Description

Technical Field

[0001] The utility model relates to the technical field of geotextiles, and particularly relates to a fixing device for geotextiles. Background Art

[0002] Geotextiles, also known as geotextiles, are an important type of geosynthetic material. With their unique physical and chemical properties, they play an important role in multiple engineering fields and are widely used in fields such as water conservancy, highways, railways, construction, and environmental engineering. When in use, geotextiles need to be unfolded and laid flat on the foundation. Since the single-piece area of geotextiles is very large, wrinkles are likely to occur during laying, so it is necessary to fix the geotextiles to facilitate construction by workers. However, existing fixing devices generally only use simple anchor rods and pressing plates for fixation. When the geotextiles are subjected to lateral forces, they are likely to break away and cause the geotextiles to shift, increasing the laying difficulty and workload.

[0003] Chinese patent document CN220952853U discloses a geotextile fixing device, which includes a lower pressing plate, an upper pressing plate, and a plurality of fixing wedges. The upper surface of the lower pressing plate is provided with two screw rods and a plurality of lower convex ribs. Both screw rods are fitted with nuts. The plurality of lower convex ribs are spaced along the width direction of the lower pressing plate, and a lower gap is formed between adjacent two lower convex ribs. The upper pressing plate is provided with two positioning holes, and the two positioning holes are respectively sleeved on the two screw rods in a one-to-one correspondence. The lower surface of the upper pressing plate is provided with a plurality of upper convex ribs, and the plurality of upper convex ribs are spaced along the width direction of the upper pressing plate, and an upper gap is formed between adjacent two upper convex ribs. The plurality of fixing wedges are arranged on the lower surface of the lower pressing plate, which increases the contact area and acting force between the geotextile and the upper pressing plate and the lower pressing plate, and reduces the possibility of relative sliding of the geotextile under external forces. However, the above fixing device can only reduce the possibility of the geotextile sliding under lateral horizontal forces. When the geotextile is subjected to an obliquely upward force, the above fixing device still has the possibility of being pulled out. Therefore, the utility model proposes a geotextile fixing device that can cope with forces in multiple directions. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device for geotextiles, which reduces the possibility of the geotextile sliding under lateral and obliquely upward forces and improves the stability of geotextile laying.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A fixing device for geotextiles, comprising an upper pressing plate and a lower pressing plate.

The four corners of the lower pressing plate are provided with second inclined holes, and the four second inclined holes are all inclined along the diagonal of the lower pressing plate. The lower end of the first inclined hole is aligned and matched with the upper end of the second inclined hole. A ground nail is detachably arranged in the first inclined hole and the second inclined hole. A plurality of convex ribs are arranged in parallel at the bottom of the upper pressing plate, and a plurality of grooves matching the positions and shapes of the convex ribs are arranged at the top of the lower pressing plate.

[0007] As a preferred technical solution, the diameter of the first inclined hole is larger than the diameter of the ground nail, and the diameter of the second inclined hole matches the ground nail.

[0008] As a preferred technical solution, the second inclined hole is a threaded hole.

[0009] As a preferred technical solution, the surface of the ground nail is provided with threads, and the ground nail is threadedly connected with the second inclined hole.

[0010] As a preferred technical solution, a ground nail head is arranged at the top of the ground nail, and the diameter of the ground nail head is larger than the ground nail.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1.

[0013] 2. In the utility model, through four ground nails with different inclination directions, the ground gripping property of the device is improved, so that the geotextile is not easily detached and displaced when subjected to an obliquely upward pulling force.

[0014] 3. In the utility model, the structure is simple and the installation is convenient, which is convenient for workers to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment

[0026] Such as Figures 1-4As shown in the figure, a fixing device for geotextiles includes an upper pressing plate 1 and a lower pressing plate 2. Four first inclined holes 3 are provided at the four corners of the upper pressing plate 1, and the four first inclined holes 3 are all inclined along the diagonal of the upper pressing plate 1. Four second inclined holes 4 are provided at the four corners of the lower pressing plate 2, and the four second inclined holes 4 are all inclined along the diagonal of the lower pressing plate 2. The lower end of the first inclined hole 3 is aligned and matched with the upper end of the second inclined hole 4. A ground nail 5 is detachably arranged in the first inclined hole 3 and the second inclined hole 4. A plurality of convex ribs 7 are arranged in parallel at the bottom of the upper pressing plate 1, and a plurality of grooves 6 matching the positions and shapes of the convex ribs 7 are arranged at the top of the lower pressing plate 2.

[0027] It should be noted that the geotextile is clamped between the upper pressing plate 1 and the lower pressing plate 2 provided, which is convenient for fixing the geotextile. The first inclined hole 3 and the second inclined hole 4 provided provide an installation position for the ground nail 5. The ground nail 5 passes through the first inclined hole 3 and the second inclined hole 4 from bottom to top in sequence to fix the whole device and the geotextile on the foundation. The convex ribs 7 and the grooves 6 provided fix the geotextile to prevent the geotextile from detaching between the upper pressing plate 1 and the lower pressing plate 2.

[0028] In some feasible embodiments, the diameter of the first inclined hole 3 is larger than the diameter of the ground nail 5, and the diameter of the second inclined hole 4 matches the ground nail 5. Since the thicknesses of different geotextiles are different, the distance between the upper pressing plate 1 and the lower pressing plate 2 is not fixed, and the change in the distance between the two will cause the first inclined hole 3 and the second inclined hole 4 to be misaligned. The diameter of the first inclined hole 3 is increased, so that the ground nail 5 can match the second inclined hole 4 regardless of the thickness of the geotextile.

[0029] In some feasible embodiments, the second inclined hole 4 is a threaded hole, and the surface of the ground nail 5 is provided with threads. The ground nail 5 is threadedly connected to the second inclined hole 4, further increasing the pressure between the upper pressing plate 1 and the lower pressing plate 2 and improving the stability of the whole device.

[0030] In some feasible embodiments, a ground nail head is provided at the top of the ground nail 5. The diameter of the ground nail head is larger than that of the ground nail 5. The ground nail 5 is installed obliquely downward and rotated to be threadedly connected with the lower pressing plate 2. When rotated until the ground nail head abuts against the upper pressing plate 1 and continues to rotate, the ground nail head will cause the upper pressing plate 1 to move downward following the limiting action of the ground nail head until the upper pressing plate 1, the geotextile and the lower pressing plate 2 are closely attached together. At this time, the geotextile is fixed between the upper pressing plate 1 and the lower pressing plate 2.

[0031] When in use, first place the lower pressing plate 2 under the geotextile, then cover the upper pressing plate 1 on the geotextile, adjust to align the upper pressing plate 1 and the lower pressing plate 2, and then screw the ground nails 5 into the upper pressing plate 1 and the lower pressing plate 2 in sequence according to the diagonal order, and the fixing is completed.

[0032] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art. So far, the embodiments of the present disclosure have been described in detail. To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description. The scope of the present disclosure is defined by the appended claims.
