Description

Technical Field

[0001] This invention belongs to the field of slope protection technology, and specifically relates to a geocell retaining wall filler spreading and leveling device and spreading and leveling method. Background Technology

[0002] Geocells are a three-dimensional mesh-like constrained structure with advantages such as high strength, good integrity, and strong ecological compatibility. They are currently widely used in highway slope protection projects. Highway slopes have significant standardized characteristics. After professional design and mechanized construction, the slope surface is flat and standardized, the slope is uniform, the geocell dimensions are consistent, and the length of a single slope can typically reach hundreds of meters.

[0003] Currently, the filling of geocells on most highway slopes in China is carried out using a combination of excavators and manual labor: the excavator directly shovels and piles the soil on top of the unfolded geocells, and then the backfilling is completed by swinging the boom and pressing down.

[0004] However, this method of operation has many problems: the soil falling point of the excavator is uneven, which can easily cause the geocells to be incompletely filled; when the excavator bucket presses down, it can easily damage the welding points and side walls of the geocells, causing the geocells to deform, crack or even fail, requiring a lot of rework later, which not only affects the overall construction efficiency, but also increases labor costs. Summary of the Invention

[0005] In view of the above analysis, the present invention aims to provide a geocell retaining wall filling material spreading and leveling device and method to solve one or more of the above-mentioned problems existing in the prior art.

[0006] The objective of this invention is achieved as follows: On the one hand, a geocell retaining wall fill material spreading and leveling device is provided, comprising: Two parallel transverse tracks are located at the top and bottom of the slope, respectively. The frame is movably mounted on the transverse track, with one end located at the top of the slope and the other end located at the bottom of the slope. The material bin is movably mounted on the frame and can move longitudinally and laterally along the slope. The bottom and top of the material bin are open. A gate mechanism, located at the bottom of the material box, is capable of opening the material box to allow the filler to fall. The feeding mechanism, located on the transverse track, is capable of continuously feeding the material box.

[0007] Furthermore, the transverse track is erected off the ground by laying a foundation or installing supports.

[0008] Furthermore, the feeding mechanism includes a feeding frame, a feeding drive device, a feeding platform, and a discharge head. The feeding frame is movably connected to the transverse track, the feeding drive device is drivenly connected to the feeding frame, the feeding platform is movably connected to the feeding frame, and the discharge head is connected to the feeding platform to deliver the filler.

[0009] Furthermore, the feeding mechanism also includes a feeding pipe structure, one end of which is connected to the discharge head, and the other end is located at the bottom or top of the slope. The feeding pipe structure can draw in the filler and send it out through the discharge head.

[0010] Furthermore, the feeding rack can move with the frame, and the feeding platform can move accordingly with the longitudinal position of the material box on the slope, so that the material box can move below the discharge head to receive the filling material.

[0011] Furthermore, it also includes a main frame, a first driving device, and a second driving device. The main frame is movably connected to one longitudinal side of the frame. The first driving device is driven to the main frame and is used to drive the main frame to move along the longitudinal side of the frame. The second driving device is mounted on the main frame. The material box is driven to the second driving device and is used to drive the material box to move along the transverse direction of the frame.

[0012] Furthermore, the gate mechanism includes a draw plate that is slidably connected to the bottom of the hopper, and the draw plate can open the hopper by sliding and pulling it out.

[0013] Furthermore, the gate mechanism also includes a winding machine and a reversing frame. The reversing frame is connected to the side of the material box opposite to the feeding platform and extends away from the material box. The winding machine is located in the middle of the side of the material box and is on the same side as the reversing frame. The rope wound by the winding machine is reversed by the reversing frame, extends horizontally, and is connected to the side of the draw plate.

[0014] Furthermore, the gate mechanism also includes a locking mechanism located at the opposite end of the winding machine, which is used to drive the pull plate to reset.

[0015] Furthermore, the material box is also equipped with a paving auger and a third driving device. The paving auger can rotate and evenly disperse the filler material piled in the material box. The third driving device is located on the top side of the material box and can drive the paving auger to move in the lateral direction of the material box.

[0016] Furthermore, it also includes an anti-tilting mechanism, which is used to abut against the side walls of the two rows of geocells below the lateral sides of the material box before the material is discharged from the material box, so as to prevent the geocells from tilting during the filling process.

