[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 5 The geotextile construction device shown in the figure comprises: a support mechanism 1 and a roller mechanism 2. Figure 1 and Figure 2As shown, the support mechanism 1 has a vertical support 11; the roller mechanism 2 has a central rolling shaft 21, and a first steel tube 22 is provided on the outer sleeve of the central rolling shaft 21. The space between the first steel tube 22 and the central rolling shaft 21 is filled and fixed with mortar 23. The first steel tube 22 is configured to be shorter than the length of the central rolling shaft 21 so that both ends of the central rolling shaft 21 extend out; wherein, both ends of the central rolling shaft 21 are at least each mounted on one vertical support 11 and arranged to roll. The central rolling shaft 21 is used to bear the main force of rolling. The first steel tube 22 is provided on the outer side of the central rolling shaft 21, and the space between the two is filled and fixed with mortar 23, in order to enhance the bonding strength between the steel tube and the rolling shaft and avoid loosening or slipping during use. The length of the first steel tube 22 is designed to be shorter than the length of the central rolling shaft 21, so both ends of the central rolling shaft 21 will extend out from the end of the first steel tube 22, so that both ends of the central rolling shaft 21 can be easily installed with the vertical support 11. As shown in FIG. Figure 5 As shown, both ends of the central rolling shaft 21 can rotate freely at the support, thereby realizing the rolling function of the roller mechanism 2, making it easier for the fabric to be evenly unfolded and stretched during construction.

[0024] In the above embodiment, the present invention enables the geotextile to be smoothly unfolded by setting the roller mechanism 2, the setting of the vertical support 11 ensures the stability of the device, and the setting of the mortar 23 filling enhances the strength of the roller and reduces the wear during long-term use; compared with the prior art, the work efficiency of laying geotextile on soft soil foundation is improved.

[0025] In an embodiment of the present invention, in order to improve the stability of the device, Figure 3 As shown, the support mechanism 1 also has a bottom plate support 12, and the bottom plate support 12 is connected to the bottom of the vertical support 11. By increasing the contact area of ​​the bottom, a more stable basic support is provided for the entire device, thereby preventing the device from tipping over or moving due to uneven ground or uneven load. The bottom plate support 12 and the vertical support 11 can be connected by welding, bolting, etc. The bottom plate support 12 can also reserve a structure for fixing, such as a bolt hole, to facilitate fixing the device to the ground at the construction site. By adding the bottom plate support 12, the support mechanism 1 is expanded from a simple vertical support 11 to a dual-functional design with both vertical support and basic support, thereby improving the stability and applicability of the device.

[0026] In the embodiment of the present invention, in order to further optimize the bottom plate support 12, please continue to refer to Figure 3, the bottom plate support 12 is set in a cross shape. The cross shape means that the bottom support plate is composed of two mutually perpendicular support plates, which are distributed along the X-axis and Y-axis directions on the horizontal plane, so as to provide uniform support coverage. Under soft, uneven or uneven ground conditions, the cross-shaped bottom plate support 12 can better adapt to terrain changes and keep the device stable. For larger or heavier geotextile construction devices, the cross-shaped bottom plate support 12 provides stronger support capacity and structural strength. For the choice of materials, both the vertical support 11 and the bottom plate support 12 can adopt I-beams or H-shaped steels. Compared with a single bottom plate support 12 or other support plates of simple shapes, the cross-shaped bottom plate support 12 has a wider support area, can evenly disperse the weight of the device, reduce the impact of local pressure on the ground, and can effectively resist the risk of overturning due to external force or uneven ground.

[0027] In the embodiment of the present invention, in order to ensure the rotation ability of the central rolling axis 21, as Figure 2 and Figure 3 As shown, the support mechanism 1 also has a first bearing 13, and the first bearing 13 is arranged at the center of the top surface of the vertical support 11. The center position of the top surface is the key point for the installation of the rolling shaft. By installing the bearing at the center, it can be ensured that the axis of rotation of the rolling shaft is completely aligned with the support mechanism 1, thereby improving the stability and accuracy of the overall structure. Among them, the first bearing 13 can be selected from ball bearings, deep groove ball bearings or other types of bearings suitable for rotation. The specific selection depends on the size, load requirements and rotation speed of the rolling shaft. In an actual construction environment, in order to prevent dust from entering or damaging the bearing, a sealing design, such as a bearing housing or a dust cover, may be provided to ensure that the bearing can work normally in harsh environments. The first bearing 13 greatly reduces the rotational resistance of the rolling shaft by rolling instead of sliding, thereby improving the operating efficiency of the construction device.

