[0002] The laying of geotextile, a waterproof material used in highway anti-seepage projects, is of great importance. Since these waterproof materials are generally heavy, hard and large in area, it is very inconvenient to operate during construction, so auxiliary equipment is needed to assist in laying.

[0003] Through the piston movement of the two hydraulic cylinders, the geotextile laying drum shaft, hollow round steel and brush are controlled to complete the geotextile laying facing the highway anti-seepage project. When the oil inlet of the upper part of the hydraulic cylinder body I inputs pressure oil, the oil inlet of the rod cavity inputs oil, the piston rod I moves downward, the rotating arm I hangs down, the oil inlet of the right side of the hydraulic cylinder body II inputs pressure oil, the oil inlet of the rod cavity inputs oil, the piston rod II moves left, drags the hinge V to rotate counterclockwise, and through the rotation of the hinge VI, the longitudinal connecting rod is lifted counterclockwise, the geotextile laying drum shaft rises to the working position, the brush rotates counterclockwise, and is tightly pressed on the surface of the highway, at the same time, the supporting rod and hollow round steel on the brush rod are counterclockwise, and the function of fixing the geotextile is achieved. The invention is simple to operate, and adopts mechanized operation for laying geotextile on the surface of the highway, which is convenient and fast for laying geotextile on a large area.

[0004] In the above technical solution, during the laying of the geotextile, the side edges of the geotextile are not corrected, so manual correction is needed, which seriously affects the laying efficiency of the equipment, and the geotextile cannot be fixed after laying, which causes the geotextile to deviate during laying due to the influence of typhoons or other external forces. Therefore, we propose a highway anti-seepage geotextile laying method. SUMMARY

[0040] 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.

[0041] Example 1:

[0042] like Figures 1-11As shown in the figure, an embodiment of the present invention provides a method for laying anti-seepage geotextile on highways, including the following steps:

[0043] S1, Roadbed cleaning work: A cleaning vehicle is used to clean the stones and other impurities on the roadbed surface. Then, a high-pressure water gun from the cleaning vehicle is used to wash away the dust on the roadbed surface. After the water stains on the roadbed surface have dried, the next step is carried out.

[0044] S2, Roadbed width measurement and calculation: The width of the roadbed surface is measured using measuring tools. The width of the geotextile 6 is adjusted according to the roadbed width. When the road width is greater than the width of two or more geotextiles 6, the width of the geotextile 6 is used as a reference to draw lines on the roadbed. This allows the amount of geotextile 6 used to be calculated during the laying process, reducing the overlap width of adjacent geotextiles 6.

[0045] S3, Roadbed marking work, using a marking machine to mark lines according to the width of geotextile 6 in step S2 above;

[0046] S4, Geotextile adjustment operation: An auxiliary device is used to assist workers in laying geotextile 6. During the laying of geotextile 6, the visual monitoring probe 79 scans the baseline 2 drawn in step S3 above and transmits the scanned data to the positioning control module 710. The positioning control module 710 compares the scanned information to locate the position of the baseline 2. The positioning control module 710 controls the geotextile positioning adjustment component 7 to drive and adjust the position of geotextile 6 according to the scanned positioning data, adjusting geotextile 6 towards the baseline 2. This can perform positioning and alignment of geotextile 6 and reduce the occurrence of bending.

[0047] S5, Geotextile laying operation, using the lowering motion of laying component 8 to press geotextile 6 onto the surface of subgrade 1;

[0048] S6, Geotextile fixing operation, the geotextile fixing component 9 passes steel nails through the geotextile 6 and nails them into the roadbed 1.

[0049] In this embodiment, the output end of the positioning electric push rod 78 is connected to the movable seat 75. When the positioning electric push rod 78 works, it pushes the movable seat 75 to move along the guide rod 74. The fixed shaft 76 located on the movable seat 75 and the fixed seat 73 drives the two positioning rotating sleeves 77 to come together to clamp and position the geotextile 6.

[0050] In this embodiment, the adjusting electric push rod 72 located on the lower side of the fixed seat 73 drives the fixed seat 73 to move the geotextile 6 towards the baseline 2, positioning the corners of the geotextile 6. The adjusting electric push rods 72 on both sides drive the two fixed seats 73 to move away from each other, straightening the two sides of the geotextile 6 and preventing the geotextile 6 from wrinkling and overlapping.

