with toothed plates 31. The toothed plates 31 cooperate with the bottom wall of the housing 30 to seal the opening. The toothed plates 31 mesh with columnar teeth 33 for transmission. The gears 32 and columnar teeth 33 are mounted on a rotating shaft. The rotating shaft is rotatably connected to the mounting plate 15. The gears 32 mesh with a rack 18 for transmission.

[0058] The working process and beneficial effects of the above technical solution are as follows:

[0059] During the upward movement of the column shell 16 relative to the mounting plate 15, the column shell 16 drives the rack 18 to move upward synchronously. The rack 18 meshes with the gear 32, and the gear 32 rotates counterclockwise. The column tooth 33 rotates counterclockwise, and the tooth plate 31 meshing with the column tooth 33 slides upward inside the shell 30. The opening at the end of the shell 30 is opened, and the filler enters the geocell chamber through the opening, thus optimizing the transmission effect.

[0060] One end of the rotating shaft is connected to a torsion spring 34, and the other end of the torsion spring 34 is connected to the upper surface of the mounting plate 15 through a connecting plate 35.

[0061] The working process and beneficial effects of the above technical solution are as follows:

[0062] When filling the geocells, the rack 18 meshes with the gear 32, causing the shaft to rotate and the torsion spring 34 to store energy. When the geocells are filled, the pressure component 21 pushes the unlocking component 20 to unlock the rack 18, and the gear 32 retracts into the cylindrical shell 16. After the gear 32 loses its limit, the shaft releases its elastic potential energy and resets through the torsion spring 34. During the reset process, the cylindrical gear 33 drives the toothed plate 31 to move downward, closing the opening of the shell 30 to avoid waste of filler and optimizing the cyclic operation function of the mechanism.

[0063] The bottom two ends of the mounting plate 15 are connected to a pressure plate by compression springs. Each pressure plate has a first contact 36 on its upper surface. The first contact 36 and the second contact 37 are in contact and cooperate. The second contact 37 is fixed to the bottom surface of the mounting plate 15. The first contact 36 and the second contact 37 are electrically connected to the controller 6.

[0064] The working process and beneficial effects of the above technical solution are as follows:

[0065] When the controller 6 controls the second cylinder 14 to push the mounting plate 15 downward, the column shell 16 on the mounting plate 15 first contacts the roadbed surface. The second cylinder 14 continues to push the mounting plate 15 downward until the pressure plate at its bottom end fits against the top of the geocell. The spring between the pressure plate and the mounting plate 15 is compressed, and the first contact 36 and the second contact 37 make contact and engage. Since the first contact 36 and the second contact 37 are in contact and engaged with the controller 6, the controller 6 receives the electrical signal that the two contacts are connected, closes the second cylinder 14, and stops the mounting plate 15 from continuing to move downward, preventing the top of the geocell from being crushed by the continuously applied pressure and maintaining the integrity of the geocell.

They can be applied to various fields suitable for the present invention. Other modifications can be easily made by those skilled in the art.