[0028] In the embodiment of the present invention, the structure and performance of the support mechanism 1 are further optimized. Please continue to refer to Figure 2 and Figure 3 The support mechanism 1 also has a second bearing 14, and there are two second bearings 14 that are symmetrically arranged on the sides of the top surface of the vertical support 11. The two second bearings 14 are symmetrically arranged to ensure that the rotational force of the rolling shaft is more uniform and avoid the unbalanced load problem that may be caused by single-point support. Compared with relying solely on the first bearing 13, adding two second bearings 14 can provide additional support points and disperse the load of the rolling shaft, especially in the case of long rolling shafts or large loads, significantly improving the load-bearing capacity and stability of the overall device. The first bearing 13 is located at the center of the top surface of the vertical support 11 to provide the main rotation fulcrum; the second bearings 14 are distributed on the sides for auxiliary support and load dispersion. The three work together to ensure the stability of the rolling shaft in multiple directions.

[0029] In the embodiment of the present invention, in order to further improve the roller mechanism 2, as shown in FIG. Figure 4 As shown, the roller mechanism 2 also includes a second steel tube 24, which is concentrically arranged with the first steel tube 22, and the second steel tube 24 is sleeved outside the first steel tube 22. The second steel tube 24, as an external protective layer of the first steel tube 22, can greatly improve the overall strength and deformation resistance of the roller mechanism 2, and can also reduce the structural fatigue of the roller mechanism 2 caused by concentrated stress during use. In addition, since the first steel tube 22 and the second steel tube 24 are concentrically designed, this double-layer structure will not cause additional obstacles to the rotation performance of the roller, and can still maintain the smooth operation of the rolling shaft. The second steel tube 24 is concentrically sleeved with the first steel tube 22 to form a stronger and more stable double-layer roller structure, thereby improving the load-bearing capacity and durability of the roller mechanism 2.

[0030] In the embodiment of the present invention, the length of the second steel tube 24 is the same as the length of the first steel tube 22. Figure 1 As shown, the second steel tube 24 completely covers the first steel tube 22 from both ends, forming a double-layer tube structure of equal length, ensuring that each part of the roller mechanism 2 can be evenly protected and supported by the double-layer steel tube, and the strength or functional performance will not be affected by the local length difference, and the exposed part will not be directly affected by the external environment such as corrosion, wear, etc.

[0031] In the embodiment of the present invention, in order to reflect the structural strength of the roller mechanism 2, as shown in FIG. Figure 4 As shown, the first steel pipe 22 and the second steel pipe 24 are filled and fixed with mortar 23. The mortar 23 not only serves to connect and fix, but also improves the rigidity and stability of the roller to a certain extent. The double-layer steel pipe structure filled with mortar 23 can more effectively absorb the vibration generated during the construction process and reduce the noise and shaking during the operation of the roller mechanism 2. As a plastic material, the mortar 23 can well fill the irregular gaps between the double-layer steel pipes to form a tight combination. In this embodiment, the problems that may be caused by the gap between the double-layer steel pipes are solved, and the durability and adaptability of the roller are improved.

[0032] In the embodiment of the present invention, the roller mechanism 2 is further optimized, such as Figure 4 As shown, the roller mechanism 2 also has a reinforcing rib 25, which is arranged inside the central rolling shaft 21. The reinforcing rib 25 is embedded in the central rolling shaft 21 and is evenly distributed along the axial or radial direction of the central rolling shaft 21 to form a support for the inner wall of the rolling shaft. Compared with directly thickening the wall of the central rolling shaft 21, the built-in reinforcing rib 25 can not only greatly improve the rigidity, but also reduce the deadweight of the rolling shaft. The built-in reinforcing rib 25 of the roller mechanism 2 greatly improves the structural strength, durability and stability by providing additional support inside the central rolling shaft 21.

[0033] The present invention also provides a method for using the geotextile construction device, such as Figure 6 As shown, the following steps are included: S10: inserting the roller mechanism 2 into the geotextile roll; S20: placing the roller mechanism 2 inserted into the geotextile roll on the vertical support 11; S30: Pulling the end of the geotextile to rotate the geotextile on the supporting mechanism 1 to gradually complete the spreading of the geotextile.
