Description

Technical Field

[0001] This utility model relates to the field of geotextile laying, specifically to a road geotextile laying device. Background Technology

[0002] Geotextiles play a variety of important roles in road engineering. Lay beneath asphalt surface layers, geotextiles possess high compressive strength and good ductility to improve project quality and extend service life. In road construction, geotextiles are mainly used for isolation, drainage, filtration, and reinforcement, effectively preventing the mixing of subgrade and base materials and improving the overall stability of the road structure.

[0003] Existing geotextile laying methods have many shortcomings: First, traditional manual laying methods require multiple workers to work together, which is not only labor-intensive and inefficient, but also makes it difficult to maintain the straightness and uniformity of the laying over long distances; Second, when laying geotextile overlaps, due to the lack of precise guiding devices, it is difficult for workers to accurately control the width of the overlap area, resulting in uneven overlaps, which affects the waterproofing effect and the overall construction quality. Utility Model Content

Support shafts that can move up and down are supported inside the frame sleeves on both sides. The support shafts support geotextile rolls. An L-shaped guide rod is installed at the front end of one side of the frame sleeve. The L-shaped guide rod is provided with a guide mechanism that can press down and adjust the width of the geotextile overlap area.

[0007] Furthermore, this application also proposes that limiting sleeves and lock nuts are provided on both sides of the support shaft to restrict the movement of the geotextile roll. The limiting sleeves and lock nuts are located inside and outside the frame sleeve, and the limiting sleeves are fixed to the support shaft by locking screws.

[0008] Furthermore, this application also proposes that the guiding mechanism includes a support rod slidably connected to the crossbar of the L-shaped guide rod, a rotating rod rotatably connected to the support rod, an indicator wheel installed at the lower part of the rotating rod, and the tail of the rotating rod connected to the support rod by a compression spring.

[0009] Furthermore, this application also proposes that one end of the support rod is slidably connected to the L-shaped guide rod via a sliding sleeve, and a locking screw is provided on the sliding sleeve.

[0010] Furthermore, this application also proposes that the support rod has a rotating hole, and a rotating disk is selected and supported in the rotating hole, with the rotating disk and the rotating rod being integrally set.

[0011] Furthermore, this application also proposes that the support frame has an opening at the front end and that the rear end of the support frame is equipped with a lug plate that can be connected to a loader.

[0012] Compared with existing technologies, the advantages of this utility model are: by using a support frame, a frame sleeve, a support shaft and a guiding mechanism in combination, this utility model realizes the mechanized laying of geotextiles, solves the problems of low efficiency and poor quality of manual laying, and has the advantages of improving laying efficiency, ensuring laying quality, being easy to adjust and operate.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1-2 As shown, this application proposes a road geotextile laying device, including a support frame and frame sleeves fixed at both ends. Support shafts that can move up and down are supported inside the frame sleeves on both sides. The support shafts support geotextile rolls. An L-shaped guide rod is installed at the front end of one side of the frame sleeve. The L-shaped guide rod is provided with a guide mechanism that can press down and adjust the width of the geotextile overlap area.

[0019] The support frame can be welded from rectangular steel pipes, with frame sleeves fixed to both ends of the support frame by bolts. The support shaft is secured at both ends with double nuts. The frame sleeves allow the support shaft to move up and down to adjust its height, ensuring that the geotextile roll is always at the bottom, close to the ground, against its own weight. The geotextile roll is sleeved on the support shaft, and the geotextile is unrolled by rotating the support shaft. The vertical rod of the L-shaped guide rod is fixed to the front end of the frame sleeve, and the horizontal rod bends forward and extends parallel to the front end of the geotextile roll. The guiding mechanism is installed on the horizontal rod and controls the overlap width by pressing down on the edges of adjacent laid geotextile.

[0020] This device replaces manual laying with a mechanical structure, solving the problems of low efficiency and difficulty in controlling the overlap width in existing technologies. The support frame and frame sleeve form a stable support, and the support shaft is height-adjustable to adapt to different working conditions. The guiding mechanism can precisely control the geotextile overlap width, ensuring laying quality. Compared to manual laying, this device is easier to operate, significantly improves laying efficiency, and guarantees a consistent overlap width.

[0021] Furthermore, this application also proposes that limiting sleeves and lock nuts are provided on both sides of the support shaft to restrict the movement of the geotextile roll. The limiting sleeves and lock nuts are located inside and outside the frame sleeve, and the limiting sleeves are fixed to the support shaft by locking screws.