[0017] On the other hand, a method for spreading and leveling geocell retaining wall fill material is also provided, using the above-mentioned geocell retaining wall fill material spreading and leveling device. The method includes the following steps: The drive frame slides along the transverse track to the transverse position corresponding to the first area to be filled on the slope; then the material box is adjusted so that it moves longitudinally and laterally along the frame, and the material box is moved to the position directly below the discharge port of the feeding mechanism to complete the alignment of the receiving position; Start the feeding mechanism, which continuously feeds filler into the top-opening hopper. The filler accumulates inside the hopper, forming a uniformly spread material layer. After the material box is prepared, drive the material box to move laterally again, so that the entire material box is moved to a position directly above the target geocell array on the slope and then fixed in place, ensuring that the projection range of the material box completely covers the geocell area to be filled. Activate the gate mechanism at the bottom of the material box to open the bottom opening; the entire material layer inside the material box falls vertically to fill the geocell below, completing the filling operation for a single area; After the filling of a single area is completed, the material box is moved laterally to the next adjacent area to be filled, and the filling of each row and column of geocells on the slope is completed area by area; The work is carried out in a continuous cycle from top to bottom and from one side to the other. Relying on the multi-directional movement capability of the frame and the material box, the various work areas are seamlessly connected until all geocells on the entire slope are filled and the construction is completed.

[0018] Compared with the prior art, the geocell retaining wall filling material spreading and leveling device and spreading and leveling method provided by the present invention can achieve at least one of the following beneficial effects: 1. Utilizing transverse tracks and frames erected at the top and bottom of the slope, along with material boxes that can move longitudinally and laterally along the slope, the material boxes can flexibly cover the entire slope working surface. The filling points can be freely adjusted according to the placement of the geocells, making it suitable for long-distance, standardized slope construction conditions on highways. It features a wide operating range and strong site adaptability. Furthermore, when the material box moves as a whole, it drops the material onto the geocells, eliminating the repetitive steps of manual spreading of fill material and eliminating the need for construction personnel to enter the slope working surface to fill each geocell individually, significantly reducing the safety risks of slope construction. Simultaneously, the overall material dropping method ensures uniform filling of each geocell, resulting in faster filling speed and significantly higher work efficiency than traditional manual filling operations. It can meet the construction needs of large-area slope geocell retaining walls, reducing construction labor costs and improving the overall construction quality and safety.

[0019] 2. The feeding mechanism enables automated continuous feeding, and the gate mechanism at the bottom of the material box completes the unloading. The entire filling process does not require an excavator to perform bucket feeding, boom swinging and pressing operations, which avoids squeezing and impacting the geocell body and welding points. It also avoids the problems of geocell sidewall deformation, welding point cracking and even overall failure from the root, reduces the amount of rework in the later stage, and ensures the integrity and service strength of the geocell three-dimensional mesh constraint structure.

[0025] A specific embodiment of the present invention discloses a geocell retaining wall fill material spreading and leveling device, hereinafter referred to as a "spreading and leveling device". Figures 1 to 9 As shown, the paving and leveling device includes a transverse track 100, a frame 101, a material box 20, a gate mechanism 400, and a feeding mechanism 300. Two parallel transverse tracks 100 are respectively located at the top and bottom of the slope 11. The frame 101 is movably mounted on the transverse tracks 100, with one end at the top of the slope 11 and the other end at the bottom. The material box 20 is movably mounted on the frame 101 and can move longitudinally and laterally along the slope 11. The bottom and top of the material box 20 are open. The gate mechanism 400 is located at the bottom of the material box 20 and can open the material box 20 to allow the filler to fall. The feeding mechanism 300 is located on the transverse track 100 and can continuously feed material to the material box 20.

[0026] During implementation, a transverse track 100 is first laid at the top and bottom of slope 11. The frame 101, arranged across the slope, is movably installed on the transverse track 100, allowing the frame 101 to move laterally along slope 11. The material box 20 can move freely longitudinally and laterally along the frame 101, reaching any geocell placement position on slope 11. The feeding mechanism 300 continuously delivers filler to the material box 20, forming a flat material layer within the box. Once the material box 20 has moved above the target geocell and completed its positioning, the gate mechanism 400 opens the bottom of the material box 20, allowing the filler inside to fall, completing the geocell filling operation. Through the cross-slope frame 101 and the movable material box 20, the entire working surface of slope 11 can be covered, perfectly adapting to the long-distance and standardized slope construction conditions of highways, with no blind spots in the work area.