[0051] In this embodiment, the cylinder 85 located inside the frame 3 is activated to drive the mounting bracket 81 to move along the slide blocks 83 and slide rails 84 on both sides, and the laying roller 82 contacts the surface of the geotextile 6 to press the geotextile 6 onto the roadbed surface.

[0052] In this embodiment, the steel nail vibrating feeding plate 91 located inside the frame 3 vibrates and moves the internal steel nail 95 into the groove 934 of the rotating member 933 in the inclined guide channel 92, where it is blocked by the rotating member 933. The drive motor 935 drives the rotating shaft 932 to move the rotating member 933, rotating the steel nail 95 that has moved into the groove 934 to the end of the inclined guide channel 92 and dropping it into the limiting ring 96. The bending part 962 limits the steel nail 95. The punching cylinder 97 located inside the frame 3 drives the punch 99 to move into the limiting ring 96, thereby pushing the steel nail 95 through the geotextile 6 and nailing it into the roadbed 1 to complete the fixing work.

[0053] Example 2

[0054] Please see Figures 1-5 As shown, an auxiliary device for a method of laying geotextile for highway seepage prevention is provided. The auxiliary device includes a frame 3. A take-up shaft mounting seat 4 is fixedly installed at one end of the frame 3. A geotextile take-up shaft 5 is rotatably installed inside the take-up shaft mounting seat 4. Geotextile 6 is wound on the geotextile take-up shaft 5. A geotextile positioning and adjusting component 7 is installed on the lower surface of the frame 3 near the take-up shaft mounting seat 4. A geotextile fixing component 9 is installed on the lower surface of the frame 3 away from the take-up shaft mounting seat 4. A laying component 8 is installed on the lower surface of the frame 3 between the geotextile fixing component 9 and the geotextile positioning and adjusting component 7.

[0055] In this embodiment, the geotextile positioning and adjustment assembly 7 includes two fixed brackets 71, which are respectively fixedly installed on both sides of the lower surface of the frame 3. An adjusting electric push rod 72 is fixedly installed on each fixed bracket 71. A fixed seat 73 is fixedly installed at the output end of the adjusting electric push rod 72 via the bracket. A guide rod 74 is fixedly installed at one end of the upper surface of the fixed seat 73. A movable seat 75 is slidably installed on the guide rod 74. Fixed shafts 76 are fixedly installed on both the movable seat 75 and the fixed seat 73. A positioning rotating sleeve 77 is rotatably installed on the outer wall of the fixed shaft 76. A positioning electric push rod 78 is fixedly installed at the upper end of the guide rod 74. The output end of the positioning electric push rod 78 is fixedly installed on the fixed seat 73. A visual monitoring probe 79 is installed on one side of the fixed seat 73. A positioning control module 710 is installed on the visual monitoring probe 79. The positioning electric push rod 78 can push the movable seat 75 to move along the guide rod 74, thereby driving the upper positioning sleeve 77 to move downward to the lower sleeve, thus clamping and fixing the geotextile 6. The visual monitoring probe 79 scans the baseline 2 on the surface of the roadbed 1 and transmits the scan data to the positioning control module 710. The positioning control module 710 compares and analyzes the scan information to locate the position of the baseline 2. The positioning control module 710 controls the electric push rod 72 to adjust the position of the geotextile 6 according to the scan positioning data, adjusting the geotextile 6 towards the baseline 2 reference line, which can perform positioning and alignment of the geotextile 6 and reduce the occurrence of bending.

[0056] In this embodiment, the laying component 8 includes a mounting bracket 81, with slide blocks 83 fixedly mounted at both ends of the mounting bracket 81. Each slide block 83 has a slide rail 84 slidably mounted inside it. The slide rail 84 is fixedly mounted on the inner wall of the frame 3. The upper surface of the mounting bracket 81 is fixedly connected to the output end of the cylinder 85. The cylinder 85 is fixedly mounted on the inner wall of the frame 3. In use, the output end of the cylinder 85 drives the mounting bracket 81 to move along the slide blocks 83 and the slide rail 84, causing the laying roller 82 installed in the mounting bracket 81 and inside it to move downward. The laying roller 82 presses the geotextile 6 onto the surface of the roadbed 1 to facilitate the subsequent fixing of the geotextile 6.