[0022] The limiting sleeve is a ring-shaped structure fitted onto the support shaft, with its inner diameter forming a transition fit with the outer diameter of the support shaft. The lock nut is a standard hexagonal nut, connected to the end of the support shaft via threads. The locking screw can be an M6 or M8 bolt, which passes through the threaded hole on the side wall of the limiting sleeve and tightens against the surface of the support shaft.

[0023] This technical solution effectively solves the problem of axial movement of geotextile rolls during laying by setting adjustable limiting mechanisms on both sides of the support shaft. The cooperation between the limiting sleeve and the locking nut achieves axial positioning of the geotextile roll, with the locking screw providing reliable fixing force. Compared with methods that rely solely on friction fixing, this structure has higher positioning accuracy and stability, ensuring accurate alignment during geotextile laying. Therefore, the geotextile will not shift during laying, guaranteeing the stability of the laying quality.

[0024] Furthermore, this application also proposes a specific structure for the guiding mechanism. The guiding mechanism includes a support rod that is slidably connected to the crossbar of the L-shaped guide rod, a rotating rod that is rotatably connected to the support rod, an indicator wheel that is mounted on the lower part of the rotating rod, and the tail of the rotating rod that is connected to the support rod via a compression spring.

[0025] Specifically, the support rod is slidably connected to the crossbar of the L-shaped guide rod via a sliding sleeve. A locking screw on the sliding sleeve is used to fix the position. The position of the guide mechanism can be adjusted by sliding the support rod along the L-shaped guide rod. The constant downward pressure provided by the compression spring ensures that the indicator wheel always remains in contact with the edge of the adjacent laid geotextile, thereby accurately controlling the overlap width. Compared with manual laying, this mechanism can precisely control the overlap width, improving laying quality and efficiency.

[0026] Furthermore, this application proposes that one end of the support rod is slidably connected to the L-shaped guide rod via a sliding sleeve, and a locking screw is provided on the sliding sleeve, which realizes the quick positioning and fixing of the support rod on the L-shaped guide rod. When it is necessary to adjust the position of the guide mechanism, simply loosen the locking screw to slide the support rod laterally along the L-shaped guide rod, and then re-lock it to maintain stability. This allows adjustment of the overlap spacing between the indicator wheel and the adjacent geotextile.

[0027] Furthermore, this application also proposes that the support rod has a rotating hole, and a rotating disk is optionally installed in the rotating hole, with the rotating disk and the rotating rod being integrally set.

[0028] The rotating hole is a through-hole structure set on the support rod, used to accommodate the rotating disk and realize the rotational support function. This ensures stable rotation of the rotating rod on the support rod. The rotating disk, as an intermediate support component, effectively reduces the swaying problem of the rotating rod.

[0029] Furthermore, this application also proposes that the support frame has an opening at the front end and that the rear end of the support frame is equipped with a lug plate that can be connected to a loader.

[0030] Specifically, the open front design of the support frame facilitates the loading, unloading, and replacement of geotextile rolls. The rear ear plate structure ensures a reliable connection with the loader. Compared to manual laying, this design utilizes the stable traction provided by the loader to ensure smooth movement during the laying process. Simultaneously, the open front structure avoids the cumbersome disassembly required by traditional closed frames, significantly improving construction efficiency. This solution effectively solves the technical problems of low efficiency and difficulty in guaranteeing laying quality in manual laying.

[0031] The implementation principle of a road geotextile laying device according to an embodiment of this application is as follows:

[0032] When installing geotextile roll 4, first install the support frame 1 at the front end of the loader 14 through the ear plate. Operate the loader 14 to position the support frame 1 on the top of the geotextile roll 4 and move it down. Insert the support shaft 3 along the frame sleeve 2 into the center of the geotextile roll 4. Tighten the limit sleeve 5 and double lock nut to fix it. In this way, the geotextile roll 4 does not need to be moved. You only need to operate the loader 14 to move the support frame 1.

[0033] After installation, operate the loader 14 to lay the geotextile along the road. Once the pre-lay geotextile 15 is completed, lay the subsequent overlapping post-lay geotextile 16. Before laying, loosen the locking screw of the sliding sleeve 7 and adjust the distance from the indicator wheel 11 to the end of the geotextile roll 4. This distance is the width of the overlap area 17 (e.g., ...). Figure 3 As shown), after adjustment, operate the loader 14 to press the indicator wheel 11 of the front guide mechanism onto the edge of the front geotextile 15. Move the loader 14 forward to push the geotextile roll 4 to rotate and realize the laying of the geotextile. As long as the driver of the loader 14 observes and operates the indicator wheel 11 to move along the edge of the front geotextile 15, the width of the overlap area 17 can be guaranteed to be consistent, which solves the problems of low efficiency and poor quality of manual laying.