[0027] In this embodiment, the transverse track 100 is erected off the ground by laying a foundation or installing supports. The transverse track 100 is not laid directly on the surface of the slope 11, but is suspended at a certain distance from the slope surface in the above manner. This can effectively prevent the transverse track 100 from sinking due to the soft soil on the slope, ensuring the stability and positioning accuracy of the frame 101 and the material box 20. It can also adapt to the uneven terrain of the slope, improve the site adaptability of the device. Even if the slope 11 has problems such as undulation, uneven height or lateral bending, it can be solved by this method, while keeping the overall equipment neat.

[0028] Typically, this embodiment can be adapted to geocells of different shapes, such as rectangular, rhomboid, and triangular, depending on the actual operating conditions. In the exemplary setting, the material box 20 adopts a rectangular structure, which is preferentially adapted to rectangular geocells.

[0029] For the filling operation of rectangular geocells, the outline of the rectangular material box 20 matches the array layout of the rectangular geocells. After the material box 20 is aligned, it can cover multiple rectangular cells at one time. After the equipment automatically distributes and spreads the material evenly inside, a relatively flat overall material layer will be formed inside the material box 20. Then, by instantaneously pulling out and unloading the material, the large area of ​​filler material falls vertically and fills all the rectangular geocells within the operation range at the same time. Each cell is filled evenly, and the molding consistency of batch filling in a single area is high.

[0030] For filling diamond-shaped geocells, the large rectangular material box 20 can completely cover the irregular contour area composed of multiple diamond-shaped geocells in one go. However, for the edge areas of irregular geocells, the rectangular material box 20 cannot completely correspond to the edge geocells, resulting in insufficient filling of the edge geocells in one go. Therefore, after the filling of a single area is completed, the equipment relies on the transverse rails 100 at the upper and lower ends of the slope 11 and the cross-slope frame 101 to complete the overall transverse displacement, so that the side of the rectangular material box 20 accurately fits the edge position of the previous operation area. While completing the overall filling operation of the current new area, the equipment uses the coverage of the material box 20 to fill the gaps at the edges of the irregular geocells and the sharp corners left over from the previous operation, gradually filling all the local unfilled positions. Through this complementary filling operation logic of adjacent work stations, the equipment does not need to be adapted to the structure of the special irregular material box 20. It can complete the filling operation of all irregular geocell edges and sharp corners one by one by relying solely on the segmented, fitting, and progressive construction of the rectangular material box 20.

[0031] After the batch filling of a single slope area is completed, the equipment relies on the transverse rails 100 at the top and bottom of the slope 11 and the cross-slope frame 101 to complete the overall transverse displacement. At the same time, the material box 20 is adjusted longitudinally and laterally along the frame 101. The filling operation of each unit area is completed by continuously filling area by area and row by row. The filling areas are connected in an orderly manner, and the entire slope 11 working surface is gradually and neatly expanded and seamlessly covered.

[0032] In some optional embodiments, the feeding mechanism 300 includes a feeding frame 301, a feeding drive device, a feeding platform 303, a feeding pipe structure 304, and a discharge head 302. The feeding frame 301 is movably connected to the transverse track 100. The feeding drive device is drivenly connected to the feeding frame 301. The feeding platform 303 is movably connected to the feeding frame 301. The discharge head 302 is connected to the feeding platform 303. One end of the feeding pipe structure 304 is connected to the discharge head 302, and the other end is set at the bottom or top of the ramp 11. The feeding pipe structure 304 can draw in the filler and send it out through the discharge head 302.

[0033] The feeding rack 301 can move along the transverse track 100, and the feeding platform 303 can move along the feeding rack 301. The feeding pipe structure 304 continuously pumps the filler from the bottom or top of the ramp 11 to the discharge head 302, which then evenly feeds the filler into the material box 20 below. The feeding rack 301 can move with the frame 101, and the feeding platform 303 can move accordingly to follow the longitudinal position of the material box 20 on the ramp 11, so that the material box 20 can move below the discharge head 302 to receive the filler.