[0057] In this embodiment, to improve the fixing effect of the geotextile 6 and enhance the tightness of the connection between the geotextile 6 and the roadbed, the geotextile fixing assembly 9 includes a steel nail vibratory feeding plate 91. The steel nail vibratory feeding plate 91 is fixedly installed inside the frame 3. An inclined guide channel 92 is fixedly installed at the outlet of the steel nail vibratory feeding plate 91. The inclined guide channel 92 consists of two parallel guide plates 93, and a guide groove 94 is formed between the two guide plates 93. After the steel nail 95 enters the inclined guide channel 92, the top of the steel nail 95 is limited by the two guide plates 93, and the lower end of the steel nail 95 is located inside the guide groove 94. Under the influence of gravity, the steel nail 95 slides towards the end along the inclined guide channel 92. The lower side of the end of the inclined guide channel 92 is fixedly installed. A limiting ring 96 is provided, and spring sheets 961 are fixedly installed on the lower surface of the limiting ring 96. The spring sheets 961 are made of elastic metal sheets. The lower end of the spring sheets 961 extends towards the center of the limiting ring 96 with a bent portion 962. The distance between several bent portions 962 is less than the head of the steel nail 95. The bent portions 962 limit the head of the steel nail 95 to prevent the steel nail 95 from falling directly onto the surface of the geotextile 6. A contact sensor is installed in one of the bent portions 962. After the steel nail 95 falls to the bent portion 962, the contact sensor transmits a signal to the controller 98, thereby activating the punch cylinder 97. The punch 99 can push the steel nail 95 downward, thereby causing the spring sheet 961 to bend under force, allowing the steel nail 95 to pass through. The spring sheet 961 moves towards the geotextile 6 through the bent portion 962. One of the guide plates 93 has an installation groove 931 inside, and a rotating shaft 932 is rotatably mounted inside the installation groove 931. A rotating component 933 is fixedly mounted at the center of the rotating shaft 932. The outer wall of the rotating component 933 has a circular array of grooves 934, the shape of which matches the shape of the steel nail 95. The rotating shaft 932 drives the rotating component 933 to rotate, moving the steel nail 95 inside the grooves 934 above the limiting ring 96. A stamping cylinder 97 is fixedly mounted inside the frame 3 above the limiting ring 96. A punch 99 is fixedly mounted at the output end of the stamping cylinder 97. A controller 98 is mounted outside the stamping cylinder 97. The steel nail is located inside the frame 3. The vibrating feeding plate 91 vibrates and moves the internal steel nail 95 into the inclined guide channel 92, and slides it into the groove 934 of the rotating part 933 at the bottom of the inclined guide channel 92. It is blocked by the rotating part 933. The drive motor 935 drives the rotating shaft 932 to move the rotating part 933, which rotates the steel nail 95 that has moved into the groove 934 to the end of the inclined guide channel 92 and falls into the limiting ring 96. The bending part 962 limits the steel nail 95. The punching cylinder 97 located inside the frame 3 drives the punch 99 to move into the limiting ring 96, thereby pushing the steel nail 95 through the geotextile 6 and nailing it into the roadbed 1 to complete the fixing work, which improves the fixing effect of the geotextile 6 and the tightness of the connection between the geotextile 6 and the roadbed.

[0058] Working principle:

[0059] When in use, first pull the end of the geotextile 6 to the bottom of the laying component 8, press the geotextile 6 with the laying component 8 to position it, and move the frame 3 forward to fix the end of the geotextile 6 with the geotextile fixing component 9.

[0060] The visual monitoring probe 79 scans the baseline 2 on the surface of the roadbed 1 and transmits the scanned data to the positioning control module 710. The positioning control module 710 compares and analyzes the scanned information to locate the position of the baseline 2. Based on the scanned positioning data, the positioning control module 710 controls the electric push rod 72 to adjust the position of the geotextile 6, adjusting the geotextile 6 towards the baseline 2. This allows for the positioning and alignment of the geotextile 6, reducing the occurrence of bending.

[0061] The drive motor 935 drives the rotating shaft 932 to move the rotating part 933, which rotates the steel nail 95 that has moved into the groove 934 to the end of the inclined guide channel 92 and falls into the limiting ring 96. The bending part 962 limits the steel nail 95. The punching cylinder 97 located inside the frame 3 drives the punch 99 to move into the limiting ring 96, thereby pushing the steel nail 95 through the geotextile 6 and nailing it into the roadbed 1 to complete the fixing work, which improves the fixing effect of the geotextile 6 and improves the tightness of the connection between the geotextile 6 and the roadbed.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
