Description

Technical Field

[0001] This utility model relates to the field of geogrid paving technology, and in particular to a traction geogrid paving device. Background Technology

[0002] Multi-layer geogrids (geotextiles) must be laid in the roadbed filling of highway engineering to enhance the integrity of the roadbed structure and reduce the risk of quality accidents such as roadbed cracking and landslides. There are various methods for laying roadbed geogrids, but the manual laying method is currently the most commonly used.

[0003] The manual paving method for geogrids is commonly used in Class I roadbed filling construction in highway engineering. This method involves using transport machinery to first lay the geogrids at designated points, followed by manual labor to unfold and spread the geogrid rolls according to design requirements. Manual geogrid paving typically requires 5-7 people, who must work together to unfold and spread the geogrid rolls. Due to the significant weight of the geogrid, manual paving is time-consuming and labor-intensive. Studies have shown that manual paving of one kilometer of geogrid takes 42.89 hours, significantly impacting the subsequent roadbed earthwork filling progress. Furthermore, the large number of workers and the long paving time result in higher labor costs and extend the project construction period. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a traction-type geogrid paving device, which is achieved through the following technical solution: A traction-type geogrid paving device includes a traction bracket, the traction bracket including a rectangular base frame, an extension plate on the left and right front sides of the base frame, a front support plate on the front side of the base frame and a rear support plate on the rear side, a storage basket above the front support plate, the bottom of the storage basket being fixedly connected to the front support plate, the storage basket including several horizontally arranged arc-shaped pockets, and the top of the front and rear sides of all the pockets being connected to horizontal connecting plates.

[0005] The bottom frame has a support plate on each of its left and right sides, and each support plate has a bearing on its top. A rotating shaft is connected between the two bearings, and a paving roller is mounted on the rotating shaft.

[0006] As a preferred embodiment, each of the four corners of the traction bracket is provided with a traveling wheel.

[0007] As a preferred embodiment, each of the aforementioned support uprights is provided with a support inclined plate between it and the base frame.

[0008] As a preferred embodiment, the front support plate is provided with symmetrical connecting rings on the left and right sides.

[0009] As a preferred embodiment, a connecting plate is provided in the middle between the front support plate and the rear support plate.

[0010] Compared with existing technologies, the advantages of this invention are: This invention enables automatic paving of geogrids. The roll of material to be paved is placed in a storage basket. According to the design requirements for paving geogrids for highway subgrades, professional technicians measure the placement points, pull out one end of the roll, pass it around the paving roller, compact it, and fix it to the pre-measured placement point on the paving surface. After checking that all components of the paving device are stable and reliable, the paving device is pulled by a traction device to begin mechanized geogrid paving construction. This improves construction efficiency and saves time and labor.

[0011] The paving roller and the support plate are connected by bearings, which allows the paving roller to rotate freely when paving the geogrid, reducing the rotational friction during the paving process. The inclined support plate enhances its stability. Each of the four corners of the traction bracket is equipped with a wheel for easy movement and to ensure good stability of the device during the paving process. The bottom of the storage basket is fixedly connected to the front support plate to ensure that the storage basket does not move during traction and movement, thereby maximizing the construction quality of the geogrid paving of the highway subgrade.