[0034] During operation, the feeding frame 301 moves laterally in sync with the frame 101, ensuring that the feeding mechanism 300 and the frame 101 maintain consistent working positions. The feeding platform 303 can move in real time according to the longitudinal position of the material box 20, ensuring that the discharge head 302 is always dynamically aligned with the receiving range of the material box 20, achieving alignment without deviation throughout the process. The material box 20 can move towards the feeding platform 303, eventually reaching the receiving position and stopping below the discharge head 302 to receive the fill material. The fill material is continuously drawn and transported from the top or bottom of the slope via the feeding pipe structure 304, and then falls evenly through the discharge head 302 into the rectangular material box 20 below. During the receiving process, the material box 20, in conjunction with the internal spreading auger 25, moves laterally to spread the accumulated fill material evenly, forming a uniform and flat material layer inside the material box 20. After a single receiving operation, the material box 20 leaves the feeding area and moves above the geocell to perform unloading and filling operations. After the same transverse batch of geocell filling on slope 11 is completed, the material box 20 moves down slope 11 to the next working area, and the feeding mechanism 300 continues to follow and move, so as to realize continuous and uninterrupted material receiving and filling cycle operation on the slope.

[0035] In this embodiment, the feeding pipe uses a flexible hose. A drive motor is mounted on the outside of the hose's inlet end, and the motor is connected to a drive shaft that runs through the hose. Spiral auger blades are fixed on the drive shaft. The material is pushed by the auger driven by the external motor. The discharge head 302 uses an existing telescopic feed head. The feeding rack 301 can move along the transverse track 100, and the feeding platform 303 can move along the feeding rack 301. The inlet motor runs continuously, driving the auger inside the hose to rotate, conveying the filler from the bottom or top of the ramp 11 to the discharge head 302 manually or by other means. During the feeding operation, the telescopic feed head's hopper 20 extends, reaching the area above the hopper 20 to complete the feeding; after feeding, the telescopic feed head retracts.

[0036] Optionally, the feeding drive device adopts a lead screw linear drive structure. This structure is encased in a protective shell, with the slider exposed through an opening at the bottom of the protective shell and connected to the feeding platform 303, thereby driving the feeding platform 303 to move. Alternatively, the feeding drive device uses a winding machine 401 to wind a rope to drive the feeding platform 303 to move. The winding machine 401 is located at one end of the feeding frame 301. The above-mentioned lead screw linear drive structures are all existing structures, and other types of drive structures can also be selected.

[0037] In some alternative embodiments, the material distribution box 20 distributes material gradually downwards from the top of the slope 11 towards the bottom. This arrangement allows excess material to fall into the geocells of the next filling area, reducing material waste.

[0038] In this embodiment, the paving and leveling device further includes a main frame 21, a first driving device 22, and a second driving device 23. The main frame 21 is movably connected to one longitudinal side of the frame 101. The first driving device 22 is driven to connect with the main frame 21 and is used to drive the main frame 21 to move along the longitudinal side of the frame 101. The second driving device 23 is mounted on the main frame 21. The material box 20 is driven to connect with the second driving device 23 and is used to drive the material box 20 to move along the transverse direction of the frame 101.

[0039] An auxiliary frame 24 is also provided on the other side of the frame 101, corresponding to the main frame 21. The other end of the second drive device 23 can be connected to the auxiliary frame 24 for auxiliary support.

[0040] During operation, the material box 20 can move longitudinally and laterally through the driving cooperation of the first driving device 22 and the second driving device 23, and the material box 20 can also stop below the feeding mechanism 300 to complete the receiving of materials.

[0041] A longitudinal lead screw is arranged parallel to the longitudinal side of frame 101, with both ends of the lead screw rotatably supported at the ends of frame 101. The drive motor of the first drive device 22 is fixed at the end of frame 101, and the motor output shaft is coaxially connected to the longitudinal lead screw. A lead screw nut seat is fixed at the bottom of the main frame 21, and the nut seat forms a threaded engagement with the longitudinal lead screw. During operation, the motor drives the lead screw to rotate, and the threaded transmission pair drives the nut seat and the main frame 21 as a whole to perform linear reciprocating motion along the longitudinal direction of frame 101. A transversely arranged lead screw is mounted on the main frame 21; a second drive motor is mounted on the main frame 21, and its output shaft is connected to the transverse lead screw. A lead screw nut seat is fixed at the bottom or side of the material box 20, and the nut seat is fitted onto the transverse lead screw to form a threaded engagement. The drive structure of the first drive device 22 and the second drive device 23 also adopts the existing structure, and their connection with the main frame 21 and the material box 20 can use the existing settings. The first drive device 22 and the second drive device 23 can also be a combination of a winding machine 401 and a rope.

