[0032] Please see Figures 1-5 This utility model provides a technical solution: a base fabric fixing device for frozen soil roadbed, including tie rods 2 fixedly connected to both ends of the base fabric 1, and multiple pointed objects are installed on the side of the two tie rods 2 facing away from the base fabric 1.

[0033] In this scheme: tie rods 2 are fixedly connected to both ends of the base fabric 1, and multiple pointed objects are installed on the side of the two tie rods 2 facing away from the base fabric 1. After the base fabric 1 is laid on the frozen soil subgrade, it is fixed to the frozen soil subgrade by the multiple pointed objects, so that the base fabric 1 is more firmly fixed to the frozen soil subgrade.

[0034] The base fabric 1 is typically made of high-strength, low-temperature resistant materials, such as polyester and polypropylene. These materials not only have good waterproof properties but also resist freeze-thaw cycles at low temperatures, ensuring the stability of the roadbed structure.

[0035] In this embodiment: both ends of the pull rod 2 are fixedly connected to a first rotating shaft 3, and both first rotating shafts 3 are rotatably connected to a connecting rod 4, and both connecting rods 4 are fixedly connected to the base fabric 1.

[0036] In this scheme: First rotating shafts 3 are fixedly connected to both ends of the tie rod 2, and two connecting rods 4 are rotatably connected to the corresponding first rotating shafts 3. Both connecting rods 4 are fixedly connected to the base fabric 1. By adjusting the included angle between the two connecting rods 4 and the tie rod 2, the base fabric 1 is made to fit snugly against the edge of the roadbed, thus adapting to different roadbed cross-sections.

[0037] In this embodiment, a locking assembly is installed at the connection between the connecting rod 4 and the pull rod 2.

[0038] In this solution: by installing a locking component at the connection between the connecting rod 4 and the tie rod 2, the included angle between the connecting rod 4 and the tie rod 2 can be fixed, reducing the probability that the base fabric 1 will be blown away by the wind after it is laid.

[0039] In this embodiment: a plurality of first grooves 5 are provided on the side wall of the connecting rod 4, and the plurality of first grooves 5 are evenly distributed around the first rotating shaft 3;

[0040] The locking assembly includes multiple pins 6, which are installed in corresponding first grooves 5. An elastic support assembly is installed between the multiple pins 6 and the side wall of the first groove 5. Multiple limiting grooves 7 adapted to the pins 6 are provided on the side wall of the pull rod 2. When the elastic support assembly is in a naturally extended state, one end of each of the multiple pins 6 is inserted into the corresponding limiting groove 7.

[0041] In this design: multiple first grooves 5 are formed on the side wall of the connecting rod 4, and these grooves 5 are evenly distributed around the first rotating shaft 3; multiple balls 6 are installed in corresponding first grooves 5, and an elastic support assembly is installed between the balls 6 and the side wall of the first grooves 5; multiple limiting grooves 7 adapted to the balls 6 are formed on the side wall of the pull rod 2; when the elastic support assembly is in its naturally extended state, one end of each ball 6 is inserted into the corresponding limiting groove 7. By rotating the connecting rod 4, the balls 6 are dislodged from the limiting grooves 7 under pressure. After adjusting the angle between the connecting rod 4 and the pull rod 2, the balls 6 are inserted into the limiting grooves 7 under the elastic force of the elastic support assembly, thus fixing the angle between the connecting rod 4 and the pull rod 2.

[0042] In this embodiment, the ends of the multiple balls 6 inserted into the corresponding limiting grooves 7 are all ball-shaped.

[0043] In this design, by setting one end of each of the multiple balls 6 inserted into the corresponding limiting grooves 7 to a ball head shape, the angle between the connecting rod 4 and the pull rod 2 is made easier to adjust.

[0044] In this embodiment: the elastic support assembly includes a spring 8 located in the first groove 5, and the two ends of the spring 8 are fixedly connected to the corresponding ball 6 and the side wall of the first groove 5, respectively.

[0045] In this design, the two ends of the spring 8 are fixedly connected to the corresponding ball 6 and the side wall of the first groove 5, respectively. By rotating the connecting rod 4, the multiple balls 6 are dislodged from the multiple limiting grooves 7 under their pressure. After adjusting the angle between the connecting rod 4 and the pull rod 2, the multiple balls 6 are inserted into the multiple limiting grooves 7 under the elastic force of the spring 8, thus fixing the included angle between the connecting rod 4 and the pull rod 2.

[0046] In this embodiment: the connecting rod 4 is fixedly connected to the side wall away from the base fabric 1 with a first nail 9.

[0047] In this scheme: the first nail 9 is fixedly connected to the side wall of the connecting rod 4 away from the base fabric 1. The workers fix the base fabric 1 more firmly to the frozen soil subgrade by nailing the first nail 9 to the frozen soil subgrade.

[0048] In this embodiment: the pull rod 2 has a plurality of second grooves 10 on the side wall away from the base fabric 1, and a second rotating shaft 11 is fixedly connected in each of the plurality of second grooves 10, and a roller 12 is rotatably connected on each of the plurality of second rotating shafts 11.

[0049] In this design, multiple second grooves 10 are formed on the side wall of the pull rod 2 away from the base fabric 1. Each of the multiple second grooves 10 is fixedly connected to a second rotating shaft 11, and each of the multiple second rotating shafts 11 is rotatably connected to a roller 12. This reduces the resistance when pulling the base fabric 1 and facilitates adjustment of the base fabric 1's position.

[0050] In this embodiment: the pointed object is the second nail 13, and the upper end of the second nail 13 is rotatably connected to the bottom of the pull rod 2.

[0051] In this design: the pointed object is the second nail 13, and the upper end of the second nail 13 is rotatably connected to the bottom of the tie rod 2. When adjusting the position of the base fabric 1, the second nail 13 is adjusted to a horizontal position, which makes it easier to pull the base fabric 1. When the base fabric 1 is fixed on the frozen soil subgrade, the second nail 13 is adjusted to a vertical position, so that the base fabric 1 is firmly fixed on the frozen soil subgrade.

[0052] In this embodiment: a pull rope 14 is provided on the pull rod 2, and both ends of the pull rope 14 are fixedly connected to the pull rod 2.

[0053] In this solution: a pull rope 14 is fixedly connected to the pull rod 2. Workers can move the base fabric 1 by pulling the rope 14, reducing the time spent bending over and improving comfort. Furthermore, during transportation, the rope can be tied to the outer ring of the base fabric 1 to prevent it from unraveling during transport.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