[0042] In some alternative embodiments, the gate mechanism 400 includes a pull plate 403 slidably connected to the bottom of the material box 20, and the pull plate 403 can open the material box by translating and pulling it out. Specifically, the gate mechanism 400 includes a winding machine 401, a reversing frame 402, and a pull plate 403. The pull plate 403 is slidably connected to the bottom of the material box 20. The reversing frame 402 is connected to one side of the material box 20 opposite to the feeding platform 303 and extends away from the material box 20. The winding machine 401 is located in the middle of the side of the material box 20 and is on the same side as the reversing frame 402. The rope wound by the winding machine 401 is reversed by the reversing frame 402, extends horizontally, and is connected to the side of the pull plate 403.

[0043] Optionally, the gate mechanism 400 further includes a locking mechanism 404, which is located at the opposite end of the winding machine and is used to drive the pull plate 403 to reset. For example, the locking mechanism 404 includes a locking winding device, which has the same structure as the winding machine 401 but with lower power and structure. It is positioned opposite the winding machine 401, and the locking winding device synchronously releases wire when the winding machine 401 releases wire. The locking winding device can drive the pull plate 403 to reset via a rope.

[0044] During the unloading operation, the winding machine 401 quickly winds up the wire rope, and the guide frame 402 pulls the pull plate 403 to quickly move and pull it away, so that the bottom of the material box 20 can be opened horizontally in a very short time.

[0045] The adoption of a sliding extraction gate opening method allows the filling material inside the box to fall synchronously as a whole, effectively solving the problems of incomplete cell filling and inconsistent filling quality caused by uneven soil landing points in traditional construction methods; the 300 feeding mechanism ensures the continuity of operation, eliminates the dependence on manual auxiliary operation, and improves construction efficiency and standardization.

[0046] In one alternative embodiment, the reversing frame 402 includes a reversing plate and a reversing shaft. The reversing plate is connected to the side edge of the hopper 20 and extends outward. The reversing shaft is connected to the far end of the reversing plate, and the wire rope extends horizontally through the reversing shaft.

[0047] In this embodiment, the gate mechanism adopts a reversing traction structure of a winding machine 401 and a reversing frame 402, converting the vertical winding power of the winding machine 401 into the horizontal translational force of the pull plate 403. The winding machine 401 includes a motor and a winding wheel, and the motor can drive the winding wheel to rotate and wind up the wire. The winding machine 401 is equipped with a protective sleeve, through which the rope passes. One end of the pull plate 403 can be moved from one end of the material box 20 to the other end, realizing the full opening of the bottom opening of the material box 20 without any residue. An extension support wheel can also be installed on the outside of the material box 20, located on the moving path of the pull plate 403, to support the pulled plate 403.

[0048] It should be noted that when opening the material box 20 to release material, the withdrawal speed of the gate mechanism 400 pull plate 403 should be as fast as possible. The purpose is to ensure that the gate is completely withdrawn from the bottom of the material box 20 before the filling material undergoes significant horizontal displacement. This ensures that all the filling material inside the box loses support almost simultaneously within a very short time, allowing the filling material to fall as evenly and synchronously as possible. This reduces or even avoids situations where some parts fall first and others fall later, ensuring that the filling amount and filling density of each geocell are roughly the same. At the same time, it also minimizes the probability of the filling material being driven by the gate to undergo horizontal displacement, avoiding problems such as missing material at the corners of the geocells and uneven edges, thus improving the filling and molding quality. It is understood that in this embodiment, the gate mechanism 400 can also adopt other structural forms in the prior art, as long as the requirement of minimizing the opening time is met.

[0049] In some alternative embodiments, the material box 20 is also provided with a paving auger 25 and a third drive device 26. The paving auger 25 can rotate and evenly disperse the filler material piled in the material box 20. The third drive device 26 is located on the top side of the material box 20 and can drive the paving auger 25 to move in the lateral direction of the material box 20.

[0050] The material hopper 20 is equipped with a paving auger 25 and a third drive device 26. The third drive device 26 is located on the top side of the material hopper 20 and can drive the paving auger 25 to move back and forth laterally along the material hopper 20, while the paving auger 25 itself rotates. During the process of receiving material from the feeding mechanism 300, the filler material is prone to uneven distribution, with some accumulating in the middle and less on both sides. At this time, the third drive device 26 drives the rotating paving auger 25 to sweep laterally along the entire length of the material hopper 20, spreading and evenly dispersing the locally accumulated filler material to both sides, thus leveling the material layer inside the material hopper 20. Through the dynamically moving paving and evenly distributing structure, the thickness of the filler material inside the material hopper 20 can be made uniform throughout.

[0051] Optionally, the paving auger 25 includes a roller and counter-rotating blades extending laterally, with the roller connected to a drive motor. The third drive unit 26 is a lead screw linear module mounted on the top side of the hopper 20. The third drive unit 26 may also employ other existing structures.

[0052] In this embodiment, the paving and leveling device also includes an anti-tilting mechanism, which is used to abut against the side walls of the two rows of geocells below the lateral sides of the material box 20 before the material box 20 is filled, so as to prevent the geocells from tilting during the filling process.

[0053] Before the material box 20 is moved and aligned and before the unloading operation begins, the anti-tilting mechanism extends and abuts against the outer walls of the two rows of geocells arranged on the lower sides of the material box 20, forming a two-way lateral constraint support for the geocells at the edge of the working area.

[0054] Geocells are hollow, thin-walled mesh structures. After filling, due to the slope inclination of slope 11, the fill material inside the geocell will be compressed against the sidewalls under gravity, which can easily lead to lateral displacement, tilting, or misalignment of the geocell. By using an anti-tilting mechanism to hold and fix the sidewalls of the geocell in advance, the tilting deformation of the geocell can be effectively limited, reducing the occurrence of tilting or skewing after the geocell filling is completed.

[0055] In one alternative embodiment, the anti-tilt mechanism includes two sets of alternating support arm structures, each of which includes a fourth drive device 50, a lifting member 51, a horizontal member 52, a lifting motor 53, a rotating platform 54, a rotating sleeve 55, a rotating motor 56, and a support plate 57.

[0056] Two sets of alternating support arm structures are respectively located on the longitudinal sides of opposite sides of the frame 101, with one set located above the material box 20 and the other set located below the material box 20.

[0057] The fourth drive device 50 is connected to the outer side of the longitudinal side of the frame 101. The fourth drive device 50 adopts a lead screw linear drive structure. The fourth drive device 50 is driven to connect with the lifting member 51. The fourth drive device 50 drives the lifting member 51 to move longitudinally along the longitudinal side of the frame 101 along the slope 11. The lifting member 51 is located outside the auxiliary frame 24 or the main frame 21. The two do not interfere with each other when they move relative to each other.

[0058] The horizontal component 52 and the lifting component 51 are rotatably connected via a rotating shaft. They rotate relative to each other using a rotating structure and a rotating motor. Multiple lifting motors 53 are evenly distributed on the horizontal component 52, which extends to the opposite end of the frame 101. The lifting motors 53 are positioned downwards, with their drive shafts extending downwards through the central groove of the horizontal component 52. A rotating platform 54 is connected to the drive shaft, and a rotating sleeve 55 is fitted onto the rotating platform 54, rotatably connected to it. The bottom of the rotating platform 54 has a boss that rotatably engages with a groove on the inner wall of the rotating sleeve 55. A rotating motor 56 is mounted on the top surface of the rotating platform 54, driving a gear that meshes with the tooth groove on the inner wall of the rotating sleeve 55. An annular protective cover is provided in the gap between the boss and the top of the rotating sleeve 55. A support plate 57 is connected to the bottom surface of the rotating sleeve 55. The spacing of the support plates 57 is set according to the spacing of the geocells.

[0059] To increase the adaptability of the support, a geocell is provided with two support plates 57. The two support plates 57 support one side of a rectangular geocell, or the two support plates 57 support the opposite two sides of a rhombic geocell.

[0060] During operation, the abutment plate 57 of the alternating support arm structure above the material box 20 first moves to the outer wall of the geocell at the upper edge of the predetermined area to provide support. The abutment plate 57 below the material box 20 then moves to abut the outer wall of the geocell at the lower edge of the predetermined area, forming support in the vertical direction of the predetermined area. Subsequently, the material box 20 is controlled to lay material. After laying one transverse area of ​​the slope 11, the feeding platform 303 resets or moves away from the vicinity of the frame 101. The horizontal member 52 of the alternating support arm structure above the material box 20 rotates and rises, then moves downwards to the outer wall of the geocell at the lower edge of the next laying area. The other abutment plate 57 at the lower edge of the original laying area remains in place. When the next laying area is used for geocell laying, the relative position of this abutment plate 57 automatically changes to support the geocell at the upper edge of the next laying area. When the abutment plate 57 abuts the geocell, it can abut against either the inner or outer wall of the geocell, thus serving as a material stopper. All components of the anti-tilting mechanism and the material box 20 operate normally and do not interfere with each other during operation. There is a reserved clearance between the material box 20 and the horizontal component 52.

[0061] In this embodiment, the paving and leveling device adopts a sequential material distribution operation from the top to the bottom of the slope 11. Slightly excess filler can be placed in the upper area, allowing it to flow naturally along the slope under its own weight, filling any missing material or gaps in the geocells below, ultimately compensating for errors and further improving the overall filling fullness. Alternatively, after construction is completed, material can be manually spread from the top of the slope for automatic or on-demand replenishment. This step optimizes the construction effect and makes the geocell layout more neat.

[0062] This embodiment also provides a method for spreading and leveling geocell retaining wall fill material, using the aforementioned geocell retaining wall fill material spreading and leveling device; the method includes the following steps: The drive frame 101 slides along the transverse track 100 to the transverse position corresponding to the first area to be filled on the ramp 11; then the material box 20 is adjusted so that the material box 20 moves longitudinally and laterally along the frame 101, and the material box 20 is moved to the position directly below the discharge port of the feeding mechanism 300 to complete the alignment of the receiving position. Start the feeding mechanism 300, which continuously feeds filler into the top open hopper 20. The filler accumulates inside the hopper 20 and forms a uniformly spread material layer. After the material box 20 is prepared, drive the material box 20 to move laterally again, so that the material box 20 is moved as a whole to be directly above the target geocell array on the slope and fixed in position, ensuring that the projection range of the material box 20 completely covers the geocell area to be filled. Activate the gate mechanism 400 at the bottom of the material box 20 to open the bottom opening of the material box 20; the entire material layer inside the material box 20 falls vertically and fills the geocell below, completing the filling operation of a single area; After the filling of a single area is completed, the material box 20 is displaced laterally, moving from far to near or from near to far to the next adjacent area to be filled, and the filling of each row and column of geocells on the slope 11 is completed area by area; The work is carried out in a continuous cycle from top to bottom and from one side to the other. The multi-directional movement capability of the frame 101 and the material box 20 is used to make the various work areas seamlessly connected until all the geocells on the entire slope 11 are filled and the construction is completed.

[0063] Compared with the prior art, the geocell retaining wall filler spreading and leveling device and spreading and leveling method provided in this embodiment can achieve at least one of the following beneficial effects: 1. With the transverse track and the frame erected at the top and bottom of the slope, and the material box that can move longitudinally and laterally along the slope, it can flexibly cover the entire slope working surface. The filling point can be freely adjusted according to the geocell laying position, which is suitable for the long-distance and standardized slope construction conditions of highways. It has a wide operating coverage and strong site adaptability.

[0064] 2. The feeding mechanism achieves automated continuous feeding, and works with the gate mechanism at the bottom of the material box to complete the unloading. The entire filling process does not require the excavator bucket to feed, swing arm and press down, avoiding the situation of squeezing and impacting the geocell body and welding points. This avoids the problems of geocell sidewall deformation, welding point cracking and even overall failure, reduces the amount of rework in the later stage, and ensures the integrity and service strength of the geocell three-dimensional mesh constraint structure.

[0065] 3. The gate is opened by sliding and pulling at the bottom of the material box. Compared with the traditional method of excavator randomly throwing material and partially unloading material, the filling material in the box can fall synchronously as a whole. This effectively solves the problem of incomplete filling of the cells and uneven filling quality caused by uneven bucket landing points in traditional construction, and achieves uniform filling and regular structural formation.

[0066] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
